The following questions were submitted for clarification and/or to request additional information. All questions
that were submitted are listed below, along with the response and/or information requested. Effective this date,
this addendum forms part of the contract documents and modifies the original IFB.
Question #1: Do the upper bleachers go back as they are installed currently… telescopic, high rise (11-
5/8”) with end rails on one side?
Answer #1: The upper bleachers need to be manual telescopic and high rise with the same number of rows as
existing. Install end rails on both sides of bleachers at a minimum of 12” from the wall to the edge of the end
rail at the closest point to the wall. Distances shall be the same on both sides.
Question #2: At Gettys Middle the lower home side bleachers stop a few rows short of the floor and have
a guardrail at the bottom. Do you want to stay with the same configuration for the new bleachers or
continue them to the floor as is typical?
Answer #2: Install 10 rows of bleachers down to the floor level with 24” rows and a +/- 14” (custom) rise. At
the bottom row install custom guardrails, painted black. Leave aisles open for egress. See attached drawings.
Question #3: What voltage and phase power is being feed to the bleachers at each location and are there
fused disconnects between the panel and junction boxes?
Answer #3: RCEMS is 120V/ Single Phase and GMS is 120V/ Single Phase. Both have wall plug-ins on 30 amp
breakers. There are currently no fused disconnects between the panel and j-boxes; but they can be installed.
Question #4: Can the existing bleachers be removed as soon as school is out with the possibility that the
new ones may not arrive in time to be installed before school starts back?
Answer #4: Yes, please go ahead and remove all existing bleachers from the gyms as soon as May 31st after 12 PM and
by June 7th. This gives us the best possible chance to have the new ones installed before school starts back and will make
installation that much faster. The gym floors are being refinished at Gettys Middle the week of June 3rd and ideally the
the bleachers on court level need to be removed before the floors are refinished the week of June 3rd. Coordinate with
district and flooring contractor.
Question #5: The specs call for the bleachers at RC Edwards to be installed over an extended Labor Day
weekend if they don’t arrive in time for installation before August 20th; however it will likely take a full
week and up to 10 days to install these bleachers which means the gym will be closed during this time.
Answer #5: We’ll have to coordinate the installation closely with the school’s schedule so the gym is available
as quickly as possible. This will also apply to Gettys Middle as the bleachers may need to be stored on the
court level when they arrive. The gym will have to be closed there at least until the lower level bleachers are
