A summary of the construction cost is as follows: Original bid amount: Actual Cost of Bid Items Constructed: Total Change Orders: Final Amount of Contract paid to TE Roberts: Reimbursement from Newport Bay Marina: Reimbursement from Orange County Sanitation District: Actual Final Cost to City for Contracted Work $3,511,515.00 $3,245,955.00 $666,981.29 $3,912,936.29 ($80,000.00) ($55,297.66) $3,777,638.63 This final overall cost of the construction contract to TE Roberts was $3,912,939.26 or 11.43% over the original bid amount. However the actual cost to the City for said work was $3,777,638.63 or 7.58% over the bid amount when one factors in the two reimbursements associated with the project. This contract cost overage was a combination of two factors; changes in the actual amounts of contract bid item quantities paid for, as well as agreed upon change orders for work not originally included in the contract. In the first case, the actual cost of contract bid items constructed was $265,560.00 less than the original bid amount. The majority of the cost savings in bid items is attributed to the deletion of the 12 -inch PVC water main within the alley between Finley Avenue and 32nd Street. During construction, the contractor discovered that the original cast iron water main in this alley 4-2 Newport Blvd Water Main Replacement Notice of Completion for Contract No. 5481 (15W02) September 27, 2016 Page 3 was previously replaced with a newer 12 -inch PVC pipe, which is in good condition. Staff determined that it was not necessary to replace this pipe. Additional savings related to bid item changes was attributed by an offsetting reimbursement by the Newport Bay Marina project. During the design phase, staff included water infrastructure improvements in the plans that were later required to be constructed by the Newport Bay Marina development. City staff negotiated with the developer to have the City's contractor construct their conditioned water infrastructure improvements within the public right-of-way and then received reimbursement check from Newport Bay Marina for this effort in the amount of $80,000.00. The project also generated several change orders during the construction phase which totaled $666,981.29. A large portion of the change order work was attributed to unforeseen utility conflicts as well as dealing with high groundwater (tidal) level. Due to many unknown/unmapped, buried utilities pipes (which are common with older streets) such as Newport Boulevard, the contractor had to revise the pipeline alignment in order to avoid utility conflicts. In addition, we encountered a significant amount of groundwater at depths as high as 2 feet below ground level. Due to the high tidal groundwater level, in combination with our efforts to minimize business and traffic impacts, the contractor needed to install an extensive dewatering system and also occasionally work at night which impacted production rates. One of the directed change orders was associated with the Orange County Sanitation District (OCSD) Sewer Force Main improvements on West Coast Highway. As construction of the project commenced, staff requested TE Roberts to add the replacement of a water main across West Coast Highway by Dover Drive that was originally going to be replaced by OCSD as part of their Sewer Force main project on Pacific Coast Highway. The original water main was removed by OCSD's contractor, Kiewit, in September 2014 to make way for their replacement sewer force main. Kiewit was to have this water main replaced prior to the summer months, however was behind schedule and was not going to be able to provide the necessary resources to complete the work per the approved schedule. Since this was one of two water mains that served the Bayshores community and is also a critical back feed to the Lido Island, the City negotiated with OCSD for our contractor (TE Roberts) to install the necessary waterline and complete this work for OCSD. The cost of this work was charged to the project; however, OCSD has since reimbursed the City its cost of $55,297.66 for this work. A summary of the project schedule is as follows: Estimated Completion Date per Baseline Schedule May 20, 2016 Notice to Proceed June 22, 2015 Contract Completion Date with Approved Extensions June 24, 2016 Actual Substantial Construction Completion Date April 22, 2016 The project was substantially completed as of April 22, 2016. Some miscellaneous close-out items, operation and maintenance turnover, and post -substantial completion activities needed to be finalized prior to this Notice of Completion action. 4-3 Newport Blvd Water Main Replacement Notice of Completion for Contract No. 5481 (15W02) September 27, 2016 Page 4 ENVIRONMENTAL REVIEW: On May 12, 2015, City Council found this project exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15302 Class 2C (replacement or reconstruction of existing utility systems involving negligible or no expansion of capacity).
