REQUEST FOR PROPOSALS

Project Name: Geotechnical Engineering Services for New Water Storage Tank IHS Project 20-W38

Project Location: 69501 E. 85 Rd, Wyandotte, Oklahoma (Ottawa County)

1. Project Description and Scope of Services

A. The Indian Health Service (IHS) is seeking geotechnical engineering services for the design and construction of a new approximately 120,000 gallon, 100-foot tall, 26-foot diameter elevated water storage tank for the Ottawa County Rural Water District #5 in Ottawa County, Oklahoma. The new water storage tank will be located adjacent to the District’s existing water storage tank and is anticipated to be of standpipe design (i.e., singular, cylindrical center column). It is estimated that construction of the new water storage tank will occur in the 2025 construction season.

B. The existing water storage tank is located approximately half a mile east of the

Intersection of E 85 Rd and South 690 Rd and is near the Town of Peoria, Oklahoma.

The project site is immediately west of the existing water storage tank. Possible existing utilities, including an active water main that connects to the existing tank, are near the proposed project site. See Exhibits A and B.

C. Site access will be made available for completion of field activities, as required. Field activities shall not commence until approval by IHS and the Ottawa County Rural Water District #5 is granted.

D. The Scope of Services includes field services, laboratory services, and professional services as follows:

1) Determination of the subsurface conditions at the project site.

2) Evaluation of the subsurface conditions with respect to the proposed construction.

3) Recommendation for foundation design.

4) Conformance to Oklahoma Department of Environmental Quality Title 252 Chapter

626 for public water supply construction standards.

5) Conformance to AWWA D100-11 for welded carbon steel tanks for water storage.

6) Conformance to ASTM D1586 and D1587 for drilling and sampling.

2. Format Requirements

A. Submit deliverables electronically via email in PDF format.

B. Submit deliverables to the Project Engineer at:

Steven Boyd, E.I.T.

Indian Health Service P.O. Box 510 Miami, OK 74354

Tel: (918) 542-6637 Email: Steven.Boyd2@ihs.gov

3. Tasks

A. The Contractor shall be responsible for all fees, work, labor, laboratory testing and analysis, materials, mileage, travel expenses, and permits and accepts all liability for the services to be performed. The Contractor shall notify the IHS Project Engineer and the Ottawa County Rural Water District a minimum of 48 hours before commencing field work.

B. It shall be the responsibility of the Contractor to visit the project site and make his/her own determination of field conditions.

C. The Contractor shall drill a maximum of three (3) borings, unless otherwise approved in writing by the IHS Contracting Officer.

4. Deliverables

A. Geotechnical Engineering Report signed and sealed by a Licensed Professional Engineer in the State of Oklahoma.

1) The geotechnical engineering report shall include the following minimum information:

a. Detailed boring logs complete with blow count records.

b. Record of any undisturbed samples.

c. Laboratory analysis of samples.

d. Stability and estimate of total and differential settlement.

e. Water level in boring holes at time of drilling and before site is left.

f. Site topography and elevation of borings including exact location of borings.

g. Tank foundation system(s) recommendation.

h. Information as to whether allowable bearing values can be increased for wind, earthquake, or other temporary loadings including factor of safety for bearing values stated.

i. Bearing capacity of the soil, factor of safety used in obtaining bearing capacity, and depth at which footings (if required) must be founded.

j. Seismic design considerations.

k. Temporary construction considerations and concerns.

l. Soil material and compaction requirements for support of the tank.

m. Reusability of on-site soils in compacted fills.

n. Frost penetration depth and effect.

o. Site geology.

5. Proposals

A. Include in the proposal:

1) Anticipated number and depth of borings.

2) Type of drilling rig to be used.

3) Schedule.

4) Detailed breakdown of fees for field services, laboratory services, and professional services.
