The first phase of the contract for the Central Puget Sound Regional Transit Authority (Sound Transit) covers pre-construction services and is worth approximately US$1m (£655,000) to Hill over a one-year period. The second phase covers the construction period and, if exercised by Sound Transit, is likely to be worth US$21m (£13.8m) to Hill over a subsequent four-year period.
The work is for the E360 segment, the 1.8-mile terminal stretch of the East Link Light Rail extension running from East Bellevue to the main Microsoft campus in Redmond. The alignment includes aerial guideway, at-grade and retained cut sections, and features two new stations, two pedestrian bridges and a 300-vehicle car park. The estimated civil construction cost of the project, which is expected to be completed in late 2019, is approximately US$200m (£131m) to US$250m (£164m).
During the pre-construction, Hill will provide support to Sound Transit through the procurement of the design-build contractor, including reviewing and modifying the request for proposals and design-build contract and reviewing the preliminary designs of the shortlisted teams.
During the construction phase, Hill will continue to provide review services during the development of the design and expand services to include project management, estimating, scheduling, quality control, inspection, safety and commissioning.
"The impact of the East Link Extension is enormous, as it will provide a reliable connection from the Eastside's biggest residential and commercial centres to downtown Seattle, Sea-Tac Airport and the University of Washington," said Michael Smith, senior vice president and western regional manager for Hill's project management group.
