Notes

Before signing a DCD certificate confirm:

• Firms insurance policy explicitly covers employees acting as registered design practitioners
• Ensure the policy does not exclude claims arising from the Design and Building Practitioners Act 2020
• Ask for and keep a COC (certificate of currency)

Also:

• Check the NCC and specific year required by the Constitution Certificate
• Check integration between all designs
• Make sure your design is based on the Current Coordination Set

Process for issuing a DCD and RDR drawings:

1. Provide the DCD and regulated designs to the principal design practitioner.
2. Explicitly state that construction on this variation/design must not commence until this DCD is lodged.
3. Request the builder to supply a lodgement receipt or reference number.
4. Keep a copy of the DCD, regulated design, and issue email to prove that you have fulfilled your responsibility.

To convert from Earthquake ULS deflection to SLS deflection:

d_SLS = d_ULS * C₂₅/C₅₀₀ / mu

We divide by mu because at ULS we are saying the deflection is mu times the elastic limit for deflection.

C₂₅/C500 is usually k₂₅/k₅₀₀ = 0.25 / 1.0 = 0.25

Note, k₂₅ = 0.25 is in older vertsion of AS 1170.4 standard.

5.5.2(b)(ii) The minimum slab thickness defined in Table 5.5.2(A) is required over a rectangular area extending 0.16 of the larger span length either side of a column in each direction from the column face. The depths in this table cannot be reduced by calculation methods in accordance with Clause 5.3.1(b). Outside this area, the minimum slab depths for insulation in Table 5.5. I for insulation apply.

Aaron Hazelton if you model it as a peno and it works then not a problemo as the FRL is a structural adequacy questions opposed to insulation. so if the slab works and spans with penetrations its ok from a structural adequacy perspective its up to the fire collar system to provide the insulation properties of the FRL etc,

Darius P James Maguire - Just be careful with this one, if the certifier knows what hes on about it he may knock it back, technically, Aaron is correct because provisions are made for this in the Eurocode (Treating them as penetrations), however, as per AS3600, this part of the code does not want you to use the Eurocode as defined in below snapshot of the code. For straight penetrations, I agree it actually is a penetration as is fine. The only comment i make is that you can not treat a thinner section of slab as a penetration.

• Title: Precast 102 The Fundamentals of structural design using precast
• Presenter: Sime Rogic
• Check load paths running down the building
• Cheapest way is to have light panels typ and heavy bottom floor strut rather than medium all the way
• Consider areas where you do not want load to come into panels
• Non-load bearing panels need to have slab designed to take load with particular care given to stripping sequences
• Dowel spacing to match multiple of panel reo if ties are used
• Make sure castins fit in panel
• Ensure panels do not span across PMJ/TMJ unless isolated on one side
• If panels are input as line loads, make sure to account for mass in lateral design
• 3.2m panel will fit on a truck, 4.2 but needs special permits for transport

★★★★

An Arthur C Clarke book about the city of Diapar, one of the two remaining human cities left on Earth. Some of the ideas in this book are amazing. Inhabitants live very long lives and when they 'die' they return to the memory banks, only to be reborn at a random later period in amongst a new combination of people. This is contrasted with the city of Lys where inhabitants have normal lifespans but have learnt telepathy for communication.

Both civilisations have been trapped on earth because of old legends about alien invasions where they promised that they would stay on earth, but this seems to be only a story used to keep the civilisations placid.

The main character Alvin finds a spaceship and travels, finding reminants of massive and interesting abandoned civilisation and that potentially these civilisations have travelled to other universes in search of resources.

The book's plot and characters are a little weak, but the scale and ideas are incredible. I originally rated the book 7/10 but after resting on it I think it deserves an 8/10.

Brad Pitt is an astronaut who travels to his long thought lost Dad and his ship. Entertaining, but not much in the way of takeaways.

• Presenter: Dave Southgate
• All to use same font (ISOCPEUR)
• Use colours to emphasise

• Title: Basic Principles of Curtain Walls
• Presenter: Julian Sigmund
• Opaque and vision areas
• Larger opaque areas hide insulation and cover floor - results in more performance
• Structural silicon is not good for permanent/long term loading, setting blocks used to set in glass permanent load transfer
• Between floors require smoke and fire seals (hilti foam or blanket+rockwool)

• Title: Weather tightness and drainage
• Presenter: Julian Sigmund
• Leakage mechanisms: gravity, kinetic, surface tension, capillary, air currents, pressure diff
• Weep hole >8-10mm
• Gaskets for rain screen, air seal, fill gaps, noise/thermal insulation, friction reducer, setting/spacing
• Friction fit gaskets used overseas, in Australia can be pulled out by cockatoos

1. Calculation of maximum crack width for practical design of reinforced concrete - https://onlinelibrary.wiley.com/doi/full/10.1002/cend.202100004
   • Uncracked state (e=0-0.001) has high stiffness from concrete component
   • Crack formation (e=0.001-0.008) load transfers to steel
   • Stabilised crack (e>0.008) stiffness based on steel stiffness
   • Max steel strain is always subject to global force equilibrium es=F/(EsAs)

[From Dave Southgate]

1. De-stress tendon number TXX and TXX.
2. Breakout/scabble back all cracked concrete in effected zone.
3. Clean and remove any debris from surface and blow out with blower and wire brush.
4. Re-chair PT tendon TXX and TXX to achieve required cover.
5. HOLD POINT – INSERT BUILDER NAME to provide Indesco with photos to examine works prior to any further action.
6. Once Indesco have given approval, apply a steel primer such as PARCHEM Nitro Primer or equivalent to any exposed reinforcement.
7. Apply an epoxy based binding agent EPIREZ-133 or equivalent to the exposed concrete and patch with MP Rapid Set-60 or Masterflow 870.
8. Once concrete has reached it’s required compressive strength, carry out final stressing of tendon TXX and TXX.

