PROJECT SPECIFICATIONS

GENERAL REQUIREMENTS

PART 1 – SUMMARY OF WORK (SECTION 01 11 00) & DEFINITION OF CLINs (01 27 00)

1.1 WORK COVERED BY CONTRACT DOCUMENTS

A. General: All work outlined below will be performed under a single contract.

B. Project Location: This project is located at the John Muir National Historic Site, on federally owned land managed by the National Park Service. The park preserves the historic John Muir House, landscaped grounds, and historic orchards. The site is on Alhambra Avenue off of Highway 4 in Martinez, California, and the delivery address is the park visitor center at 4202 Alhambra Ave., Martinez CA 94553.

C. Project Background: The irrigation system at John Muir NHS is critical to the health and maintenance of 9 acres of historic landscape around the John Muir House. This project will install a new irrigation system to replace the existing system, which is 15 to 30 years old and failing from age and breakage.

The existing irrigation system supports the site’s historic landscape of mature ornamental trees and restored orchards and gardens. It serves a one-acre area of trees and landscaping around the historic house, which sits on a hill at the south side of the site. It also irrigates a one-acre apple orchard downhill to the east, and a one-acre peach orchard to the north. The new system will extend irrigation to a one-acre vineyard/orchard planted west of the house and a two-acre orchard west of the creek.

The existing irrigation water source is supplied by domestic city water via a meter at the park entrance (4202 Alhambra Ave). The POC will be the domestic 5/8” water meter located in an unpaved planter bed adjacent to the park entrance at 4202 Alhambra Ave. An additional water meter located on the NW side of the site (near the Martinez Adobe) will supply water to irrigation lines on the West side of the site. All irrigation parts downstream of the meter/POC will be replaced unless indicated otherwise on the the Plans.

Two existing historic hand-dug, rock-lined wells are also connected to the existing irrigation system and shall be reconnected to the new irrigation system. The existing well infrastructure including pumps, captive air tanks and backflow preventers shall be retained.
