The San Francisco International Airport’s Runway 1-19 improvement project was the largest airfield construction project undertaken at SFO in the last 50 years. The start of construction occurred on February 3, 2014, and was originally scheduled to be completed on October 28, 2014; however, DeSilva Gates Construction successfully completed the project one month ahead of schedule on September 24, 2014.
While the overall project duration was completed in only seven and a half months, over $90,000,000 of construction and the entire $50,000,00 of owner-supplied materials were completed in a three-month span. During this three-month time period the two runways, 1L/19R and 1R/19L, were closed on May 17 and then reopened for full departure on August 10, one month ahead of the original schedule. The re-opening of these two runways marked the completion of SFO’s Runway Safety Area project, and all allowed for all four runways at SFO to be operational.
“Because of your efforts, we were able to complete the Runway Safety Area project, more than 20 months in advance of the Congressional mandate of December 31, 2015. The $226M project was completed under budget at an anticipated cost of $223M. The completion of the Phase II RSA projects signifies a major milestone accomplished by the Airport and your team is a big reason for our success. Your efforts are greatly appreciated.” – John Martin, Director San Francisco International Airport.
The Project had no recordable injuries or lost time accidents after 145,000 man-hours worked, was under budget, exceeded the stringent FAA contract quality requirements, achieved completion with no unresolved issues or claims, and received many awards including the International Partnering Institute’s highest award, the Partnered Project of the Year Award.