• Title: Special Cladding Typologies
• Presenter: Julian Sigmund
• Cladding is external skin to a building
• Main function is rain screen
• Porous material: cavity behind drains and sun dries it out
• Sealed construction: sealed on outside assuming only small amount of water in, high maitenance as sealant joint is relied heavily on
• Rainscreen: vapour permiable but water inpermiable, needs ventilation to prevent condensation in cavity

• Title: SlabTec Remedial Capabilities
• Presenter: Haydn Kirrage, SlabTec
• Repurposing for changing load conditions or defect rectification
• CFRP laminates 1.2m x 0.6m x 1.2mm most common
• CFRP rods, fabrics, ropes, L plates
• Fabrics more common for wrapping columns
• Steel plate strengthening - for exceeding CFRP allowed limits
• CFRP has no fire resistance, need to go for steel
• Cantilever awning on Woolworths Wollongong done by SlabTec
• Carbon fibre, 3000 MPa strength. If prepared properly concrete-epoxy bond will not fail. Failure is always concrete tension pulloff. 1.5 MPa pulloff tension required. For 30 MPa+ this works fine
• CFRP better for construction - roll can be carried in
• Scaning:
  • Electromagnetic scanning once calibrated can tell bar size and cover
  • GPR radar for PT - can't see through reo at all so heavily reinforced can be hard to determine ($35k for machine)

• Title: Facade: Curtain wall typologies
• Presenter: Julian Sigmund
• Curtain walls are suspended/hanging/non load bearing facade
• Prefabricated offsite to high precision
• Stick wall system for hanging
• Cons: long term movement in structure can induce stress, acoustics/thermal travelling through levels
• Vertical sticks are mullions
• Temptation to close holes on site which can cause pressure inbalance
• Pressure solved by first water barrier then air barrier
• Gasket system quicker/reusable compared to structural silicon which is slow setting and more permanent
• Types:
  • Spandrel +ribbon glazing
  • Panelised curtain wall

1. Scan the existing concrete to locate reinforcement
2. Jackhammer back to solid concrete. All reinforcement to be left intact during rectification works.
3. Indesco to inspect.
4. Clean exposed reinforcement and treat with Epirez 133.
5. Proceed with patching in accordance with manufacturers specifications.

• Title: Temporary works applications and fastening
• Presenter: Damish Zuberi, Hilti
• Standards:
  • AS 1170.0 Design actions
  • AS 3850.1&3 Prefab concrete
  • AS 5131 Steelwork erection
  • AS 1576.1 Scaffold
  • AS 5216 anchor standard

• Presenter: Aaron Hazelton
• For estimating project cost
• Only showing reo on plan
• Should all be below the initial budget rates provided
• Changes/additional need to communicate change to reo from the budgets
• If ever higher than budget rates it needs to be communicated before drawings are issued

• Long formed wall, high degree crack control, joints not required given but accept low degree of cracking
• RDR docs basically requiring as builts on the fly and should be accounted for in fees
• Importance levels non clear between II and III
• Wet areas fall within slab

• Precast panel S and M connectors
• Not much benefit from M, but S could save time welding stitch plates
• Integrity reo, Dave likes to get away with min required
• Always provide lacer in hook or cog
• Forklift/construction loading, add circle area (2.5 dia?) no load point load in middle, check worst spans

• Title: Combining seismic design with reinforced concrete structures
• Presenter: Scott Munter (CEO SRIA)
• Resilience: survive and recover more quickly from extreme events
• Flood, storm and cyclone much larger economic impact than earthquake
• Low risk, high consequence. All capital cities expected to have earthquake
• Syd earthquake in top 10 financial risk in Aus
• Min reo requirements of 3600 ensure ductility
• Earthquake design elastically for nominal static load
• Static depends on mu and Sp (Tbl 14.3)
• More ductility results in reduction of static load resisting requirement
• Integrity reo acting as tension membrane as top steel spalls off and bond disappears
• For perimeter columns additional tie back reo may need to be provided to control the buckling length (upcoming in standard?)
• Even in beam reo Asmin required? Check from SRIA?
• For moment resisting frames pay attention to min splice lengths through columns and fitment spacing requirements
• Closed ties required in plastic hinges
• Technical Note 8 and 9 SRIA cover integrity reo and beams
• Columns
• Short columns loose ductility (shortened by parapets/infill) and must be detailed accordingly
• Detailing consisted with required drift throughout the structure (drift compatibility)
• Detailing for IMRF columns, moment resisting of columns must be 20% greater than beam (strong col, weak beam)
• This provides good side sway rather than weak storey type failure
• Slabs as diaphrams
• Ensuring diaphram loads are passed through joints (collector reo)
• Consider designing transfers with mu = 1
• Direct load paths always preferred, but if not hard to justify greater ductilities
• Seismic movement joints allow for drift to avoid pounding
• Steel must be specified with certification (ACRS or equivalent)
• Sustainability = total emissions / life span, longer lasting structures will have less imapct on environment
• For a transfer, reverse integrity reo required? Maybe since the tension reo will delaminate

