4 PROJECT PROFILEH oward T. Ennis School,Georgetown, DEAll-Span, , DEFABRICATORPROJECTThe obvious solution to theseretrofit challenges was a slopedroof with a built-in mechanicalspace. Although the traditionalapproach would have been to utilizea structural post and purlin system,the architect wanted to ensure suffi-cient area for the new air handling units, as well as minimize the number of pene-trations in the existing roof membrane. All-Span, brought in to helpdesign an optimal re-roof system to provide an attractive, low maintenance slopedroof while minimizing installation time and classroom minimize the number of trusses (and the installation time required), wedesigned two mono trusses spaced 6 feet on center to cover the 82' x 305' mainschool building.

5 A short pony wall was built up along the exterior bearing wallsand a row of stub posts spaced 6' were installed along the center of the exist-ing roof. With only one center bearing, the number of roof penetrations wasreduced from several hundred for a traditional post and purlin system to only 50 or so for the Ultra-Span installation andmaintenance access for thenew rooftop units was easilyaccomplished by designingand building a large mechan-ical room into the trussescovering those areas wherethe units would be the assistance of the precise layout, connection, and engineered bracing dia-grams (an Ultra-Span system exclusive!) that All-Spanprovided, the TRUSS installerwas able to retrofit the Ennis school in just two weeks!

6 And, by working evenings andweekends, no class time was lost (great news for the parents and educators, badnews for the kids!) The Howard T. Ennis re-roof is a perfect example of how we can helpcompress construction cycles andreduce total cost through the speedand efficiency of pre-engineered, factory-built Ultra-Span TRUSS systems are most commonlyused in new construction, this project is an outstandingexample of how Ultra-Span can be incorporated in aretrofit Howard T. Ennis School was like so many other educational facilities builtduring the 1960 s. The one-story brick structure was designed with a flat hot tarand gravel roof system. As with most such roofs of this vintage, water leakage and seepage had become a major problem, creating a costly, repetitive mainte-nance nightmare.
