This is certainly one of the more complex projects that Gaines and Co. has tackled in many years. EYA Construction has purchased a complex of Montgomery County agencies including the county bus terminal and the Bureau of Parks and Recreation. The plan to convert this property into a very high-end residential townhouse community complete with parks and a retail complex for the buyer.
The fronting road, Crabbs Branch Way, had to be widened and improved to suit the new project. Throughout the whole project including entrances and adjoining roads were a vast array of infrastructure, most of which was not useable for the new project but had to be kept in operation for the existing agencies, some of which had moved next door. A great deal of innovative thinking went into various “work arounds.” The assembled team included construction manager Jansen Land, Vika Engineering and Gaines and Company.
The first two phases began with a sizable temporary pond with about a 21,000 CY cut. Gaines also had to cut and regrade 19,000CY on Crabbs Branch Way. In that cut were Pepco, Washington Gas, Verizon fiber and telephone lines and Comcast cable lines. So, it was not “blow and go,” instead more like “hunt and peck!” Gaines’ excavating foreman, Matt Hobbs did yeomen’s work minimizing damages to existing lines. Gaines will also grade the adjoining apartment project for Bozzuto Homes.
The sanitary sewer on the “A” portion of the project totaled 960 LF of 6”, 8”, 12” and 15” SDR. Those lines were quite deep, mostly over 20’ in depth. There were also 6 each 48” manholes and 4 each 60” manholes. Again, most were 20’ or deeper. Gaines’ foreman, Mike Tarr, did an awesome job on this tricky phase which involved traffic control, rerouting of existing sewer flows and frequently required night work and all the headaches that night work brings.
The “B” phase of this project includes 2,000 LF of 4” and 8” C-900 PVC sewer pipe. Here the cuts average a mere 14’-18’. There are nine more manholes on this part of the project which extended sewer along and across Crabbs Branch Road. Traffic controls were set up to keep traffic away from the excavation.
The storm drain on the job is quite large, and it, too mixes with the surrounding existing utilities. There are a combined 600’ of 60” RCCP and 58”x 91” ERCP. Other RCCP totals 3,000 LF of pipe sized 15”- 42”. There is also 190’ of 48” HDPE, 54’ of 66” CMP and 90’ of 36” CMP. Structures for the storm drain include nine 48” manholes, 2 deep 60” manholes and one 16’ deep 72” manhole. There are also 19 A-10 inlets, up to 14’ deep. There is a 60” A-15 inlet 10’ in depth. Also to be installed are 19 E inlets, a CO6 and WR. There are 4 junction boxes including a 10’ x 10’ x 18’ deep! As noted everything is quite deep and intertwined closely with existing utilities.
The water line also threads back and forth across Crabbs Branch Lane necessitating night time crossings. It includes 2,230 LF of 16” DIP, 2,215 LF of 10” DIP and 30 LF of 8” and 6” DIP. Also to be installed are fifteen 8”-14” valves and 17 fire hydrants with valves.
Roadway work involves extensive traffic control and detours handled by MT Laney. The road work includes substantial demolition of Crabbs Branch Lane, 9,520 LF of curb and gutter, 3,905 SF of concrete median and 12,310 SF of sidewalks. The actual asphalt work consists of 17,600 SY of full depth asphalt paving, 2,415 SY of overlay and 3,200 SY of 8’ wide pathway.