• AS 2890.1 Parking facilities Part 1 - Off street parking Barriers are constructed to prevent vehicles from running over the edge of a raised platform or deck in a multi-storey park. Required for drops >600mm Designed to AS/NZS 1170.1

• Title: Explaining concrete
• Presenter: Veritasium (youtube channel)
• Link: https://www.youtube.com/watch?v=rWVAzS5duAs&list=WL&index=2&pp=gAQBiAQB
• Roman cement used lime, not portland cement
• Was not mixed throughout so didn't fully set, this gave a self healing property once cracks penetrated the uncracked areas
• Modern cememnt all portland cement
• Needs to remain high humidity for best setting
• Aggregates don't have large effect on strength but can bring down the cost
• Lightweight aggregates can acheive lower densities (~17 kN/m3)
• Sets in ~4hr, soft drink can delay curing 1-2hr due to sugar content

12:25 Writing this from the top on the escarpment. Doing this hike solo while Alex and housemates are in Canberra for a tournament. The first km was a long consistent uphill slog. Then some awesome rock and views started to appear for the last half k. Definitely challenging but the path was easy to follow. View from the top is really cool and I can clearly see Forest Reach Bridge. Time to head down.

Project 9011 Green Square Stage 4 Excavation - IV

• SEA Independant verification
• Structural report by VDM did not provide the typical necessary results to assess against SW guidelines and calcs hid the fact that the culvert did not pass
• Pressure from client to get the report out same day
• It was discovered that the loading exceeded both the SW guidelines and in some cases the ULS strength under the post-development loading provided by geotech assessment
• Client notified about the issue. We positioned ourselves as not delaying the package submission but as saving the client time of submitting and having the development rejected by SW
• Resolution: geotechnical report was revised based on geotech IV recommendations that the original analysis was overly conservative. Under the revised loading the culvert passed the SW loading guidelines for SEA

An Isaac Asimov short story about a robot, Andrew Martins, who slowly gains sentience, first through the development of creativity. He uses his creativity to do some woodworking projects, making money and slowly building wealth and then buys his freedom. He begins to chase legal recognition for robots, but mostly himself. He moves into a synthetic body and begins to outlive his prior owners, the Martins. In order to finally be recognised as a man, he builds in mortality to his body and passes away on his 200th year.

Some questions about the book:

• What is consiousness?
• What is it to be a human?
• Does his final thought, about "Little Miss" indicate he has developed Love?
• Should we be polite to Siri/Google/Alexa?

Roko's basilisk is a thought experiment about the potential risks involved in developing artificial intelligence (AI). Its conclusion is that an all-powerful artificial intelligence from the future might retroactively punish those who did not help bring about its existence, including those who merely knew about the possible development of such a being.

A film by Jonah Hill about his therapist, his phylosophy and his tools. Profound. It was very deep. Phil Stutz was very good at metaphor abd changing perspective in situations. I think this would be a good film to revisit if I'm having a hard time with anything.

21:27 Today I feel fat and lazy. Also a bit sad hearing about Nan's loss of memory. It's time to wake up and start working towards goals. I'm in a good routine of rowing/exercise every day but I need to couple that with good eating habits. From now on I am sticking to three smaller portion meals and any snacks are just fruits or nuts. Time to start ticking off that healthy eating habits.

21:05 Today was an interesting day. Still going with dailuy rowing though it's getting hard after hiking at Currawong yesterday with Aurelie and Chris. Did some more work on the bedroom side table, and we did an early Valentine's dinner at Karma Tea house with some gelato and a walk after. I'm grateful for the walk, it gave me and Alex time to talk about a lot of things. It kind of reminds me of Steptember in 2021 when we did a lot of talking.

Started planning our Japan trip but it's a little overwhelming. Might do a little more tomorrow evening.

I also committed to feeding the fish daily. A little habit that I would like to cultivate and take off Alex's plate. Tomorrow morning I might take the clippers out and clear some of the weeds around the pond.

08:24 This morning at city beach there was a large pod of dolphins swimming offshore. Really amazing and makes me want to spend more spontaneous time outside.

20:11 February is the month of the rowing challenge. Did my first row today. 3x1km with a very high heart rate at 30spm. If like to see what it's like at the end of the month.

07:10 Cold shower challenge is going well and this month we have the cumulative rowing distance challenge which I'm going to put in a good nudge. Starting today with packing the gym gear and rowing after work, or at lunch.

07:18 Cold shower day 1. Not as bad as I thought, but still tough. I'm commiting to one week (through to Sunday).

21:39 Came across the idea of cold showers and I'm thinking of doing it. My immediate reaction is to shy away, but maybe hitting it head on will do some good.

