i see here only get posted on bad contractors details ? i am planning for renovation so far consult 2 contractors and 1 designer. only got quotation from the designer which is not in details.
all 3 contractors i never seen their work, 2 picked from internet and 1 ppl recommendation
So my main purpose is renovation & little designing
-re-roofing and waterproofing
-concrete leaking waterproofing
-wall crack fixing
-toilets modification and water proofing
-plumbing
-electric rewiring and lighting
-plaster ceiling
-tiling
-window framing
-interior designing rooms, study rooms, living hall, dining, kitchen
Already consulted 3 contractors visited my premise and waiting for quotation from them. All 3 Chinese ( 2 of them contractors 1 is designer who has contractor). 1 already sent quotation just for roofing, the designer fella probably he could have consulted his own contractor.
Current roofing style (timber crossing with tiles) already 20 years old and many leakage issues also from concrete. So i planned to completely change the design and interested on metal/steel truss roofing system with metal roofing/ PU FOAM roofing which good for heat insulation and noise reduction. If i am using tiles on the steel truss then planning to cover with aluminium bubble foil.
Since i am changing the roof design, which is different from original. I think i need engineer drawing for DBKL approval. I also find out some companies offering this metal truss roofing services, also have engineering services to design the truss based on roofing design..
OK, so the designer who gave me quotation just for ROOFING work about 48k total. Not so in detail. No break down on roofing part
For Supply & construct metal roofing & steel support at roof top is 40k, so i throw him some question how he quoted the price, based on what type of roofing, what about design drawing of architect / engineer for approval. i even send him some pics on the type of roofs. Pending his reply.
Other 2 contractors still no quotation yet. I am looking for trustworthy and quality workmanship.
i have sent samples below to all those contractors at least to give them some ideas what i am looking for.Lots of Indonesian and Vietnamese freelance contractors but not very comfortable to handover them the job, fear of quality and cheating.Any brothers, would like to recommend me trustworthy and quality workmanship contractors most welcomed
also heard about the movement of metal truss or metal roofing due to thermal expansion/contraction, how do we address that issue. stretch and shrink of metal truss/ metal roofing due to hot and cold weather. how bad the noise is ? any solution for this.
i am wondering who will be installing this truss, normal contractor workers or the steel supplier's workers.
