Welcome to the Boston Convention & Exhibition
Center (BCEC). The Massachusetts Convention Center
Authority (MCCA) has put this guide together as an
addendum to the BCEC EVENT PLANNING GUIDE and
to assist incoming audio/visual vendors with the
special challenges the BCEC poses. Experience has
shown that achieving a successful show requires
attention to detail and adherence to the guidelines in
this document. While this document is primarily
focused on the Exhibition Halls, it also includes
information on the Grand Ballroom, the North Lobby,
the Meeting Rooms and other areas.
The BCEC opened in 2004 and features:
516,000 square feet of contiguous exhibition
space, easily divided into 10 different
160,000 square feet of meeting room space
A 40,020 square foot, column-free Grand Ballroom
More than 300,000 square feet of registration and
function space
62-covered loading bays
Five elephant doors with full access to the
exhibition hall floor
9 foot x 21 foot freight elevator adjacent to the
loading dock
Wi-Fi enabled Internet access and cell phone
coverage throughout the building
Electrical, In-house Sound System, Rigging,
Telecommunications, Plumbing, Cleaning, Food &
Beverage Services, and Medical are exclusive services
performed by the BCEC. Licensed electricians provide
all building power sources and perform hard-wiring
installations, when required.
Acoustic Properties and Characteristics
Exhibition Halls
Most General Sessions are held in one of the three
Exhibition Halls referenced (north to south) as: Hall A,
Hall B and Hall C. Air walls are used to divide or
configure the halls to suit the event. Hall B can also be
further divided by an air wall into B1 and/or B2. Glass
skybridges span the exhibit floor for easy point-topoint movement.
Ceiling heights range from 96 feet in Hall A to 80 feet
in Hall C with surfaces comprised of polished concrete,
metal and glass. Some areas in Hall A have perforated
steel acoustic surfacing which provides a modest
amount of acoustic treatment.
Access to audio, video, data, CATV, telephone and
power is available through utility floor boxes located
on 30 foot x 30 foot centers.
The RT60 (RT60 is a measurement of how long it
would take a sound to decay 60dB in a large room) for
the Exhibition Halls is just over 9 seconds making it a
challenging space to provide intelligible sound
The Grand Ballroom
The Grand Ballroom is just over 40,000 square feet
with a vaulted slotted wood ceiling. The room can be
divided into two spaces of equal size with an air wall.
The rear (south) wall is also a wood surface and is
constructed with an irregular pattern to act as a
geometric diffuser/re-director. Rigging points (every
15 feet except down the center and supporting 1500
lbs. per point) are conveniently located in the ceiling.
Load in is via a 9 foot x 21 foot freight elevator just
north of the loading dock.
Meeting Rooms
The BCEC has 80 carpeted meeting rooms. The
majority of rooms have a ceiling height of 16’ 6”. The
meeting rooms on Level 2 West known as “mini-Grand
Ballrooms” (Rooms 210 A, B and C) have a ceiling
height of 19’ 0”. Storage is not permitted in any
meeting room without written permission from the
Event Services Manager.
North Lobby
Occasionally used for musical acts, interactive displays
etc. The North Lobby surfaces are polished terrazzo
and glass. There are rigging points every 15 feet but
very limited access to power.
North Exterior Areas
Occasionally used for public speeches and photo ops.
There are no rigging points and limited power.
The Westin Waterfront Hotel
The Westin Waterfront Hotel can be linked to events
at the BCEC and vice-versa. The Westin is connected to
the BCEC through conduit with RG6, Multimode Fiber,
Single Mode Fiber and CAT5 (for phone). Contact your
Event Services Manager for additional information.

Recommended Practices and Solutions
Optional Blackout/Large Windows, 60 foot Blacks:
Qty. 340 feet
The use of heavy (22 oz.) Encore or velour type drape is
strongly recommended to reduce spurious reverb and
flutter echo and should be considered mandatory
when doing audio in any of the exhibition halls and
for blackout. Heavy drape should be used on the south
wall, clearstory windows, as sound baffles and as a
perimeter on the floor. Aisles should be carpeted to
reduce reflected sound off the polished concrete floor.
16 foot Perimeter Pipe and Drape, 10 feet x 16 feet:
Qty.1600 feet (+/-)
Fabric Tabs behind Speakers: Qty. As Needed
Properly aimed and configured line array speaker
systems are also important. Careful control of the
coverage pattern is essential when designing a system
for this space. The hypercardioid rear dispersion of a
line array can be attenuated with the use of fabric
tabs flown behind the array.
All drapes or soft goods not supplied by the ERSP must
be fireproof with current, Boston Fire Department
(BFD)-issued fire certificates for each event said drapes
or soft goods are utilized within the MCCA Facilities.
General Session — Minimum Equipment
Below is an example of the minimum equipment and
soft goods required to provide audio and room
treatment for a speech only general session in Hall C.
Sessions in Hall A or B will be similar depending on the
room set up. These are guidelines only, based on
approved equipment stored on-site by the MCCA’s
preferred in-house audio/visual provider and Exclusive
Rigging Service Provider (ERSP). [This set-up is
Available as a practical turnkey solution at a package
price.] If you are planning on hosting concert acts in
addition to or in place of a general session then
additional treatment and equipment will be required.
Note: Treating the clearstories and south window or
any of the large windows is primarily for blackout
purposes and has the added benefit of dampening the
room acoustics depending on the stage layout.
All rigging equipment not supplied by the ERSP is
subject to safety inspection and approval by the ERSP
and/or the MCCA. If any equipment is deemed unsafe,
then such equipment will not be rigged until the
safety issue is corrected.

4 Clusters of 7 speakers

and accepted safety practices. It is also understood
that the MCCA retains authority over scheduling and
priority for use of freight elevators unless such MCCA
is delegated in writing to the General Service
Contractor in advance of such use. The MCCA reserves

policies and procedures governing the use of freight
elevators. Contractors shall be held responsible for any
damage to the freight elevators as a result of
negligent operation, including over-loading and
improper procedures.
Emergency Procedures

specific details.
Equipment Layover Requests
The Facilities do not provide or reserve permanent
storage areas for contractors. The MCCA reserves the

AV Move-In and Move-Out Procedures
AV Operations and Procedures
The Licensee’s General Service Contractor (GSC) must
work in harmony with the Licensee’s designated AV
company. GSCs are authorized to unload AV
equipment from the loading dock to an AV designated
central location. From there, the AV company
employees are solely responsible to distribute AV
equipment from said central location, to anywhere
within the MCCA facilities (Hynes/BCEC). At the end of
the event, the AV company will then return AV
equipment to the designated central location and it
will be the responsibility of the GSC to load out all AV
equipment from said location.