07:59 Just thinking about being content in life. It's fulfilling to do work that has lasting effects. Doing stuff around the house is an example. I want to have this same feeling working on my health.

Today we went on a walk/exploration with Holly Gemma Andy Rosie Nicho Otto Matt Asaka. We went to Carrington Falls first and then crossed the river to Nellie's Glen swimming hole. It was pretty busy so we ended up going upstream from Nellie's Glen for a swim.

★★★★

About two Syrian sisters that make the journey to Germany as refugees and based on a true story. It's a powerful and emotional story.

20:14 Time to get hungry to achieve some health goals. Time to bring the focus and discipline. I know what I need to avoid and that's where it will start.

08:02 Just realised while watching a YouTube video that I've slipped on journalling and also starting to get more low quality screentime on the phone. Time to start turning that around. From now if I have the urge to grab my phone I'll come here and write a bit first.

07:12 This week went a bit lopsided. I think I need to be more mindful about what I'm doing around work. But mental strength isn't the problem, I think it might be about systems. For next week I will trial puzzling before work to fill up time. I also went too hard on the first run back resulting in two rest days. Need to tone it back, maybe some easy 3ks around the block followed by some balance or core.

Walked the Clover Falls Trail on Macquarie Pass. The carpark half way up was pretty full when we got there around 9. With Nicho, Gemma, Andy and Alex. First part very easy, then once you get down to the stream the path starts to get hard to find, we got lost a few times but made it to Clover Falls. The official path crosses just before the falls, but much easier to stay to the left on the way there.

• A 12 episode backstory on Cassian Andor and the beginnings of the Rebellion in Star Wars. This series was amazing. Atmospheric, and with a story that really drew me in. The story is on a human scale with no Jedi influences but explores some very interesting parts of the universe. I would even rate it higher than Mandalorian, I think.

17:33 Today we went whitewater rafting in Penrith as a birthday surprise trip with Alex Holly Gemma Andy Nicho Rosie. Super fun. Some of the highlights were going into surf the wave, Holly falling out and I hauled her back in. I fell out once and was hauled back in by Alex and Andy. We got T-boned when stuck in the surfing spot, Rosie tried to jump at the colliding raft so that she wouldn't go under but it looked like she was trying to push it singlehandedly.

10:25 Now I'm 30. Doesn't feel very different, but I have been having some interesting thoughts. (1) Most of the things I would like to change come down to mindfulness (health, screen time). This is something I should work on. (2) I enjoy my days off more when I do something or build something. I need to remember this for weekends.

10:29 Had the spontaneous idea to go for a swim at Austinmer and breaky at a cafe while there. Really nice way to spend the morning, especially since it wasn't very busy. Back is much better, I sometimes forget it which is a bit risky, but good signs. Thinking of replacing the corrugated sheet on the garage windows with a frosted wrap, should be low load on the back but let's be careful.

09:15 The day after hurting my back it's still very stiff but I'm able to move around lightly and did some chores. Going to have to take it pretty easy today which feels a bit boring. I might take a walk in the afternoon.

15:35 Just tweaked my back trying to transport mulch to the backyard. It's a bit frustrating, I'm now fully out of action and I'm not even 30 yet. This year apart from losing weight and hitting that 22:30 5k I'm going to add consistent core work into my goals.

14:06 Green bins were emptied just after lunch so it's back to tearing out the front yard. Super hard work in the hot sun. Struggling to find the enjoyment, but once it's cleared out the mulching will be satisfying.

16:20 Finished the front yard. Looking awesome. Now the tricky part: maintenance. Alex is looking to transplant the roses in winter when they go dormant and hopefully we can get some natives planted soon. Looking at the timestamps, it only took about 3 hours which means stuff like that is a feasible weekend job, no need to wait for holidays.

13:14 This morning I built some feet for my wooden balance beam using some scrap plywood glued to be 2x thickness. Cut out the shape and sanded it down nicely but when I tested it the beam was way too flexible. Abandoning the project and I'll just use the balance beam on the floor.

13:16 From now on no sugar for minimum 1 week; and then longer. I also want to set a running goal, starting tomorrow at an easy maintainable pace and going every day. No time limits or anything, just mandatory to get out of the door each day.

17:05 Just sitting out on the front porch after a game of uni disc golf. Pretty happy with the progress we've made on the front garden and looking forward to giving it another crack tomorrow once the bins are emptied. One more week off work as well. Very glad for that, I'm really enjoying the break.

08:35 Finished the balance board yesterday and it's fun. After a bit of use from me, the roommates and Coby it feels like the foam roller is getting flat spots so going to look for a denser roller today.

11:46 From YouTube video: rather than setting goals set a system for achieving the goal. A goal without a system of action is useless.

• My rating: ★★★★
• This movie had a lot of similarities with Knives Out. Very witty with an interesting mystery but it misses some of the novelty of Knives Out, so feels very much the same but with a different setting.

13:34 This morning was a lot of wood working. I built a frame for Alex's fabric print which is being stapled now. Then I started on the Indoboard (balance board). Looks and feels very nice but let's wait and see once the cabathane clear coating is finished. Excited to give it a go.

12:23 Spent the morning clearing the front garden. Feel quite good about that and thinking of heading for a swim. We've ordered 2.5m2 of leaf mulch from Dapto Sand and Gravel to use as a cover to prevent seeds sprouting.

