    You can get your contractor or architect to register you under the RRT (Routine Rostered Testing) scheme as people required to visit site (owners are included). This is still paid for by the government so its FREE :)

    Thanks! I tried to get my builder’s help but he not being very helpful. Hence checking to see if the rest have better experience. Did your builder include you in routine testing? Mine says it’s only for people in his company? 
     

    not sure why 3cube has to be so angst in his reply. nobody is suggesting to bypass, we can all share our positive experience. No need to play righteous cop here.

    i just standby a 32A isolator at my attic level so that in case need/want to install solar panel, this cable can be used to carry the electricity down to my DB. of cos this isolator may not be able to be used for solar panel but the wiring inside can be used. it's just a matter of changing the isolator to one which is suitable for solar panels.

    Thanks snoozee! The 32A isolator should be within reach? And out of weather elements right?

    the RC trench is under PUB's purview. once the trench is completed, photos would need to be taken and submitted to PUB. an officer from PUB would also go down on site to do the inspection. After the inspection and PUB approves of the trench, the trench would be backfilled with sand (again with photos taken at height intervals for record purpose) and finally filled covered with precast concrete slabs. the precast concrete slabs are removable so that PUB can remove them as and when they need to do repairs or maintenance to the sewer line within your property. but then i would think most owners would just cement over the RC trench after obtaining approval.

    That’s very clear thanks! Sorry another question so cement screed and tiling on top of the pre-cast slabs are perfectly fine right? If PUB ever needs to work on it, we will have to hack?

    even for a inter terrace, a sewer line running through the width of the site would be at least 6m long. judging from the photo, it's definitely more than 2m deep. your builder is taking a big calculated risk by just using the plywood sheets to retain the soil. by right any excavation more than 1.5m deep would require ERSS to be designed by a PE and submissions to BCA for approval. and the retaining structure is certainly not constructed just by wooden planks and plywood.

    the 10K quoted amount is most likely just for show as the builder can recover the cost elsewhere from his contract to you.

    Thanks Snoozee for the insight, don’t wanna get anyone in trouble... Just to clarify, but the RC trench will be inspected by BCA to ensure it’s properly done up right?

    you are lucky that your sewer line is very near the surface hence the low cost of $10k. my sewer line is almost 3m deep and it cost me almost 6 digits to build the RC trench. bulk of the cost actually went into the design and construction of the ERSS to provide stability to the ground during the construction of the RC trench

    ? yes I think I read many expensive experience on RC trench and we were quite scared. Our builder assured (put in contract) that it will not be more than $10k, maybe cos ours is inter-terrace and smaller. I think it was around 2m deep?

    I extended back 1st & 2nd floor 5.9m x 6.7m (need to reinforce RC trench is another $10k job) new roof, upgrade electrical to 3 phase 60A, hack and relay new tiles, relocate toilet and kitchen so changed plumbings, was quoted between $450k to $750k, in the end we chose the $450k guy cos our colleague used him before. So far so good, need approximately 8-10 months for A&A. 3 months in Reno now! 
     

    I would say just go and talk to a few builders and see their projects, design and build firms are cheaper than architect if you just want not so much design. Extend 1m behind if no RC trench maybe cheaper? 2nd storey if want to extend 1m, not sure if it can be a balcony or light weight structure, need to check with the rest of the seniors here ?

    I remember an architect told me before that if they retain enough pillars and walls then it will be considered reconstruction? Maybe can check with them how much need to be retain. Also can email BCA or PUB to ask if you need to clarify on your site’s specific situation. We made the mistake of listening to so many contradicting stories from Builders and architects, in the end asking the officials can be quite simple. But I Guess don’t over ask like it’s a counter service.

    Thanks Petetherock for the thread! And Snoozee for the detailed explanation. We have checked with the contractor, according to him single phase 100A would not require inspection, only 3 phase 100A, I suppose it’s as per what Snoozee mentioned for 45KVA supply. 
     

    The idea of planning for future electric car charging at home porch is tempting haha. Since gonna phase out ICE cars by 2040 right. Getting a few quotations for solar now, probably will do a small one sufficient for now and maybe upsize 10 years later. Still considering....

    Hi Snoozee & petetherock thank you guys for the invaluable advice once again!

    I did not know that single phase 100 amps require annual inspection. What’s the inspection cost like? (Tried to google but can’t seem to find the info) will definitely talk to the contractor about changing to 3 phase 63amp. And maybe add the infrastructure for solar grid connection. Any ideas on whether solar make sense here? 
    Read that typical lifespan is around 25 years, and the warm weather here degrades the PV cells faster. Sell back to grid if you’re SP user and if you’re open market user there a difference in calculating. And there’s a Intermittency Pricing Mechanism? Sounds suspiciously like additional tax for using solar.

    Hi guys, wondering if anyone can share their experience on laying city gas piping for their landed house? I read a post in 2017 that installation alone would be $4700 + how far they have to pay the piping. Has anyone done it here? Would like to know how much it came up to be. Would you choose to pay for city gas piping or just pay for monthly gas cylinders? 
     

    Or would you use the money for laying city gas piping to pay for installation of solar panels instead? Then maybe just get induction hob? We are re-wiring to single phase 100amps. Is this enough for induction hob?

    Hi guys, thanks the replies.. we requested for $3.50 Homogenous tiles throughout the house and entry level doors and windows, not including carpentry, mainly want to concentrate on structure works now. Will definitely consider more quotes. So far there are 3 quotations that seems more doable under $480K. But they are design and build firms. Wondering how to Ensure that quality is what they promise? How did you guy approach this?

    Hi guys~ how have your sourcing of Builders been? Please PM me, maybe we can share info. I have a few quotations so far. 
     

    I want to do back extension for 1st & 2nd floor of an inter terrace. Change roof, new tiles, rewire and new plumbing pipes. Been quoted an average of $600k which is quite a bit off our Budget. Would like to hear about your experiences!

    Just to chip in a bit. I have used the same builder as MetalTab. Any forummer that is interested to get a second opinion on this builder, feel free to PM me.  Doing my part to contribute back to this forum. 

    Hi guys, could you share with me your Builders contacts too? We are looking to extend our inter terrace and do a whole renovation, upgrading electrics, piping a and changing roof.. Thanks!
