About this file
This is a technical specification section for raceways and boxes for electrical systems as part of a solicitation (ITB No. 27-402/DL) issued by a Florida authority for the removal and replacement of telemetry cabinets for an existing Supervisory, Control, And Data Acquisition (SCADA) system. The project involves the replacement of thirty-three (33) telemetry cabinets across a series of phased projects and requires a licensed Florida General or Electrical Contractor to furnish and install complete raceway systems, including all labor, materials, equipment, and incidentals. The contract will have an initial three-year term with an option to renew for an additional one year at the authority's sole discretion. Bid responses must be submitted electronically through Bonfire by the specified deadline, and bidders must confirm their submissions to ensure receipt by the authority.
Bidders are required to submit a Bid Security in the form of a surety company Bid Bond or Cashier's check in an amount not less than five percent (5%) of the total bid amount. The technical specifications detail specific product requirements for rigid conduit, liquidtight flexible metal conduit, flexible couplings, boxes, and fittings from approved manufacturers such as Perma-Cote Company, Carlon, Anaconda Metal Hose Division, Crouse-Hinds Company, and others, or approved equals. Installation requirements include specifications for conduit sizing, spacing, burial depth for underground work, bonding, support intervals, and finishing treatments such as bitumastic coating and epoxy-based silver paint for exposed outdoor components. No Small Business Enterprise (SBE) participation requirement is indicated for this solicitation.

RACEWAYS AND BOXES FOR ELECTRICAL SYSTEMS
PART 1 - GENERAL
1.01 SCOPE OF WORK
A. Furnish and install complete raceway systems as shown on the Drawings and as specified herein.
1.02 APPLICATIONS
A. Except where otherwise shown on the Drawings, or hereinafter specified, all exposed raceways shall be Rigid Galvanized Steel (RGS).
B. PVC-coated RGS conduit shall be used as raceways for shielded wiring.
C. Schedule 40 PVC shall be used underground, unless otherwise noted. Transitions to exposed, outdoor locations shall be made using RGS conduit, starting with the last 90-degree elbow.
D. All conduits of a given type shall be the product of one manufacturer.
E. Combination expansion-deflection fittings shall be used where exposed or embedded conduits cross structure expansion joints.
F. Liquid-tight flexible metal conduit (between 18" and 36" in length) shall be used for all motor terminations and other equipment where vibration is present. All flexible conduits shall use a bonding wire unless a ground wire is included.
G. Unless otherwise hereinafter specified or shown on the
Drawings, all boxes shall be metal. This does not apply to buried work.

C. Conduit hubs shall be manufactured by Meyers Electric Products, Inc., Raco Division, Appleton Electric Company, or an approved equal.
PART 3 - EXECUTION
3.01 INSTALLATION
A. No conduit smaller than ½-inch electrical trade size shall be used, nor shall any have more than four (4) 90-degree bends in any one run. Pull boxes shall be provided as required. Minimum size for floor slabs shall be ¾-inch conduit.
B. An equipment grounding conductor sized per Article 250-95 of the N.E.C. shall be installed on every raceway whether or not shown in the Drawings.
C. All underground conduits shall be buried at least 24 inches below grade.
D. A three (3) inch wide warning tape, red with black stenciled letters "CAUTION - CAUTION - CAUTION ELECTRICAL LINE BURIED BELOW" shall be installed at least 12 inches above and along the entire length of all underground conduits.
E. No wire shall be pulled until the conduit system is complete in all details, or in the case of concealed work, until all rough plastering or masonry has been completed.
F. The ends of all conduits shall be tightly plugged to prevent dust and moisture while under construction.
G. Conduit supports shall be spaced at intervals of eight (8) feet or less, as required to obtain rigid construction.
H. Single conduits shall be supported by means of one-hole pipe clamps in combination with one-screw back plates, to raise conduits from the surface.
