Construction That Keeps Your Business Open

The biggest risk in an office renovation is lost productivity. We reduce that risk with scheduling built around your operations.

Phased construction. We divide the project into phases so parts of your office stay open and usable while other areas are under construction. Staff move between zones as each phase is completed.

After-hours and weekend work. Noisy or disruptive work can be scheduled for evenings, overnights and weekends, so your team isn't working next to demolition.

Clean, contained work areas. We use dust barriers, floor protection and daily cleanup so occupied areas stay professional.

Coordination with IT and equipment vendors. We work with your technology and equipment providers so phones, network and workstations are ready when your team moves back in.

Working With Landlords and Building Management

Commercial buildings in New York have their own rules for contractors. Your landlord or property manager will usually require approved drawings, certificates of insurance, and work that follows the building's hours, freight elevator schedule and trade requirements. When permits are required, we coordinate with your architect or engineer so filings are handled correctly.

We handle these requirements every day, which keeps your project moving and your relationship with your landlord in good shape.

Our Office Renovation Process

  1. Site visit and planning. We walk your space, learn how your team works and identify what must stay operational during construction.
  2. Proposal and schedule. You receive an itemized proposal and a phased schedule that shows what happens, when and where.
  3. Approvals and permits. We provide COIs, coordinate with your landlord and support permit filings with your design team.
  4. Construction. Work proceeds by phase, with regular updates and a single point of contact.
  5. Move-in and closeout. We complete punch lists, coordinate final inspections and hand over a finished, ready-to-use workspace.
