March 23, 2018 - After three years of construction work on Cerro Pachón, general contractor Besalco Construcciones achieved substantial completion of the LSST Summit Facility on February 28, 2018. On that date, the building keys were officially turned over to LSST Construction Inspector Jaime Seriche and LSST Site Manager Eduardo Serrano. Although 20-30 Besalco workers will remain on-site for a few more weeks, addressing punch list tasks, LSST now has authority over the occupation of the facility and the site work schedule. Current activity in the building includes IT equipment installation, furnishing of offices, and post-construction projects for various LSST subsystems.
According to Telescope & Site Architect Jeff Barr, It's worth noting that despite the inevitable challenges, delays, and changes that occurred during the three years of construction, "the contract between LSST and Besalco is concluding on successful terms." Jeff anticipates that the punch list items will be complete and final acceptance of the building will occur in April.
