STRUCTURES: As requested, perform a total of eight (8) Standard Penetration Test (SPT) borings within the foot print of the proposed building structures to a depth of 30 feet below grade.
PARKING AND STORAGE AREAS: As requested, perform a total of thirty-five (35) hand auger borings to a depth of 5 feet below grade. It is anticipated that 18 of the 35 borings will be performed through existing pavement and will require a pavement core.
PONDS: As requested, perform four (4) field permeability tests with associated SPT borings (one per pond) to a depth of 20 feet.
Visually classify the samples in the laboratory using the Unified Soil Classification System (USCS). Perform laboratory classification tests to confirm the visual classifications. Identify soil conditions at each boring location.
Obtain bulk soil samples and perform ten (10) California Bearing Ratio (CBR) tests on selected samples collected from within the proposed paved areas.
Prepare a formal engineering report that summarizes the course of study pursued, the field and laboratory data generated, subsurface conditions encountered and our engineering recommendations in each of the pertinent topic areas.
This proposal is based on the work being performed in accordance with the attached Tierra, Inc. Unit Fee Schedule. For the above scope our estimated fee is $29,561.26.
The proposal is based on the following assumptions:
No hazardous materials exist on-site that would impact our investigation.
Location of existing subsurface utilities is to be performed by others prior to commencing field activities.
The site is readily accessible and Tierra is able to perform the work within normal business hours and access will be pre-arranged.
