Project Description: (Approx. quantities) The construction contract includes all work associated with installing a multi-stage granular filter and drain around and beneath existing 48" to 60R conduits; remove approximately 50 linear feet of existing RCP-lined, CMP conduit and replace with a new section of steel pipe and air shaft; place a compacted, random fill stability berm; place riprap protection at the outlet of the drainage layer and conduit; and other appurtenant work for grading requirements at the downstream end of 4 (four) high hazard dams in the vicinity of Lincoln, Nebraska It will be necessary to perform the work at each site in sequenced phases in order to mitigate against the potential for dam-safety related issues. Filter installation will require a relatively deep and narrow excavation utilizing specialized techniques and temporary structural measures that will minimize the unsupported length of pipe and/or directly provide for its temporary support. Excavations will extend into groundwater and significant consideration should be given to minimizing subgrade disturbance and managing groundwater. It is anticipated that a significant dewatering effort utilizing a system of wellpoints and associated pumping equipment will be required for at least one of the dam sites. The anticipated well point system should be capable of covering a minimum length of 150 lineal feet, and dewatering materials that are 5 to 10 feet thick, have a transmissivity of up to 240 ft/day, and a hydraulic conductivity with specific yield of up to 0.01. The Contractor will be required to develop and submit for approval excavation plans that details their proposed excavation process and all supported designs for temporary structural measures and dewatering systems. The Contractor will also be required to develop detailed drill plans, surveillance and contingency plans that outline critical procedures and appropriate responding actions that would be undertaken if adverse conditions develop. The estimated construction cost of this project is between $2,000,000 and $2,600,000. The Contractor will be required to commence work within 10 days after notice to proceed and complete the work 720 calendar days after receipt of Notice to Proceed. Provisions will be included for liquidated damages in case of failure to complete the work in the time allowed. Performance and payment bonds will be required. Bonding documents including the power of attorney shall bear an original signature by an officer of the surety.
