This proposal when executed, shall be incorporated in and shall become an integral part of the "Professional Services Agreement Between Owner and Architect" dated January 20, 2010. I. PROJECT DESCRIPTION The project generally consists of preparation of bid and permit documents as needed to implement the recommendations of the Acoustic Study (the Study) as prepared for Monroe County on April 1, 2011, by Edward Dugger + Associates, P.A. The Study concludes with three recommendations for implementation into the six (6) courtroom spaces generally consisting of Decreasing Problematic Reflections and Echoes; Control of Reverberation Time; and Possible Recording Systems modifications. Services include bid documents through implementation. 11. SCOPE OF SERVICES The Architect and consultant will approach this engagement by the following four (4) tasks. Task 1- Provides for a pre- design on -site meeting to discuss the findings of the acoustical analysis report previously prepared by ED +A, review the proposed improvements, discuss any alternative options that may be available, and confirm and discuss whether the anticipated improvements will be sufficient for the Owner to implement. Should it be determined that the improvements will not be worth the expense, it may be decided that the project concludes at this point. However, if the Owner decides to proceed to the other listed tasks, we will be directed to do so as noted below. In attendance to this meeting will be representatives from ED +A and CSA Architects. Task 2 - Provides for the preparation of bid, permit, and Construction (implementation) for the addition of acoustic panels or fabric to selected walls of the various courtroom and vestibules as indicated in the Study and per manufacturer's recommendations and installation details.

A . Consultants in Architectural Acoustics L� Mechanical / Vibration Noise Control and T Audio / Video / IT Systems PROJECT BACKGROUND Completed in 2007, the Freeman Justice Center is a three story County Courtroom Building built in the Jackson Square area of downtown Key West, Florida. The new Courtroom Building replaced a smaller building situated immediately east of existing building on Jackson Square. Since the opening of the Freeman Justice Center, the various users of the facility have complained of unsatisfactory acoustic conditions within all of the new courtrooms. The firm of Edward Dugger+ Associates, PA was commissioned to review the existing acoustic conditions and make recommendations to improve the environment. a MltiUnat JV*TiCE CUM rill N, • Ita qraii 4,,' 4i qc-* . -. .,. — .vie 1j:yiSrK' Y—�..�C_� EXISTING COURTROOM CONDITIONS As a first step in correcting the difficulties experienced within the various Courtrooms we needed to understand the critiques provided by the various users of the courtrooms including those from the Bench area (Judge, Court Clerk, and Reporter), and those from the Plaintiff/ Defendant Tables and Lectern, and the Gallery (Audience) area. Together with our own observations, acoustic measurements, and acoustic knowledge base regarding these types of spaces we will provide solutions to the acoustic problems and explain how these solutions may be integrated architecturally within the Courtroom environment. 4490 SW Long Bay Drive, Palm City, Florida 34990 t: (772) 286-8351 www.edplusa.com f: (772)221-1960 AA26000667 Freeman Justice Center Courtrooms, Key West, FL 1 April 2011 2 G� EDWARD DUGGER + ASSOCIATES, P.A.

