economy of scale and resource use. From the start, careful site plan- ning reduced the construction area by 620 square meters, making a smaller footprint in the sensitive river basin. The project team reduced overall land use for the bridge and civil infrastructure by 770 square meters, saving an estimated CNY 100,000 as a result. Bentley’s parametric modeling capabilities conserved engineering resources by reducing errors and rework. The team saved a total of 40 working days to date and construction coordination and inspection also took about 30 percent less time. Calculating material quantities with Bentley applications ensured that procurement was supplied with ac- curate amounts. Material consumption was reduced by 30 tons, saving a further CNY 100,000 on the project. The project’s successful progress onsite is mostly due to BIM-enabled construction management. To date, Long Jian Road & Bridge has achieved a number of critical objectives, including reducing mate- rial waste by 1 percent, using machinery and labor 15 times more efficiently, and limiting the cost of schedule deviations to under CNY Leaving a legacy often requires a lifelong fortitude of purpose and character that only the best among us can realize regardless of pursuit. In athletics, the pinnacle of success is that of an Olympic gold med- alist, a champion among all of mankind. In construction and design, legacies may not be as easily quantified, but once the truly spectacular is achieved it’s hard to overlook. When the new U.S. Olympic Mu- seum in Colorado Springs, Colo., opens to the public, it will unmistak- ably add to the legacies of design architects Diller Scofidio + Renfro (DS+R) and general contractor/construction manager GE Johnson Construction Company. “The incredible architecture we are delivering is challenging all of us to think beyond boundaries,” said GE Johnson Superintendent Tim Redfern, an industry veteran of more than 25 years. Redfern and GE Johnson Construction’s team are tasked with assembling a structure unlike any other ever built. DS+R’s design for the U.S. Olympic Museum takes its athletes as inspiration; the design idealizes athletic motion by organizing its pro- Leaving A Legacy Designers and construction manager push the envelope to deliver the U.S. Olympic Museum in Colorado Springs.

500,000. Upon completion, the project team will turn over the reality model-based asset management database to the owner for use in the operation and maintenance management phase. Long Jian Road & Bridge will continue to apply BIM advancements on a company-wide basis, defining standards, processes, and specifications for its future bridge projects. Chinese officials estimate that the Heilongjiang River Road Bridge will allow the transport of more than 3 million metric tons of cargo and 1.5 million passengers per year between China and Russia — 10 times more cargo and two times greater passenger traffic than currently. This will make an important contribution to China's One Belt and One Road Initiative, serving to revitalize northeastern China.

A full-scale exterior wall section was erected onsite to assist subcontractors developing a sequence for efficiently attaching the exterior skin to the structure.