17:37 Front garden is looking super good. Top layer and partial bottom layer is mulched, but we've run out of space in the green bins to continue. Will have to wait until Monday.

09:16 Today I have a micro-goal to not use any of the following: YouTube, Instagram, Reddit. I'll replace them with reading, microblogging or puzzling.

17:59 Just did a few bits and bobs today after waking up late. I feel like I could've done better with the day. Tomorrow I'd like to take on a big task, maybe a big push on the front garden to clean it up and prepare for new natives.

18:01 So far successful in avoiding apps from the morning. Going for some controlled use of YT while I wait for Jasmine Rice and going to read before bed.

09:09 Based on a YouTube video from yesterday I want to start replacing scrolling on the phone with micro-journaling. Just one or two sentences each. I will start with a Google Keep note and transfer over to my notes.org file in batches.

09:11 Watched the video from The Foot Collective on Functional Assessment (Kajabi app). Key insight is to get more floor time as it will naturally cause you to move position regularly, or as they call it, movement nutrition.

09:49 Dropped off the last of the wedding thank you cards at the post office and when I was there saw a puzzle for $10. Spontaneously bought it and after it's done maybe we can pass it on to Rosie.

This past weekend was our wedding, which was more than I could have hoped for.

We travelled to the Blue Mountains with Alex's mum, dropping her off at her AirBNB in Lithgow and then dropping of the car full of flowers and alcohol at the venue (our friends would also drop off lawn games, blankets, alcohol and other supplies later that day). We then drove back to Blackheath to arrive at our AirBNB in Blackheath (51 Hargrave Drive). The place was stunning. An awesome house with views over the golf course pond.

The Friday night we had a bunch of frisbee friends over and Rosie organised some wedding games. First was everyone had gotten us presents and we had to guess them by feel (and who they were from). Second was a pass the parcel with each layer being a couples question for us to answer, both for ourself and each other before comparing answers. Afterwards it was a busy evening of Alex and the girls making the bouquet and me and Rory doing the seating plan.

The morning was nice and quiet for us. We woke at about 7 and Alex drew us a bath, made me a surprise tea and had a little card waiting. As we sat in the bath and I read the card I teared up a bit, something that I didn't expect, but felt so nice. I didn't think I could cry, but at that moment I realised I might be crying for the ceremony.

We then drove into Blackheath to Hounslow cafe to grab Alex and coffee and ate some pastries that Celia had picked up for us from a shop in Sydney. We finalised the seating plan together and Alex edited our shared vows that I'd prepared previously. Alex then drove in for hair and makeup giving me some alone time at the house.

We were ready just before 1pm when our families started to arrive for the tea ceremony. We served Dragon Well tea to Alex's mum, my parents and Grandma and Nan. It was a really nice occasion and I'm so glad we did it for Alex. Alex's dad would be so proud of her.

From there I left for Secret Creek with the family which was a fun trip. I ot there with my bow tie in my pocket; the one job I had which would only be done at the last minute. The was a lot to do, but luckily the guests all helped so much. We set up the ceremony area thinking the start-stop rain from the morning should hold while others set out the seating arrangement name tags. I met the celebrant in person and signed some pre-ceremony documents. At about 2:45pm when the guests were meant to start coming up to the ceremony location I realised the ring was back at the reception area and I needed to pop on the bow tie, so headed back down. We gathered the guests, I grabbed the ring to give to Connor and had mum put on the tie. The walk up was nice, I got to greet some of the guests and at the top and had a nice greeting with Chris and Aidan.

Time was moving very fast and I was so aware of it. Not long after we were gathered at the ceremony Alex arrived and was driven up in the golf cart. People were seated or standing and I was by myself out front. I remember as Alex was walking down the aisle some of the guests were glancing back to see how I was reacting. Alex was so beautiful. She came down the aisle with her jacket on, stopped to pass it to her mum and we held hands. Kate, our celebrant, gave a really nice speech, telling our story. It was then time to say "I do" (happened so fast). We flipped a disc and I called the correct outcome, meaning I would be the first to read our shared vows.

As I read the first sentence my throat was stuck and I struggled to speak. I had to take many pauses and I could feel the emotion so strong. I didn't tear up, but I definitely lost my voice as I fell for Alex. She was able to speak the vows see eloquently and gracefully.

Kate then read the binding of the hands and we were married. We were showered with confetti and then had moments to take photos with family and friends before wandering back down to the reception area. Just at this time it started to sprinkle. The weather had held for us perfectly.

After a little while the photographer took us to Hassan's Point for photos. We were racing the weather and when we got to the lookout it was crazy. Strong wind gusts were being pushed up the cliff face and the rain was coming. Between photos we were putting the jacket on Alex to keep her warm. We even sheltered under a cave for a while, hiding from the rain. The photographer was loving the dramatic conditions and then the sun started beaming out from behind the clouds. Rain was flying upward from over the ledge and the light was stunning. It was so fun, what an adventure.

