Plans Submitted By: Mr. Michael Rocchetti, University of Connecticut

Subject: Construction drawings and specs for Gampel Cooling Towers – Project 901795

Executive Summary: This project involves the removal of two 400 ton cooling towers at the Gampel building. The towers will be

replaced with modern units to be located atop a new heated mechanical room in the same area.

This submittal is not in accordance with FM Global Standards. Completion of review comment No. 2 is

required for design acceptance of this submittal. Additionally, several other review comments in this letter are

requesting additional information to be provided when it becomes available. This information will be needed for

full design review of this project.

Scope of Review: This confirms the receipt and review of:

Drawing package dated June 5, 2014

The table of contents for the project manual associated with this project

Draft Construction Cost Estimate Document

The existing 400 ton cooling towers will be removed. The existing exterior mechanical walled compound will be

enclosed to create a heated mechanical room space that will house the following components: A large remote

sump tank for the cooling tower water, new condenser water pumps, piping, valves and controls. The mechanical

room will also be built with two new 4 in. floor drains and a sump pump. The new 400 ton towers will be located

on the roof of this mechanical room. New piping connections and valves will be provided for the condenser water

supply and return lines from the two existing 400 ton chillers in the adjacent mechanical room. The new towers

will be equipped with make up water line and water level controls and the new towers will be integrated into the

existing building management system.

The replacement towers will be modern 400 ton induced draft cross flow cooling towers.

Review Comments: Cooling Towers:

1. Drawing M-501 of this submittal package calls for two FM Approved cooling towers Baltimore Aircoil

Model 3455C_LM/QV. This is considered acceptable per the FM Global approval guide only when

installed in multi-cell (two or more cells) fashion. The exact number of cells chosen is determined by the

application and its anticipated seasonal operating strategy which includes consideration of cell outage due

to fire damage, mechanical failure and preventive maintenance such that sufficient cooling capacity is

available to enable normal business and manufacturing operations to continue throughout the year. Please

provide documentation confirming that these cooling towers will be installed with a cell arrangement

that is in accordance with their FM Approval listing.

This drawing also indicates that the mechanical contractor may propose a substitute model and if this is

done, the replacement tower must be an FM Approved model. Please notify FM Global if a substitute

tower is selected and provide manufacturers cut sheets so that approval listing can be confirmed.

Roof:

2. This project involves the installation of an EPDM roof over the new mechanical room that will be

constructed in the location of the existing cooling towers. Full details of this roof cover were not included

in this submittal; however, loading and uplift design criteria were specified on the drawings. The specified

criteria are not acceptable. The following should be used instead: Snow load - 35 psf, Wind Speed – 100

mph, Importance Factor - 1.15, Exposure Classification – C. Please provide a detailed roof submittal

utilizing these design criteria. The roof submittal should include an FM Global RoofNav number

that specifies all roofing components as an assembly. Additionally, FM Global should be forwarded

the completed FM Global Form 2688, Checklist for Roofing System (attached)

3. Steel deck fastening should be specified in any new roof submittals. Fastening rates should be selected in

accordance with FM Global Property Loss Prevention Data sheet 1-29 Roof Deck Securement and Above

Deck Roof Components.

4. Perimeter flashing and nailer assemblies are specified to be designed and installed per Data Sheet, 1-49,

Perimeter Flashing. Please submit materials and shop drawings that demonstrate compliance with the

specifications.

5. The design of the roof drainage system should be in accordance with Data Sheet 1-54, Roof Loads for New

Construction and capable of handling the 60 min. rainfall event within the primary and secondary

drainage.

Construction:

6. Any new acoustic ceiling tiles, sound attenuation blankets, HVAC duct insulation or building insulation

should be made of FM Approved Class 1 materials or noncombustible materials. It is also acceptable to

use non-plastic material which have been tested to ASTM E-84 and have shown a flame spread rating of

25 or less. Please provide specifications confirming this.

7. The wall material to be used for the new mechanical room could not be located in this submittal. Please

provide additional details. If composite wall panels are to be used please provide documentation

confirming that FM Approved wall panels are to be used.

Sprinkler Protection:

8. The sprinkler system for the new mechanical room should be designed to achieve a density of 0.2 gpm/sq.

ft. over an operating area of 2,500 sq. ft. with a hose stream allowance of 250 gpm. Please provide

hydraulic calculations confirming this. All hydraulic calculations should be based on a water supply test

that is no more than 12 mo. old to ensure an adequate water supply is still available for the proposed

designs.

9. All new fire protection equipment being utilized in this project should be FM Approved. Please provide

FM Global with copies of manufacturer’s technical data sheets for all components being utilized for this

project when they become available.

10. The drawings provided call for listed fire proofing material to be used at all penetrations. Please submit

manufacturers cut sheets for the material to be used so that the listing can be verified.

11. Any new fire alarm system should utilized all FM Approved equipment and be designed, installed and

tested in accordance with Data Sheet 5-40, Fire Alarm Systems. Please submit manufactures cut sheets for

all fire alarm equipment being utilized for review and comment when it becomes available.

Recommendations to Reduce Hazards during Installation: 12. Prohibit smoking in areas where combustibles are stored, where ignitable liquids are stored or dispensed,

near piles of debris, and on the roof. Post “No Smoking” signs. Permit smoking only in designated areas

equipped with proper receptacles.

13. Keep automatic sprinkler in service as long as possible or as long as conditions necessitating sprinklers

exist. In cold weather, where wet pipe sprinkler systems are provided, maintain heat in sprinklered areas.

Take sprinkler piping out of service section by section, to the extent practical and cap as demolition

progress. Check the sprinkler control valve at the end of each work ay to ensure it is open.

14. Any required shutdown of the fire protection control valves should utilized the FM Global Red Tag

Permit system.

15. The FM Global Hot Work Permit system should be used to supervise all hot work operations (such as

cutting, welding, brazing, grinding, soldering, etc.,) performed outside of any designated welding areas. A

written policy statement should specify who has the authority to issue permits on all shifts. In addition, the

constant fire watch should be continued for 1 hr. and the area should be periodically monitored for an

additional 3 hr. after work is completed.

16. Limit the amount of combustibles in the construction area and dispose of combustible rubbish safely and

promptly.

Please respond to the above recommendations to our office within 14 days of receipt of this letter. If there are any
