G40 Site Electrical Utilities
- Lighting Poles
- Exterior lighting poles and fixtures shall match existing in surrounding areas unless
previously approved by the University Architect and the Director of University
Planning.
- Obtain specifications for exterior pedestrian, parking, and roadway lighting from the
Director of University Planning.
- A dispersed placement pattern of pathway lighting is preferred. However, lighting
distribution must ultimately determine the placement. Electrical engineering
consultant shall provide photometric study into contract documents.
- Pedestrian fixtures are to be mounted twelve (12) feet above the ground on dark
bronze aluminum poles.
- Standard pedestrian fixtures are Holophane glass prismatic lens, also known as“acorn” fixtures, with high pressure sodium elements.
- No building mounted flood lights allowed.
- See attached table for university standards on fixtures, poles, and photoelectric cells
for walkway, parking lot, and roadway lighting.
- See attached details on base of poles for walkway and for roadway lighting.
- Electrical Transformers
- Specifications to be provided by Facilities Maintenance & Operations in conjunction
with Auburn University’s infrastructure consultant. The transformer shall be
provided and installed by the contractor as part of the project cost unless previously
approved by the University Architect and Director of Maintenance & Operations.
- Costs for the transformer and associated pad are to be included in the project budget
unless otherwise approved by the University Architect and Director of Maintenance& Operations.
- Underground Ducts
- Ductbanks shall be concrete encased PVC.
- Sufficient spare conduits are to be furnished in underground ductbanks to allow for
installation of one future/additional circuit of the same size/rating as those already
provided with cable/conductor.
- All electrical service is to be provided underground unless previously approved by
the University Architect and the Director of Maintenance and Operations.
Ductbanks shall be provided for the following:
- Primary power distribution
- Secondary power distribution
- Exterior lighting power distribution.
- Telecommunications: Follow the TIA-758 Customer-owned Outside Plant
Telecommunications Infrastructure Standard.
- No overhead telecommunications service allowed. All electrical service is to be
provided underground unless previously approved by the University Architect and
the Director of Maintenance and Operations.
- A most recent copy of the telecommunications standards must be obtained through
the Office of Information Technology.
- Telecommunication design must be included in the building design documents.
- Inter-building backbone pathways are facilities necessary for installation of
telecommunication outside plant trunk/feeder cables between buildings. A minimum
of two 4-inch conduits shall be installed from the appropriate telecommunications
manhole to the building BET telecom room. These conduits shall be concrete
encased and have a pull rope installed in each conduit. Additionally, three 1 ¼ inch
HDPE innerducts shall be installed in one conduit from the manhole to the BET. All
conduits and innerducts shall be certified by the installer by pulling a mandrel from end to end in each conduit with a mandrel provided by the Office of Information
Technology (OIT). The mandrel test shall be preformed in the presence of OIT
personnel. AU Office of Information Technology shall be involved in the early site
plan design stages of new construction projects so that all new telecommunication
duct bank and manholes necessary can be included in the design of the project site
plan. The section length of conduit shall not exceed 183 m (600 ft) between pulling
points.
- For intra-building conduit install a pullbox for every section of conduit that exceeds
90-degrees in bends.
- For ductbanks, no more than 90-degrees of transition between manholes greater
than 200’ apart.
- Make every effort to limit that numbers of bends required. Where bends are
necessary, gradual sweeping bends are to be used. Hard 90-degree bends are not
allowed. No section of conduit shall contain more than two 90-degree bends, or
equivalent between pull points (e.g. handholes, maintenance holes, and vaults). If
there is a reverse (U-shaped) bend in the section, a pull box shall be installed. Backto-
back 90-degree bends must be avoided.
- Telecommunication duct bank designs shall be reviewed and approved by the
Office of Information Technology (OIT).
- Three 1 ¼ inch HDPE innerducts shall be installed by the contractor in one
conduit along the entire run of the telecommunications ductbank as part of the
installation of the ductbank. A mandrel test by the contractor is required to certify
the conduit including innerduct.
- Telecommunications cabling will be installed separately by a qualified
telecommunications contractor approved by the Office of Information Technology
