LAKESHORE DRIVE • OCOEE, FLORIDA 34761 PHONE (407) 656-2322 EXT. 142 • FAX (407) 656-7835 MEMORANDUM DATE: May 13, 1996 TO: The Honorable Mayor and Board of City Commissioners FROM: James W. Shira, P./sD/irector City Engineer/Utilit SUBJECT: Addendum No. 96-01 Geotechnical Services Contract with PSI Attached for your review is a proposed Addendum to the continuing contract with PSI. In order to determine the character of- the sub -surface soils in the area of the existing rapid infiltration basins at the golf course, PSI proposes to perform the work outlined in their letter dated April 18, -1996. With the information derived from these tests, we will be able to estimate the effluent disposal capacity of the site more accurately. I recommend that the City Commission authorize the Mayor and City Clerk to execute Addendum No. 96-01 inthe not -to -exceed amount of $2,900.00. - JWS/jbw Attachment THE PRIDE OF WEST ORANGE A M r�;:� f EOn0ilt; a' Cae0tech99it;'ai C'onstrMction Consulking • Engineering s Testing April 18,' 1996 The City of Ocoee 150 N. Lakeshore Drive Ocoee, Florida 34761 Attention: Mr. Jim Shira, P.E. City Engineer/Director Utilities RE: Additional Soil Borings RIB Site Evaluation Forest Lakes Golf Course Project No. 757-55049 Dear Jim: Pursuant to our recent meeting, PSI is pleased to present our proposal for performing a series of standard penetration test borings within the RIBS at Forest Lake Golf Course. The primary purpose of performing these additional soil borings is to determine if a cemented, hardpan type or dense soil layer exists within the upper 25 feet of the bottom of the RIBS that could be a potential cause of the seepage which is occurring into the adjacent sinkhole area and over the 13th green. We have proposed performing six, 25 feet deep standard penetration test borings as discussed in our recent meeting, spread out over the RIB areas. Review of previous soil borings performed by others during the design phase of the RIBS suggests that a hardpan or cemented type layer may occur in the northern RIB, but only actual soil borings with continuous blow counts can give us a true indication of the density or potential impermeable conditions of the existing subsoils. We estimate our cost to mobilize, do boring layouts and then perform the six, 25 foot deep standard penetration test borings and prepare a brief engineering report of our findings and evaluation to not exceed $2,900.00. The attached Appendix shows a breakdown of our scope of services and corresponding fees. Time wise, we are in a position to perform the soil borings within several days of your authorization to proceed. However, more important would be when treated effluent is not being pumped to the RIBS as we would like to have a relatively dry bottom condition to work in to perform our soil borings. If you could determine when effluent is not being pumped to the RIBS so as to allow access to the bottom by our ATV equipment, then we can schedule our field work accordingly.
