ADA/ABA-compliant pathways.

K. Location: Painted Rocks Campground worksite is located at longitude N 33.022813 decimal degrees, latitude W 113.047347 decimal degrees referenced to North American Datum 1983 that is used throughout these specifications. The worksite by local roads is about 31 miles west of Gila Bend, Arizona. From Gila Bend, take Interstate 8 West and exit on Exit 102 “Painted Rock Road” for about 9 miles and continue straight onto Rock Point Road for about 0.5 miles arriving at the entrance to Painted Rocks Campground at N 33.024354 in decimal degrees, W 113.045356 in decimal degrees. Note that this road has inconsistent names that can be Painted Rock Dam Road and Citrus Valley Road. In the Public Land Survey System, it is Township 5S, Range 08W, Section 02. The worksite area can be described as generally flat with rock outcroppings with surrounding mountains and washes throughout in a desert climate.

L. Climate: Nearby Gila Bend, Arizona, gets 7 inches of rain, on average, per year. The US average is 38 inches of rain per year. Gila Bend averages 0 inches of snow per year. The US average is 28 inches of snow per year. On average, there are 296 sunny days per year in Gila Bend. The US average is 205 sunny days. Gila Bend gets precipitation, on average, 25 days per year.

Precipitation is rain, snow, sleet, or hail that falls to the ground. In order for precipitation to be counted, the location has to get at least 0.01 inches on the ground to measure. The annual BestPlaces Comfort Index for Gila Bend is 7.2 (10 = best), which means it is less comfortable than most places in Arizona. Monsoons happen during the summer, which the official dates are from 15 June to 30 September. Flash flooding can occur anytime during the year.

M. Camping on Site: Camping on BLM land is allowed in accordance with the work camp

Guidelines attached to this Contract. Nearby lodging is about 31 miles away in Gila Bend.

Final camp locations will be field approved by the COR/PI.

PART 1 - GENERAL

1.1 SUMMARY

A. Description of Work: Excavation is primarily for placement of concrete forms “and/or” concrete placements, backfill of materials wherever necessary, and execution of other earthwork activities as necessary.

1.2 REFERENCE DRAWINGS

A. Refer to the attached Specifications Drawings.

1.3 DEFINITIONS & LIMITATIONS

A. ABC is an acronym for aggregate base course and is composed of natural or crushed, angular rock and some fines. It is of varying sizes that meet the gradation standards in this Section and is used as a base course in roadways, pathways, and concrete pads as well as for foundations in general. It is also used as a backfill material for general fill situations, underground pipelines, and other underground utilities.

B. Backfill is concrete, controlled low-strength concrete or aggregate base course (ABC).

Native material from excavation is generally considered an unclassified excavation that is subject to the COR/PI’s discretion for use. It furthermore must be free of loose materials like vegetation and deleterious materials. Refer to unclassified excavation.

C. Unclassified Excavation is earthwork on native material of unknown soil classification under a classification system that is recognized, say, in Geotechnical Engineering. The materials may include rock, soil materials, and obstructions.

D. Earthfill is earthwork on native or local soil without vegetation and other deleterious material resulting from excavation for concrete work or nearby on site. Otherwise, any earthfill source shall require the approval of the COR/PI before use.

E. Excavation is the removal of material encountered on surface and are:
