Pre-construction is everything a general contractor does before building starts: reviewing the drawings for gaps and conflicts, pricing the work with real subcontractor proposals, value engineering where it makes sense, and building a schedule the team can actually hold. It's the cheapest phase of a project to fix problems in, because a problem caught on paper costs a conversation, while the same problem caught in the field costs demolition, rework, and time. At PBS, pre-construction is the first of our three core services, and it's where good projects are made or lost.
Drawings review: finding the problems before they're built
No set of drawings is perfect. Architectural, mechanical, electrical, and plumbing sheets are produced by different people on different timelines, and they don't always agree. A thorough pre-construction review walks the documents looking for conflicts — a duct and a beam fighting for the same space, a finish called out in one place and contradicted in another, details that can't be built as drawn. Every conflict found at this stage becomes an RFI to the architect instead of a stoppage in the field.
Real pricing means real subcontractor proposals
There are two ways to price a project: plug in allowances and hope, or put the drawings in front of qualified subcontractors and get committed numbers. We do the second. Soliciting and leveling subcontractor proposals takes longer than throwing out a square-foot guess, but it produces a budget the owner can trust and exposes scope gaps early — when one bidder includes something the others excluded, that's a flag worth chasing down before contracts are signed.
Value engineering, done before it's desperate
Value engineering belongs in pre-construction, not in a panic after bids come in high. When there's time, the GC, architect, and owner can weigh real alternatives: a different wall assembly that performs the same, an equivalent fixture line with shorter lead times, a ceiling approach that saves labor without changing the look. When VE happens late, it tends to turn into cutting things the owner actually wanted. We've written separately about doing value engineering without cheapening the project — the short version is that timing is most of the battle.
Scheduling around reality, not optimism
A pre-construction schedule worth the paper accounts for permit timelines in the actual jurisdiction, lead times on the specific equipment and materials specified, building rules about noise and freight access, and the sequence dependencies between trades. Long-lead items deserve special attention — identifying them early and releasing them for order at the right moment is one of the most concrete ways pre-construction protects the end date.
Logistics, permits, and the unglamorous groundwork
Pre-construction also covers the practical setup that owners rarely see: confirming permit and filing requirements, coordinating with building management on insurance and access rules, planning protection of adjacent spaces, and lining up inspections. On occupied buildings and dense urban sites — most of PBS's work across our project portfolio — this groundwork is the difference between a smooth first month and a stalled one.
What the owner gets out of it
At the end of pre-construction, an owner should hold a leveled budget backed by subcontractor commitments, a schedule with real dates, a drawings set with major conflicts resolved, and a clear scope of who builds what. That package is what makes the construction phase boring, in the best sense of the word. Since 2009, across 82+ completed projects, the jobs that went smoothest were consistently the ones where pre-construction was taken seriously.
Frequently asked questions
How long does pre-construction take?
It scales with project complexity — a straightforward interior fit-out needs less time than a project with long-lead equipment, landmark approvals, or significant infrastructure work. The honest answer comes after a first look at the drawings, which is exactly what an initial consultation is for.
Does pre-construction cost extra?
Some GCs price it as a separate service, others fold it into their fee structure; what matters more than the line item is whether the work actually gets done. Skipping pre-construction doesn't avoid the cost — it just moves it into change orders later, usually at a worse rate.
Can pre-construction start before drawings are finished?
Yes, and it often should. A GC engaged during design can flag constructability and cost issues while the architect can still adjust the documents cheaply, which is far better than discovering them after the set is finalized.