Consultants In Architectural Acoustics r.rr L� Mechanical /Vibration Noise Control and T Audio /Video /IT Systems General We are not sure of the original approach to the acoustic design of the courtrooms but it does seem to be minimal at best. Overall, the courtrooms listening and speaking conditions are best characterized as "difficult'. In working to make modifications to the room, we have carefully examined these complaints and analyzed the space to determine the causes. The changes we propose should dramatically improve the acoustical character of the Courtrooms by substantially decreasing these problems. 4490 SW Long Bay Drive, Palm City, Florida 34990 t: (772) 286 -8351 www.edplusa.com f: (772) 221 -1960 AA26000667 Freeman Justice Center Courtrooms, Key West, FL 1 April 2011 4 G� EDWARD DUGGER + ASSOCIATES, P.A. Consultants in Architectural Acoustics 1 4vA Mechanical /Vibration Noise Control and Audio /Video /IT Systems RECOMMENDED ACOUSTIC IMPROVEMENTS To best explain the changes we recommend, it is easiest to divide them into 3 broad areas of improvements. These architectural areas are then broken down into specific architectural changes that will realize the acoustic desires. I - Decrease Problematic Reflections and Echoes The first major area of acoustic concern is the need to modify the Courtrooms to eliminate or substantially decrease problematic reflections. Many complaints in the Courtrooms can be linked to specific acoustic reflections, especially where parallel walls occur. Because sound travels at approximately 1,100 ft/second, persons in the Courtrooms can often be presented with several distinct time arrivals of sound from multiple sources. The first, and most noticeable arrival, is from the front to back wall. The second is from the side walls. However, there are also numerous reflected paths that sound takes to reach the listener. Reflections off the ceiling, furniture, floor, or even multiple combinations of all three can reach the listener noticeably later than the direct sound. As a result, the listener hears several arrivals; the first is the direct sound, the rest from reflections off of room surfaces. If the time gap between multiple arrivals of sound remains fairly low (less than 30 milliseconds) these multiple arrivals are not a problem. However, strong reflections delayed more than 30 milliseconds from the direct sound source begin to be perceived as echoes. Additionally, image shifts and the masking of speech often result if these late reflections are similar in amplitude to the direct sound. Several architectural features in the room are causing reflected sound to exceed this 30 millisecond time window. To improve speech intelligibility and to control the buildup of sound within the Courtrooms, it is necessary to change these reflections. STI /RASTI is used to measure the perceived affect of echoes and the buildup of sound that masks speech. The STI /RASTI of a Courtroom should fall within the "Excellent" to "Good" range. 4490 SW Long Bay Drive, Palm City, Florida 34990 t: (772) 286 -8351 www.edplusa.com f: (772) 221 -1960 AA26000667 Freeman Justice Center Courtrooms, Key West, FL 1 April 2011 5 EDWARD DUGGER + ASSOCIATES, P.A.

Consultants in Architectural Acoustics r+.r LA Mechanical /Vibration Noise Control and T Audio /Video /IT Systems 1. II — Control of Reverberation Time Our recommendation to transform the acoustics of the Courtrooms involves carefully controlling the amount of sound buildup within the rooms. Our experience has taught us that making sure the reverberation time within the room is appropriate for speech and recording environments is the key to achieving better listening. For a Courtroom acoustical environment the reverberation time should be in the 1.0 to 0.7 second range (averaged mid band between 500 and 1,000 hertz). The attached summaries are for the various Courtrooms, their general dimensions, STI /RASTI ratings, and their existing reverberation times. III — Recording Systems Since recording systems within Courtrooms are important, the following suggestions are made to improve the recording quality. 1. Use boundary microphones whenever possible, especially when the phone system is in conference mode. 2. Consider mounting a boundary microphone in the ceiling between the Judge and Lectern. This position is close to both parties and would provide the strongest signal since the ceiling is a natural acoustic reflector. 3. Where freestanding microphones are used make sure they are directional and not omni- directional microphones. The microphone should just pick up sound right where the user is speaking into it, being careful not to pick up any extraneous sounds. Several microphone manufacturers have variable settings on their microphone heads that can change the pickup pattern and so the correct directionality setting may be used. CONCLUSIONS Our recommendations may be summarized as follows: Courtrooms A This courtroom is the largest of the six with a general room dimension of 60' wide (North to South) and a length of 62' (East to West): 4490 SW Long Bay Drive, Palm City, Florida 34990 t: (772) 286 -8351 www.edplusa.com f: (772) 221 -1960 AA26000667 Freeman Justice Center Courtrooms, Key West, FL 1 April 2011 7 F EDWARD DUGGER + ASSOCIATES, P.A.

Add acoustic treatment (1" thick fabric wrapped fiberglass @ 4 Ibs density) to the East Walls. Cover the whole wall (except for the doors), starting the panels just below the back of the Gallery Seats and continue to the ceiling. 2. Add acoustic treatment (1/2" thick fabric wrapped fiberglass @ 4 Ibs density) to the South Wall. Install on the wall from the wainscot height to the ceiling. Start this treatment in the Northwest comer and continue to the short wall in front of the Gallery area. 3. Add acoustically absorptive treatments (1" thick fabric wrapped TECTUM Finale' panels) to the Entry Vestibules for both the Gallery and Bench doorways.

