than materials and equipment specified as furnished by others)and perform aU opera ons
necessary and required to prepare land sites and existing building sites for installation of
Personal Communications Services(PCS)Base Transmission Stations(BTS).
2. The Scope of work includes the installation of PCS antennas on the side of the White ear Lake
Water Tower located on Centerville Road.A Base Transmission Station will be loca d inside
the tower on the south west portion of the floor.Coaxial cable will be run from the
transmission equipment to antennas located in pairs at specific locations on the side o the
tower about 95 feet above the ground.Electrical service will be supplied to the ission
equipment from an existing pad mounted transformer located outside and west of the wer.Tl
lines will also be connected to the equipment.

system to each terminai cabinet or central equipment location.
4. Separately derived systems required by NEC to be grounded shall be grounded as app oved by
the authority having jurisdiction.
5. Installation, General: Ground electrical systems and equipment in accordance w NEC
except where grounding in excess of NEC requirements is iadicated.
6. Electrical Grouad Bus: Size, location, and amangement as indicated. Space 1 inch m wall
and support from wa116 inches above finished floor,except as otherwise indicated..
�• Cn'°und Rods: Locate a minimum of one-rod length from each other and at least e same
distance from any other grounding electrode. Interconnect grouad rods with bare co ductors
buried at least 24 inches below grade. Connect bare-cable ground conductors to gro d rods
by means of exothermic welds except as otherwise indicated. Make these connections 'thout
damaging the copper coating or exposing the steel. Drive rods until tops are 6 inche below
finished floor or final grade except as otherwise indicated.
8. Grounding Electrode Conductor. Provide insulated copper conductor, sized as indic ted, in
conduit Bond the ground conductor conduit to the conductor at each end Where a di lectric
fittiag is installed in the main metallic water service pipe, connect tlie ground conducto to the
street side of the fitting. Do not install a grounding jumper around dielectric fittings. B nd the
ground conductor conduit to the conductor at each end.
9. Braided-Type Bonding Jumpers; Install to connect grouad clamps on water meter pi ing to
electrically bypass water meters. Use elsewhere for flexible bonding and gto ding
connections.
I0. Route grounding and bonding conductors using the shortest and straightest paths ssible
. without obstcucting access or placing conductors where they may be subjected to in,
impact,or damage,except as indicated.

_ 11. UFER Ground; Fabricate with 20 feet of conductor laid lengthwise in exca ation for
foundation or footings. Install so conductor is within 2 inches of the bottom of th concrete.
Where base of foundation is less than 20 feet in lengt6, coil excess conductor base of
foundation. Bond conductor to reinforcing steel at four locations,minimum. Extend nductor
below grade and connect to building grounding grid, grounding electrode con uctor, or
grounding electrode.
12. Connections: Make connections in such a manner as to minimize possibility of galv ic action
or electrolysis. Select connectors, connection hardware, conductors, and connectio methods
so metals in direct contact will be galvanically compatible.
a. Use electroplated or hot-tin-coated materials to assure high conductivity and m e points
of contact closer in order of�lvanic series.
b. Make connections with clean bare metal at points of contact

e. Coat and seal connections involving dissimilaz metals with inert material su as red
lead paint to prevent penetiration of moisture to contact surfaces.
13. Exothermic Welded Connections: Use for connections to stiuctural steel and for und rground
. connections except those at test wells. Install at connections to ground rods d plate
� electrodes. Comply with manufacture�s written recommendations. Welds that are p ffed up
, or that show convex surfaces indicatiag improper cleaaing are not acceptable.
14. Tighten grounding and bonding connectors and terminals, including screws and lts, in
accordance with manufacture�'s published torque dghtening values for connectors bolts.
Where manufacturer's torquing requi��ents are not indicated, tightett connections to comply �
with tightening torque values specified ia LTI,4g6A and UL 486B.
15. Compression-Type Conne�tions: Use hydraulic compression tools to provide the correct
circumferential pressure for compression connectors, LTse tools and dies recommende by the
manufacturer of the connectors, provide embossing die code or other standard method make
a visible indication that a connector has been adequately compressed on the conductor.
16. Moishue Protection: Where insulated conductors are connected to ground rods or ouad
buses, insulate the entire area of the connection and seal against moisture penetration of the
insulation and cable.
17. Tests: Subject the completed grounding system to a megger test at each location ere a
ma�cimum gruund resisrtance level is specified,at service disconnect enclosure ground te inal,
aad at ground test wells. Measure ground resistance without the soil being moistened y any
means other than natural precipitation or natural drainage or seepage and without ch mical
treatrnent or other artificial means of reducing natural ground resistance. Perform tests y the

4. Unfenced substations and pad-mounted equipment: 5 ohms.
5. Manhole grounds: 10 ohms.
b. Deficiencies: Where ground resistances exceed specified values,and if direc modify
the grounding system to reduce resistance values. Where measures are d' d that
exceed those indicated the provisions of the Contract,covering changes will app y.
