Pre-Construction

Pre-construction that makes design decisions defensible.

Site evaluation, conceptual estimating, value engineering, and procurement strategy. Brought in early enough to actually influence the design, and the proforma, before the choices are locked in.

Serving Manhattan, the outer boroughs, Long Island, Westchester, and Northern New Jersey.

What we cover

What our pre-construction team delivers

Site & building evaluation

Existing conditions assessment, structural and MEP capacity review, freight and access analysis, and building rules study. We tell you what you're really buying into.

Conceptual estimating

Test-fit-grade budgets, SD/DD/CD estimates, and ROM pricing to match the design phase. Every estimate is tied to current NYC trade-level subcontractor input, not stale published indices.

Value engineering

Cost-driver analysis with options that preserve design intent. We tell you what the choice actually costs and what you give up, not just where to cut.

Constructability review

Drawings reviewed by the people who would build them. We catch the conflicts, the missing details, and the unbuildable assumptions before bid day.

Long-lead procurement

AHU, switchgear, generators, custom millwork, stone. We identify long-lead items in DD, lock prices early, and protect the schedule from supply chain surprises.

Bid packaging & strategy

Trade-level package definition, qualified bidder lists, scope leveling, and bid recommendation memos that lay the reasoning out so owners can actually make the decision.

How we work

How we run every project

1

1. We listen

Call (212) 947-6441 or email mahenegan@henegan.com. We sit down with you, your architect, and your real estate team to understand the program, the schedule, and the constraints we have to work inside.

2

2. We pre-construct

Conceptual estimates, value engineering, site evaluation, long-lead identification. We get the budget and schedule honest before the GMP is signed, so the surprises are small and the answer is yes.

3

3. We build

Buy out the trades, run the BIM coordination, sequence the work, keep the site safe, hit the milestones. Weekly OAC meetings, real schedule updates, and a superintendent on site every day.

4. We close out

Punch list, commissioning, sign-offs, O&M manuals, warranties, and the documentation your facilities team needs to actually run the space. We don't disappear after substantial completion.

Pricing

How pre-construction is priced

Pre-construction fees typically run as a fixed lump sum scaled to the program, from $15K for a small interior test-fit through $150K+ for a base-building or large mission critical study. Most owners credit the pre-con fee against the GMP at award.

What affects the price

  • Program size and complexity
  • Number of design phases we estimate (SD/DD/CD)
  • Depth of VE, constructability, and trade input required
  • Procurement strategy and long-lead study scope
  • Whether owner credit-at-award applies

When the project proceeds to construction, our pre-construction fee is typically credited against the construction contract, so you only pay the value once.

FAQ

Common questions

Ideally during programming, or as early in schematic design as the team allows. The cost of changing the design is lowest in SD, highest in CDs, and a real problem after bid. The earlier we are at the table, the more the budget and schedule align with what the owner actually wants.

We produce ROM (program-level), SD, DD, and CD estimates as the design matures. ROM is typically +/- 20%, SD +/- 15%, DD +/- 10%, CD +/- 5%. Each estimate identifies the gap between the design and the budget, the assumptions in play, and the risk that needs to be carried.

Not by cutting the obvious things first. We look at cost drivers, MEP density, finish complexity, schedule compression, building rules, and bring options that preserve the design intent while moving the cost. Every VE item has a hard number, an impact, and a recommendation.

When the design is at a level that supports it, yes, we offer a GMP at the end of pre-construction with a defined buyout strategy. For earlier-stage projects we'll commit to a budget number with a clear path to converting it to GMP once the design supports the conversion.

Bring us in before the design locks.

Pre-construction fees credit against the construction contract, so the budget you get is the budget you build.
