12Build

What Stevin gets out of 12Build

12Build does one specific thing well: it puts out work packages, invites subcontractors and runs the request and bidding process between parties. For the tendering itself it is strong. What it does not do is watch what happens after the bid, and that is where the damage tends to occur. We see contractors stall on the handover from quote to execution: a subcontractor who does not respond, a bid that quietly excludes sealing work or a piece of scope, a price gap that only needs explaining later. 12Build collects the bids, but it does not lay the differences side by side and it does not tie them to your planning. Stevin reads along with the quotes and bids, through an export or a mail parser, and flags those differences before they punch a hole in your execution. The estimator sees the signal and decides, Stevin does the comparison work underneath.

What you pair it with

Choosing 12Build solves the request side, not the execution side. You keep the bidding process tidy, but the bridge to your project planning is something you have to organize yourself, because it is not in 12Build. The connection runs through an export or a mail parser, so the data comes out. The question is whether something is watching for a chosen bid that is missing scope or for a subcontractor who stays silent. Without that, you only discover the gap once the planning is already running and it is expensive to correct.

Common mistakes

• →Ticking off the tender process without watching the handover to execution, so the start stalls.
• →Missing scope differences between bids because no one lays them side by side.
• →Only noticing an exclusion in the quote once the work has already started.
• →Following up too late on an unresponsive subcontractor because no signal is set on it.
