The contractor is unable to finish the project by the original completion date of September 24, 1981 due to circumstances beyond his control. A time extension of 2.3 working days will change the contract com pletion date to October 27, 1981 and give the contractor sufficient time to finish this project. It is my RECOMMENDATION: That Council approve the resolution granting a 23 day time extension to Dyno Construction, changing the contract completion date to October 27, 1981. BOARD/COMMISSION RECOMMENDATION: Not applicable. DISCUSSION: Dyno Construction was awarded the contract dated June 15, 1981, by Resolution No. 10464 far the construction of the Chula Vista Transit Center at Woodlawn Avenue/"H" Street. The contract required that work commence no later than June 30, 1981 and allowed 60 working days to complete the project (last day is September 24, 1981). Attached is a listing of chronological events for the period from May 5, 1981 to September 8, 1981. A major delay was encountered by the contractor at the start of the project because the controller for the signal at Woodlawn Avenue/"H" Street built by MTDB was in the wrong place and needed to be relocated. On June 1, the City sent a letter to MTDB requesting that this controller be relocated. MTDB was very hesistant to agree to the relocation and requested that the City redesign the landscaping on the island to accommodate the misplaced controller. The Landscape Architect and City Engineer considered a redesign and decided that it would have a significant negative aesthetic impact on the transit center and reaffirmed the City's request that MTDB relocate the controller. It should be noted that the staff at MTDB was very busy during this time (June-July) with last minute preparations for the startup of trolley service on July 26 and I am sure that the controller relocation was a low priority item for them. The Form A-113 (Rev. 11/79) Page 2, Item 16 Meeting Date 9-22-81 controller was finally relocated on August 3, 1981. Prior to that date, the contractor was able to do some minor work such as the installation of irrigation piping but none of the major work such as planters, tree wells and pavers. Once the contractor got started, a second conflict was encountered causing additional delay. The underground conduit for lighting and telephone installed by MTDB was not located in the area specified on the plans and was struck by the contractor's equipment. This necessitated repair and rerouting of the cond uit by others and was finally resolved on September 8, 1981. As of September 24th, the contractor will have had only 30 days that he could perform work on contract items that could be scheduled around the conflicts. Ordinarily, the contract would have been extended those 30 working days, but Dyno Construction has prepared the attached bar graph showing that work can be completed by October 27, 1981. The Engineering staff, in reviewing the problem s encountered, believes that a 23 working day extension of time to October 27, 1981 is justified and recommends approval. The shelters and kiosks furnished by the City were received on September 14, 1981 and are available for assembly and setting by the contractor when appropriate.
