(PSI) 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 Lipes Road from Yorktown Blvd. to Sunwood Drive 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 requirements. Based on the CH2M scope document provided, the proposed project will include the reconstruction of the existing 2-lane roadway with shoulders. New utility lines will be installed approximately 10 to 20 feet below finished pavement. No new traffic signals or illumination will be included as part of this project. The geotechnical Scope of Work will include evaluating the subsurface soils within the limits of the proposed roadway reconstruction project by obtaining information on the in- situ soils and groundwater conditions and to provide both flexible and rigid pavement sections suitable for 30-year pavement designs. Pavement design options will include pavement sections utilizing new materials with/without treated subgrade. PSI will also provide recommendations on the suitability of recycling the existing asphaltic concrete for possible use as base material for either a flexible or rigid pavement. Pavement design options using recycled asphalt base material will be provided if the existing asphaltic concrete is suitable. PSI will provide recommendations for the use of either reinforced concrete or HMAC pavement and the suitability for each option. PSI will also soil parameters, trench excavation design parameters, OSHA soil type classification and recommendations needed by the contractor/engineer to design braced excavations for installation of underground utilities. Exhibit A Page 1 of 6 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. 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 Based on the CH2M scope document, a total of 7 soil borings are proposed for this project at the approximate locations shown on the attached Boring Location Plan. The table below summarizes the planned exploratory boring program. Summar of Borin.s Boring Purpose Number of Boring Depth(s) Drilling Footage Borings (feet) (feet) Roadway Design, Utilities 3 25 75 Roadway Design 4 6 24 TOTAL 7 --- 99 The borings locations will be identified in the field using available natural landmarks or GPS coordinates.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 off-site. • PSI will exercise reasonable caution to avoid damages to underground utilities by contacting local utility companies prior to the field activities. However, private utility Exhibit A Page 2 of 6 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 not made known to us.

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 will include the following items: ➢ A description of the field exploration and laboratory tests; ➢ Boring logs; • A discussion of the engineering properties of the subsurface materials encountered; ➢ Groundwater readings; Trench excavation design parameters; • OSHA soil type classification; ➢ Utility trench recommendations and pavement recommendations for the proposed project utilizing the following information provided by the City: Exhibit A Page 3 of 6 ❖ Traffic Counts ❖ Projected Percent Growth of Traffic Over Life of Pavement ❖ Design Vehicles ❖ Percent Trucks; D Calculated 30-Year ESALs, including assumptions, based upon traffic data provided by the City. 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 4 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. FEE PSI proposes a fee of$10,988.00 to perform the above outlined services. PSI proposes the fee for performance of the outlined scope of services be charged on a unit rate basis based upon PSI's 2018/2019 Master Service Agreement for Geotechnical and Materials Testing (17099A) for the project no. shown on the attached Estimated Fee Breakdown.

PSI will exercise reasonable caution to avoid damages to underground utilities by contacting local utility companies prior to the field activities. However, utility locations on the owners'side of the meter are often unknown by utility companies and by the utility owners. Therefore, PSI will not be responsible for damage to any buried utilities that are not made known to us.
