Phase 2a: Construction of Utility and Road Infrastructure
Scott & Ritter Inc. of Bowling Green, KY, the General Contractors for the project, subcontracted GWC Enterprise, (Gary Wayne Cifford) of Hodgenville, KY to start installing on June 20, 2013, the utilities for the water, sewer and electric lines. About 100 feet of 8" main line was installed to have access to city water. The blue line will run from the main water line to the house and the green line is for the sewer line.
Two underground electrical systems have been installed to support the electrical transformers.
As of July 14, 2013, Scott & Ritter Inc. has prepared a gravel bed in preparation for the permeable on-street parking lane for the first three houses that Habitat for Humanity anticipates on starting to build in 2014. The on-street parking lane will be covered with permeable blocks to allow water filtration and prevent water runoff.
Mick-Murf Construction Inc. of Bowling Green has the curb poured and Scott & Ritter of Bowling Green, has the fine aggregate laid for the installation of the Permeable Articulating Concrete Blocks. "The PaveDrain System is a Permeable Articulating Concrete Block/Mat (P-ACB/M) that creates a performance pavement that integrates the patented arched reservoir to maximize onsite stormwater capacity during extreme storm events" (Pavedrain, 2013). This information and more information about the P-ACB/M system can be found at http://www.pavedrain.com.
Miller construction of Bowling Green, KY, is contracted by the project's sub-contractor, Mick-Murf Construction Inc., to install the Permeable Articulating Concrete Blocks, made by Lee Brick and Block of Bowling Green, KY.
On August 8, 2013, Jeremy Dant, Representative of PaveDrain (in the green shirt), supervised and helped install the P-ACB/M product at the Durbin Estate Project. Jeremy explained "this product is patented and the only product of this kind on the market. It has been ADA compliance approved". About 1260 blocks were used to cover the 100' long by 8' wide area.
Brian Deskins, employee of Miller Construction, cuts and sets the blocks to trim out the edge of the road.
A bioswale is a green infrastructure feature that is found along the full length of the road at Durbin next to the permeable parking lane. It is designed to remove water pollutants from surface runoff and encourage natural infiltration in place of flooding the sewer system following rain events. A bioswale is similar in construction to rain gardens. Its layers of gravel and soil are planted with native plants that absorb water and remove pollutants, and the shallow depression that it is built in, holds water to aid in silt and pollutants removal and water infiltration into the soil.
Gravel is dumped over the water and sewer lines.
Electrical wiring is ready for the transformers.
