 | Preliminary and final civil design of Phase I & II expansion of existing hospital facility (from current 4.7-acre to ultimate 8.8 acre site). Sewer capacity analysis and feasibility study to determine adequacy of "G" Street sewer system to provide service for the proposed Scripps Memorial Hospital, Chula Vista site. Analysis included a baseline assessment of the existing 18" and dual 12" systems, assessment of the potential impact of the hospital expansion and forecasting of ultimate sewage flows for the two-square mile "G" Street sewer basin. Construction PS&E included: - Site development and parking facilities,
- Replacement of 600 LF of 6" cast iron water line,
- Widening of "H" Street and 5th Avenue, including utility and traffic signal, relocation, and installation of raised median,
- 1,600 LF of 8" water main,
- 1,000 LF of 39" storm drain in 5th Avenue,
- Private storm water and sewer pump stations, and
- Demolition of existing shopping center site with associated utility relocations.
Survey effort included boundary survey, research of County of City of Chula Vista records, and horizontal and vertical control for aerial photogrammetry; supplemental topographic surveys of sewer, storm drain and dry utilities throughout the project site and adjoining shopping center. Efforts also included cross-sections and topographic survey along “H” Street, 5th Avenue and the driveway access at the adjoining elementary school. Additional survey services included construction staking for grading and excavating, building foundation and gridlines, bolt patterns, sewer pump station and all on-site and offsite improvements along “H” Street and 5th Avenue. Additional topographic surveys were performed to confirm locations of existing column lines. |
