Field
Review
After collecting verified field measurements and specific
physical or topographical data, review the overall campus
design with the client and/or other principal concerned parties,
which may include city, municipal, state and federal authorities,
for approval of proposed work to be performed. It should never
be assumed that even the most detailed plan will be unanimously
approved. It would be prudent to have at least an outline
of a back-up plan, in the event that approval is not obtained.
Following
formal approval by all principal parties, the next step in
the process would be to finalize actual construction drawings
and ensure that each project member receives a copy. This
would include everyone from the project administrative staff
to technicians, subcontractors and client personnel involved
with the implementation effort. A complete set of drawings
should be maintained in the project office and be used as
a master plan. Accumulated information collected during field
reviews or actual operations should be transferred to this
plan immediately and communicated to all project personnel.
If this
sounds like overkill, it isn't. Copies of plans are relatively
inexpensive, while mistakes made because of lack of concise
information are quite costly. Revisions, corrections, modifications
and additions or deletions to the design must be communicated
to all planholders as quickly as possible. Accurately detailed
and uniformly used records are essential to the success of
any project.

Plan Content
Proposed plans should include, but not be limited to, all
arterial conduit, ducts, manholes, hand holes, pull boxes,
pedestals, poles and splice points. Specify type, size and
exact locations of all infrastructure components, supports,
enclosures, protectors, type and size of copper or optical
fiber cables, composition, and continuity from point of origination
to destination. Note any special conditions such as poured
or precast concrete, including type and placement of racking,
manhole apparatus, pulling eyes and sumps.
CONDUIT.
Specify and describe the type and size of conduit (minimum
of four inches), schedule 40 PVC, concrete encasement (type),
aluminum or steel. Specify backfill, restoration and overlay
as required.
DISTRIBUTION
AND/OR ENTRANCE. Conduit/cable routes/placement based
on facility usage. Include spares for future use (minimum
one 4-inch conduit).
INNER
DUCT. Provision for fiber optic cable where applicable
and note on plans.
BURIED
CABLES. Not recommended, however if direct buried must
be used, specify width and depth of trench, dirt, backfill,
restoration and overlay. Recommend conduit placement for future
usage (minimum one 4-inch conduit) wherever appropriate. Joint
trench options with other utilities may be considered if applicable
and conforming to NEC articles.
AERIAL.
Recommend specific type/size of aerial cable and support strand,
size, strength, placement techniques, pole and building attachment
hardware, acceptable guying, span lengths, type (schedule)
of poles, length (height), placement depth, etc. Specifications
will depend on cable weight, prevailing weather, soil conditions,
span lengths and loading, clearances, guying requirements
and electrical separations as required by NEC codes, etc.
