Senior Preconstruction and Estimating Manager

The Gowanus Group is a New York-based design-build firm specializing in healthcare renovations and hospitality projects. With a team of more than 30 professionals and an extensive network of subcontractors, we bring together design, construction expertise, and hands‑on execution to deliver complex projects.

Our work spans hospitality development and healthcare environments, where thoughtful planning, disciplined budgeting, and strong collaboration are essential to successful project delivery.

We are looking for a Senior Preconstruction & Estimating Manager to lead the preconstruction process across our growing portfolio of hospitality and healthcare projects.

Reporting directly to the CEO, you will own projects from early concept and design development through final pricing, procurement, and handoff to construction operations. You will work closely with owners, architects, engineers, and subcontractors to develop accurate budgets, identify risks, and ensure projects are positioned for successful execution.

Your first major assignment will be a ground‑up hotel development, making direct experience estimating new construction and hospitality projects essential.

This is a hands‑on leadership role for someone who combines deep technical estimating expertise with strong commercial judgment. We are looking for someone who can independently own complex estimates, challenge assumptions, and bring structure and accountability to the preconstruction process.

• Build strong project partnerships. Work directly with clients, design teams, subcontractors, and internal operations to establish clear expectations around project costs, schedules, and deliverables.
• Support planning and execution. Collaborate with operations teams to develop master schedules, phasing strategies, and construction logistics plans.
• Strengthen estimating capabilities. Build and maintain cost benchmarks, improve estimating standards, expand subcontractor relationships, and mentor preconstruction team members.
• Ensure seamless project handoffs. Deliver complete, reliable budgets, schedules, scope documentation, and procurement records to construction operations.

• 8+ years of experience in preconstruction or estimating with a general contractor, construction manager, or design‑build firm.
• Proven ground‑up construction experience
  , including independently leading estimates from early concept through GMP or final pricing.
• Direct hospitality estimating experience
  , ideally involving ground‑up hotel construction, with lifestyle or luxury hotel projects particularly relevant.
• Strong technical understanding of structural, building envelope, MEP, and interior construction systems.
