NEW YORK, July 31, 2014 /PRNewswire/ -- New research from McGraw Hill Construction ( http://www.construction.com) published in its Project Delivery Systems SmartMarket Report reveals that while owners, architects and contractors in the buildings sector all agree that the choice of a delivery system on a project impacts project cost, schedule and the potential for overall client satisfaction, perspectives on which of the three established delivery systems can best deliver these and other benefits often vary widely by player.
Established delivery systems include design-bid-build systems, in which owners hold a separate contract with the design firm and contractor on a project; design-build systems, in which one entity delivers both design and construction to the owner; and construction management at risk (CM-at-risk) systems, in which the owner contracts with a construction manager during design who works collaboratively with the design team in the final design stages and offers the owner a guaranteed price for the final completion of the project.
Research in the Project Delivery Systems SmartMarket Report indicates that choice of a delivery system can have potentially powerful implications for the ability of the project to be delivered satisfactorily, on schedule and on budget:
- Client Satisfaction: The highest percentage of owners who are highly satisfied with their projects are also those using the CM-at-risk delivery system (60%). However, architects are nearly evenly split in their opinion of the best delivery system to improve client satisfaction between design-bid-build, design-build and CM-at-risk. On the other hand, the highest percentage of contractors by a wide margin (43%) regards design-build as the best system for improving owner satisfaction.
- Cost: The highest percentage of owners reporting projects coming in under budget (33%) are those using a CM-at-risk delivery system. However, the highest percentage of architects (38%) believe design-bid-build is the best delivery system for reducing construction costs, and the highest percentage of contractors (38%) find that design-build reduces costs most effectively.
- Schedule: There is a consensus among owners, architects and contractors that design-build has the best impact on schedule of the three established delivery systems included in the study, a rare moment of agreement in otherwise highly diverse results.
- 23% of owners, 42% of architects and 30% of contractors expect to see decreases in the use of design-bid-build;
- 50% of owners and contractors expect CM-at-risk to increase;
- 63% of owners and 68% of contractors expect increases in design-build.
- Owners' top drivers of specific delivery systems: Maximizing the budget drives all three delivery systems, and it is more important than reducing project cost as a driver for the design-bid-build and design-build delivery systems. Improved quality on projects is another top driver for future use of CM-at-risk.
- Architects' and Contractors' top drivers: Reducing project cost nearly always ranks above maximizing the value of work put in place for the budget as top drivers for design-bid-build and design-build, representing a large disconnect from the owners' opinion. More architects also report reducing construction schedule as a key driver, and more contractors report that concerns about risk/liability are a key driver for CM-at-risk.
