PROPOSAL FOR SUBSURFACE INVESTIGATION
PROPOSED SANITARY LANDFILL
WICHITA FALLS, TEXAS
Gentlemen:
We are pleased to submit this proposal for providing geotechnical engineering services
for your proposed landfill site. It is understood that the proposed 300-acre site is located near
the 600-acre site we investigated and reported on to you in January, 1980. It is understood
that approximately eight to ten feet of soil will be excavated from the bottom of the fill area
and used for a daily cover and a final cover for the site.
The site is within an area known as the Permian Formation. This formation consists of
interbedded sand, sandstone and clay. Although the Department of Health is the regulatory
agency which issues the permit for municipal landfill sites, it is worthy of note that this
formation is recognized by the Texas Department of Water Resources as being a suitable host
for waste disposal due to its low permeability characteristics.
We propose to investigate the site by drilling fifteen conveniently located borings in
the area to develop soil stratigraphy and profiles. Samples obtained in the borings will be
tested for plasticity characteristics and permeability. Based on the boring results, the suit-
ability of the site for a landfill will be evaluated.
The final report will contain the findings of the investigation, along with our
conclusions and recommendations regarding site preparation and other geotechnically related
design features.

Attention: Mr. Ernest Lillard 2. PN 650
Based on the scope of work outlined above, we have prepared the attached cost
estimate for providing the services. The estimated total cost is approximately $8,500,
and we suggest a total budget of $9,400 be appropriated for this work. You will be notified
if unforeseen subsurface conditions are encountered or there is a necessary change in the
scope of work. Additional work will not be performed withouf first obtaining your approval
of the additional costs. Any items of work not listed on the estimate will be invoiced in
accordance with our Standard Schedule of Fees, I, 11, and III, dated October 2, 1978.
Upon authorization to proceed, we can begin the work within one week and should
complete the project within approximately five weeks.
