Crumby P.E., Director of Public Works SUBJECT: AWARD CONSTRUCTION CONTRACT FOR PIER PLAZA STORAGE VAULT REPAIR PROJECT NO. BP1401 SUMMARY OF REQUEST: That the City Council adopt Resolution No. 6432: • Approving Plans and Specifications for the Pier Plaza Storage Vault Repair Project No. BP1401; • Awarding a contract for the Pier Plaza Storage Vault Repair Project No. BP1401 to Golden State Constructors, Inc. in the amount of$38,400.; • Authorizing the City Manager to approve additional construction in the amount of$4,000; and • Approving Budget Modification No. BA:1 4-07-01 for $10,000 in additional construction funding to account number 045-333-44000. BACKGROUND AND ANALYSIS: The City of Seal Beach owns, within its Public Right-of-Way, a storage facility. This facility is located adjacent to Main Street and to Ocean Avenue on the southeastern side of the pier. The storage room fronts to the 10'h Street Parking lot and is paved on the roof which allows for public viewing and vehicular and bike parking. During a site visit during the summer of 2012, staff became aware of possible structural deficiencies in regards to this storage room. The area directly above the storage room was cordoned off and a structural engineering firm, Dale Christian Structural Engineers, was contracted to perform a Limited Structural Investigation (LSI) to determine if the room was damaged and needed repairs or if the City could reopen the viewing area above the room. The LSI (Attached), given to the City in December of 2012, identified structural deficiencies in the storage room, including the roof. Due to these deficiencies, Agenda Item— F the engineering firm recommended that the parking/viewing area above the storage room remain cordoned off to the general public until the roof and other parts of the room be reconstructed. The City was able to budget for repairs of this storage room in the 2013/2014 Fiscal Year Budget. In August of 2013, Dale Christian Structural Engineers, the company that produced the LSI, was contracted to design the full structural repairs to the storage room. The project consists of constructing a concrete roof replacement, wall repairs and a new roll up door to the existing exterior storage room. On December 17, 2013, the City Clerk's office received one (1) bid with the following result: Rank Contractor Total Bid 1 Golden State Constructors, Inc. $ 38,400. This project was advertised in major public works publications as well as in local publications. Re-bidding this project would not be expected to generate additional bidders. In addition, the Engineer's estimate for this work was $40,000, and the low bidder is under that amount. Based upon the references, qualifications, work experience and cost, staff recommends selecting Golden State Constructors, Inc. as the lowest responsible bidder at $38,400. It is recommended that the City Council authorize the City Manager to approve contract changes and additional work for up to approximately (10% of-the award). The City Attorney's office has approved the construction agreement to be used for this project. The contractor has signed the agreement and it is included in this staff report. Exhibits to that agreement, including bonds and insurance documents will be provided to the City after award of contract. ENVIRONMENTAL IMPACT: This project complies with all requirements of the California Environmental Quality Act (CEQA) and is categorically exempt under section 15301 class 1 (d). LEGAL ANALYSIS: The City Attorney has reviewed and approved the City's standard Construction Contract. FINANCIAL IMPACT: Funds have been approved in the 2013-2014 Fiscal Year Budget for the Pier Plaza Storage Vault Repairs Project in the amount of $50,000. These funds are not sufficient to fund the construction of this project. The budget necessary to Page 2 complete this project is $60,000. The recommended actions include expenditures as follows: Item Amount Construction (award) $ 38,400.00 Contingency (10%) $ 4,000.00 Design(Dale Christian) $ 7,900.00 Materials Testing $ 4,700.00 Inspection (Casulas Construction Services) $ 5,000.00 Total $ 60,000.00 Budget Amendment No. BA:14-07-01 in the amount of $10,000 is recommended to provide sufficient funds for construction and to cover the necessary construction costs for this project. RECOMMENDATION: That the City Council adopt Resolution No. 6432: • Approving Plans and Specifications for the Pier Plaza Storage Vault Repair Project No. BP1401; • Awarding a contract for the Pier Plaza Storage Vault Repair Project No. BP1401 to Golden State Constructors, Inc. in the amount of$38,400; • Authorizing the City Manager to approve additional construction in the amount of$4,000; and • Approving Budget Amendment No. BA:14-07-01 for $10,000 in additional construction funding to account number 045-333-44000.

