In design-build delivery, the construction management at-risk (CMAR) firm’s ability to provide real-time services in an integrated and collaborative environment, is key to delivering the project on a reliable schedule and with a higher level of assurance of meeting the GMP during preconstruction services.
Throughout the North America’s design-build industry, there are a number of project delivery models that are successfully used for the design, construction and operation of water and water reclamation facilities.
It’s political season and the news is filled with commentary on liberals and conservatives and... progressives. So what exactly is so progressive about progressive design-build?
Well, it's no surprise, but the label for this valuable delivery method doesn’t have any political meaning! Instead, it’s all about evolving the design-build process to meet the needs of owners that could not use – or preferred not to use – fixed price design-build:
As 2015 came to close, the city of Houston, Texas, awarded a $900 million progressive design-build project to a joint venture of Water Design-Build Council member firms CDMSmith and CH2M for the design and construction of a 320-mgd water purification project. The project would expand the northeast plant from 80-mgd capacity in order to meet the demands for water by residents and businesses. Immediately signing the contract, the project teams began work in early 2016.
Quite a buzz in the water design-build industry erupted last week from an ENR opinion page report published on January 26 regarding findings from a team of university researchers in China and Australia. Their report, entitled Time and Cost Performance of Design-Build Projects, stated that over half of design-build projects analyzed ran over budget.
My work in 2016 started with support on a new program for a terrific client that is all about building critical infrastructure. Together, we’re figuring out the best delivery method to share risk, manage cost, drive innovation and get a shovel in the ground. It’s no surprise that alternative delivery is front and center in our thinking. And, oops, there I go again.
Early contractor involvement. (That’s good!) Constructability input with my engineer. (That’s even better!) A qualified contractor that knows the project before heading to the field. (That’s the best!)
Located in the City of St. Mary’s, Georgia, the Point Peter Wastewater Treatment Plant was consistently experiencing flows of 1.2 mgd and exceeded the capacity and 0.9 mgd discharge limits of its operating permit, primarily due to unanticipated development in the area.
During a recent education and discussion session with a state regulatory agency the following questions pertaining to the differences in design-build and CMAR delivery were addressed. The responses on these topics are provided below. Currently, most State SRF and DWRF programs require completion and approval of design prior to construction as well as a competitive bidding process.
