In order to resolve these discoveries and complete the project, modifications to three existing contracts are required: • A modification to Professional Services Agreement No. 8956 (CCS) with Harley Ellis Devereaux Corporation in the amount of $76,544, for a total agreement amount of $487,423, for additional design services. • A change. order to Contract No. 9258 (CCS) with Thomco Construction, Inc. in the amount of $462,000, for a total contract amount of $3,427,328, for additional construction work. • A modification to Contractual Services Agreement No. 9260 (CCS) with Design Space Modular in the amount of $28,922, for a total lease amount of $338,722, to extend the trailer lease for another two months.

Discussion The Big Blue Bus administration building renovation began on December 20, 2010. Upon further investigation during construction, additional unforeseen conditions were discovered, delaying the completion of the project. The unforeseen conditions that require resolution to complete the project include: • Relocating existing fire sprinkler lines, electrical lines, plumbing vent and water supply lines to clear a path to install new heating, ventilation and air conditioning ductwork. Making corrections to existing fire rated shafts that do not meet current building and fire codes. Installing rated walls to two existing stairwells as required per current building and fire codes. Bracing existing wall framing at several locations of the building to the ceiling as required per current building codes. Purchasing and installing additional .panels, conduit and wiring for the main distribution frame room (main information technology room) to provide adequate power supply. Removing and replacing existing damaged mortar bed flooring in the restrooms.' Repairing water damage at the existing walls of-the east stairwell due to improper waterproofing. Repairing termite damage found under the existing flooring in the lobby area. There were no as-built plans for the facility, and therefore staff could not anticipate the extent of code corrections required once the walls were opened and deficiencies discovered. 3 Modifications to three existing contracts are required to increase scope of work and address the unforeseen conditions. Staff estimates that addressing the conditions will delay the completion date by an additional two months. The total project delay is expected to be approximately six months to November 2011.
