Longwood Main Fountain Garden The Main Fountain Garden Revitalization at Longwood Gardens is the largest renovation project in the garden s history. It consists of the massive renovation and restoration of the five acre, central, open-air fountain including 9,000 cubic yards of concrete, 1,400 linear feet of tunnels, and five miles of fountain pipes. Keast & Hood was retained as the structural engineer of record under the design team which was led by Beyer Blinder Belle. Structural scope includes design for a variety of elements to support the updated pumping and lighting infrastructure while maintaining historic garden features. Highlights include design for two new concrete pump rooms. The first is the Upper Canal Pump Room, a below grade single story, 3,000 SF, reinforced concrete structure and consists of Upper Canal controls and water storage tank for the Upper Canals. The second is the Rectangular Basin Pump Room, a two-story, 45,000 SF reinforced concrete structure that extends two stories below grade. The Rectangular Basin Pump Room houses all the pumps and equipment associated with the Rectangular Basin and the Lower Canal as well as two water storage tanks to avoid freezing and prolong function into colder seasons. The new structure was constructed adjacent to the historic pumphouse and as such required underpinning of the historic structure which is now used as a museum. A unique challenge of the design was that the lowest level of the Rectangular Bain Pump Room had to be designed to resist high hydrostatic pressure due to existing ground water conditions. The project site is comprised of five acres and over 50 percent of the work is below grade. The project was complex in that it required the moving of a massive amount of earth and touched every aspect of Longwood Gardens crown jewel, the Main Fountain Garden. The high profile project involved considerations for the insertion of technologically advanced new infrastructure while maintaining sensitive, historic elements of the original structure. A new architectural feature of the revitalized Main Fountain Garden is the Grotto, comprised of reinforced concrete with a stone veneer. The reinforced concrete shell of the Grotto is suspended from the concrete beams of the Rectangular Basin Pump Room s roof structure. Another design element includes the new concrete feature stair and elevator which transports garden visitors to the Main Fountain Garden s terrace level at the west end of the site. Also incorporated into the new design are historic retaining walls which engineers assisted in preserving and restoring. Portions of the historic walls were removed to provide access to the new Rectangular Basin Pump Room building site and were replaced with reinforced concrete, replicating the historic design. There are 1400 linear feet of new concrete tunnels below the Main Fountain Garden site which improve accessibility to the pipes, electrical wiring, fountains and other important equipment necessary to keep the fountains running. The innovative design brings Longwood s infrastructure in the 21 st century and makes for improved ease of maintenance and service. The new tunnels required coordination between the precast tunnels and the cast-in-place canals directly above. The Main Fountain Garden at Longwood Gardens provides visitors with a display experience unlike anywhere else in the world thanks to the enduring vision of Longwood and the undertaking of the restoration project. The complex project required frequent coordination between the designer, engineers, and stone restoration contractor - resulting in one of the most widely anticipated Grand re-openings of the year.
