CASE STUDY Project Summary Organization: City of Santa Barbara Construction Manager: MNS Engineers, Inc. MNS Engineers Uses ProjectWise EADOC to Manage Replacement of Historic Bridge ® Design Firm: Bengal Engineering Engineering Firm Keeps Track of the Challenging, Three-stage Project with a Web-based Project Management System General Contractor: Lash Construction Inc Historic Architectural Character Location: Santa Barbara, California, United States Project Objective: Replace a historic bridge alongside one of the busiest roads in Santa Barbara, California, while preserving the structure’s architectural character. Product Used: ProjectWise EADOC Fast Facts • The City of Santa Barbara needed to reconstruct the bridge’s upstream and downstream areas as part of the Lower Mission Creek Flood Control Project. • MNS had to maintain street access throughout the project lifecycle due to the city’s tourist-based economy and large numbers of daily visitors. ROI • Project managers improved transparency and team collaboration with EADOC’s automated audit trail of all document and communication activity. • The Cabrillo Bridge team saved time by linking workﬂow documents—such as RFIs and change orders—to other items such as locations and construction drawings. • EADOC’s centralized database provided 24/7 access to manage project documents, which saved time by eliminating the need to manually manage project communications. The City of Santa Barbara needed to replace a structurally deﬁcient, historic bridge along one of its busiest roads while maintaining its architectural character. Originally built in 1913—with additional reconstruction work performed in 1927 and 1977—the Cabrillo Boulevard Bridge spans Mission Creek, which drains into the Paciﬁc Ocean next to Santa Barbara’s iconic Stearn’s Wharf. The challenge was reconstructing areas upstream and downstream as part of the Lower Mission Creek Flood Control Project in a busy location. This meant the structural and architectural scope of the project had to be carefully managed by the construction manager, MNS Engineers, Inc. The bridge replacement project is being executed in three stages. It includes demolishing the existing bridge and adjacent channel walls and constructing a precast girder bridge structure, pedestrian sidewalks, concrete-lined creek and channel walls, embankments, and tidal habitat. The project scope includes transition walls, two abutments, a bent, barriers, a wider sidewalk, and a pedestrian bridge. To manage this multifaceted project, MNS implemented Bentley’s ProjectWise EADOC cloud-based construction management software for contract administration and document control, and to coordinate the entire project team and stakeholders. side of Cabrillo Boulevard will be erected during the third stage to accommodate nearly 6,000 pedestrians daily. When complete, the new bridge will be 9 feet longer than the original and will meet new earthquake and structural safety standards. The project will also improve creek water ﬂow and create a habitat for steelhead trout, tidewater goby, and other marine life. The new 9-foot-wide sidewalks will be twice the size of the old ones, and ofﬁcials expect the entire project to be complete by 2017. A Tight Squeeze On the surface, the project looks like it could be a fairly straightforward bridge replacement, but its complexity lies in its location—the main thoroughfare through a town with a signiﬁcant, tourist-based economy. The need to maintain street access to the popular tourist area prohibited the complete closure of the roadway and created the need for careful coordination of team members, equipment, temporary pedestrian walkways, and restricted trafﬁc. “It would have been a lot easier if we could have just closed the roadway, but in order to keep the area’s tourist-based businesses open we needed to maintain access for the large number of daily visitors,” explained MNS Vice President of Construction Management Gregory Chelini. Not a Second to Lose Stage one and two of Another complicating factor construction, which included the team had to overcome was preliminary sitework and the seasonal restriction on rebuilding the mountain side certain construction activities. of the bridge, have been Due to environmental The Cabrillo Bridge construction site is adjacent to lower completed. Stage three will considerations regarding include the replacement of the State Street and the entrance to Stearn’s Wharf, a popular indigenous ﬁsh and marine beach side of the bridge, while tourist attraction. life, the project’s permitting keeping the mountain side open includes strict guidelines that only allow construction work to car trafﬁc and reopening a wider sidewalk on the mountain within the waterway to occur from June through Oct
