ADDENDUM TO EXHIBIT B
Engineering Services
I. GENERAL
The objective of this Supplemental Agreement is to perform additional geotechnical services
related to development of Planning Level Engineering Reports and an Environmental
Assessment (EA) Supplement for the Phase 2 Deep Water Intake.
Specific services included in this Scope of Work are described herein:
II. SCOPE OF WORK
A. Additional geotechnical investigation will be performed to determine the soil conditions on
the Gross property in the area of the deep water cliff where the top intake screen will be
located. This investigation includes:
a. Perform one (1) boring drilled to a depth of about 50 feet each near the "cliff' close to the
lake.
b. Geotechnical laboratory testing will be performed on samples of bedrock to obtain
characteristics such as strength and hardness as it applies to tunnel and shaft
excavation technologies.
Prior to submitting samples to the laboratory for testing, Jacobs will submit a list of the
proposed laboratory tests for review and approval by (Client). The actual type and
quantity of laboratory tests will depend upon the material encountered and the sampling
method used. Laboratory tests and the standard to be used for testing may include, but
are not limited to, the tests listed below:
• Unconfined Compression -ASTM 02938
• Split Tensile Strength -ASTM D3967
• Mohs Hardness
c. Amend limited engineering report to include general subsurface conditions, boring logs,
stability recommendations for:
Allowable bearing pressures and provisions to resist uplift
• Excavation potential
• Drilled pier foundation for intake screen
B. Remove "Site Clearing" from original Scope of Work (2 days at $2,500 == $5,000).
