Funds are budgeted in the Dublin Boulevard/Silvergate Drive Intersection Modification Capital Improvement Project for this purpose. DESCRIPTION: A project is included in the current Capital Improvement Program (CIP) which will modify the Dublin Boulevard/ Silvergate Drive intersection into a "T" intersection, with Dublin Boulevard being the through street. The first phase of design for this project is to obtain specialized geotechnical services. The data prepared under this agreement will be utilized by the design engineers to complete project plans and specifications. Dublin Boulevard is constructed on a fill embankment between Hansen Drive and Silvergate Drive. Numerous longitudinal cracks have developed on this section of Dublin Boulevard. Geotechnical investigation is needed to assess the subsurface condition beneath the pavement in order to determine the reason for the cause of distress and to recommend mitigation. The investigation will also include recommendations for fill materials, compaction requirements, cut and fill slope stability considerations, pavement design parameters, and alternative pavement sections for the added lanes and possible replacement of existing pavement. On July 24, 1991, the Public Works Department received four (4) proposals from local qualified engineering consulting firms. After reviewing all four proposals for past performance, experience, knowledge of the area and site, ability to complete the project in a short time, and equipment and staffing, Staff considered Berlogar Geotechnical Consultants best able to fulfill the City's requirements. After choosing Berlogar as the consultant, Staff opened the fee proposal packages and found Berlogar's fees to be in line with the scope of work to be performed. In accordance with State Law, the selection of engineers and architects and other specified services must be based upon qualifications rather than bid prices. Staff will have an item on a future agenda regarding the selection of an engineering design firm to prepare plans and specifications for this project. The geotechnical services will result in recommendations which will be incorporated into the final design. DUe to the specialized nature of geotechnical services, it is typical to utilize two different consultants for this type of work. staff recommends that the City Council adopt the resolution approving the agreement with Berlogar Geotechnical Consultants.

Box 2340 Dublin, California 94568 Subject: Proposal Geotechnical Investigation Dublin Boulevard Between Hansen Drive and Silvergate Drive Dublin, California_ Dear Mr. Thompson: We are pleased to present this proposal to perform a geotechnical investigation for the subject site. This proposal is in response to your ,,Request for Proposal" (RFP) letter submitted to our office. We previously submitted a proposal to perform a pavement distress investigation for Dublin Boulevard, dated November 5, 1989. According to your "RFP" Dublin Boulevard will be widened between Hansen Drive and approximately 400 feet west of Silvergate Drive and the intersection with Silvergate Drive will be reconstructed. The existing road is about 15 to 20 years old and is constructed on a fill embankment ranging in height from about 5 to 25 feet. During a visit to the site prior to the preparation of our initial proposal letter, we observed numerous longitudinal cracks in the pavement with most of the cracks on the northern side of the east-west trending roadway. At that time, you informed us that these cracks had been present for several years and had increased since they were sealed in May 1989. During a recent visit to the site, we noted the cracking patterns are still present and appear to have increased since our previous site visit. The purpose of our geotechnical investigation would be to assess the subsurface conditions beneath the pavement in order to determine the cause of distress and to provide recommendations for mitigation and repair. It shall also include the preparation of recommendations for the roadway widening including recommendations for fill materials, compaction requirements, cut and fill slope stability considerations, pavement design for the added lanes and recommendations for possible replacement of the existing pavemen%. Our initial observations and our experience with other projects in the area suggest that the pavement distress may be caused by shrinking and swelling of the expansive embankment soils. The shrinking (from drying) of the expansive embankment soils may be influenced by the large trees located along the slopes on both sides of the roadway. Root systems from large trees can remove significant amounts of moisture from the surrounding soil resulting in shrinking of the surrounding soils and subsequent depressions SOIL ENGINEERS ' ENGINEERING GEOLOGISTS ' 5587 SUNOL BOLILEVARD ' PLEAS/' Page 2 July 24, 1991 Job No. 7992.400 or cracking in the overlying pavement. We have observed the phenomenon in other parts of the Livermore Valley and are currently performing investigations on two nearby sites where this phenomenon has resulted in major distress to pavement areas. It is also possible that slope failure related to creep or seismic affects may be at least a contributing cause to the observed distress. SCOPE OF WORK The scope of our investigation will follow the outlined tasks presented in your RFP. ~ask 1 We will perform a reconnaissance of the site and review the available reports, drawings and maps related to the project. Task 2 We will perform a field investigation which