here's my comment on tile pricing

2nd contractor.... price seems abit cheap
average RM10.35/sqft for 2x2 and 2x1 tiles......price sounds very good
but you need to check what tiles they supply

in my post in the tiles thread.....i'm using good quality porcelain tiles and homogenous type

average price for good quality tiles and workmanship is between rm20 to rm25 p sqft
that's what i have been comparing and gathered through out the research

concrete top price normally rm150 per foot run....meaning 1ft x 2ft = rm150 excluding tiling
and you have include the 3feet vertical support as part of the calculation too

so assuming your 17 foot run straight without L bend....you may need 3 vertical support....thats roughly 26feet total.....x rm150 = 3900

sink and tap.....budget about rm600 for very basic bowl and tap

2k plus for melamine door and drawers

sound very reasonable...again....please do ask for sample material before deciding

just for budgetting...since i'm also renovating my house now

grills: basic design wrought iron with 10mm solid tube wrought iron bars, powder coated, fully welded joints...rm20 per sqft
example: 8feet x 5feet window = 40sqft x rm20 = rm800. if need to remove existing grills....add another rm2 per sqft
the price is negotiable usually if you have more than 4 sets of windows
usually they oso cover the emergency escape panel......

i think if mild steel with powder coat....maybe rm15 to rm14 per sqft
if really basic basic...mayber rm10 kua....

wiring:
rm100 per light point inclusive of downlight fixtures (8"), local copper cable wiring, Schneider Vivace light switch, labour for opening the downlight hole, fixing of the light and patch works for conceal cabling

rm95 per 13A power point, includes schneider power plugs, local 16awg copper cables

RM250 for oven control point, 20A switch, concealed power face plate for back of oven

RM160 for ceiling fan, include hook, wiring, installation of fan, wiring and switch

RM200 for water heater and aircon per point, with 20A switch

DB box, MRCB, MCBs 3 phase about rm2000 depending brand and number of MCBs

piping is subjective
my piping costs rm18k
stainless steel incoming main pipes

3 x water tanks 300 gallon (my house frequent no water)
2 x grundfos water pump
2 x joven 25 liter water heater tank

autogate......this is the recent quote from Delux

RM340 per foot run for full aluminum power coated 5.5' height gate
RM310 per foot run for wrought iron frame, aluminum bars, galvanized and powder coated

swing arm autogate from Delux is RM1700...i think it comes with backup battery built in

option to have small single walk in gate add rm250

price excludes armor cable wiring

Well, if you keep on looking on brand only, sure people will slaughter you. Hacking cost is rm0.50-1.
Again, you need to do more survey.
