from 16.3% up to 24.3%. The fill was pumping and rutting as expected, but was able to support the construction equipment. On August 19' Dickerson proceeded to dry the material in-place by aerating it with a rotary mixer. On average, the moisture of the "select fill" dropped approximately 2% every day that it was aerated. On August 26, 1998, Dickerson stopped working on the test section. During the seven (7) day period, the soil was aerated for three (3) days. On the other four (4) days, no work was performed due to rain. The stockpiled "select fill' meets FDOT and ASSHTO requirements, but using the material has become an issue of constructability and keeping the project on schedule. Even though the "select fill" meets specifications, the clay fines seem to be retaining moisture. If the County allows the Contractor to haul in higher quality off-site materials, the project can stay on schedule and the completed roadway section will be stronger. The proposed off- site material has a high bearing ratio which eliminates the need to mix stabilize into the subgrade. Stabilization of the subgrade and excavation of the south college pond can be deleted from the contract. IRCC is agreeable to eliminating the south college pond because they have decided to expand the campus to the west. When the college is expanded, the County will extend College Lane west to 661' Avenue. At that time a pond will be excavated to provide stormwater retention for the college expansion and the roadway extension. The attached Change Order No. 2 in the amount of $175,150.67 includes increases for hauling in off-site borrow and deducts for eliminating the south college pond and stabilization of the subgrade. Revisions to the south college pond outfall, grading, sodding, and seeding and mulching the pond site are also included in this Change Order. RECOMMENDATIONS AND FUNDING Staff recommends approval of the attached Change Order No. 2 in the amount of $175,150.67. This added to the current contract amount of $6,014,307.03, results in a new contract amount of $6,189,457.70. Funding is from Account 109-214-541-067.31.
