(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 Laguna Shores Road from Caribbean Drive to Hustlin Hornet Drive(approximately 5,000 If) 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. We understand that 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. We understand that the City of Corpus Christi will provide design traffic information that we will utilize to determine appropriate design traffic ESALs and resulting potential pavement section options. We also understand that the roadway design will include retaining walls and culverts. 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.

Field Exploration Based on the Laguna Shores Scope of Services document from Mr. Jeffrey C. Coym, P.E.with LJA Engineering dated August 13, 2018, a total of 22 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. Summary of Borings Location Number of Boring Depth(s) Drilling Footage Borings (feet) (feet) Within Road Pavement 11 10* 110 On Road Shoulder 11 20* 220 TOTAL 22 --- 330 *Depending on the subsurface and conditions encountered, borings may need to be deeper in those areas where retaining wall embankments will be constructed since potential settlement magnitude from fill placement and retaining wall design information such as bearing capacity,sliding and global stability will need to be evaluated. 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 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 not made known to us.

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, unconfined compressive strength tests, 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 may include the following items: 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. Erosion protection recommendations for non-contained fill alternative. Retaining wall design parameters for contained fill alternative. Subgrade preparation recommendations for box/circular culverts.

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 for a minor collector roadway. Construction testing recommendations. 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. SPECIAL GEOTECHNICAL DESIGN CONSIDERATIONS Pavement performance at this location is affected by other factors that would typically not be a design consideration for normal pavement design projects in Corpus Christi. For example, this area is subject to periodic inundation from tidal and storm surges which can detrimentally affect the performance of the subgrade, base and surface pavement materials. Fill embankments and retaining walls may be subject to excessive settlement or have inadequate bearing capacity which may lead to the requirements for ground improvements depending on the height of the fill and the consolidation characteristics of the underlying subgrade. We will need to initially meet with the project team and discuss the planned grading along the route so that appropriate adjustments to the number and depth of borings could be made if needed. 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. FEE PSI proposes a fee of$26,650.00 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) shown on the attached Estimated Fee Breakdown. //ASI Exhibit �/�� Page 4 of 10 • Laguna Shores from Caribbean Drive to Hustlin Hornet Drive October 1, 2018 Corpus Christi, Texas PSI Proposal No. 255101 Page 5 of 10 ESTIMATED FEE BREAKDOWN Laguna Shores Rd. from Caribbean Drive to Hustlin Hornet Drive (Project No. 18024A) Item Field Units Unit Quantity Extension Rate 1 Staking/Coordinating (Sr. Tech) hrs 45.00 8 360.00 2 Mobilization of Drill Rig ea 350.00 1 350.00 3 Traffic Control day 1,800.00 3 5,400.00 4 Drilling and Sampling (0-50') plf 16.00 330 5,280.00 5 Bentonite/Asphalt Patch plf 6.00 330 1,980.00 Subtotal: $13,370.00 Laboratory 1 Moisture Content ea 6.00 110 660.00 2 -#200 Sieve Test ea 50.00 30 1,500.00 3 Atterberg Limits ea 60.00 30 1,800.00 4 Consolidation Test ea 950.00 2 1,900.00 5 Sulfate Tests ea 95.00 5 475.00 Subtotal: $6,335.00 Engineering 1 Project Manager hrs 100.00 6 600.00 2 Project Engineer hrs 125.00 25 3,125.00 3 Principle Consultant Review hrs 175.00 16 2,800.00 4 Drafting/CADD hrs 75.00 4 300.00 5 Admin hrs 60.00 2 120.00 Subtotal: $6,945.00 TOTAL CALCULATED FEE: $26,650.00 The proposed fee covers the work needed to provide a report presenting the geotechnical findings and recommendations.
