Riddle: Owners have a number of considerations when deciding how parking structure projects are delivered. A general contractor that can self-perform the concrete on a parking structure almost always gives the client an advantage in terms of more quality control, cost savings, and efficient and quicker delivery. Structure type is one of the most important design components of a parking structure and will impact construction and long-term maintenance costs, as well as site security and aesthetic appeal.

Cast-in-place concrete structures are a viable option when working with a self-performing contractor. They are generally less expensive and require less long-term maintenance because they are more durable. They also provide owners with some aesthetic flexibility, as well the ability to enhance the end-user's public safety security through more opportunities to have an open frame.

In terms of delivery, the design-build delivery model is an effective solution for the vast majority of parking structure projects because the contractor and designer are one contractual entity — allowing for a more collaborative approach. This guarantees certainty on cost early in the design process, minimizes change orders, and results in a much faster project delivery process. The result is improved decision-making for the entire team and cost certainty for the owner.

Riddle: McCarthy has built more than 200 parking structures all over the country. In Northern California, we have a dedicated parking structure business unit, employing a skilled self-performing workforce that understands critical labor components such as formwork, efficiency of repetition and quality control in the installation of materials. Self-performing the concrete helps to achieve efficiencies throughout the construction process, such as cost savings, scheduling ease and quality gains on parking structure projects. There are very few general contractors in Northern California that do this work and it's a huge benefit to clients.
