Design/Build Overview

One of the most efficient and cost-effective methods of construction is the Design/Build concept. Design/Build is effective because it promotes efficiency by allowing the contractor and engineers to work together, using innovative means to find solutions to many technical problems before the construction process begins. It unifies the responsibility for the project in one source-the Design/Build team.

Addison Smith provides comprehensive mechanical design services on either a single source design/build format or as a design/assist partner. Design/assist can be as simple as design review for constructability or completion of detailed design documents. Addison Smith can provide a guaranteed maximum price which provides strong incentives for completing projects on time and under budget. Other advantages are:

Accelerated project delivery

Actions such as estimating, value engineering and construction can proceed during the design phase.

Improved Team Concept

A partnership is created within the team. No adversarial relationships exist. The team works closely with the builder to assure constructability and the most cost effective construction process.

Guaranteed maximum price early in the project

A firm price can be established to assure the owner's budget is not compromised. Compare this to plan and spec where the owner is subject to price increases.

Single source of responsibility

The designer and builder are on the same team, they assume responsibility for all phases. The owner does not have to look to multiple sources of responsibility.


Design/Build is a concept that has gained popularity in recent years because it promotes efficiency by avoiding cost overruns and delays which would ultimately cost the design/builder, not the owner.

Addison Smith has executed Design/Build projects from several thousand dollars to $2.5M
