1 One Gateway Plaza Los Angeles, CA < metro.net 32 CONSTRUCTION COMMITTEE FEBRUARY 19, 2015 SUBJECT: ACTION: REHABILITATION OF LANKERSHIM DEPOT PHASE TWO APPROVE RECOMMENDATION TO INCREASE CONTRACT MODIFICATION AUTHORITY RECOMMENDATION Approve an increase in Contract Modification Authority (CMA) to Contract No. C0984R with DRP National, Inc., for the Lankershim Depot Rehabilitation Project Phase Two, to provide funding for differing site conditions, extra work and plan modifications identified in the amount of $150,000 increasing the current CMA from $332,034 to $482,034. The remaining Life-of-Project (LOP) budget after this action is $123,934. ISSUE Contract C0984R is a firm fixed price contract funded by Prop. C funding and the City of Los Angeles for completing the second phase of the restoration construction work on the historic train depot. The first phase of the construction was completed under a previous environmental contract. It included removal, abatement of hazardous materials including contaminated soils, roofing asbestos and lead-based 'paint. The current Phase Two reconstruction work by DRP National includes seismic strengthening of the structure, new electric and plumbing systems, restoration of the platforms and signage as well as rehabilitation of damaged siding, eaves, windows and doors to bring the building up to current code. During the Phase Two construction of the project, various potential contract changes for design modifications have been identified and require additional CMA. Approval of additional CMA will allow staff to process contract modifications for work performed by the Contractor and who submitted Requests for Change that have now been found to have merit by Metro staff. No additional funds are required for the (LOP) budget. The approved LOP Budget of $3,600,000 is sufficient to complete the project.

2 DISCUSSION Metro is rehabilitating the historic Lankershim Depot as approved by the Board under Project Number Lankershim Depot Transit Center Rehabilitation Project. During the current Phase Two construction effort, a number of differing site conditions were discovered that required re-design, replacement, or renovation of the structural and architectural components of the building once these areas were exposed. The most significant impacts involve structurally deficient members, including framing and support members due to the age of the building. The impacts ranged from extensive lumber replacement at the platform area -this area had existing concrete cover, to new concrete foundations, rotted out joists and sill plates, the need to strengthen perimeter brick walls, providing a connection between the existing columns and foundations, and reframing inadequate shear walls. There is currently insufficient CMA to cover the identified Contract Modifications. Staff requests approval of an additional $150,000 of CMA for the Rehabilitation of Lankershim Depot Phase Two Project to complete this project. A detailed matrix of Contract Modifications/Change Orders is shown in Attachment B. DETERMINATION OF SAFETY IMPACT This Board action will not have an impact on established safety standards for Metro's Construction Projects. FINANCIAL IMPACT The funds for this action are included in the FY14 Budget in Cost Center 8510, Construction Contract under Project The approved LOP Budget of $3,600,000 is sufficient to complete the project. Since this is a multi-year project, the Project Manager and the Executive Director, Transit Project Delivery is responsible for budgeting in future years. Impact to Budget The funding for this action will come from Prop. C 10% funding and from the City of Los Angeles. No other source of funds was considered since this action is within the Life-of Project Budget. The funds are not eligible for bus or rail operating expenses, but are eligible for specific capital expenses. 2

3 ALTERNATIVES CONSIDERED The Board may decline to approve the recommended actions. This is not recommended as it will prevent the issuance of Modifications for work performed by the Contractor who submitted Requests for Change that have now been found to have merit by Metro staff.
