Process

From first conversation to keys in hand — and beyond

A deliberate four-phase process. Owners stay close throughout. Surprises during construction are rare because the work happens upstream, in design + pre-construction.

Phase 1 — Discover

Months 1–2

  1. 1
    Step 1
    First conversation
    30-minute call. Tell us about the project. We tell you whether we think it’s a fit. If yes, we schedule a site visit.
  2. 2
    Step 2
    Site visit
    We walk the property. Read the site — light, water, neighbor sightlines, mature trees. Often this changes the brief.
  3. 3
    Step 3
    One-page memo
    We write a short memo describing what we’d propose. Scope, approximate budget, schedule, design approach. No commitments yet.
  4. 4
    Step 4
    Mutual go / no-go
    If we both want to keep going, we sign a pre-construction agreement. If not, we part as friends. Many of our future projects come from clients we declined the first time around.
Phase 2 — Design

Months 3–8

  1. 1
    Step 1
    Schematic design
    Architect develops massing, floor plans, and site organization. Two formal owner reviews. Usually 6–10 weeks.
  2. 2
    Step 2
    Design development
    Material palette, elevations, mechanical systems, structural strategy. Builder team feeds in constructability + cost throughout. 8–12 weeks.
  3. 3
    Step 3
    Construction documents
    Full drawings + specs ready for permitting + bidding. Final value-engineering pass. 6–8 weeks.
  4. 4
    Step 4
    Permitting
    Building, zoning, conservation (where applicable), historic review. Hartwell handles the permitting process; some projects need 1–4 months.
Phase 3 — Pre-construction

Month 9

  1. 1
    Step 1
    Final cost estimate
    GMP (guaranteed maximum price) finalized. Aligned with the design and your budget. Surprises happen here, not during construction.
  2. 2
    Step 2
    Schedule lock
    Detailed schedule with milestones. Subs committed, materials ordered, deliveries scheduled.
  3. 3
    Step 3
    Subcontractor + craft team
    We work with the same 12–14 specialty trades project after project. Carpenters, masons, plasterers, finish carpenters, mechanical, electrical, plumbing — known quantities.
  4. 4
    Step 4
    Owner orientation
    Final walkthrough of plans + materials before construction begins. Communication cadence + decision-making protocols agreed.
Phase 4 — Build

Months 10–22

  1. 1
    Step 1
    Site mobilization
    Site organization, protection of mature trees + landscape, temporary services, access routes. Site looks like a craftsperson’s site, not a chaotic construction zone.
  2. 2
    Step 2
    Daily supervision
    Hartwell project manager on-site daily. No subcontractor self-supervision. Daily progress photos uploaded to client portal.
  3. 3
    Step 3
    Owner walkthroughs every 2 weeks
    Scheduled walkthroughs let you see the work + ask questions. Decisions get made on-site, not in email chains.
  4. 4
    Step 4
    Punch list + close
    Comprehensive punch list completed before move-in. Final walkthrough. Warranty packet delivered. Stewardship period begins.
What stays consistent

Through every phase

Owner stays close
We don’t hand the project off to a junior PM. Lead architect + lead builder are the same people from first call to final punch.
Same craft team
We bring the same specialty trades to every project. They know our standards. They know each other. Quality compounds.
Daily site supervision
Hartwell employees on-site every day. Subcontractors don’t self-supervise. Quality + schedule both stay tight because someone is watching.
Honest communication
Bad news early is better than bad news late. If something is slipping, you hear it from us before you ask. We don’t hide problems.
Documentation
Daily progress photos, weekly written updates, monthly financial reports. Client portal lets you see everything in real time.
Stewardship beyond move-in
30-day, 6-month, 1-year, and indefinite check-ins. We’ll come back for adjustments long after the warranty ends.
Process questions

What people ask

  • We use GMP (guaranteed maximum price) contracts after design is complete. Pre-construction services are billed hourly during the design phase. Cost-plus is available for projects where the scope is genuinely undefined; rare.
