$30-50 million dollars in construction revenue over a 2 year span and commencing in November of 2010
The first contract (Phase 1), D-525N (L-40 Modifications) and Miscellaneous Features, includes clearing, grubbing and dewatering activities, demolition work, establishing on site borrow and disposal areas, earthwork modifications to about 15,000-linear feet of the existing L-40 levee, installing dam monitoring instrumentation, and emplacing turf reinforcement mat and soil cement. The project also includes construction of a six-acre wildlife wetland area and auxiliary spillway, S-530, located in D-525N.
These Phase 1 features will reduce the amount of seepage loss from the adjacent LNWR, also known as Water Conservation Area 1. Reducing seepage will help increase the amount of water that remains in that natural system, especially during dry periods. Maintaining the additional water will allow for ecological habitat improvements in the LNWR.
A second contract (Phase 2) will complete the Site 1 Impoundment project. Work will include additional site clearing, grubbing, miscellaneous demolitions, excavation and filling, construction of inflow and seepage pump stations, associated impoundment structures, canal improvements, D-525 embankment, embankment instrumentation, placement of geocells on embankment exterior, placement of smooth flat plate soil cement on embankment interior and other miscellaneous site work such as security fencing, gates, paving, storm structures, site pads, weep holes and a recreational area. These contract tasks are only draft; the Corps will finalize features in the contract design, which it anticipates completing in 2011.
The Site 1 Impoundment Project is a 50/50 cost-share. The Corps anticipates Phase 1 construction to go from October 2010 through October 2012, and Contract 2 construction from September 2011 through March 2014.
Lodge Construction, Inc is operating the on site batch plant for the soil cement at this project. The batch plant went online in April 2011. Strict Quality control over this process is demanding. Lodge Construction's team is working with our subcontracting core to continue top quality work from batch to placement.