Back to the wedding and we were announced into the room before dinner. Dinner was incredible as we knew it would be and then it was time for speeches. Alex's mum was short and lovely; welcoming me to the family and passing on Foo's blessings. Dad gave a little bit of my story and talked about how they fell in love with Alex straight away. He was choked up as well throughout the whole speech. The final speech was Maddie, and she did a nice job. We sang happy birthday to Dad in front of the cake and then it was time for the first dance. We had a bunch of people join and it was actually one of the really nice moments. People then came back to eat the cake. We then went outside for some sparklers which tickled Alex's mum's fancy and seemed to create some really nice photos.

It was after this that time slowed to normal pace and we were able to enjoy talking with friends and family and spending some relaxing time together. At the end of the night we tried to give away as many flowers as we could and we left in the taxi back to Blackheath. Once we got home we had a nice little dance together and opened up our cards. We snuggled up in bed and had nice little sleep.

The next day we went to the venue to pick up the left over alcohol and supplies with my parent and said our goodbyes. We picked up Alex's mum and drove into Hounslow at Blackheath to have brunch with our friends and did a small walk at Hargrave's lookout. We then drove home to conclude the weekend.

The day was amazing, incredible and beautiful. I'm so grateful to my friends and family. Gemma MC'd the night and was so punny and great. She also was a great rock to lean on helping with random jobs and herding guests. Aidan and Chris were so good to talk to; even though we rarely see each other our friendship is so comfortable and nice. I loved seeing my family as always. Nan and Grandma looked so proud and it was so nice to have them there. Rosie was great and wise, giving us lots of good advice the evening before the wedding and arranging the games. The celebrant was amazing, and I'm so glad we chose her. James the photographer had such a nice energy and his enthusiasm was so fun. The photo sneak peak I've seen so far is incredible and we are obsessed.

Finally, I'm so grateful to Alex. She put in so much hard work to get the wedding to where it was and I'm so happy that she was rewarded with so much amazing luck and fortune on the day. She was so beautiful, glowing and graceful. I'm so lucky to have her and it's something I never want to forget. It was the perfect day and I like to think that our personalities shone through in how it all went. I'm looking forward to spending the rest of my life with her.

Reading through my previous entries I'm surprised that I've been talking about loosing weight since 2019. That's 4 years. It's somthing that I'm not proud of and is causing me to avoid certain activities (swimming, beach, hikes to waterfalls, etc).

We booked in our wedding for September 10 and I'm pretty focused on my body image going in so it's time to really start focusing on weight loss. I've already started building a habit of going to the gym and I want to add in bike riding and running. I might also try out the one meal a day idea to see how it goes. I know what to do, but need to build in habits.

Work is going well. With Aidan leaving I'll have to start taking on more responsibility, especially with management of the drafting team. I look forward to the challenge.

Volunteering to do jobs around the company seems to be serving me well. Two jobs with Aaron, one on blast loading and one on waffle slabs/helix SFRC are giving me the chance to learn new things from scratch. I've also done a presentation on blast loading, with an upcoming presentation on waffle slab design with CORD software.

I'm currently on my way home from a trip to Melbourne to meet and induct three new undergraduates who have just joined (two structural engineers and one drafty). Putting my hand up to do that was great. Even though I thought it was inconvenient I had a few cool experiences:

• Flight from Wollongong -> Essendon (super convenient)
• Visit Melbourne office ("The HUB"). Cool retrofitted office space in an old building next to Southern Cross station
• Stay in a 5 star hotel (Movenpick) with heated pool/spa and sauna

In hindsight I should have stayed an extra day since the 9am-10:30 flight got me stuck on an all stop train so the trip back is going to be from 7:30am to 1pm… Inducta doesn't work on the train (no internet dongle) so I haven't been able to do any work. Nice views though. I should come to northern suburbs of the gong more often (bike ride?)

This was a trip organised by Mandy. We had 10 people (Myself, Alex, Gemma, Andy, Holly, Matt, Fletch, Audi, Mandy, Tom) on a double hull catamaran for 10 days.

