Critical Steps in Managing the Cost of Designing and Constructing Office Space

Tenants who fail to rigorously assess design and construction costs before signing a lease expose themselves to budget overruns and difficult decisions under schedule pressure. These decisions are often reactive and suboptimal. This dynamic is the result of poor planning and is highly avoidable.

A great tenant advisor adds value in many ways, but one of the most important is assembling the right team at the right time. For tenants pursuing long-term leases with custom-built space, that team must include both an architect and a general contractor.

Experienced brokers can provide an early cost framework to help establish a realistic budget before a space is selected or designed. This is an essential first step, but it is only a starting point.

Architects and designers are creative by nature. Their initial designs often exceed budget. That is not a flaw, it is part of the process. The next step is cost engineering, where the design team and contractor work together to align the vision with the budget while preserving key elements of the design. This is a disciplined and highly collaborative exercise.

Having the right team is not enough. They must be engaged in a way that aligns with the tenant’s objectives. In most cases, this means bringing on a general contractor early under a “GC and Fee” structure. Under this approach, the contractor is retained for a fixed fee covering general conditions and overhead, rather than being selected later through a lump sum bid.

Early engagement creates accountability and improves cost visibility. It also reduces the risk of change orders, which are a primary driver of budget overruns. The goal is to enter the final bidding phase with a fully developed set of construction drawings and a well-vetted cost.

At that stage, the general contractor runs a competitive bid process across all sub-trades. With this level of preparation, tenants significantly increase the likelihood of delivering their space on budget and on schedule.
