Re: Gato Building Release of Retainage to D. L. Porter Dear Jim: This letter will confirm our telephone conference of this date concerning the final $80,000 payment due D. L. Porter for work on the Gato Building. This amount is currently being withheld because of issues related to windows, glass and glazing. As I stated, issues related to windows, glass and glazing are warranty issues and retention of these funds is not appropriate. Both D. L. Porter and Preservation Services have demonstrated that they will not walk away from these issues and will continue to cooperate in resolving problems as they occur. If Preservation Services is not paid, they will be forced to take legal action. Based on the above, it is my strongest possible recommendation that these funds be released and final payment in the amount of $80,000 be made to D. L. Porter. I have attached correspondence related to window leaks. My November 9, 2001 letter recommended monitoring window leaks to determine an appropriate course of action. Yesterday, Dent Pierce forwarded a letter to me concerning leaks at various window locations. I spoke to Andy Morrison concerning this issue. He agreed to inspect and seal windows as appropriate and work with me to make recommendations for appropriate repairs. I would like to schedule that work and confirm release of the final payment at the same time. Please call if you have any questions. Your cooperation in this matter is greatly appreciated. -~~ Bert L.

Both Gary and Andy feel that the leaks are occurring at the operable sashes. My independent evaluation supports their opinion. Gary notes in his letter that Monroe County purchased these windows and, therefore, Monroe County is responsible for sealing the sashes or contacting Bliss- Cashier about this problem and/or warranty issues. The decision to direct purchase these windows was made when Lodge terminated their contract in order to maintain the project schedule. This item was part of Change Order No.1, executed concurrently with the D.L. Porter contract. During this negotiation, Preservation Services and D.L. Porter both agreed to give up their mark-up, support costs, profit and overhead related to the windows. Monroe County agreed to provide warehousing of windows, miscellaneous support, and accept responsibility for damage and/or problems with the windows. This issue falls under that category. Andy's letter states that sealant was left with John Kipp along with instructions for sealing the window sashes. I recommend having John do this work. Please call if you have any questions.

I have investigated the problem and have asked our subcontractor to do so as well. I believe strongly that the problem is because the frames are not desigi1ed to be sealed at the vent locations. Attached is a copY of a letter received from Preservation Services, Inc. (PSI), which I ask that you review. In reading the PSI letter it appears they believe as I have previously expressed. that we have no wananty obligations with regard to the windows leaking at the vent locations. I ask that you verify such and advise the County so they can a.ddress. the problem themselves before serious damage is incurred. I mean no disrespect by bowing out of this situation, but if you VIill recall it was the County who decided to purchase these window fratnes direct so as to avoid any chatges on behalf of our cllmpany. Since it docs in fact appear to be a frame problem, then I believe it should be the responsibility of th~ party who purchased th~ fiames, which is in this case the "County!

In February when we last took care of a number of window leaks, the operable sections (vents) were the problem. Apparently, the vents have gaskets which do not seal well enough to keep the water out. At that ) time, we left sealant and instructions with John Kipp; ~e'said he would be happy to deal with any ongoing problems. Since that time John has been told by County personnel not to take such action because of warranty issues. 1 suggest you tell the County that no warranty issue is involved and that John should be permitted to use the sealant to stop the gasket leaks, as necessary.

RE: Gato Courtyard Windows FILE COpy Dear Stephanie, Gary Loer has declined to provide pricing on "permanently sealing" the courtyard windows due to the current glass issues. I concur with his position. My letter to Dent included options for sealing the historic windows. What did you ask Gary to price? Also, it appears that these historic windows did not leak during the recent storm. I had indicated to Dent that the historic courtyard windows would not have as much of a problem with blowing rain as the exterior windows, and the overhang at the roofwill provide some protection. I recommend doing no work at this time, monitor these windows during rain storms, and make a decision based on that knowledge. Please ask Dent to consider this course of action. Bert L.