C. & F These are three medium size courtrooms of the six with a general room dimension of 30' wide (North to South) and a length of 66' (East to West): 1. Add acoustic treatment (1" thick fabric wrapped fiberglass @ 4 Ibs density) to the East Walls. Cover the whole wall (except for the doors), starting the panels just below the back of the Gallery Seats and continue to the ceiling. 2. Add acoustic treatment (1/2" thick fabric wrapped fiberglass @ 4 Ibs density) to the South Wall. Install on the wall from the wainscot height to the ceiling across the whole length of the room. Start this treatment in the Northwest corner and continue to the short wall in front of the Gallery area. 3. Add acoustically absorptive treatments (1" thick fabric wrapped TECTUM Finale' panels) to the Entry Vestibules for both the Gallery and Bench doorways. The panels do not need to cover every square inch of the vestibules. The panels can be applied at the height of the electrical outlets to door height. 4.

Consultants in Architectural Acoustics LA Mechanical /Vibration Noise Control and T Audlo /Video /IT Systems We expect the cost for the acoustical panels to be in the $15 -$25 per square foot range. In addition to the previous mentioned recommendations, a set of drawings should be prepared with every Courtroom illustrated showing the exact location, thickness, type, and installation details. We would like to see and review these drawings before the project is issued for bidding. The type of acoustic panel system can be one of the following types: 1. Fabric cover fiberglass panels which have the fabric glued to the fiberglass surface and then the fiberglass panels are mechanically attached to the wall. If a panel is damaged (unlikely but it can happen) then you must replace the whole panel. 2. Stretch -Wall or Fabric-Trak systems. These systems have a plastic trim piece that is mechanically attached to the wall around the perimeter of where the panels go. The acoustic material (fiberglass or cotton) is then mechanically attached within the center of the perimeter clips. Fabric is placed and pulled into the perimeter attachment strips. This system gives the best flexibility in fabric selection. You can also replace damaged areas by just replacing only the fabric covering that is damaged. If you have any questions about this report, or if there are any issues which we might answer or clarify, please feel free to telephone us. We look forward to working further with you on this exciting and interesting project. 4490 SW Long Bay Drive, Palm City, Florida 34990 t: (772) 286 -8351 www.edplusa.com f: (772) 221 -1960 AA26000667 Freeman Justice Center Courtrooms, Key West, FL 1 April 2011 10 Freeman Justice Center, Key West, Florida 2 9-Mor11 Edward Dugger + Associates, Consultants in Architectural Acoustics ED +A: 10340 Courtroom A SurfmosAru Length Width Hal 100 TOTALS walla 1 kHz t.60 Lao M North 61.75 a - 500 h2 S•a S00 12 Lim 741 East _...... 60 12 720 South 81.75 12 741 Weal Glass/GM 110 12 0.11 0 SubbW 24222 0.11 24222 0.11 2,202 Wood 242.22 Wood 0.28 338:00 1,200 FWAP - added 75 261,00 8.5 100.00 638 Coma 0.11 132,40 FWAP 0.15 85 :53 GWB 61.75 00 382.50 0.80 3,706 Floor S10A0 0.80 $10,00 Collings Carpet 61.75 50 3,705 Sealing Gallery 61.75 29 1,791 -hav 9 18 37MSD 0.05 144 Bench SeMng Areas 1020 0.07 260 24 24 Volume 61.75 60 12 44490 Reverberation Time 230 _ 125 Hz 100 800 Hz 1 kHz t.60 Lao M a -125 h2 Sle 125 a - 250 hz $a 280 a - 500 h2 S•a S00 a - 1000hz 8*0 tk Lim a - 4000hz S'a : 4k D.00 _...... 12914 71014 000 Na 1 sit. 2 kHz 4 kHz Frequency (Hz) laavm�rrrYY - WN- .ubma -6 ow - r- wembe.e�.s.<x,pr Surface Area Calculations (TA= S • a 1 tdla l 1.
