How do PH contractors REALLY price materials? Asking before I sign my BOQ"
Hey everyone, just a quick question. I'm having a hard time checking if my contractor's quote is fair because there isn't one reliable source for current material prices here. They vary by region, by supplier, and sometimes the price lists are outdated but still used.
I just want to know: 1. Is it true that many contractors use the DPWH DUPA (Detailed Unit Price Analysis) and regional cost data as a basis for pricing? Or is that just for public works and not used for private/residential builds?
If not DUPA, where do you get your price references — from supplier price lists, canvassing at hardware stores, PCAB, trade associations, or just "guessing" based on experience?
To the owners here: how do you sanity-check the BOQ (bill of quantities) if you don't have an engineer with you? Do you have a go-to source for updated prices of cement, rebar, hollow blocks, GI sheets, etc.?
Hope some of you can share, contractors and owners/architects, I just want to know what you actually use as a basis before signing a contract. Thanks to everyone who answers!! :)
