necessary to determine its Bid for performing and furnishing the Work in accordance with
the time, price and other terms and conditions of the Contract Documents.

Bid is premised upon performing and furnishing the work required by the Contract
Documents and such means, methods, techniques, sequences or procedures of construction
as may be indicated in or required by the Contract Documents, and that the Contract

Subcontractors, Suppliers, and Others.
If the Owner requests the identity of any Subcontractors, Suppliers, or other persons or
organizations to be submitted to the Owner in advance of the specified date prior to the
Effective Date of the Agreement, the apparent Successful Bidder, and any other Bidder
so requested, shall within seven (7) days after the request submit to the Owner a list of
all such Subcontractors, Suppliers and other persons and organizations proposed for those
portions of the Work for which such identification is requested. Such list shall be

or organization if requested by the Owner. If the Owner, after due investigation, has
reasonable objection to any proposed Subcontractor, Supplier, other person or
organization, may, before the Notice of Award is given, request the apparent Successful
Bidder to submit an acceptable substitute in which case the apparent Successful Bidder
shall submit an acceptable substitute. Bidder's Bid price may be increased (or decreased)

such price adjustment in evaluating Bids and making the contract award.
If the apparent Successful Bidder declines to make any such substitution, the Owner may
award the contract to the next lowest Bidder that proposes to use acceptable
Subcontractors, Suppliers, other persons and organizations. The declining to make
requested substitutions will not constitute grounds for sacrificing the Bid security of any
Bidder.

organization against who Contractor has reasonable objection.

increase or decrease in the costs of materials, labor, or other items required for this
project, may be rejected and returned to the Bidder without being considered.

The quantities listed in the Bid Form will be considered as approximate and will be used
for the comparison of bids. Payments will be made to the Contractor only for the actual
quantities of work performed or materials furnished in accordance with the contract. The
quantity of work to be done and the materials may be increased or decreased as provided
for in the Contract Documents.
Submission of Bids.

Bids may be rejected if they show alterations of form, additions not called for, conditional
bids, incomplete bids, erasures or irregularities of any kind. The Owner reserves the
right to waive any irregularities in the bids as received and to reject any and all bids
without qualification(s). More than one bid from an individual, fu'm or parmership,
corporation or association, under the same or different names, will not be considered.

may cause the rejection of all bids in which said Bidder is interested. Bids in which
prices are obviously unbalanced may be rejected.

non-responsive, unbalanced or conditional Bids. Also, the Owner reserves the right to
reject the Bid of any Bidder if the Owner believes that it would not be in the best interest
of the Project to make an award to that Bidder, whether because the Bid is not responsive
or the Bidder is unqualified or has doubtful financial ability or fails to meet any other
pertinent standard or criteria established by the Owner. Discrepancies in the
multiplication of units of Work and unit prices will be resolved in favor of the unit prices.
Discrepancies between the indicated sum of any column of figures and the correct sum
thereof will be resolved in favor of the correct sum.

not the Bids comply with the prescribed requirements, and such alternates, unit prices,
completion time, and other data, as may be requested in the Bid form or prior to the
Notice of Award.

indirect, in any contract with the City, nor shall be financially interested, directly or
indirectly, in the sale to the City of any land, or fights or interest in any land, materials,
supplies or services. This prohibition does not apply when the interest is represented by
ownership of stock in a corporation involved, provided such stock ownership amounts to
less than one percent (1%) of the corporation stock. Any violation of this prohibition will
constitute malfeasance in office. Any officer or employee of the City found guilty thereof
should thereby forfeit his office or position. Any violation of this prohibition with the
knowledge, expressed or implied, of the persons or corporations contracting with the City
shall render the contract voidable by the City Manager or the City Council. The
Contractor represents that no employee or officer of the City has an interest in the
Contractor.
ITEM 1.58 - STATE AND LOCAL SALES AND USE TAXES
SC-1.58
Delete Item 1.58 and substitute the following in lieu thereof:
1.58
Recent legislation has removed the sales tax exemption previously provided by Section
151.311 of the Tax Code covering tangible personal property purchased by a contractor
for use in the performance of a contract for the improvement of City-owned realty.
It is still possible, however, for a contractor to make tax-free purchase of tangible
personal property which will be incorporated into and become part of a City construction
project through the use of a "separated contract" with the City. A "separated contract"
is one which separates charges for materials from charges for labor. Under such a
2-7
Standard Specifications
Supplementary Conditions
contract, the contractor becomes a "seller" of those materials which are incorporated into
the project, such as bricks, lumber, concrete, paint, etc. The contractor issues a resale
certificate in lieu of paying the sales tax at the time such items are purchased. The
contractor then receives an exemption certificate from the city for those materials. (This
procedure may not be used, however, for materials which do not become a part of the
finished product. For example, equipment rentals, form materials, etc. are not considered
as becoming "incorporated" into the project).
Utilization of this "separated contract" approach eliminates the need for bidders to figure
in sales tax for materials which are to be incorporated into the project. The successful
bidder's bid form will be used to develop the "separated contract" and will determine the
extent of the tax exemption. Upon execution of the construction contract, the contractor
shall furnish a breakdown (per item) of 1) materials incorporated into the project; and 2)
labor, equipment, supervision and materials not incorporated into the project.

