MEMORANDUM
T , R • A
To: Lyle Oman; Building Official, City of Orono
From: Victor Pechaty,Ted Rozeboom Architects
Date: 12 January 1997 JAN 1 5 1997
Subject: Orono Ice Arena: Response to Remaining Code Issues
This memorandum addresses the code issues listed in Mr. Oman's memo dated January 9, 1997.
I.Plan of Handrails at Bleacher Aisles:
see attached
II. Code Compliance of Roof Assembly:
1.The roofing assembly specified meets the following testing criteria:
UL Class A or B and UBC Section 17-4 as fire retardant
2. UL Standard 1256 for internal burn rating
3. Factory Mutual FM-I-60 wind uplift requirements.
III.Exiting Strategy for Off-Season Uses
The building as designed provides the required exit width to exit the entire occupant load associ-
ated with off-season uses; however, UBC requires 4 exits from spaces with occupant loads over
1000.Two exits must be a minimum of 1/2 of the overall diagonal distance of the ice sheet apart.
The remaining two exits must be arranged a "reasonable distance apart so that if one becomes
blocked the others will be available." (UBC 1003.3)
The total exit width required for the ice sheet area with 1034 occ. x 0.2 =206.8"
The solution is as follows:
1. 10'-0" opening in dasher boards @ zamboni access with exiting through north double
doors.
2. 6'-0" opening in dasher boards @ southeast corner of rink with exiting through "player
entrance".The player entrance doors will be revised from a single door to a 6'-0" double
door.
3. 6'-0" opening in dasher boards @ southwest corner of rink with exiting through 4 doors
into lobby.Architect will design 6'-0" wide portable stair assembly to allow access from
rink level to lobby level.
4. 3'-0" opening in northwest corner of rink with exiting up north bleacher stair to west exit.
The City of Or o is to r- -'ve copies of dasher board drawings for city review to confirm the
location of ex' s in the asher s oard assembly.
Sincerely, Victor Pechaty MA, Project Architect, TRA
