Project Overview
Considered the first phase of the New Performing Arts Complex project, the Wilshire Chiller Plant will be relocated adjacent to its original location to accommodate the future construction of the New Performing Arts Complex in its original building footprint. The facilities deliver temperature control to the buildings in its vicinity, including the Wilshire Center. The new facility will provide the same service to the current buildings in addition to the new Performing Arts Complex. The relocation of the infrastructure will be carried in coordination with the local utility, Southern California Edison (SCE).

Q2 2025 Project Update
Wilshire Chiller Plant Relocation
April
Pile drilling commenced in early April. As the holes were excavated, reinforcement bar cages were placed inside, followed by concrete pouring and a curing period.
Trenching for the new mechanical water lines commenced, with piping installation beginning in early April. Demolition of electrical and fiber encasements around the building perimeter progressed and continued until the end of the first week of April. As sections of encasements were removed, their trenches were filled in and compacted. In the second week of April, over-excavation and compaction of the chiller building were carried out, followed by survey work for elevations, flooring, and building corners.
Electrical and mechanical piping trenching and installation were underway in the third week of the month. The new gas line near Lemon Street was completed by the end of the month, with backfilling finishing by the second week of May.
The installation of a new building sewer line commenced in the final week of April. Over-excavation for the compressor room was completed at the start of May.
May
Installation of the reinforcement bar for the foundation grade beams began in early May, followed by the placement of the foundation footings after its conclusion in the second week of the month. Concrete pours took place in the third week of the month.
Crews began addressing the scope of work for Increment Two at the arts yard by setting the gas and sewer lines in place in mid-May; the lines were later backfilled.
June
The construction of the concrete masonry unit (CMU) walls are progressing well, with the first lift completed by the end of the first week of June, followed by the second lift. Scaffolding for the second lift is expected to be installed at the end of the first week of June.
Inside, the placement of electrical and mechanical underground conduits is underway and expected to be finished by the end of the first week of June. Simultaneously, electrical and sewer lines will be installed in the compressor rooms. The layout for the green screen footings and cranes has been set.
A series of change orders have been issued to address the rerouting of unforeseen conditions and subsequent time delays associated with this added scope of work. Change Order No. 1 was previously approved to allow for the rerouting of the unforeseen conditions; Change order No. 2 will be presented to the Board of Trustees at the second meeting in June for compensable time delays involved in rerouting the unforeseen conditions for the Board’s consideration.
