APPENDIX A AGI TECHNOLOGIES November 2, 1994 15,763.004.04 Mr. Dean Eckerson Contra Costa County Public Works Department 255 Glacier Drive Martinez, California 94553 Dear Mr. Eckerson: Scope of Services and Fee Estimate (Third Revision) Geotechnical Investigation San Pablo Dam Road Slide Repair (Station 252+00) Contra Costa County, California AGI Technologies (AGI) is pleased to present this scope of services and fee estimate (third revision) to perform geotechnical engineering services during investigation of the subject landslide. This scope and fee estimate is based upon information from the following sources: • Our discussions with Mr.Joe Yee and Mr. Dean Eckerson of the Contra Costa County Public Works Department (CCCPWD). • Review of the following correspondence regarding the site: - Geotechnical Engineering Study,Repair of Slide Damaged Shoulder,San Pablo Dam Road Station 250, Contra Costa County, California, dated February 2, 1984. - Evaluation of Alternate Schemes for Slope Repair, dated December 17, 1994 by Geospectra. - Geotechnical Consultation, dated May 31, 1994 by AGI. BACKGROUND The slide is located along San Pablo Dam Road about 2.5 miles north of the intersection of Bear Creek Road in Contra Costa County, California. The slide is located in an embankment fill slope below San Pablo Dam Road and above Old San Pablo Dam Road. The slope is inclined at about 827 Broadway,Suite 210 Oakland,California 94607 • (510)238-1590 • FAX(510)238-4599 WASHINGTON OREGON CALIFORNIA s APPENDIX A Oki Mr. Dean Eckerson Contra Costa County Public Works Department November 2, 1994 Page 2 1.1:1 (horizontal:vertical) and flatter. Erosion and slumping along the edge of the roadway have resulted in cracking of the asphaltic concrete pavement and surface settlement. The slide consists of a scarp up to about 20 feet high, with slide debris below. The slide area is covered with grass and brush. Surficial soils at the site consist of landslide debris and artificial fill. The area lies within an area interpreted to be a large landslide complex. The landslide debris from the large landslide complex is derived from deep seated failures in bedrock. Smaller secondary landslides, including the subject slide, exist within the large landslide. In the area containing the subject slide, San Pablo Dam Road is located on an artificial fill embankment up to about 20 feet deep, which in turn lies over the large landslide. In our May 31, 1994 letter, we discussed methods for mitigating the slide including a drilled pier and tieback wall, gravity retaining structure (crib wall, reinforced earth wall and soil nail wall), and a compacted fill buttress. Because it is impractical to repair the large landslide complex, all of the subject slide repair methods would be founded in the large landslide debris. Accordingly, they would be subject to movements of the large landslide complex. We understand you desire to mitigate the part of the slide that affects the roadway with a drilled pier and tie back retaining wall. The wall would be located between about Stations 251+80 and 253+60 along the east side of San Pablo Dam Road. PURPOSE AND SCOPE General The purpose of our services is to provide geotechnical design recommendations for a drilled pier and tie back retaining wall for the subject slide. Our scope of services consists of field exploration, geotechnical laboratory testing, engineering analyses, preparation of a written report and review of plans and specifications to be prepared by the CCCPWD, as outlined below. Field Exploration The more information is available regarding subsurface conditions at the site, the less risk there will be of change orders during construction. Costly change orders could result from deeper than anticipated pier lengths. Accordingly, we recommend drilling at least 3 test borings along the retaining wall alignment (at about the north end, center and south end) to identify the depth to supporting material so that the anticipated pier lengths can be determined. We also recommend that APPENDIX A AGI TECHNOlOG1E5 Mr. Dean Eckerson Contra Costa County Public Works Department November 2, 1994 Page 3 the CCCPWD mark the proposed retaining wall location in the field so that the borings can be accurately located. Less costly change orders could result from longer than anticipated tie back lengths. At the CCCPWD option, we could drill 1 to 3 test borings to determine the anticipated depth to supporting material in the area where the tie backs will be located. The more test borings are drilled in this area, the more accurate will be the anticipated depth to supporting material. If we are not requested to drill 1 or all of these test borings, we will assume a depth to supporting material based upon the results of surface observations and previous studies. Prior to field exploration, we will notify Underground Service Alert to identify underground utilities in the areas to be explored. We will apply for a drilling permit from the Contra Costa County Department of Health Services (CCCDHS). We assume the CCCPWD will obtain other permits and/or permission as necessary to perform the field exploration. We will explore subsurface conditions along the proposed retaining wall alignment with 3 test borings. The ground surface along the retaining wall alignment is relatively steep and inaccessible to conventional drill rigs. We will provide access by constructing a temporary roadway using a dozer. At the completion of drilling we will regrade the slope to allow surface drainage and apply hydroseed erosion protection. At the CCCPWD's option, we can also drill 1 to 3 borings along the area where the tiebacks will be supported. We understand that the CCCPWD desires that San Pablo Dam Road not be blocked by drilling operations. Accordingly, the test borings along the area where the tiebacks will be supported will be located within the west roadway shoulder. We will assume subsurface conditions beneath the roadway by interpolating between the conditions encountered within the borings. The borings will extend at least 20 feet below supporting material or to auger refusal (whichever is shallower). We anticipate the average boring depth will be 40 feet. Test borings will be drilled using truck-mounted, solid-flight or