About this file
This is a Construction Sequence specification document for ITB No. 27-402/DL, issued by a Florida authority for the removal and replacement of telemetry cabinets for an existing SCADA (Supervisory, Control, And Data Acquisition) system across phased projects. The contract requires a licensed Florida General or Electrical Contractor to replace thirty-three (33) telemetry cabinets and provide all associated labor, materials, equipment, and incidentals. The work will be executed as a series of phased projects over an initial three-year contract period with an option to renew for an additional one year at the authority's discretion. Bid security in the form of a surety bond or cashier's check is required in an amount not less than five percent (5%) of the total bid amount. All bid submissions must be made electronically through Bonfire by specified deadlines, with questions and clarifications also submitted through that platform by designated dates.
The specification emphasizes critical coordination and operational requirements during construction. The contractor must coordinate all activities with other on-site contractors and the owner's operations to minimize disruption to solid waste landfilling, leachate management, gas collection, and processing operations, with forty-eight hours' notice required before de-energizing or disconnecting any RTU control panel. Temporary access must be maintained to all control buildings, electrical rooms, and outdoor enclosures, with a minimum twenty-foot-wide two-way access required to the Class I landfill area and compost facility for all vehicles including semi-trailer trucks. The contractor must submit a detailed Telemetry Cutover and Downtime Plan, Loop Status and Pre-Commissioning Checklist, and a construction schedule within ten days of notice to proceed. No telemetry cabinet replacement is considered complete until end-to-end loop checks from field instruments to the SCADA screen are successfully verified and signed off by the owner's SCADA system integrator.

SECTION 01014
CONSTRUCTION SEQUENCE
PART 1 – GENERAL
1.01 SITE CONDITIONS
A. Several areas of construction under this Contract may need to be coordinated with other contractors doing work near the limits of construction and must be coordinated with the ongoing operations of the OWNER to allow construction to be completed within the time allowed by Contract Documents.
B. CONTRACTOR is required to coordinate all activities in the interface or common areas with other contractors and/or the OWNER. CONTRACTOR must submit to the OWNER within ten (10) days after notice to proceed a description and schedule for review and approval by the OWNER as to how the common areas will be utilized, recognizing the required coordination with other contractors and/or the OWNER.
C. Where electrical power shutdowns, SCADA network disconnections, or telemetry interruptions are required, CONTRACTOR shall coordinate outages with the OWNER’s operations and SCADA integration personnel. CONTRACTOR shall not de-energize any existing Telemetry Cabinet or telemetry system without written authorization from the OWNER.
D. During testing, commissioning, and loop-checking, CONTRACTOR shall make available the electrical qualified manpower, test equipment, and MANUFACTURER’s system integration representatives required to make any necessary adjustments, programming tweaks, and signal verifications.
1.02 SUBMITTALS
A. Schedule as specified in 01014 1.01B.
B. Telemetry Cutover and Downtime Plan: Detailed step-by-step procedure for decommissioning each existing Telemetry Cabinet, installing the new Telemetry Cabinet, and restoring power/telemetry. The plan must detail temporary control/monitoring measures to be utilized during the cutover window.
C. Loop Status and Pre-Commissioning Checklist: Sample sheets to be used during signal testing to verify all I/O points map correctly to the SCADA Master Station.

1.03 CONSTRUCTION CONSTRAINTS
A. The following is a list of constraints which CONTRACTOR should consider in developing their overall plan of construction. This list is not intended to release CONTRACTOR from the responsibility to coordinate the work in any manner which will ensure project completion within the time allowed. The following areas are not necessarily listed in their required sequence of construction, nor is it intended to be a complete list of work items.
1. Coordination and Cutover constraints
a. CONTRACTOR shall coordinate the work with other on-site contractors (refer to Section 01100).
b. CONTRACTOR shall coordinate all work with OWNER to avoid or minimize disruption of solid waste landfilling, leachate management, gas collection, and solid waste processing operations. CONTRACTOR shall provide OWNER forty-eight
(48) hours’ notice before de-energizing or disconnecting any RTU control panel.
c. CONTRACTOR shall coordinate with the OWNER (SWA Utilities/SCADA Division) for system shutdown and telemetry isolation. During the period when an RTU is offline, CONTRACTOR shall provide means to safely monitor and operate the associated station (e.g., pump station, valve vault) manually or via temporary hardwired bypass controls, ensuring continuous operational safety.
d. CONTRACTOR is responsible for disconnecting, labeling, and protecting all existing field wiring, conduits, and communication cables to be reused. Any damage to existing instrumentation, field wiring, or equipment to remain shall be repaired, recalibrated, or replaced and restored to original condition at no cost to the OWNER.
e. CONTRACTOR shall coordinate with the OWNER’s SCADA system integrator during the physical cutover to verify that all analog, digital, and communication registers are successfully transmitting data to the SCADA host. No Telemetry Cabinet replacement shall be considered complete until end-to-end loop checks (field-instrument-to-SCADA screen) are successfully verified and signed off.
2. Access
a. Temporary access shall be maintained to all RTU control buildings, electrical rooms, and outdoor enclosures. The CONTRACTOR must coordinate work with existing landfill
Removal & Replacement of Telemetry Cabinets for 01014 -3 Existing SCADA Systems – Phased Projects operations and ensure that access to electrical panels and disconnects is kept clear and compliant with NEC clearance standards.
b. Two-way (20 feet wide minimum) access to the Class I landfill area and to the compost facility must be maintained for all vehicles including semi-trailer trucks throughout the construction period.
