· Lower Howards Creek Sanitary Sewer Improvements
The improvements are a Consent Decree project with a completion deadline of January 31, 2013. The project is expected to eliminate 13 recurring sanitary sewer overflows (SSOs) in the Lower Howards Creek Watershed and 13 of the documented 27 system-wide recurring SSOs. Palmer Engineering Company (PEC) is the Engineer of Record. The Lower Howards Creek Sanitary Sewer Improvements are separated into five individual construction contracts as listed below.
- Lower Howards Creek Wastewater Treatment Plant and Pump Station
The Contractor (Smith Contractors) continues work associated with the construction contract. The regularly scheduled progress meeting for the project is January 17, 2012. Work to-date includes all mass blasting on the site for both the WWTP & future WTP, specifically Influent Mag Meter Vault, Selector Tanks, Oxidation Ditches, Clarifiers 1, 2, 3 & 4, RAS/WAS Pump Station and Plant Drains Pump Station. Trench blasting has also been completed for most on-site process piping and the 24” plant effluent line. Boring & Jacking for 200+ feet of 36” effluent line is complete, along with Directional Drilling of the 24” effluent line nearing completion. 18” D.I. Influent force main has been installed from the pigging vault to the anaerobic selector basins & oxidation ditches. Oxidation ditch base slabs and walls are in place. The top slabs for the Oxidation ditches are currently being placed. Also in-place or complete are the building slab, steel structure & metal trusses for the Administration Building, Mag Meter Vault, Dewatering Building, Electrical Building, Clarifier No. 1 and the RAS/WAS Pump Station. Influent PS progress includes concrete slab placement, the majority of the concrete walls and reinforcing below grade. As of December 20, 2011 the LHC WWTP project is approximately 44% complete. The Owner and the Engineer continue to finalize recommendations for changes to the project that include modifications to the odor control system at the new WWTP and inclusion of a surge tank at the Influent Pump Station. These changes will impact the engineering contract and construction contract. Smith Contractors has provided the Engineer with a weather delay request per the contract documents for the months of January-April. The request totals 32 days for inclement weather. A change order for this project is expected to be on the January 19, 2012 agenda.