will include the drilling a total of five borings within the roadway area. Three of the borings will be drilled in the area of pavement cracking to depths ranging from 20 to 35 feet below existing grade. The other borings will be drilled to depths of 10 feet in the area of proposed widening. The borings would be drilled under the supervision of our field engineer who would prepare detailed logs of the materials encountered and obtain both bulk and relatively undisturbed samples of the earth materials for laboratory testing. The bore holes will be backfilled with soil cuttings and capped with asphalt patch. Task 3 We will perform laboratory testing on selected soil samples which will include moisture content and dry unit weight determinations, Atterberg Limits and shrink-swell tests to evaluate the expansion potential of the existing fill soils, and static strength test to evaluate slope stability characteristics of the subsurface materials. We will also perform R-value tests on the existing subgrade soils for design of the proposed new roadway section. Task 4 After we have completed our field and laboratory testing we will analyze the data and meet with your staff to discuss the findings. Task 5 We will prepare a written report presenting our findings along with conclusions and recommendations. Our report will include: BE~RLOGAR GEOTECHNICAL CONSULTANTS Page 3 July 24, 1991 Job No. 7992.400 1. A description of the subsurface conditions including the content and thickness of the existing fill. 2. Our opinions regarding the causes of the existing pavement distress and recommended mitigation measures. 3. Recommendations for construction of the widened roadway including: recommended excavation and subgrade preparation; cut and fill slopes; surface and subsurface drainage; fill materials; compaction requirements; slope stability considerations; alternative pavement sections and possible replacement of the existing pavement; and necessary precautions for slopes during construction. 4. Design parameters for retaining structures for the new embankment, if necessary. 5. A general description of geologic hazards including seismic considerations. Our work will be performed by our qualified staff of professionals and technicians under the supervision of Mr. Dan O'Connell, principal engineer, a registered civil engineer in the State of California. We will submit ten (10) copies of our final report to the city of Dublin. We are prepared to begin our site reconnaissance services immediately upon authorization. We expect to be able to perform our field investigation within one to two weeks after authorization, depending on availability of a subcontracted drill rig. We expect that our laboratory testing would be completed within one week after completion of our field investigation and we would be available to meet with the city to discuss our findings within two weeks. We would complete our written report within one week after meeting with your staff. our firm has provided geotechnical services for the city of Dublin and other clients on numerous projects in the site vicinity. For the city of Dublin, we recently provided consultation regarding pavement distress on Juarez Court and performed a geotechnical investigation for improvements to Shannon Park. We are on the project team providing consultation to the city for the West Dublin Study Area which is located due west of the subject project. We have also provided consultation to the major property owner in the East Dublin Planning Area.

GEOTECHNICAL AND SOILS INVESTIGATION FOR DUBLIN BOULEVARD BETWEEN HANSEN DRIVE AND APPROXIMATELY 400' WEST OF SILVERGATE DRIVE The City of Dublin invites Submittals of Proposals to perform and prepare reports for geotechnic~l and soils investigation for Dublin Blvd. between Hansen Drive and approximately 400' west of Silvergate Drive. Backqround Currently, Dublin Blvd. west of Silvergate is a two-lane street that ends in a cul de sac west of Silvergate Drive with few residences and businesses. Most of the traffic travels between Dublin Blvd. east of Sitvergate Drive and Silvergate Drive. This pattern will change in the future due to development west of Silvergate Drive close to Dublin Blvd. and the extension of Dublin Blvd. further west with interchanges to the 1-580 freeway. The expected increase in traffic on Dublin Blvd. makes it necessary to widen Dublin Blvd. and modify its intersection with Silvergate Drive. Dublin Blvd. is constructed on a fill embankment between Hansen Drive and Silvergate Drive. Numerous longitudinal cracks can be seen on this section of Dublin Blvd. Geotechnical Investigation shall include assessing the subsurface condition beneath the pavement in order to determine the reason for the cause of distress and recommending mitigation for it. It shall also include providing recommendations for fill materials, compaction requirements, cut and fill slope stability considerations, subgrade R-value(s), and alternate pavement sections for the added lanes and possible replacement of the existing pavement. Scope of Work The Consultant's work scope shall include the tasks outlined below: TASK I. Perform a site reconnaissance and review existing geotech- nical reports, construction drawings, aerial photographs, topographic maps, and pertinent documents in order to assess the conditions prior to construction and the manner in which the existing two-lane section of Dublin Blvd. (between Hansen Drive and Silvergate Drive) was constructed. x-.:r- '- s:'a',c~' ¢z'E $33 665'.0 ' C~t',~ Ccunc~!
