LSST Summit Facility general contractor, Besalco, has officially taken possession of the Cerro Pachon site in order to begin the construction effort. Going forward, the LSST site now is an active construction site with all of the consequent safety rules and restrictions in effect. In particular, access to the site by project personnel now must be pre-approved by Besalco. Besalco began work in January 2015, mobilizing personnel and equipment and establishing offices and a warehouse on the summit. They are working with their subcontractor Rocterra to remove the final 20,000 cubic meters of material. Excavation for the telescope pier foundation and construction of the road to the telescope main platform are nearing completion. The platform for the calibration telescope is complete.
