CENTER FOR ALLIED HEALTH AND ATHLETICS FF&E April 24, 2014
SECTION 27 41 00 AUDIOVISUAL SYSTEMS
Marshall Craft Associates, Inc. 27 41 00-35
Project 12032
1. All optical projection systems shall meet the following performance standards:
a. The total averaged light output from a projector, in lumens, shall be within plus-
or-minus 15% of that specified by the projector manufacturer.
b. The light fall-off from the center of the projected image to all four corners, as
measured at the projected image plane, shall not exceed 35% for slide projector
images. The light intensity shall be measured at all five positions of the projected
image after the projector has been adjusted to provide the light output as
specified above.
c. The “corner” locations shall be defined as the four points determined by
intersecting lines drawn 5% of the distance in from the focused edges of the
image.
d. The light meter used for the above measurements shall be properly calibrated
footcandle (or lux) meter and shall be cosine-corrected
e. Projectors, lenses, and mirrors shall be solidly mounted and braced so that there
will be no observable movement in the image induced by motor vibration or other
mechanical operations.
K. Qualification Methods
1. Three methods will be used to qualify the AV system for acceptance.
a. Inspection - A critical observation of qualifying factors, such as quality of
workmanship, equipment placement, routing of cables, adequacy of technical
documentation, etc., that do not lend themselves to demonstration or
measurement.
b. Demonstration - A process of showing by reason or evidence that a given
condition clearly satisfies the requirement.
c. Measurement - A process of determining the actual dimension, capacity, or
amount of something, by measuring using calibrated standards.
2. Acceptance of the Work of this Section shall occur after completion of corrections and
adjustments required by “Punch List” (as generated during Demonstration and
Acceptance Testing of Completed Installation).
3. Owner reserves the right to use equipment, material and services provided as part of
Work of this Section, prior to Acceptance, without incurring any obligation to Accept
any equipment or completed systems until Punch List work is complete and systems
comply with Contract Documents.
3.05 SCHEDULES
A. Shared Lecture Hall
1. The Shared Lecture Hall shall serve as the primary space for multidisciplinary
instructional presentations in the Center for Athletics and Allied Health. This Lecture Hall
shall feature a ceiling mounted video projection system, along with separate program and
speech audio reinforcement systems. The audiovisual system shall also utilize in-room
video cameras and microphones to provide Lecture Capture functionality, which will
enable instructors and students to interact directly with instructors and students in remote
locations, as well as to record and live-stream presentations.
2. The visual display system shall consist of one ceiling mounted video projector capable of
producing images on a motorized screen located at the presentation wall. A ceiling
mounted document camera shall be provided over the presentation area, to enable
instructors to display high-resolution images of a demonstration work area for medical
demonstrations. An in-room video cameras shall also be provided, capable of displaying
images on the in-room displays. This video camera, along with ceiling-hung
microphones, shall be used to record presentations. A dedicated AV recording/streaming
appliance shall be located in an equipment rack in the room, along with a dedicated video
