foundation recommendations for the proposed Composite Elevated Water Storage Tanks to be constructed
just southeast of the intersection of Nueces Bay Boulevard and West Broadway Street and just northwest
of the intersection of Flour Bluff Drive and Division Road in Corpus Christi,Texas.
Based on information provided to RETL,the project will include the construction of two new composite
elevated water storage tanks at the above locations. Additionally,the proposed project will include the
installation of a mat foundation to support an above-ground pipe support system at both sites. The
proposed mat is estimated to be on the order of 28-feet by 6-feet by 2-feet. The support system will
consist of four evenly spaced supports with an estimated maximum vertical load of approximately 6,000-
pounds per support. With this information,the engineers will require the maximum calculated total
potential vertical rise(PVR) for the specified structure at each site. Information regarding the proposed
structures is provided in the table below:

finished floor elevation.
• The client or representative of the client shall obtain the required access requirements, including right
of entry, and excavation permits, if applicable.
• The client shall perform due diligence to assure RETL that the boring locations are accessible and
clear of private utilities and obstructions, such as piping, fences, heavy brush, shrubs and trees. The
borings will be relocated if necessary.
• Coordination with the Texas 811 system will be performed by RETL to identify underground utilities
in the proximity of the boring locations. The borings will be relocated if necessary.
• An experienced soil technician will log the borings in the field full-time during the drilling operations.
• A truck mounted drilling rig will be utilized to access the boring locations to be performed.
• The borings will be sampled every 2.5-feet to a depth of 15-feet, and at 5-foot intervals thereafter to
the termination depth of the borings.
• Disturbed soil samples will be obtained employing split-barrel sampling procedures in general
accordance with the procedures for "Penetration Test and Split-Barrel Sampling of Soils, (ASTM
D1586)."
• Relatively undisturbed soil samples will be obtained using thin-wall tube sampling procedures in
accordance with"Thin Walled Tube Sampling of Soils, (ASTM D1587)," if applicable.
• Shear strength of cohesive soils will be estimated using a hand penetrometer, if applicable.
• Standard penetration tests (SPT) will be recorded in granular soils.
• The borings will be advanced to the depth specified above.
• GPS coordinates, obtained in the field at the boring locations, will be recorded using a commercially
available Garmin handheld GPS model Etrex Venture using NAD 83 map datum.
