CMAA Interviews Kathleen Linehan, P.E. About Recently Renovated Washington Monument

Alpha Corporation’s work on the two-year Washington Monument project focused on upgrades of the mechanical and technological components of the elevator to provide increased reliability and service life; construction of a geothermal heating and cooling system for the new visitor screening facility; and construction of the new visitor screening center.

The environmentally sustainable geothermal system, also known as the ground source heat pump, is a highly efficient renewable energy technology. The new glass-covered security screening center enables an efficient screening process for visitors to move through the facility effectively.