• Wednesday, 25^th May 2022 — Train to Sydney and fly to Proserpine airport arriving in the afternoon. We caught a private bus to Shute Harbour to our catamaran. We spent the night on the boat at the pier.
• Thursday, 26^th May 2022 — The morning was spent getting an induction from Gil on boat operation and local navigation. Without any experience driving within the group, I ended up as the official captain. We were taught how to drive under engines and also with the head sail out, but not the main sail. After lunch we dropped Gil off and headed for our first anchorage at Happy Bay (after the moores were taken at Sandy Bay). Happy Bay had an abandoned resort which we explored on the Friday morning. Gil's catch phrase: End Of Holidays
• Friday, 27^th May 2022 — From Happy Bay we sailed across to Sawmill Bay. First time using the headsail and getting comfortable with it. Sawmill Bay had a short walk which took us around to another beach.- Saturday, 28^th May 2022 — In the morning took the summit track up to Whitsunday Peak. Unparalleled views. Great place for an engagement. In the afternoon we did some snorkelling at False Nara and then moved on to Nara inlet for the night. No swimming there due to sharks, which we didn't get to see. Good calm location for the night.
• Sunday, 29^th May 2022 — The next day we took the track up to the Cairne while the girls visited another abandoned resort and found some coconuts. The walking track was deemed strenuous and bloke at the bottom told us we would perish. It wasn't too bad. Spent the night at Macaow Inlet.
• Monday, 30^th May 2022 — Drove to Hamilton Island (Hamo) and docked for the night. Afternoon we did a hike to Passage Peak. Picked up Mandy from her flight. Waiting for Tom to arrive on the Tuesday morning since he had Covid symptoms. In the afternoon we played some table tennis and had a swim in the resort pools.
• Tuesday, 31^th May 2022 — Sunrise at One Tree Hill, then the boys played putt putt. Did some sailing on the mini yaughts in the bay at Hamo and then Tom arrived. We set off and arrived at Whitehaven. Spent the afternoon at Whitehaven Beach.
• Wednesday, 1^st June 2022 — From Whitehave we crossed the channel to Chalkies for some snorkelling. Spent some time trawling for a moore. Snorkelling was good. In the afternoon we stopped at Hill Inlet for some awesome views. Stayed at Tongue Bay and saw heaps of turtles breaching for air.- Thursday, 2^nd June 2022 — Andy's birthday and a few hungover passengers. We drove to Butterfly Bay and did some kayaking around the reefs. Great spot right in the end of the inlet where we saw stingrays, turtles, and small reef sharks. Definite highlight.- Friday, 3^rd June 2022 — Travelled down to Sandy Beach via Langford Reef and Cockatoo Point. Snorkelling at Langford reef was awesome. Swum with a small turtle for a while and saw the stainless steel (Terry the) turtle. Cockatoo Point was even better. The reef there was amazing and was able to swim with an even larger turtle. Fish life was the best we'd seen here. At Sandy Beach (South Molle Island) we did an evening hike to Balancing Rock and abandoned (cyclone) resort. Saw a bunch of butterlies through the trees which was pretty magical. Lots of fish around the boat. Flying fish ran head first into boat.- Saturday, 4^th June 2022 — The last drive back to Shute Harbour only took 30 minutes or so and we dropped off the boat and caught a maxi taxi to Airly Beach. We spent a couple of hours hanging out at the lagoon and then taxied to our flights back home.

Some tips for setting up emacs on Windows:

On the 15th May 2020, I proposed to Alex. Here is the story:

Alex had worked from Mon-Thu during the week and had Friday off. I'd planned to go for a run an a swim in the previous days, so that morning we set off around 7:30am.

When we left, I had to make an excuse to head back in the house and move the ring from my hiding spot in it's box my textbook crate to the camping shelf for easy access when we got home.

We went for an easy jog, starting at North Beach, heading south around WIN stadium and back again. The morning was chilly, and at the end of the run Alex was not keen to get in the water. Probably for the best, since the water numbed the skin, but that was plan A.

One of our shared and cherrished memories was going for a run and swim at North Beach when we started dating, so I wanted to propose in the water. Oh well…

The ring was still fairly well hidden, so I went about plan B. I already had the ingredients to make a vegan thanksgiving roast (sweet potato mash, lentil mushroom stew and cranberry/apple sauce pastry) which we made for lunch. We then packed the finished product headed to Mt Keira lookout for a picnic.

Again, I had to head back to the house to get the ring, without making Alex suspicious. Luckily for me, I'd done a poo before we left, and she provided me with a great cover story asked "did you check that you flushed the toilet"? Dodged a bullet there since I didn't have a backup excuse ready…

I popped the ring into my pocket and had to hide the bulge while getting into the car, leaving it on my right side while I drove. When we reached the top I had to do some sneaky manouvering to take it out and put it below the back seat without her spotting it. The feeling was that I was acting weird, but she had no idea.

We ate and then I went back to the car to "put away the food/plates" and grab the ring. There were about three other groups of people at or around the lookout, but luckily after a few minutes of waiting they dissapeared and we ended up with the lookout to ourselves.

It was time. I had a few sentences ready, but when the time came I forgot it all. I mentioned the run/swim we had when we started dating and said I had a surprise planned. She started to cotton on and said are you proposing, where I replied yes. "Are you serious"? I was and said "I've know that I wanted to marry you for a while" and produced the ring, took a quick knee and asked the question. There was a yes and she began to cry. No time for ring placement, I hoped up for the hug. We hugged for a little and then did the business of putting on the ring.

It was a weird moment. Something I hadn't really ever imagined properly, but the feeling was nice. We were both very happy and took at least a few minutes to just take it in at the lookout.

We went from the lookout down to the 5 Islands Lookout and took a few photos at the rocks, before returning home. Things were back to normal, kind of. Nothing had changed, but Alex was now wearing a ring. It felt right.

On 2/02/2020 I attended Drew's home introduction, run by Graham and Sounboun - two Landmark leaders. The premise of the home introduction was to highlight the benefits for the $835 Landmark Forum course, run over three days (Fri-Sun) + Tuesday night, along with testimony from both Drew and Lui.

The benefits of the course seemed clear based on Drew and Lui's experiences which included:

• Clearer idea of what they want out of life and how to get it
• Improvements to family relationships
• Confidence to ask for what they want (4 hour week, different work conditions)

Although I like the sound of the course, the thing I dislike is the salesmanship displayed by the leaders. At the end of the session, both attempted to convince me to join the course which I was unsure about. The downsides were the cost and the amount of time required. Graham latched onto the fact that I was indecisive/cautious and said that is something that will hold me back. Although true to an extent, this is quite misleading. I felt under pressure and as though I was being tricked into the course.

