RFP # 6518
Technical Specifications
Underground Electric Service Installation
EXHIBIT 3 - REVISED
1. PURPOSE
The purpose of this specification is to provide the information necessary to allow contractors to submit a
proposal on a contract for the installation of certain underground electric utilities for Denton Municipal
Electric (DME). The work will be performed on 13.2/7.62kV Grounded WYE primary overhead and
underground electric utility circuits and related secondary voltages supplied by Denton Municipal
Electric (DME) in Denton, Texas. Projects anticipated for underground construction are residential
subdivisions, commercial developments, electrical substations, and placement of underground lines
along city streets and state roads. This contract will be for the labor, equipment, tools, supervision,
bonds and insurance to complete installation of electric facilities. The contractor is expected to
complete all work in a timely manner, with a minimum of DME supervision. DME will provide all
materials required for construction but will not provide supplies and materials necessary for operating
the contractor’s equipment.
Approximately $2 million was spent under the current contract during the previous three years. While
growth trends appear to be continuing, DME guarantees no minimum amount of construction under any
future contract.
The contract being sought by this invitation will not be an exclusive underground construction contract.
Denton Municipal Electric reserves the right to enter into additional contracts with other contractors for
underground utility construction when, according to its own evaluation, there is need. The following are
examples of situations that might be considered reason for seeking additional contracts:
Workload
Timeframe issues
Specific or special projects
Transmission line construction
Substation construction
Fiber Optic construction
Others
The City may negotiate pricing for any non-contract items after contract has been awarded.

The Contractor shall furnish and erect such barricades, fences, flashers, signals, and signs, and other
precautionary measures for the protection of persons and property as necessary to comply with all
federal, state, and local regulations. The Contractor is responsible for compliance with these regulations
without intervention from DME. Prior to commencement of work, Contractor’s Supervisor and Crew
Foreman/Contractor Coordinator shall determine whether the barricade needs are excessive. If both
agree they are then a price will be negotiated for this. No work will be allowed to begin prior to proper
placement of all barricades, signs, and/or traffic controls. The DME Crew Foreman/Contractor
Coordinator may order that work be stopped immediately if the barricading or traffic control is not
properly set up. Failure of the Contractor to insure proper barricading, signage, and/or traffic control on
a recurring basis may be considered a breach of contract.
This contractor shall provide a phone number, beeper number, or mobile phone number (or numbers)
where a knowledgeable individual can be contacted, on a 24 hour basis, to repair barricades and/or signs
that might be discovered to be inadequate, damaged, vandalized, and/or missing.

party within 2 business days.
In all occurrences of feeder trips or lockouts, the Crew Foreman/Contractor Coordinator, or his
designated representative will visit the work site, review work activities and interview the
Contractor and the workers involved in the incident. A memo shall be prepared by the
Contractor and addressed to the DME Crew Foreman/Contractor Coordinator and Dispatch
Superintendent describing the work process leading up to the feeder interruption, the Contractor
activities during the feeder lockout, and the activities of the crew to get the feeder back on-line.
The DME Crew Foreman/Contractor Coordinator and Dispatch Superintendent memo shall state
what caused the interruption and if the Contractor is at fault or has liability in the incident.
In the event a feeder trip or lockout was caused by or attributable to the acts or omission of the
Contractor, a letter from the Contractor’s management personnel (not field supervisor) shall be
submitted to the City of Denton within two (2) business days explaining the circumstances of the
feeder interruption, and the action and precautions to be taken in the future.
In each instance of a feeder lockout or trip, the Contractor shall cooperate with the City during
the City’s investigation of the lockout, which shall include making Contractor’s employees
involved in the interruption available for interviews.
Once the DME Crew Foreman/Contractor Coordinator and Dispatch Superintendent has
determined that the feeder lockout was caused by or attributable to the acts or omission of the
Contractor, the City may (in each case) elect to terminate the Contract and pursue its legal
remedies or require the Contractor to pay liquidated damages in the amount equal to the
RFP # 6518 – Exhibit 3 Page 7 of 22
summation of the following formula: [ Load of Feeder at the time of Lockout in KW] X [Active
Residential Rate /kWH] X [Time Duration of Outage in hours] + DME Labor + Replacement
Materials Cost + Equipment Rate for each occurrence. The City may, at its election deduct any
liquidated damages from the amount of any approved invoices submitted by the Contractor.
In addition, Owner shall immediately suspend work in progress so that all parties to the Contract can
meet to discuss the details of the project, such as what went wrong and what must be done to correct
safety procedures in order for the Contract to be resumed.

