PENCO provided civil engineering planning and design and survey services for this
22-acre medical research facility renovation and a new administration facility building.

Work included on-site preliminary planning and engineering for grading, utilities, demolition of some existing buildings, relocation of buildings, drainage design, and hydrology study.

PENCO prepared a major on-site utility corridor design, including all hot water, chilled water, domestic water, and dry utilities. PENCO was able to meet the client’s challenging design for installation for all on-site utilities in a very narrow corridor.

PENCO also provided survey services including on-site topographic design and construction staking.

The project was processed and approved through the City of Irvine and Irvine Ranch Water District (IRWD).
