Why Coordinate Early
Build the Operational Plan Before Construction Starts
An office interior is not only walls and finishes. It must support people, security, technology, public access, privacy, maintenance, code compliance, and the opening schedule.
Review construction feasibility before signing a lease or buying a building.
Coordinate floor plans with furniture, equipment, power, data, security, and audiovisual requirements.
Identify long-lead materials, owner-furnished items, and landlord approvals early.
Plan phasing, after-hours work, shutdowns, temporary access, and move coordination.

The cost and schedule of an office renovation depend on the existing space, proposed layout, landlord criteria, mechanical and electrical capacity, technology requirements, finishes and whether the office remains occupied.
Bring the available plans, approximate square footage, lease or purchase status and target move-in date to the first review. Early scope decisions help identify design needs, utility questions, owner-furnished items, long-lead materials and sequencing before a final construction commitment is made.
Can GL Lewis review landlord plans or tenant-improvement requirements?
Yes. Share the landlord’s available plans, work letter, delivery conditions and approval requirements with the project team. These materials help identify what is included, what remains the tenant’s responsibility and which questions need to be resolved as the design, budget and construction scope are developed.
What is included in an office build-out?
An office build-out may include preconstruction review, selective demolition, partitions, doors, ceilings, flooring, millwork, reception and conference areas, restrooms, HVAC, electrical, plumbing, lighting, data and low-voltage coordination, accessibility, life-safety work, permitting, inspections, punch-list completion, and closeout. The final scope depends on the existing building, intended use, approved drawings, lease requirements, and local codes.
Can GL Lewis review a space before a lease or purchase is signed?
Yes. A pre-lease or pre-purchase construction review can identify visible existing-condition concerns, layout constraints, utility and building-system questions, accessibility items, likely drawing and permit requirements, schedule risks, and preliminary budget assumptions before a commitment is made.
Can an occupied office be renovated in phases?
Some occupied-office renovations can be phased. The plan must address protected access, temporary partitions, dust and noise control, life safety, utility interruptions, work hours, inspections, employee and public separation, and the approved construction documents.
Will signed and sealed drawings be required?
Many commercial office renovations require architectural or engineering documents. The building department, fire authority, existing conditions, occupancy, change of use, proposed layout, structural work, and mechanical, electrical, plumbing, fire-protection, and accessibility scope determine the final requirements.
Does design-build include permitting and construction coordination?
Design-build coordinates the owner, contractor, properly licensed architects and engineers, consultants, landlord or property manager, permit documents, budget, procurement, construction trades, inspections, and closeout through one organized delivery process.
Can technology, security, data, and audiovisual systems be coordinated?
Yes. The project team can coordinate pathways, power, low-voltage cabling, access control, cameras, conference-room audiovisual systems, wireless infrastructure, equipment locations, and vendor requirements when they are included in the approved scope and documents.
