FUNDING SOURCE: Funds are programmed in the Wastewater Permanent Capital Maintenance Fund Balance (PCMF) account number 200-43370-534-0. BACKGROUND: The Wastewater Treatment Plant (WWTP) Inflow and Collection structure (Headworks) has reached its design life and has begun to fail. The facility was constructed in the 1950s with two major expansions undertaken 14 years ago. Over time, the Headworks structure has deteriorated due to age and highly corrosive conditions typically experienced at a WWTP entry point. Hydrogen sulfide has deteriorated the concrete causing structural failure. Significant facility replacement and upgrade is necessary to continue to function and comply with updated TCEQ regulations. Bids were opened on April 19, 2012 with seven bids received as follows: Legacy Contracting $2,757,600 RAMA Enterprises $2,856,750 Archer Western Contractors $2,983,000 Red River Construction Company $2,999,300 0:lagenda12012106-19-121Headworks at WWTP June 13,2012(2:54PM) Gracon Construction $3,151,200 Dake Construction $3,265,750 Graham Construction $4,166,100 The bids were above the engineer's estimate for this project with the increases primarily in the electronic controls and circuitry. Staff has reviewed the bid and negotiated a reduction in the contract price by eliminating part of the electronics and circuitry that can be added later by staff as time and funds permit. This reduced contract price is reasonable and should be accepted to allow the construction to proceed. Staff recommends approval. 0:\agenda 12012106-19-121Headtirorks at W WTP .tune 13,2012(4:08PM) �1 Cy cc pp CC pp �•+ 4 O � V O C° G Q �G'7 9 G Buz it ^n � v e c �.
