InService Firm coordinates commercial tenant improvements that turn an existing leased space into a place ready for business. Based in Edmond, Oklahoma, we serve projects nationwide and connect scope development, drawings, permit coordination, construction and HVAC through one point of contact.

Define the work inside your leased space

A tenant improvement project starts with the condition of the premises and the use you intend. An unfinished shell, an occupied space and a previous tenant’s fit-out each require a different review. Floor plans, utility capacity, equipment needs, access and existing building systems influence what can be reused and what needs to change.

Before setting a construction budget, identify the work assigned to the landlord and the tenant, the available drawings and any building rules that affect construction access or working hours. Our preconstruction planning services connect that information to a scope that can be priced and scheduled.

Coordinate the layout with existing building systems

New partitions, ceilings, equipment and finishes need to fit the existing structure and services. Layout decisions can affect electrical connections, plumbing interfaces, heating, cooling and ventilation. The project team reviews drawings and site information together to identify gaps before ordering materials or closing construction areas.

We connect commercial HVAC coordination with the wider tenant build-out so mechanical work and other trades can follow the agreed construction sequence. When restaurant premises are involved, kitchen layouts, equipment and ventilation need a coordinated review; see our restaurant construction services.

Plan approvals, access and construction milestones

Permit submissions and required reviews depend on the project location, intended use and scope of the changes. We coordinate the supporting drawings and review responses with the appropriate project professionals and local authorities. Approval timing belongs in the project schedule alongside material lead times and site access.

For a building with other occupants, construction planning should address shared access, deliveries and the interfaces between the work area and existing operations. The agreed scope and site arrangements guide trade scheduling and inspection milestones.

Manage changes through handover

Existing conditions can raise questions once work begins. Proposed changes should be documented and reviewed for their cost and schedule effects before additional work proceeds. Our commercial general contracting brings the construction trades, deliveries and site decisions together.

Closeout connects punch-list work, required inspections and the information included in the agreed handover scope. The owner’s move-in preparations and any approvals needed for the intended use should be considered when planning the date the space will open for business.

Discuss your commercial tenant improvement

Share the project city and state, approximate space size, business use, lease or landlord information, available drawings and target opening date. Describe whether the space is vacant, unfinished or currently occupied, and identify the changes you already know you need.

Discuss a tenant improvement project or submit a referral. We can start with an early layout idea or existing construction plans and identify the next planning step.

Tenant improvement questions

Can an existing commercial space be reused?

A review of its condition, systems and intended use helps determine which elements can remain and which require changes. Available drawings and a clear proposed layout help establish that scope.

What determines the tenant build-out budget?

The condition of the premises, extent of the changes, equipment and finish choices, building-system work and unresolved design decisions all affect the estimate. Allowances and exclusions should be identified before construction commitments.
