This Section defines processes and procedures for quality assurance applicable to Division 27.
1.02 GENERAL QUALITY ASSURANCE/QUALITY CONTROL (QA/QC)
A.
Design Intent Meeting
1.
The Contractor shall schedule and attend a meeting to review the design with the Engineer
and Owner. The purpose of the meeting will be to ensure that the Contractor fully
understands the design intent as detailed in the Contract Documents. The Contractor shall
thoroughly review the Contract Documents prior to the meeting, and shall document
questions, comments, and/or concerns to be discussed at the meeting. The meeting shall
take place prior to Submittal preparation and submission. Attendees shall include:
i.
Communications Contractor(s)
1)
ii.
iii.

B.
Electrical Contractor
Engineer
Owner
Pre'installation Meeting
1.
Prior to beginning work in a given area (or areas), the Contractor shall schedule and attend
a pre'installation meeting to review and coordinate work within that area with the other
trades. The purpose of the meeting will be to review the communications pathway/raceway
layout and identify and resolve any potential conflicts, to have each trade verify that the
pathway/raceway sizing is sufficient for the cabling to be installed within, to ensure a
consistent installation for all cabling, to minimize interference with adjacent materials and
equipment, and to ensure that communications cabling and equipment is accessible to the
Owner for future modifications and maintenance. The meeting shall take place a minimum
of 30 days prior to communications pathway/raceway rough'in. Attendees shall include:
i.
Communications Contractor(s)
1)
ii.
iii.
iv.
C.

Inspections
1.
The Contractor shall schedule and coordinate all inspections of the work as required by the
Governing Authorities. The Contractor shall be solely responsible for scheduling
inspections by the Governing Authorities at times appropriate to the stage of construction
and the work to be inspected. The Contractor shall provide all assistance as required by
the inspector(s) during their inspection(s).

Should the Governing Authorities require remedial action on the Contractor’s part due
to the failure of the Contractor to schedule inspections at appropriate times, such
work shall be at no additional cost to the Owner.
The Contractor is solely responsible for scheduling inspections such that, should the
work fail inspection, enough time remains in the project schedule to take remedial
action and re'inspect the installation.
Observation of Work
1.
2.
E.
University Center AV Integration

Work will be observed by the Engineer on a periodic basis. Work not found to be in
compliance with the Construction Documents, or not in compliance with the intent of the
Construction Documents, shall be brought into compliance at no additional cost to the
Owner.
The Contractor shall notify the Engineer at least one week in advance of the covering of
concealed work so that the Engineer may schedule on'site observation of the work to be
concealed. Work shall not be concealed until work has been tested (if applicable),
observed by the Governing Authorities (if applicable), and at the Engineer’s discretion,
observed by the Engineer. Should work be concealed prior to such testing and
observation, it shall be uncovered, tested, observed, and restored by the Contractor to the
finished condition at no additional cost to the Owner.
Coordination
1.
2.
The Contractor shall thoroughly examine the Construction Documents, for construction
details and methods that are dependent upon or will affect the work of other trades. The
Contractor is responsible for identifying coordination issues and dependencies, and for
preparing Shop Drawings, work plans and schedules to accommodate or mitigate
coordination issues and dependencies before they arise. Changes necessitated by the
failure of the Contractor to coordinate with the work of other trades shall be at no additional
cost to the Owner.
The Contractor shall confer and cooperate with the other trades, throughout the entire
construction process, in order to coordinate the work in the proper sequence. Typical
coordination issues include but are not limited to:
i.
ii.
iii.
3.
4.
5.
6.
Electrical work, including but not limited to electrical receptacles, power panels,
transformers, the telecommunications grounding system, and the installation of
raceway, device boxes, conduits, cable tray, ladder racking and sleeves.
Ceiling cavity spaces.
Installation of acoustical ceiling tiles and similar finishes that may conceal the work.
Verify that the physical dimensions of each item of equipment fit the available space,
promptly notify the Engineer of any potential conflicts, and await the Engineer’s direction
prior to purchase and rough'in of the equipment.
Coordinate locations of devices with field conditions, unless such locations are specifically
dimensioned or otherwise noted in the Construction Documents. If so noted, verify location
with other affected trades and against existing field conditions, promptly notify the Engineer
of any potential conflicts, and await the Engineer’s direction prior to purchase and rough'in
of the equipment.
Coordinate locations for chases, slots, sleeves, and openings in the building structure. For
new concrete coordinate, locate and provide chases, slots, sleeves, and openings prior to
the pouring of the concrete.
Outages shall be coordinated and scheduled in advance with the Owner at a time and
duration acceptable to the Owner. Outages scheduled at times other than the normal
working hours shall not entitle the Contractor to additional compensation beyond the
original amount bid. Outages without advance notice and prior approval by the Owner are
not acceptable.

Furniture and Casework: Prior to procurement and installation of materials and equipment
within furniture and casework, the Contractor shall coordinate with other trades and verify
all locations, pathway requirements, etc. Materials and equipment installed in furniture and
casework without prior coordination are solely at the Contractor’s risk, and as such, are
subject to possible rejection by the Engineer. Rejected materials and equipment shall be
replaced and modified furniture and casework shall be restored to its original condition at
no additional cost to the Owner.
Verification and Validation
1.
Measurements
i.
2.
The Contractor shall physically verify and validate all measurements on site (i.e.
actual measurements vs. those of the Drawings). Where discrepancies exist which
could affect the Work or the Intent of the Construction Documents, the Contractor
shall notify the Engineer and await the Engineer's direction, prior to procurement and
installation of materials.
Raceway/Pathway Sizes
i.
Prior to procurement and installation of raceway/pathway, the Contractor is
responsible for verifying and validating raceway/pathway (conduit, sleeves, cable
tray, surface raceway, etc.) sizes with any and all trades which will make use of them.
1)
2)
3.
Equipment locations
i.
Prior to the installation of equipment, the Contractor shall coordinate with other trades
and subsequently verify all equipment locations that mount on walls or within ceilings.
This work shall include but shall not be limited to:
1)
2)
3)
4.
G.
The Contractor, in conjunction with the various trades, shall determine the
quantity, types, and outside diameters of the cables to be installed within each
raceway/pathway, and shall verify the cable fill ratios for each pathway based
upon this information. The cable fill ratios shall include spare capacity as
required elsewhere within these Specifications or on the Drawings.
Where the calculated cable fill ratios exceed that recommended by the NEC
and TIA/EIA 569, where the ratios indicate that the raceway/pathway is of
insufficient size, and/or where discrepancies exist between the
raceway/pathway sizes shown on the Drawings and the Contractor’s calculated
sizes, the Contractor shall notify the Engineer and await the Engineer's
direction prior to procurement and installation of the raceway/pathway or cable.
Structural elements such as lighting devices, HVAC equipment, fire protection
devices, and cable tray.
Structural support elements for ceiling mounted devices such as but not limited
to speakers, cameras, projectors and projection screens.
Backing Board for wall mounted devices such as but not limited to equipment
panels, equipment panels, power supplies, head'end equipment, flat panel
displays, speakers, and equipment room devices.
No additional compensation will be approved for additional work or materials required due
to the Contractor’s failure to verify and validate the above.
