(PSI), an Intertek company, is pleased to submit this proposal to conduct a geotechnical exploration at the above referenced property. PSI thanks you for the opportunity to propose these geotechnical services and looks forward to being part of the design team. This work involves reconstruction of Long Meadow Drive from Hunt Drive to St. Andrews Drive (approximately 4,000 lineal feet) in Corpus Christi, Texas. A review of project information, along with a proposed scope of services, schedule and fee information is provided below. Project Understanding Project information was provided by Ms. Marisa Alaniz, EIT with the City of Corpus Christi: The geotechnical exploration will be performed for street design per City of Corpus Christi req uirements. PSI understands it is desired for this street to be a 30-year pavement design for both HMAC (with multiple options) and concrete street and sidewalk including subgrade compaction requirements. PSI also understands the City of Corpus Christi will provide design traffic information that PSI will utilize to determine appropriate design traffic ESALs and resulting potential pavement section options. The design will include 1 option consisting of a flexible pavement section having a thickness of 7.5 inches.We will evaluate the potential of recycling the existing pavement materials into the new pavement section options. PSI will initially submit an unsealed draft report for City and Consultant to review along with a preliminary invoice. Should the above information or assumptions be inconsistent with planned construction, the Client should contact the PSI office and allow necessary modifications to be made to the proposal. Exhibit A 0 Page 1 of 9 Proposed Long Meadow Drive Reconstruction(Hunt Dr to St Andrews Dr) PSI Proposal No. 273542 Corpus Christi, Texas April 24, 2019 SCOPE OF SERVICES The geotechnical engineering scope of services will include the following items. • Field exploration consisting of drilling and sampling of the subsurface materials and observing groundwater levels at the site. • Laboratory testing of the subsurface materials. • Performing engineering analyses and providing geotechnical recommendations in a geotechnical report. Field Exploration We propose a total of 10 borings for this project. Five (5) of the borings will be drilled to a depth of 5 feet for pavement design and 5 borings will be drilled to the 25-foot depth for utility and signal design purposes. The table below summarizes the planned exploratory boring program. Summary of Borings Design Element Number of Boring Depth(s) Drilling Footage Borings (feet) (feet) Pavement Design 5 5 25 Signals and Utilities Design 5 25 125 TOTAL 10 - - 150 The borings locations will be identified in the field using GPS coordinates using a hand-held GPS device. Approximate GPS coordinates for the boring locations will be obtained from the Google Earth computer program. Surveying of the boring locations to obtain surface coordinates and elevations is beyond the scope of work and should be surveyed by others prior to construction. References to elevations of various subsurface strata will be based on depths below existing grade at the time of drilling. • During the field activities, the subsurface conditions will be observed, logged, and visually classified field notes were maintained to summarize soil types and descriptions, water levels, changes in subsurface conditions, and drilling conditions • Final depths of the borings may be extended or reduced depending on the subsurface materials identified during field activities. • PSI will contact Texas One Call/Dig Tess, etc. or other public utility clearance companies prior to the start of drilling activities. It is our experience that these companies do not mark the locations of privately owned utilities. This proposal is based on private utility lines and other subsurface appurtenances are located in the field by others prior to field activities. • Some damage to the ground surface may result from the drilling operations near the work areas and along ingress/egress pathways. The field crew will attempt to limit such damage, but no restoration other than backfilling the borings is included in this proposal. Excess auger cuttings and drilling spoils will be collected and disposed of offsite. • PSI will exercise reasonable caution to avoid damages to underground utilities by contacting local utility companies prior to the field activities. However, private utility locations are often unknown by public utility companies and by the utility owners. Therefore, PSI will not be responsible for damage to the site or any buried utilities that are Page 2 of 10 Exhibit A Page 2 of 9 Proposed Long Meadow Drive Reconstruction(Hunt Dr to St Andrews Dr) PSI Proposal No. 273542 Corpus Christi, Texas April 24, 2019 not made known to us. • PSI will provide traffic control during drilling and sampling operations Field Exploration