Dam Committee Report for Dec 11, 2007 LTPOA Meeting

Letter from Dave Taylor, Dec 04, 2007:

Have been busy working on Lake Lorraine.  As of today, we have successfully terminated 350 GPM or 100% of all leakage.  This leakage problem has plagued Lake Lorraine for over 47 years.  Now it's history and the lake should be able to maintain a normal pool elevation in the future.  I am sure our completed work will significantly help property values there.  Also, our work was completed under budget.   
Regards,

Letter of Intent, Dave Taylor, Dec 09, 2007:

RE: Letter of Intent to Perform Leakage Remediation

Dear Trustees,

It is our intent, following Trustees authorization, to perform pressure grouting services designed to significantly reduce leakage presently occurring in the right abutment of Lake Tishomingo Dam.

Our estimated charges to perform this work should be in the range of $100,000 to $120,000 depending on subsurface conditions encountered.

Work would be scheduled to begin approximately April 14, 2008 with estimated completion by May 16, 2008.

We suggest you retain Mr. Don Eskridge, P.E. as Project Engineer.  He will be required to secure construction permits from DNR/Dam Safety and provide engineering support.

We would work directly with Mr. Eskridge to draft applicable remedial procedures to maximize grouting effectiveness and control costs.

Following your acceptance of this letter, by February 15, 2008 we will submit our detailed proposal/contract outlining our specific scope and estimated charges.

Thank you for your consideration.  We look forward to working with you on this project.

Respectfully yours,

GROUTING SERVICE CO.

Rhh comments:

1) Dave Taylor called me to explain the $100,000 to $120,000 estimated cost in the LOI. He said that he really didn't think it would cost $120,000 but since he hasn't done the work he cannot be absolutely certain that it won't cost $120,000.

2) DT also said that the cost of diesel fuel, steel casings, and cement greatly affect his costs and that at this point he does not know how much these materials will cost when he starts work in April 2008. He will give us a better cost estimate in Feb. 2008.

3) A letter of intent ("LOI") is a document outlining an agreement between two parties before the agreement is finalized.
* Signing a letter of intent shows a commitment to each other and to the deal. 
* It also shows a commitment to a time line.
* Once the LOI is signed DT will prepare a formal proposal.
