This is an exciting new project for Gaines and Company in a new area for a new client. It is part of a major rehab of the old Montgomery County General Services property. The project will eventually hold over four hundred houses even though this initial phase will include mostly infrastructure and only 31 lots.
The project will begin with sediment controls, including 3,400 LF of super silt fence and 3,900 LF of standard silt fence. A major basin will be installed by Gaines. It will include about 22,000 CY of excavation. There will also be 18,500 CY of cut along Crabbs Branch Way as it is reconfigured for the new project.
The sewer on the project is very deep and challenging and must be coordinated with traffic control on Crabbs Branch Way. It includes 2,400 LF of 8” C-900 and SDR 35, 840 LF of 12” SDR 35, and 330 LF of 15” SDR 35. The cuts on the sewer range from 10’-24’ in depth with 600 feet being deeper than 20 foot. This project also includes 15 sanitary manholes up to 22’ in depth. There will be 1,100 LF of 4” C-900 for the lot connections. There will also be some live sewer pump-arounds required.
The storm drain phase contains a lot of large diameter pipe and also many big structures. There is 2,000 LF of 15”-21” RCCP, 800 LF of 24”-36” RCCP, 660 LF of 36”-48” RCCP and HDPE, 310 LF of 60-66”RCP and 350 LF of 58”x91” ERCP. There will be 13 storm manholes, of which 9 have 40” diameter, 2 have 60” diameter and 2 will have a 72” diameter. There will be 37 A inlets, 19 E inlets, a WR, an A-10 and 49-5’ CO6 inlets. There is also one 10×10 and one 7×7 junction box. That’s a lot of storm drain!
The water system features 2,230 LF of 16” DIP, 2,215 LF of 10” DIP and 270 LF of 8” DIP. The water system also has to be weaved in and out of the new and old paved areas in Crabbs Branch Way. There are also 2-14” gate valves, 8-10” gate valves, 16 fire hydrants and 16- 6” valves. There will also be 31- 1 ½” meter settings for the houses.
The road phase will involve substantial sequencing and maintenance of traffic. Major demolition of existing Shady Grove and Crabbs Branch Way will also be a part of this scope of work.
Paving for Crabbs Branch, Shady Grove and Metro property total 20,500 SY of asphalt. Concrete work includes 10,320 LF of curb and gutter, 3,900 LF of medium and major retaining walls. There are also two long asphalt paths with pedestrian bridges. That will be another fast track project. Gaines is ready to hit the ground running and not slow up until the finish line is reached!