An interior and exterior observation of the concrete storage facility at the base of the Seal Beach Pier located at the intersection of Main Street and Ocean Avenue in Seal Beach, California was performed on October 17,2012.The purpose of the observation was to determine the extent of reported structural damage to the concrete structure. DESCRIPTION of STRUCTURE The structure is a single story concrete storage facility below grade, approximately 168 square feet, and estimated to have been constructed in the 1960's. The floor, ceiling, and four walls are concrete. The front and left exterior walls are approximately nine inches thick- The rear and right wall thickness is could not be measured. The interior ceiling height is 9 -7", and the overall height is ten feet. The ceiling concrete thickness is estimated to be five to six inches. An asphalt parking area occurs over the roof. The area over the structure has been barricaded to prevent access over the roof. CONDITION of STRUCTURE The left side wall has a horizontal crack along the top of the wall along the ceiling, and a vertical crack at the front corner. A diagonal crack occurs from the top rear to the base of this left wall. The front wall also has top of wall cracking along the ceiling line. A vertical crack occurs where the front wall and a site retaining wall intersect. The concrete ceiling has major damage due to scaling, spalling, and reinforcing steel corrosion. It appears that the ceiling may have experience some degree of structural failure. Temporary shoring has been installed to provide support.The condition of the interior concrete floor slab could not be determined due to the amount of debris covering the floor. It appears that the ceiling may have had moisture intrusion issues and this moisture may have caused the reinforcing steel to corrode,expand and cause severe deterioration. The interior surface of the rear and right side wall also appears to have scaling. Mr. Spitz City of Seal Beach Storage Facility—Limited Structural Investigation Our Job No. 12133 December 17,2012 Page 2 CONCLUSIONS and RECOMMENDATIONS The ceiling/roof slab in its current state appears unrepairable due to years of water intrusion through the slab and resulting steel corrosion. When reinforcing steel corrodes, the resulting rust expands the surface of the steel, causing pressure and cracking upon the surrounding concrete. The reinforcing steel and concrete damage is beyond repair and its load carrying capacity is severely compromised. Therefore,the parking area above this ceiling/roof shall remain cordoned off to the general public for both pedestrian and vehicular traffic. The temporary shoring that supports the ceiling/roof shall be considered to mitigate collapse and not considered to carry any live loads (people, vehicles). The ceflingtroof is not able to be repaired. The ceiling/roof slab needs to be removed and reconstructed with a new "one-way" structural reinforced concrete slab. The ceiling/roof slab after reconstruction will need to be protected with a proper waterproofing membrane to provide moisture protection and prevent similar damage in the future. As for the left and front walls, the cracking at the top of the walls appear to be due to corroding reinforcing steel. The corrosion is likely caused by moisture permeating the ceiling/roof slab. The vertical corner and diagonal cracks were most likely initially from thermal contraction and expansion. These cracks are now widening due to moisture intrusion causing corrosion of the reinforcing steel. These cracks initially were not of concern, but now due to the enlargement of these cracks, repairs will be required. The walls can be repaired. The cracks will need to be enlarged to expose the reinforcing steel for observation. All steel corrosion will require cleaning and sealing with an anti-corrosion compound prior to any crack repair. After the steel treatment, the wall crack should be patched with epoxy injection or with a proper repair mortar approved for such repairs. Please consult the"Sika7'website for such available approved products. The rear and right walls appear to be structurally sound, and require minimal repairs.The information in this report is preliminary and based on an observation of surface damage. A follow up observation may be required if additional damage is exposed once demolition is complete. The opinions expressed in this report are preliminary based on a limited site observation and on what could be readily visually observed under the circumstances presented. No destructive testing or testing of any kind by this office was within the scope of this report. Additional site visitations will likely be required before and/or during the repair(or retrofit design) process should questionable conditions arise, or should additional"as-built" information be encountered. Please contact this office for scheduling. The Structural Engineer reserves its right to supplement this letter if additional facts are discovered or at the conclusion of final investigation if one is requested. The recommendations contained herein are not intended to be a redesign for permitting and are submitted for general informational purposes only. Please do not hesitate to contact me at my office should you have any questions regarding the above mentioned project. Sincerely, Dale Christian,S.E.2705 President,C.E.O.0
