Travilah Grove represents a very difficult piece of construction work, one of the toughest that Gaines and Company has faced in this decade. Nestled on a cozy twelve acre lot in Rockville, Travilah Grove has more problems than a typical job. To begin with, as is common in Rockville, this job site has loads of hard, stubborn rock. Complicating that issue is the existence of two WSSC owned waterlines made of very rare, fragile pre-stressed concrete, PCCP. One is 60” in diameter and the other 36” in diameter. Both of these lines traverse the site from one end to the other. Breaking either one of these pipe lines would send a torrent of water down the street and affect service to tens of thousands of people. These lines sometimes rupture and leak on their own. Because of this, WSSC frowns on blasting on this site, preferring to see it removed by hydraulic breakers. This works occasionally, but sometimes the rock cannot be removed without blasting. In this case, long and persistent negotiations took place before a reasonable game plan could be adopted. It was up to Gaines and Company to implement the plan and get the job assembled on time and on budget.
This site of 117 lots contains 45,000 cubic yards of site cut to fill and another 25,000 cubic yards of import. There is 4,750 feet of 8” and 4” sanitary sewer. Water lines include 3,150 feet of ductile iron pipe. Also included in the development package are 8,000 feet of curb and 9,200 square yards of paving. Much of these lines are contained in rock areas and must be shot carefully to avoid damage to the afore mentioned water lines. Gaines will also lay a new DIP pipeline to replace the 30” PCCP and minimize potential disruption from blasting and other construction activity.