SEPTEMBER, 1997 ~we~ LuL. Smith . I I I I I I I I I I I I I I I I , EE&G Engineering Study Monroe County Gov't Center Annex, Marathon, FI. 1.0 EXECUTIVE SUMMARY The engineering study performed on the Monroe County Gov't Center Annex has revealed that the HV AC systems that exist in this building cannot provide pQsitive internal pressure as it relates to the atmospheric pressure and cannot consistently provide adequate dehumidification. The existing HVAC systems do not introduce the amount of outdoor air as prescribed by ASHRAE standards. The space around the existing air handling units does not allow for ease of maintenance. The building has a vermin infestation and vermin feces exist above the ceiling spaces that also serve as return air passageways_ The compressor - condensing unit serving the air handling system no. 4 is badly corroded and should be replaced. This report suggests and defines that a new outdoor pretreatment unit be installed on the roof to provide positive pressure, adequate ventilation air, and constant dehumidification for the building. 2.0 PURPOSE OF THIS STUDY AND REPORT The purpose of this study and report is to analyze the existing HV AC systems at the Monroe County Gov't Center Annex, to point out existing problems, and to present recommendations that will remediate these problems. Specific subjects considered were as follows: 1. Determine existing condition and future reliability of all HV AC systems, components, and controls. 2. Determine existing HV AC systems ability to properly dehumidify air within facilities. 3. Determine HV AC compliance with ASHRAE standards for air parameters. 4. Determine appropriate balance of HV AC systems. 5. Determine root cause of negative pressure differentials within the facilities. 6. Determine and make recommendations to modify, repair, or replace HV AC systems and/or components in order to obtain a fully operational HV AC system capable of maintaining appropriate comfort levels within the facility for all building occupants. 3.0 DESCRIPTION OF THE BUILDING The building known as the Monroe County Gov't Center Annex consists of a one story CBS structure located at 490 63rd Street, Marathon, FI. Mile marker 48.5. This building houses Monroe County Gov't offices. This property is located at approximately Latitude 24 degrees _ 5 minutes North and approximate Longitude 81 degrees - 5 min. West. This area can best be described as a hot humid climate with an outdoor ambient cooling design temperature of 93 degrees dry bulb and 78 degrees wet bulb. The annual degree hours that the wet bulb temperature is at or greater than 66 degrees F. is 18,000 ( Air Force manual 88-8 Figure 16) indicating that a significant problem with high moisture content will occur and that HV AC systems must be designed to satisfactorily remove the required amount of moisture from the air to keep the humidity levels in the building under control 1 , r I I I I I I I I I I I I I I I I I , .,".

Dehumidification occuring only when the thennostat calls for cooling. All units are energized on a 24hr/daY365 days per year basis. 5.4 BASIC HUMIDITY CONTROL SYSTEM There is no positive control of the humidity in any of the 4 zones. These air handling systems do not remove any water vapor from the air unless the zone is calling for cooling and the coil is cold . 6.0 FINDINGS 6.1 WET AND DRY BULB TEMPERATURE MEASUREMENTS Measurements of wet and dry bulb temperature readings for the outdoor air and for the SUpply air temperatures leaving each of the four air handlers using wet and dry bulb thermometers. The room thermostats for each of these systems was set for full cooling for the purposes of these tests. The purpose of this testing was to determine the ability of these systems to remove sufficient water vapor from the air and to cool this air enough to keep the zone comfortable. The results of these tests are shown below : UNIT DRYBULB F. WET BULB, F. GRAINS/LB. ---------------------------------------------------------- AHU#1 59 56 64 AHU#2 59 55 58 AHU#3 59 56 62 AHU#4 66 62 77 OUTDOOR AIR 80 78 142 3 These tests indicate that air handling systems 1 thru 3 can reduce the air close to a goal of of 60 grains/lb. Air handler #4 ,however was 17 grains/lb above the goal for keeping the building dry. It should be pointed out that the outdoor intakes were fully blocked off at the time of these tests. If the correct amount of outdoor had been introduced during these tests II I EE&G Engineering Study Monroe County Gov't Center Annex, Marathon, FI. I the results would have shown considerable more moi51"ure content in the SUpply air. I 7.0 ENGINEERING OBSERVATIONS I The following observations were made during the Engineering study: I 1 The existing systems cannot maintain ideal temperatures in all spaces but can maintain the temperature in the lone. I 2 The existing systems cannot maintain desired humidity levels (45-55%) thruout the building because there is no positive control of humidity. 3 The existing systems cannot keep the building under positive pressure I 4 The existing air handlers are not equipped with high efficiency filters and there is no space available to install this type of filters. Installation of high efficiency filters would also impose static pressure requirements above the capabilities of the existing air handlers. I 5 The existing air handlers do not have stainless steel condensate pans and the existing pans are not fully drainable. I 6 The existing air handlers do not have sufficient space around them to facilitate adequate maintenance. I 7 The air handlers are in a room that is a return air plenum. This makes air balance between return air and outdoor air impossible. I 8 The building does not have a positive system of outdoor air introduction. The building does not meet the requirements of ASHRAE 62-89 which requires 20 CFM/person of outdoor air. f 9 Outdoor air intakes have been blocked-off because of their undesirable location near a toilet exhaust fan. 10 Condensing unit no. 4 requires replacement due to salt corrosion. 11 There is high percentage of computer room flooring in this building ; if there is moisture existing in the cavity below the floor it could contribute to the higher humidities that are being experienced. 12 Vermin feces were observed above in the air return plenum above the Ceiling near air handler no. 2 8.0 CONCLUS IONS 1 The HV AC systems in this building are deficient in their abilty to maintain room by room temperatures. but can control zone temperatures. 4 EE&G Engineering Study '-, '~.