All equipment used on projects shall be clearly marked with the Contractor’s name and LOGO. Any
approved subcontractor’s equipment shall also be similarly marked.
23. FIELD CONDITIONS
DME makes no guarantees as to actual field conditions that may be encountered for any project. The
Contractor, in accordance with state law, is responsible for locating all underground facilities prior to
excavation. DME will provide as much information as is available for each project but makes no
guarantee of accuracy or completeness. In the event the Contractor fails to exercise appropriate caution
or to complete underground locating, all costs for repair shall be the Contractor’s responsibility. Any
restoration shall be with the same type of material and construction as the original, or better.
The Contractor shall be responsible for damage to any underground utilities and associated property
damage as a result of operator error or failure to exercise appropriate caution. Contractors are required to

material from trenching contains rock, sand backfill will be used to one foot above the conduit. Normal
procedure for backfilling duct banks is to backfill with 1 ½ sac concrete at least one foot above the
conduits and complete the backfill with excavated material from the trenching. Use of higher grade sac
concrete will not be allowed unless specifically agreed to by the DME Crew Foreman/Contractor
Coordinator in advance. When streets are excavated, backfill will be 1 1/2 sack concrete. Concrete for
backfill will be the responsibility of the Contractor, billable at a unit price. Crew Foreman/Contractor
Coordinator may require concrete backfill in other trenches as necessary to maintain protection of
conduits or compaction of trenches. Depth of concrete backfill will be designated by the Crew
Foreman/Contractor Coordinator or on the plans. Prices in the proposal are for the concrete material,
handling and placement of concrete. The Contractor will be responsible for removal and proper disposal
of any excess excavated material.
Scrap materials and/or trash will not be backfilled in any excavations under this contract.

shall be stored at a secure site and protected from damage and/or theft prior to installation. Any
materials damaged, stolen, lost or otherwise rendered unusable shall be replaced by the Contractor with
materials of the same brand and quality at no expense to the City of Denton. Should any additional
materials be needed, the Crew Foreman/Contractor Coordinator, or his designated representative will
make that determination prior to additional materials being authorized for issue from the City. The City
may, at its option, make replacement materials available to the Contractor at the warehouse inventory
price including overheads charged to DME for damaged or stolen materials. All packaging materials
will be the responsibility of the Contractor to dispose of properly. The assurance that material
accounting is properly done is the sole responsibility of the Contractor. Material not used on the
project shall be returned to the warehouse. If material is not in a condition such that the City of Denton
Warehouse will accept its return, the Contractor will be charged for the material. If left over material
exceeds initial job estimates, the Contractor will be charged for excess material not returned to DME in
good working and usable condition. Reasonable waste will be allowed.

1. The starting point for the process shall be when the project request is delivered to the contractor by
DME with indication of a preferred start date. The preferred start date shall not be less than 14 calendar
days from the date the plans are delivered to the contractor. Longer planning periods are permissible.
DME and the contractor will coordinate, to the extent feasible, in the development phases of projects to
better facilitate planning for both parties. Benefits could be realized in long range budget forecasting,
better project timing, planning, and in coordinating and optimizing contractor resources and availability.
2. The contractor shall acknowledge receipt of the project request, indicate acceptance of the planned
start date or propose an alternate start date, and shall propose a time to discuss the project. This project
meeting shall be scheduled not less than 7 calendar days before the preferred start date.
3. At the project meeting, the following actions are expected:
1. The contractor shall provide:
A formal estimate of the cost based on the contract unit rates in force at the time of the notice
based on the units shown on the project plans
A proposed time-frame to be allowed for project completion
A list of classification and quantity of expected personnel that will be assigned to the
project
A list of the type and quantity of expected equipment that will be assigned to the project
Raise any issues of concern
2. DME shall provide:
Revised project plans, if any
A description of the project and constraints and answer questions
Raise any issues of concern
3. Jointly, both parties shall (some items may require additional time after the project meeting for
resolution. Resolution must be achieved before the purchase order can be issued):
Review the project plan
Attempt to arrive at a final cost estimate
Establish a formal project start date
Attempt to resolve concerns on all issues or agree on a process and time for resolving issues
RFP # 6518 – Exhibit 3 Page 22 of 22
4. After a formal start date and pricing are established, DME will enter the requisition for the purchase
order based on the agreed contracted pricing.
