HomeMy WebLinkAbout13 - C-3312 - Ocean Pier RehabilitationAugust 14, 2001 CITY COUNCIL AGENDA ITEM NO. 13 TO: Mayor and Members of the City Council FROM: Public Works Department SUBJECT: OCEAN PIER REHABILITATION — APPROVAL OF PLANS AND SPECIFICATIONS AND AUTHORIZATION TO ADVERTISE, CONTRACT NO. 3312 RECOMMENDATIONS: 1. Approve the plans and specifications. 2. Authorize staff to advertise for bids. DISCUSSION: On July 11, 2000, the City Council approved a Professional Services Agreement with Noble Consultants, Inc., to prepare plans and specifications for rehabilitating the Newport and Balboa Piers. Staff from General Services, Utilities, Fire and Lifeguard Operations, and Public Works provided input into the project. Public Works Staff also met with the Assistant City Manager and representatives from the restaurants on each pier. Furthermore, much effort was made to coordinate the pier work with other construction projects that are scheduled to be concurrent with the pier rehabilitation. SCOPE OF WORK: The piers are in need of their biennial repairs and a complete rehabilitation to restore their original structural integrity and provide an additional service life of approximately 20 years. The base contract includes: • Removing and replacing pier gates and signs • Replacing 15 defective piles, various stringers, pile caps, hair pins, bolts, and cross bracing • Removing abandoned wiring and utility conduits • Reinstalling all communication, power, gas, water, and sewer conduits under the deck or within "pipe chases" in the deck to facilitate future access • Installing a 4 -inch fire main on Balboa Pier • making the roof of the Lifeguard Workshop (under Newport Pier) waterproof • Rehabilitating the lifeguard boat access way (also under Newport pier) • Replacing the timber subdeck and the concrete deck on both piers SUBJECT: OCEAN PIERS REHABILITATION — APPROVAL OF PLANS AND SPECIFICATIONS AND AUTHORIZATION TO ADVERTISE, CONTRACT NO. 3312 August 14, 2001 Page 2 • Replacing the pipe handrail on Balboa Pier with a wooden handrail • Replacing fishing benches and cutting boards on both piers • Installing signs prohibiting vehicles weighing more than 3 tons (6,000 pounds) from using the piers Three additional bid items that the City Council may include in the award, if desired, are: 1. Replacing the wooden railing at Newport Pier (the base bid requires the contractor to only protect the existing railing). 2. Cleaning marine growth from piles (will reduce wave forces on the piers). 3. Installing removable concrete covers in the deck adjacent to most pile caps (to enable future pile replacement without having to cut through the new deck). PROJECT SCHEDULE Barring unforeseen circumstances, bids will be opened in mid September 2001, and the contract may be awarded at the September 25, 2001, City Council meeting. After contract documents are executed, replacement timber members and piles must be ordered. Assuming 60 days for delivery, construction could commence as soon as December 1, 2001. Construction will then continue for approximately 5 months, with deck and handrail replacement being performed during the latter stages of work. The final items of work will be to reinstall sinks, cutting boards, benches, gates, and signs. For safety, the piers must be closed to the public during deck and railing replacement. Since the concrete deck must be replaced in stages, Each pier will be limited to only a two month closure . In addition, because the new deck is thicker than the existing deck, one -inch ramps must be built within the entries to Ruby's Restaurant. The City will reimburse Ruby's for building their three ramps. No ramps are needed at Newport Seafood since the restaurant is elevated above the deck. Work at Balboa Pier will be performed concurrent with the Balboa Pier restroom reconstruction and Phase 1 of Balboa Village construction. The pier contractor will use a portion of the Balboa parking lot for staging pile replacement, but must vacate the area by April 1, 2002, for parking lot reconstruction under the Balboa Village contract. The pier restroom contractor will be using a portion of the A Street parking lot for his staging area (see attached Location Map). PROJECT COST: Noble's Engineer's Estimate of $2,140,000 provides for constructing the base contract items listed above. This estimate is also predicated upon rehabilitating both piers under a combined contract and requiring that work be performed concurrently on both piers within a five -month construction period. Staff and Noble feel the combined contract is desirable for the following reasons: SUBJECT: OCEAN PIERS REHABILITATION — APPROVAL OF PLANS AND SPECIFICATIONS AND AUTHORIZATION TO ADVERTISE, CONTRACT NO. 3312 August 14, 2001 Page 3 • There are few contractors that are qualified to perform such work • By virtue of a greater contract amount, a combined contract could attract more bidders and save the City money • The contractor could afford more field crews to complete the work within the specified construction time period The three additional bid items (ABI) mentioned above that could be included in the award if funds are available add to the Engineer's Estimate. The ABI for cleaning off marine growth that has accumulated over the years on the piles is estimated at $75,000. The ABI for replacing the deteriorated, but salvageable, wooden railing on Newport Pier is estimated at $75,000. The ABI for constructing removable concrete covers across the concrete deck at each pile cap to facilitate pile replacements at a future date is estimated at $60,000. Upon award of the construction contract, Staff will recommend the City retain a construction manager to manage and inspect the project. Staff estimates that such services will cost approximately $86,000 for the five months of work. The design consultant, Noble, is already under contract to provide shop drawing reviews and plan clarifications to the construction manager. The project will also involve considerable involvement from Public Works, General Services, and Utilities departments. The project is being funded with proceeds from the City's $4,770,000 settlement of the 1990 American Trader oil spill. $2,100,000 (44 percent) of the remediation settlement was allocated for pier rehabilitation. Total estimated construction costs are as follows: Base Bid $2,140.000 Contingency (10 percent) 214,000 Additional Bid Items (pile cleaning, Newport railing, pile cap covers) 210,000 Construction Management 86,000 Total Estimated Construction Cost $2,650,000 CONSTRUCTION FUNDS: The following account balance is available for construction: Account Description Account Number Amount Newport/Balboa Pier Rehabilitation 7295- C5100565 $ 2,077,000 SUBJECT: OCEAN PIERS REHABILITATION — APPROVAL OF PLANS AND SPECIFICATIONS AND AUTHORIZATION TO ADVERTISE, CONTRACT NO. 3312 August 14, 2001 Page 4 If additional funds are required, the City Council may elect to divert some of the proceeds allocated for other oil spill remediation projects into the pier allocation. Other projects include Corona del Mar Beach Improvements ($476,000), Ocean Front Walkway and Lighting ($449,000), Beach Access Walkways ($290,000), Lifeguard Communications Center Improvements ($500,000), and Marine Education Facility ($500,000).
