RE: Amendment for Professional Services – Vista Canyon Bridge Engineering Design Support During Construction and Project Close Out
Ms. Lillio:
Dokken Engineering is pleased to submit this scope and fee amendment to provide engineering design support during construction and prepare project close out documentation to complete the Vista Canyon Road Bridge over the Santa Clara River in the City of Santa Clarita . A breakdown of proposed support tasks is provided below:
Task 1.1: Engineering Design Support During Construction Dokken Engineering will be available to support the construction of the Vista Canyon Bridge and assist with interpretation of the contract documents for the overall project. Engineering Design Support during Construction includes the following for a Lump Sum Engineering Fee of $275,000:
Construction Meetings: Dokken Engineering will attend the pre -construction meeting and assist with preparation of meeting notes, answering questions, and providing clarification to the plans and project specifications as required. The Dokken team will be available to attend construction meetings (virtually) on an as-needed basis and attend up to two construction meetings in-person as directed by the City.
Site Inspection Visits: Dokken Engineering will conduct up to eight site visits to aide in resolving potential construction Requests for Information (RFI’s) and assist the Construction Management team in observing the progress of construction. The eight site visits will be in addition to any site visits conducted during weekly construction meetings that the Dokken team attends in person. Dokken Engineering will notify the Construction Management team of any inconsistencies between the present field conditions/construction progress and the project plans and specifications.
Respond to Requests for Information (RFI’s) and Change Requests (CR’s): Dokken Engineering will provide ongoing consultation and interpretation of contract documents (project specifications and Vista Canyon Bridge plans) as requested by the Contractor through the Construction Management team and the City.
Written responses will be provided for RFI’s and CR’s regarding the Vista Canyon Bridge foundation, substructure, superstructure, bridge approach slab, and crash cushions, along with approach guard rails to be installed below the existing Caltrans SR-14 bridge. Supplemental or revised drawings and specifications may be issued to provide clarity to the Construction Management team and the Contractor in support of RFI’s, CR’s, and design changes due to differing site conditions.
Review of Construction Submittals: Dokken Engineering will review construction submittals for: shop drawings (precast concrete girders, including review of bridge profile and camber calculations), concrete mix designs, temporary shoring plans for Vista Canyon Bridge related earthwork, Vista Canyon Bridge related falsework plans, Cast -in-Drilled-Hole Pile (CIDH) pile installation plans, driven pile installation plans, and temporary water diversion plans (as -needed) for conformance with the project plans, specifications, and permits. Dokken Engineering will also provide review and analysis of CIDH pile gamma -gamma logging reports, recommend supplemental cross sonic logging tests and reports as needed, and work with the Contractor and Construction Management team to evaluate any CIDH pile mitigation repair strategies that may be required.
1450 Frazee Road, Suite 100, San Diego, CA 92108 Tele: 858 514-8377 Fax: 858 514-8608 www.dokkenengineering.com Contract Change Order (CCO) Support: Dokken Engineering will assist the City’s Project Manager and Construction Manager in reviewing CCO requests. Dokken Engineering will review applicable CCO’s and work with the design team discipline leads (Civil, Bridge, Signals, Landscape, Lighting, Utilities, and Water) to prepare a construction cost estimate for the changes associated with the CCO, assist with providing new or revised technical specifications for change order work, and provide a recommendation to the City for the request.
Supplemental Engineering Support Services: Dokken Engineering will assist the City’s Project Manager with any questions and requirements for working within Caltrans Right -of-Way, provide assistance with processing the Caltrans Encroachment Permit, and assist with the application to obtain a bridge number through Caltrans local assistance.
Task 1.2: Project Close Out
The Dokken Engineering team will work with the City’s Project Manager and Construction Manager to close out the Vista Canyon Bridge portion of the project. The Dokken team will ensure that all work performed for the Vista Canyon Bridge was completed pursuant to the project plans and specifications. Project Close Out includes the following for a Lump Sum Engineering Fee of $45,000:
Final Inspection: The Dokken Engineering team will complete a final walk -through near the end of construction activities to perform the final inspection of the Vista Canyon Bridge work with the City’s Project Manager and Construction Manager to develop a ‘punch -list’ of pending construction items to be completed prior to project close-out.
As-Built Plans: At completion of construction, the Dokken team will prepare the final record drawings (as - built plans) for the Vista Canyon Bridge based on markups received from the Construction Manager and Contractor, along with supplemental or revised drawings from addenda or RFI’s. Vista Canyon Bridge Drawings will be provided in both PDF and in full -size mylars. Dokken Engineering will work with the design team disciplines leads (Civil, Bridge, Signals, Landscape, Lighting, Utilities, and Water) to assemble the final record drawing set for the Vista Canyon Bridge project. Dokken Engineering will assist the City with obtaining product literature, recommended maintenance guides, and warranty information for features installed as part of the project.
The proposed amendment fee for providing Design Support During Construction and Project Close Out for the Vista Canyon Bridge over the Santa Clara River is $320,000, lump sum, to be paid in increments towards the successful completion of the following milestones:
