With traditional Design-Bid-Construct or Design-Construction Manager-Construct project delivery, the design team is contracted directly by the owner, ensuring direct planning and design coordination. However, in an effort to accelerate project delivery, or to single-source responsibility, many owners choose more non-traditional project-delivery methods, and parking structures are often delivered as a Design-Build project (contractor-led project) or as a Public-Private-Partnership (typically a developer-led project). In these scenarios, the degree of owner participation will vary, but in most cases the contractor or development partner is responsible for planning, design, and construction. In some cases, the project’s success may only be measured by initial cost, schedule, and the number of new parking spaces.

Where the owner relinquishes some level of design and construction authority, but maintains full long-term maintenance and operations responsibilities, WGI recommends retaining a third party to represent the owner’s interests, and to confirm that the design appropriately considers function (entry/exit and access/revenue control, technology, vehicular/pedestrian circulation, and parking layout), user comfort and safety, wayfinding, structural system impact on performance, mechanical/electrical systems, operations, and long-term performance with respect to maintenance, future repairs, and service life.

Ideally, third-party parking design expertise is introduced during the planning phase, with the development of bridging, or basis-of-design documents that set minimum standards for the parking structure design and construction. However, owner’s representation services can be engaged at any point during the project’s planning, design, or even construction phase. As the owner’s representative, WGI will represent the owner’s interests, providing design review and oversight, construction administration review, and general assistance related to achieving a functionally efficient and durable parking structure. Important considerations include:
Project Definition – The owner enters into an agreement with the developer or the Design-Build contractor that defines contractual terms. This agreement also should include details related to the parking structure design criteria, establishing the aesthetics, function, and durability requirements. As the owner’s representative, WGI provides guidance regarding these key design and construction elements. Our assistance may include:
