Washburn University Board of Regents





SUBJECT: Gym South Soil Remediation



BACKGROUND:



The site is located at the south end of Moore Bowl in the confines of the University Storage Building #3, commonly known as Gym South. The site is the future location of the Student Recreation and Wellness Center and the proposed Art Building. Existing fill and possible fill soils extending to depths of 3 to 15 feet were encountered in many of the borings performed at the site. Based on results of laboratory tests, these materials did not appear to have been uniformly compacted to a high degree with moisture and density control. Building foundations supported on or above fill not uniformly compacted may not perform predictably and could potentially undergo greater-than-anticipated settlement due to the presence of unstable or unsuitable materials within the fill. Constructing foundations on fill materials such as those found was not recommended by the Geotechnical Engineer.



DESCRIPTION:



Subsequent to the initial soils testing, further subsurface exploration was conducted utilizing open test pits (under the direct supervision of the Geotechnical Engineer) to examine the constituency of the soil. Each pit was examined for the depth of fill and the depth to native soil and a total fill volume calculated. Based on known information, and recognizing a significant amount of unknown information existed, a remediation project was designed. Bids were received on the soil remediation project on Friday, February 21, 2003. These bids were as follows:



Singer Excavating $173,640

Berryton Excavating $327,699

Emcon, Inc. $411,715

Schmidtlein Excavating $219,080

Meier & Company, Inc. $285,745

Herrman's Excavating $127,720



The total pricing is based on unit price bids for each component of the project. Actual volume calculations will be made during the process of excavating the site, based on site surveys for quantity verification. The bid amounts presented above are based on calculated quantities of soil to be remediated provided in the request for bids. The final amount to be paid may vary slightly since it will be based on actual soil quantities removed, replaced, compacted, hauled off-site and disposed of, and replacement soils brought onto the site. The project currently assumes no hazardous or regulated wastes exist in the subsurface soil on the site. If during soil remediation, hazardous or controlled debris is found, Washburn will be required to pay additionally for the cleanup, hauling and disposal of the material to an approved landfill. The cost will be considerably higher if such circumstances are found.



FINANCIAL IMPLICATIONS:



The $127,720 for the remediation project to remove unsuitable construction soils, replace the soil adequately, and prepare the site for the construction of the Student Recreation and Wellness Center and the proposed Art Building is to be funded from the $11.2 million revenue bonds issued by Washburn University in December 2001.



The revenue bonds issued for the Student Recreation and Wellness Center and other projects will be repaid over a 20-year period from the $890,000 set aside annually in the Sales Tax Capital Improvement Fund.





RECOMMENDATION:



President Farley recommends the Board of Regents approve awarding a contract for remediation of unsuitable subsurface soils for construction purposes and site preparation to Herrman's Excavating in the amount of $127,720. If conditions during the project indicate hazardous conditions exists whereby a higher amount will be required to complete the project, work will be stopped and further consultation with the Board of Regents will be sought prior to proceeding.
