Dean Rowe, FAIA ROWE ARCHITECTS, INC. 100 Madison Street, Suite 200 Tampa, Florida 33602-4704 RE: Clearwater City Hall RAI Project No. 2846.13 AEI Project No. 94137 Dear Mr. Rowe: As you requested, this letter reviews Mechanical and Electrical renovations Three options are presented based renovations required: several options for to this building. on the amount of · Option 1: Maximum Work · Option 2: Intermediate Level of Work · Option 3: Minimum Work OPTION 1: Maximum Work: In February 1993, an existing conditions survey was performed for this building. The analysis of the survey indicated that the Mechanical and Electrical systems were at the end of their useful lives and they should be replaced (see five page summary, attached). A major benefit to their replacement was improved systems efficiency (lower operating costs) as well as improved performance (better room temperature control, lower water consuming plumbing fixtures, and improved lighting) . This option provided for new HVAC systems (two new high efficiency rooftop chillers, two new penthouse air handling units, new low temperature ductwork, new fan powered VAV boxes, new heating boiler, and new temperature controls). Similarly, the plumbing systems recommended new water and drainage piping, new low water use plumbing fixtures, and new gas piping. A complete fire protection (sprinklers and standpipes) was recommended and a new remote fire pump would serve the building systems (to comply with Code). A new JUN-11-96 TUE 14:34 AEI FAX NO. 7891470 P. 03 I I I I I I I I I I I I I I I I I I I Mr. Dean Rowe, AlA Clearwater City Hall June 11, 1996 Page 2 electrical system was recommended (new service entrance wiring capable of present day electrical demands), new high efficiency lighting, and new fire alarm and communications systems. The systems provided would be similar to the modern systems installed in the new Municipal Service Building and new Police Headquarters Building. A recent meeting with Messrs. Bill Baird and Jim Wood confirmed that the Mechanical and Electrical systems are approaching the end of their useful lives. Besides difficulties ln obtaining spare parts, component failure rates are increasing. For example, one of the two chillers is not operating until repairs can be made. If the larger (rather than smaller) chiller had failed, the building would not be able to maintain cooling if a Commission Meeting was held before repairs were completed. Other conditions of the systems include: · Numerous water leaks in chilled water piping are occurring. · The air handling unit has a rusted drain pan. · Duct leaks continue to be patched. · Access to several VAV boxes is not possible unless renovations (walls) that have been added are removed. · The pneumatic controls system is out of calibration and causing operating challenges for maintenance staff. · Plumbing leaks continue (an especially high frequency in 1993) . · The Electrical system continues to be patched (bus bars in the penthouse Motor Control Center have been replaced) . · Replacement circuit breakers are becoming very hard to locate. · The insulation on conductors is hardening and cracking. OPTION 2: Intermediate Work: This option is intended to be a variation between the Maximum Work (Option 1) and Minimum Work (Option 3). While it is theoretically possible to perform some intermediate work level for each of the systems, practically it is not viable, since the cost effectiveness of postponing part of the work results in significantly higher total construction costs. Therefore, for the purposes of this analysis, this level of work is limited to only replacement of the two chillers, replacement of the existing air handling unit, replacement of JUN-11-96 rUE 14:35 I- I I I I I I I I I I I I I I I I I I AEI FAX NO. 7891470 p, 04 Mr. Dean Rowe, AlA Clearwater City Hall June 11, 1996 Page 3 VAV boxes, and accesories (since these are the major two components immediately affecting building operation). Since the equipment is only being replaced in-kind and system redesign is not occurring, the remainder of the building systems do not have to be changed to meet present day Codes (such as larger outside air quantities). Again, while this minimal/intermediate work replaces these components, their usefulness and sizing in a new modern day system will require more chillers (additional capacity). The old sizing does not provide enough cooling for new Code required ventilation. If the equipment is oversized now for the future, the building's electrical system will require upgrading to present day Code, since the old system provides less cooling and uses less electricity. OPTION 3: Minimum Work: This year (1996), minor renovations were planned that were primarily intended to address immediate Code deficiencies (such as the addition of a separate exit from the third floor assembly area). However, work was severely limited to only the most pressing items, due to a previously established budget goal ($500,000). RECOMMENDATIONS: OPTION 1 is recommended to be implemented. OPTION 2 is not recommended, since the replacement chillers, air handling unit, VAV boxes, and accessories will have limited usefulness in the modern mechanical system when it is finally implemented. OPTION 3 is not recommended since it results in wasted effort (some of the work being performed to satisfy immediate Code requirements would not be used if OPTION 1 was selected). If a major equipment item or major system component replacement was necessitated immediately (such as a chiller or air handling unit failure), the replacement unit would not be as useful in a new system as if it were designed as part of an overall retrofit. For example, a low temperature air system would use different equipment of different capacities as the old conventional system components being used now. Additionally, if a system component failure occurs before replacement (such as the old, hardened, insulation on JUN-11-96 TUE 14:35 AEI FAX NO. 7891470 P. 05 I I I I I I I I I I I I I I I I I I I Mr. Dean Rowe, AlA Clearwater City Hall June 11, 1996 Page 4 electrical wiring cracks and fails), the building may experience an extended shutdown or severely restricted operation until repairs were made. For these reasons, a planned, scheduled, and optimized Mechanical and Electrical systems replacement is recommended to be implemented (OPTION 1) . Please contact me if you, have any questions.

OPTION 1: Maximum Work (complete renovation). The Division 15 estimated to be: and Division 16 construction costs are . HVAC Plumbing Fire Protection Electrical TOTAL $ 14.50 / GSF 2.35 / GSF 2.00 / GSF 8.75 / GSF $ 27.60 / GSF x 25,000 SF = $690,000 . . . As previously noted in the original Municipal Services Building design, communications systems (such as telephone, computer, video, and security) are not included in the above construction costs. It is noted that the original Municipal Services Building was priced within budget. Furthermore, the present bidding climate is also favorable. As a result, we believe these construction costs can be achieved. FEE: Our FEE for the OPTION 1 Mechanical and Electrical Work is based on the OMS fee curve for a $1,500,000 total cost (Fee curve "Off for a total building renovation of an office building) : 6.6% x 0.67 x $690,000 = $30,510.