My conclusion has been that I will not do the course. The reason being that I currently feel control over my life and think that the course seems better suited to someone who wants change. The other hesitation I have is that my impression is that those who do the course are pressured into sharing and bringing in others which seems slimy (caveat being that given the course is as good as it seems, it's understandable that you would want to share it with friends).

Perhaps doing the course would allow me to find the confidence to resist the pressure of having to share the course with others :P

This past week has had some good and bad aspects. It's been my fourth week working for Indesco in the Parramatta office.

Starting with some of the bad stuff, the commute (drive to Liverpool and train into Parra) has starting to get a little boring. Kinda been getting on my nerves a bit. I think it's partly the lack of good podcasts since I go through the good ones so quickly now. I enjoy reading Wheel of Time on the train, but feel like it's such a short time.

Next, I've been falling into some bad eating habits. With Woolies at Parra station, I've been getting snacks each evening to eat in the car. It's been making me feel bad and losing appetite for dinner which sucks. I've also felt lightheaded when doing physical activity (running, standing washing dishes). I went for two runs this week but was feeling pretty battered by the end of the week. I thought it was the extra exercise, but now I reckon it was the food. I want to start eating healthy. Perhaps replace my snack with a piece of fruit.

My relationship with Alex has been a bit strained, because there's pressure when we're together to make the most of time, but I always just want to rest or have quiet time. I should do something for her.

Some good stuff is that I showed my interpretation of the AS3600 integrity reo clause to Dave, which he picked up straight away. Previously they'd been using one bar counting towards the area required, but I showed that because the area is counted per column face, you can use one bar through the column as 2xA_bar. This has significantly (halved/more than halved) the amount of integrity reo used in the design. I think Dave and Mark Mobilia were impressed (maybe Mark moreso).

I've also hit a groove with the PT markups. Things have kinda clicked and I'm looking forward to really pumping through some slabs this week coming.

The first day of the fast wasn't that hard. Went for a 17km hike (Austimer to Stanwell) from 9am to 1pm. Was thinking about food and coming up with excuses for a snack on the drive home, but the cravings went away after half an hour or so. Went climbing from 4pm to 6pm and was surprised to not be exhausted or hungry afterward. Ate a big (1 3/4) serve of nachos for dinner. Also not hungry this morning.

Second day I barely had any cravings for food. This was a nice Sunday rest day and I didn't do much apart from a quick trip to Woolies for dinner. Had some tea mid afternoon. Had a large serving of donburri for dinner and a plant based meat pie that Alex had got for us to try. Looking forward to the rest of the week.

Starting from tomorrow (Saturday) I am going to begin only eating one meal per day. Just a challenge to try to bring into line my eating habits and hopefully loose some weight. I'm concerned how this will effect my gym and climbing, so I'll try to regularly update my progress/feelings here.

I decided that from now on, I need to target strength. I have noticed a slow sprinting speed lately, which is something to increase. At minimum, I need to be doing a pushup/situp/squat session every morning but a better result is to follow this plan set by Ryan Barbieri.

The plan includes:

• Single Leg "Speed Skater Jumps"
• Lateral Bounds
• Box Jumps
• Single Leg Step-Up Jumps
• Broad Jumps
• Single Leg Bounds (Skipping)
• High Catches From Kneeling
• Banded Lateral Twists
• Banded Star
• "Hard-Style" Plank
• Supine Bridge
• Med Ball Ab Twists (to failure)
• Single Leg Deadlifts
• Pistol Squats
• Ladder Drills
• Yoga / Stretching

Something that Willem said last night caught my attention; "It's not my fitness holding me back, it's the extra 40 pounds." Although I'm now feeling much fitter, and should continue to progress through running, the thing that will always prevent me from peak performance is carrying too much weight. I need the have both strength and light weight. This should be the quickest way to see large improvement.

To achieve this, I am going to focus on diet. No artificial sugars during the day any more. In addition, I would like to start experimenting with intermittent fasting as a way to help my body recover and stop food craving. Currently my body is always "on" trying to digest which uses up a lot of energy.

I don't think the I'm very happy with how 2018 panned out. Both my personal health and my work suffered. I think that this was down to my diet, which in turn had an effect on my motivation to work and exercise.

Eating badly while at work needs to stop. I am ashamed of it. This is the number 1 most important thing to focus on this next year.

Due to my lack of focus and motivation at work, I slipped into a number of bad habits. These included YouTube and Reddit. I have spent too much time on these websites and need to pair it down to start being more productive at work.

Towards the end of the year I began to form some good habits like yoga. Once I started getting in to this, it became very easy. I even looked forward to it. The benefits of this were mental as well as physical.

Some resolutions

• YouTube/Reddit only at lunch time (between 12pm-1pm). Use should be intentional.
• Go completely dairy free. This eliminates most of the bad foods that cause the problem.
• Start making some green smoothies to help with cravings.
• Set aside 30 minutes each day for yoga, a run, or other exercise.

Actions

• Find some software that block youtube/reddit
• Write out green smoothie ingredient list
