GENERAL REQUIREMENTS

By: Diane Ochi Tsuji Date: 4/2/2023

PART 1 – SUMMARY OF WORK (SECTION 01 11 00)

1.10 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 Chaparral Picnic Area, at the end of State Highway 146 on the west side of Pinnacles National Park, approximately 8 miles east of Soledad, California. The delivery address is the west park maintenance facility at 2011 Chaparral Rd, Soledad, CA and the lat/long coordinates are 36.491757, -121.209242 NOTE: Pinnacles National Park is divided by a mountain range into east and west districts that are not connected by road. State Highway 146 does not continue through the park—it dead-ends on the east and west.

C. Project Background: The Chaparral Picnic Area is the main trailhead for the most popular west side trails, seeing approximately 36,200 visitors a year. Summer temperatures are often over 100 degrees and the natural landscape has limited tree cover. There are no shaded areas where visitors can rest or eat. The existing picnic tables are weathered, splintered and sagging from sun exposure.

The park intends to have 5 shade structures purchased and installed at Chaparral picnic area.

One larger shade structure will cover a new fully accessible group picnic site near the existing restroom. The site will be paved with stabilized decomposed granite and have space for 3-4 tables. A new decomposed granite path meeting ABA standards for Outdoor Recreation Access Routes (ORAR) is needed to connect the group picnic shelter to existing visitor amenities at the trailhead. The shade structures are specified with brown colored steel posts and roofing for durability, low maintenance, and compatibility with the surrounding landscape.

PINN – PMIS 285631 GENERAL REQUIREMENTS Page 2

Four small shade structures of similar design will be purchased and installed further north in Chaparral picnic area to cover single tables on the existing trail. Any needed accessibility improvements for trails to these picnic sites will be done in-house by park staff.

There is one scope option to provide and install a shade structure over existing benches and paving at the end of the accessible section of Prewett Point Trail, near West Pinnacles Visitor Center.

D. Definition of Contract Line Items:

1. Contract Line Item No. 1: This item shall consist of:

Provide and install (1) 14’ x 32’ steel shade structure and (4) 12’ x 12’ steel shade structures. See Drawings and Technical Specifications 10 73 46 for Prefabricated Steel Shelter. Measurement and payment shall be on a lump sum basis.

2. Contract Line Item No. 2: This item shall consist of:

Provide and install approximately 600 sf pad of stabilized decomposed granite for the large shade structure. Slopes on the pad may not exceed 2% running or cross slope.

Provide and install approximately 1200 sf of stabilized decomposed granite pathway connecting the new accessible picnic pad to the existing accessible parking space, portable toilet, drinking fountain, trail sign, trash/recycle containers, and concrete pad with viewing scopes. All new pathway paving shall meet federal ABA Accessibility Standards for Outdoor Recreation Access Routes (ORAR), including 5% maximum running slope on pathways and 2% maximum cross slopes. All edges of stabilized decomposed granite paving shall be contained by 4x6 redwood edging drilled and staked into the subgrade. Remove asphalt pad around drinking fountain and trash/recycle bins and reset them on new paving as needed. Note: the existing restroom is in the floodplain and its interior is not accessible, so the new decomposed granite pathway does not need to upgrade access to the building. See Drawings and Technical Specifications 32 15 43 for Stabilized Decomposed Granite Paving. Measurement and payment shall be on a lump sum basis.

3. Contract Line Item No. 3 (OPTION): This item shall consist of:

Provide and install (1) 8’ x 22’ steel shade structure at existing accessible bench area on the Prewett Point Trail. No new paving is included. See Drawings and Technical Specifications 10 73 46. Measurement and payment shall be on a lump sum basis.