hollow-stem auger rig. Upon completion, the boreholes will be backfilled with grout as required by the CCCDHS. Soil samples from the borings will be collected using a split barrel sampler (2.4-inch inside diameter and 3.0-inch outside diameter) equipped with brass liner rings. The sampler will be driven 18 inches with a 140 pound hammer with a 30 inch drop. The sample will be driven less than 18 inches if the blow counts are greater than 50 per 6 inches. Blow counts will be recorded for the last 12 inches of each sample (or less if the sampler cannot be driven at least 12 inches). Blow counts will be recorded for the length of the sample. APPENDIX A AGI TECHNOLOGIES Mr. Dean Eckerson Contra Costa County Public Works Department November 2, 1994 Page 4 We will determine the test boring locations by taping from existing surface features and/or marked stakes. Elevations will be measured using a hand level from existing stakes in the ground of known elevation. The depth to the unstabilized groundwater level (if encountered) in the boreholes will be measured prior to backfilling. An experienced field geologist will coordinate all utility location, permitting, field exploration, placement of borings, and preparation of logs. Soil samples will be collected from the borings at 2.5- to 5-foot intervals and at changes in soil and rock conditions. Upon completion of site exploration, soil and rock samples will be transported to our laboratory for examination and selection of representative samples for testing. Geotechnical Laboratory Testing Geotechnical laboratory testing will be performed to assess pertinent physical characteristics of the materials encountered and to correlate them with those determined in previous investigations. We expect the testing program will include strength (triaxial and direct shear), classification (Atterberg Limits) and moisture/density. Analyses and Report Based upon the results of our subsurface exploration and laboratory testing, we will perform engineering analyses to develop detailed design and construction recommendations for the geotechnical aspects of the drilled pier with tieback retaining wall. Our analyses will also include evaluation of the lateral extent and depth of the existing slide to be repaired. We will work closely with the design team members during our services, and provide verbal conclusions and recommendations as they are developed. We will present results in a written report (draft and final), which will include: • Detailed description of the exploration and geotechnical laboratory test results. • Boring logs showing sampler size and type,soil descriptions,depth of strata, blow counts, and approximate boring and groundwater elevations. • Design recommendations for the drilled pier retaining wall including: - Depth to supporting material along the retaining wall alignment and estimated depth to supporting material along the tie backs - Lateral pressures due to soil, vehicles and seismic loads - Passive resistance of supporting materials - Tieback adhesion APPENDIX A AGI TECHNOLOGIES Mr. Dean Eckerson Contra Costa County Public Works Department November 2, 1994 Page 5 • Recommendations for slope inclination for temporary excavations that may be required for slide repair. • Recommendations for site preparation and grading including overexcavation and replacement criteria, and gradation and compaction criteria for on-site and imported soils. • Recommendations for surface and subsurface drainage related to the slide repair. • Comments regarding anticipated geotechnical-related construction problems and methods to mitigate such occurrences. The report will also include detailed construction recommendations covering drilled pier and tieback installation, and earthwork procedures. These recommendations will be presented in a form suitable for incorporation directly into project specifications. Plans and Specifications Review AGI will review the plans and specifications for conformance with the intent of the recommendations presented in our report. SCHEDULE We will schedule field investigation upon written authorization. We will provide verbal preliminary conclusions and recommendations after about 4 weeks. We will present the draft report about 6 weeks after authorization, and submit the final report about 1 week after receiving your comments. FEE ESTIMATE We propose the scope of services described herein be provided on a time and expense fee basis in accordance with our attached Schedule of Charges. Based upon our telephone conversation on October 19, 1994, you have elected to have AGI drill one test boring in the tie back area. For the scope of services described herein, we estimate our fee will be $19,472, including the cost of dozer and drill rig rental. We will not exceed these amounts without your prior written authorization. A fee estimate detail is attached. We suggest that you include a contingency of at least 20 percent of this amount for unanticipated conditions and services. We recommend that during construction we be retained to observe the subsurface conditions encountered. Our purpose would be to confirm the conditions upon which we based our geotechnical engineering recommendations, or revise our recommendations if different conditions APPENDIX A AGI TECHNOLOGIES Mr. Dean Eckerson Contra Costa County Public Works Department November 2, 1994 Page 6 are encountered. It is not possible to accurately estimate the costs for the geotechnical engineering services during construction at this time because the geotechnical investigation has not been performed, the retaining wall has not been designed, and the rate of construction is not known. We understand that you are budgeting $4,000 for geotechnical engineering services during construction. This amount may or may not be enough depending upon the actual conditions encountered during construction. If you are in agreement with the proposed scope of services and fee estimate, please issue a contract including the revisions we mutually agreed upon for County Project Numbers 0672-6R6529-93 and 0672-6R6530-93 dated February 11, 1994. If you have questions of comments regarding the proposed scope of services and fee estimate, please call. We look forward to providing services to you on this project.
