Cornell University’s Klarman Hall project has posted a schedule for the next six months, while LeChase Construction and Welliver have completed more roofing work throughout the month of march. The southern wing’s roof looks nearly complete, along with most of the southern portion of the main building, as the previous slate and metal roofing has been completely removed, re-surfaced with synthetic underlayment, and replaced with new slate and metal.
Underpinnings for Goldwin Smith and Klarman’s foundation have begun installation as indicated on the schedule. They’re typically used to support an existing foundation by digging underneath section by section, and backfilling the trench with concrete to provide additional support and stabilization. The crews will be digging all along Klarman’s future footprint, and along East Avenue. The future weight of Klarman Hall would likely have an adverse affect on existing footings as the new building settles into the soil, so the work will ensure that the existing foundations are safe and sufficient. For certain situations (especially repairing unlevel settling), a building’s foundation is actually jacked up with hydraulics to fix the level.
