DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The project site is a two-level single-family home located near Limantour Beach in Point Reyes National Seashore. The residence was constructed circa 1962. Two relatively level pads were graded into the original sloping terrain. The home consists of a main living space on the upper level constructed over a partial basement and garage on the lower level. The upper pad is roughly ten feet above the lower pad. The lower-level partial basement and garage are constructed on a concrete-slab-on-grade. Half of the upper level is on wood frame over the lower level, while the balance is atop a shallow spread footing of unknown dimensions.

A geotechnical and structural analysis was conducted in 2013 due to extensive slab cracking and settlement [reference report included as Attachment I]. The shallow spread footing and slab were identified to be on top of a relatively thin layer (5-9 ft thickness) of weak, poorly compacted, sandy soil that has been subject to slow ongoing settlement. It is expected that slow settlement will continue unless foundation stabilization is undertaken.

This project addresses recommendations for foundational stabilization contained in the 2013 Miller Pacific geotechnical and structural analysis along with other residential rehabilitation items described herein.

The project residence is used for housing park employees. The residence will be vacated and unoccupied during the contract work.

Reyes National Seashore. The site is roughly seven miles west of Point Reyes Station, CA at latitude/longitude 38.027080, -122.876278.
