Design-build projects are not new, but this method of delivery has been traditionally considered for large projects and not for municipal transportation infrastructure work, such as roadway repaving, reconstruction, and other upgrades. Depending on the project goal, reconfiguring your design-bid-build project to a design-build project can provide real advantages, such as a single contract and point of contact for both designing and constructing the project. In addition, the contract includes all services and products to be delivered by the team—creating closer, more streamlined coordination between the designer and the builder.
Another significant advantage is that costs can be determined at an earlier stage and with greater accuracy, allowing the owner to have a guaranteed maximum price for the finished project before the project even starts. Further, this type of project generally provides significant scheduling benefits.
In the Kansas City region, interest in design-build delivery is spreading within the public sector. Olsson has been involved in four very different projects, all using this method of delivery.
Sheridan Drive Design-Build
Fort Leavenworth, Kansas
Olsson and McAnany Construction, Inc. teamed to provide design-build services for reconstructing over two miles of Sheridan Drive. Sheridan Drive was deteriorating and needed to be rehabilitated. The directorate of Public Works for Fort Leavenworth desired a prompt and cost-effective solution. Working together, Olsson and McAnany were able to perform a quick, value engineering analysis and generated ideas for the Fort that would reduce costs while maintaining Kansas Department of Transportation specifications and criteria. The end result was a roadway that met serviceability and design life requirements while minimizing the impact on the surrounding environment. Almost the entire, existing roadway was recycled in some form or another. Part of it was hauled to Fort Leavenworth’s levy and used as a new aggregate roadway, and the other part was reused in the new asphalt mix.
The project was split into three phases. Phase II and Phase III designs were completed while McAnany reconstructed Phase I. By allowing the contractor to get involved early in the project, the end result was a reduced project schedule. Construction was completed in the summer of 2012, and Fort Leavenworth officials were very happy with the results from the design-build team experience.
"‘I expect to have cooperative exchanges of ideas with our design-build partners, and Olsson didn’t disappoint.”
- Pat McAnany, McAnany Construction Company
“I appreciate the hard work and thinking outside-the-box that your engineers have done to make this a really nice road for all involved.”
- Larry McAnany, McAnany Construction Company
Brookview Gardens Neighborhood Improvements
The City of Liberty wanted to improve its Brookview Gardens subdivision. However, the city didn’t have the funds to fix everything on its “wish list,” which included rehabilitating and upgrading the road, replacing the waterline, and improving drainage. To maximize its available funds, the city selected a design-build method to tackle the multiple, needed improvements within the neighborhood. After conducting a qualifications-based selection, the city’s chosen contractor, Emery Sapp & Sons, Inc., along with the selected engineer, Olsson Associates, came together to evaluate the city’s needs. Together, the firms developed preliminary, cost-effective options that would maximize the improvements, stretch the city’s money as far as possible, and set the stage for future improvements. With this method, Liberty was also able to get early cost forecasts for both the design costs and the construction costs. Construction will start in the spring of 2013.
Santa Fe Streetscape
151st & Black Bob Intersection Improvements
The City of Olathe was under an extremely tight time frame to complete intersection improvements at 151st Street and Black Bob Road and decided to use the design-build method as a way to accelerate the schedule. As part of this project, the needs of a new grocery store opening in the fall of 2013 had to be balanced with the needs of nearby existing and future business owners and citizens’ traffic demands and safety concerns. With Olsson as the designer and O’Donnell and Sons Construction as the contractor, the team addressed scheduling considerations up front, leading to more efficient implementation.
Time is also saved because design and construction activities can proceed concurrently. In addition, because team members are working side-by-side, the team can successfully complete the project in a timely manner through its ability to identify, modify, and implement needed changes along the way. The project is scheduled to be completed in the fall of 2013.
Design-build has proven to be a successful project delivery method for implementing municipal transportation projects. In our examples, accelerated project delivery, cost, or both were major factors in the decision to use design-build.
In deciding to take the design-build path, our teams have found one element to be vital to project success: communication. It is important to encourage partners to get together early in the process to discuss common objectives and establish procedures and schedules for formal communication. It’s imperative to foster an environment that encourages all team members to communicate freely and to informally share ideas and work through challenges, keeping all team members in the communication loop.