Description Drilling Equipment Truck-Mounted Drilling Equipment Drilling Method Continuous-Flight Auguring, Mud Rotary Drilling Procedure Applicable ASTM and PSI Safety Manual Field Testing Hand Penetrometer, Split Spoon Testing (ASTM D1586) Sampling Procedure Soils: ASTM D1587/1586 Sampling Frequency Continuously to a Depth of 10 Feet and 5 feet thereafter During, After Drilling and Delayed for the Utility Frequency of Groundwater Level Measurements Borings; During and After Drilling for the Pavement Borings Boring Backfill Procedures Soil Cuttings and Asphalt Patch Sample Preservation and Transportation Procedure General Accordance with ASTM D4220 Laboratory Testing Representative soil samples obtained during the field exploration program will be transported to the PSI laboratory for testing. The nature and extent of this laboratory testing program will be dependent upon the subsurface conditions identified during the field exploration program. The laboratory testing program on selected samples may include moisture content tests, Atterberg limits tests, sieve analyses, and other tests as required to identify the engineering characteristics of the subsurface materials. Engineering Analyses and Report The results of the field exploration and laboratory testing will be used in the engineering analysis and in the formulation of the recommendations. The results of the subsurface exploration, including the recommendations and the data on which they are based, will be presented in a written geotechnical report. The geotechnical report includes the following items: ➢ Boring Location Plan (Map of Boring Locations) ➢ Existing soil characteristics along route. ➢ Water table depth along route. ➢ Fill material recommendations with and without existing road bed. ➢ Recommendations and considerations for fill and compaction methods in high water table areas, and in poor underlying soil areas, if any. ➢ Recommendations on how to mitigate roadway settlement, if any, due to fill overburden, loads during construction, and operational loads after completion. ➢ Trench excavation design parameters ➢ OSHA soil type classification Page 3 of 10 Exhibit A Page 3 of 9 • Proposed Long Meadow Drive Reconstruction(Hunt Dr to St Andrews Dr) PSI Proposal No. 273542 Corpus Christi, Texas April 24, 2019 ➢ Traffic counts ➢ % growth over pavement life ➢ Design vehicles ➢ Design trucks ➢ Roadway pavement and shoulder design section recommendations will be provided to include soil amendment alternatives, geogrid and geotextiles alternatives, flexible pavement, and rigid pavement. Section recommendations based on average vehicle trips per day and projected traffic growth for 30 years to be provided by the City, with an appropriate ESAL calculated from the provided traffic count data. Multiple feasible pavement options will be included. A min. 2.5 Serviceability Terminal Index will be utilized. No bond breaker will be utilized for asphalt pavements ➢ Discussion of utilizing a TX-5 geogrid as an acceptable alternative to lime stabilization ➢ Narrative of benefits/risks of proposed components ➢ Recommendation for prolonging pavement life and protecting the pavement section during construction will be included ➢ If proposed flexible pavement section exceeds 7.5 inches of HMAC, 1 equivalent pavement section shall include 7.5 inches HMAC. ➢ For thick pavement sections, alternative section reduction options will be included such as multiple grid option, increased asphalt thickness,etc. ➢ Construction testing recommendations. Interaction with the City PM will be made and a draft report for review will be submitted prior to report finalization. An alternative to providing multiple pavement options for each set of material components would be to discuss recommended sections with the City and AE for review and approval to determine desired options to be included in the report. A pdf version of the geotechnical report will be prepared and submitted by email to the Client and design team. If requested by the Client, additional hard copies can be provided. The geotechnical report will be reviewed, signed, and sealed by a registered Professional Engineer. SCHEDULE Based on the site being accessible to the truck rig, drilling can commence within approximately one week after receipt of authorization to proceed, weather permitting. Preliminary verbal recommendations could be made available after laboratory testing is completed. A final report can be provided within 5 weeks of authorization. Delays sometime occur due to adverse weather, utility clearance requirements, site clearing requirements for drill rig access, obtaining drilling permits, obtaining Right of Entries and other factors outside of PSI's control. In this event, PSI will communicate the nature of the delay and provide a revised schedule at the earliest possible date. E PSI proposes a fee of$18,495.00 to perform the above outlined services.