INSTALLATION OF CABLE
General
The cables shall be installed in the conduit. The conduit must be continuous,
reasonably dry, completely free of debris, and without any sharp projections,
edges, or short bends. The conductors shall be installed in such manner and by
such methods as to insure against harmful stretching of the conductor or damage
to the insulation and shall conform to the recommendations of the cable
manufacturer. The Contractor shall furnish, at the request of the Engineer, at least
two copies of the manufacturer's recommendations, including methods of attaching
pulling tension per conductor size and per radius of conduit bend, and the type of
lubricant to be used.
All cables in a given conduit run shall be pulled at the same time and the
conductors shall be assembled to form one loop in such a manner that the pulling
tension is distributed to all the cables. Long, hard pulls will necessitate the use of
pulling eyes. For short runs, the cables may be gripped directly by the conductors
by forming them into a loop to which the pull wire or rope can be attached. The
insulation on each conductor shall be removed before the loop is formed. The
method used will depend on the anticipated maximum pulling tension in each case.
In many instances, existing conduits which contain signal cable are to be used for
the installation of new cables. In such locations, the existing cable(s) may be used
to pull in the new cables. Should the Contractor desire to install new cables
without removing the existing cables, the new installation shall be done in such a
way as to prevent damage to the existing and/or new cables. In the event of
damage, the Contractor shall bear the responsibility of replacement of defective
cables.
The manufacturer's recommended maximum pulling tensions shall not be exceeded
under any circumstances. If so required by the Engineer, the Contractor shall
insert a dynamometer in the pull wire as the cables are being pulled into the
conduit to demonstrate that the maximum tensions are not being exceeded. The
cable shall be fed freely off the reel into the conduit without making a reverse
curve. At the pulling end, the pull wire and or other suitable devices shall be used
as required to reduce any hazards to the cable during installation. The cables shall
be adequately lubricated to reduce friction and further minimize possible damage.
Such lubricants shall not be the grease or oil type used on lead sheathed cables but
shall be one of several commercially available wire pulling compounds that are
suitable for these kinds of cables. They shall consist of soap, talc, mica, or similar
materials and shall be designed to have no deleterious effect on the cable~ being
used.

The cables shall be neatly trained to their destinations in manholes, cabinets, pole
bases, pullboxes, and all other terminations. The cable manufacturer's
recommended values for the minimum bending radii to which cables may be bent
for permanent training during installation shall be adhered to. These limits do not
apply to conduit bends, sheaves or other curved surfaces around which these cables
may be pulled under tension while being installed. Larger radius bends are
required for such conditions.
Wire and Cable
All wire and cable shall conform to the requirements shown on the plans, except
wire and cable specifically covered by other items of this contract. The minimum
size of conductors shall be as indicated on the plans.
Controller Cabinet Wiring
Wiring for the controller ishall consist of connecting to its terminals (1) wires to
signals (2) wires to detectors (3) wires to pedestrian push buttons (4) the power
wires, (5) the ground wires, and (6) the interconnect wires. At the controller all
conductors from the field: shall be stripped back and an eye hook formed in the
wire. These "hooks" shall be inserted under the binder head screw and tightened
securely. Other wiring for the controller shall be as required by the wiring
diagrams and instructions furnished with the controller by the manufacturer.
All field wiring in cabinets shall be neatly done. Incoming cables shall be trained
to their destination and neatly laced together. Communication and detector lead-in
cables shall be clearly identified by use of metal or plastic tags. For example:
Eastbound Right Lane.
Signal Head Wiring
Wiring for the signal head shall consist of connecting the terminal block in
each signal section to the common terminal block in each signal face and where
applicable, connecting the common terminal block in each signal face to the
terminal block in the signal-head terminal compartment. All such connecting wires
shall be number twelve (12) American Wire Gauge. All conductors running from
any terminal points located in the pole or transformer base to the signal head
terminals shall likewise be number twelve (12) A.W.G. The Contractor shall
furnish the NO. 12 A.W.G. for this work.
Terminals and Splices
Except for controllers, the ends of all wires which are to be attached to terminal
posts shall be provided with solderless terminals that meet the requirements of the

Unless otherwise called for in the plans, splices will be permitted in the wires of
signal conductors only in the base of each signal pole at terminal points called for
in the plans. If lead-in conductors from detectors to controller are of different type
than the detector leads, a water-tight splice, acceptable to the Engineer, may be
made in ground box adjacent to the detector location. Splices at points other than
as stated above may be made only with the written permission of the Engineer. All
splices shall be water tight. Splicing methods shall be in accordance with good
electrical practice and the cable manufacturer's recommendations. All materials
used shall be high quality and specifically intended for these purposes. The cables
shall be trained to their final position and cut to proper lengths. The jacket and

against nicking the conductors. The connector shall be soldered. Heat shall be
applied by the use of hot solder. Heating the connection with a direct flame will
not be permitted. Care shall be used to protect the insulation when soldering~ The
entire surface shall be cleaned taking special care in cleaning outside jacket in
order to remove the wax finish. Before the first layer of tape is wrapped, the
entire area shall be coated with an electric grade rubber cement. After this solvent
has dried, the connection shall be insulated with electrical grade rubber splicing
compound tape to proper thickness. This tape requires a pressure and thus must
be stretched to 2/3 width when applied. The completed splice shall be covered
with a half-lap layer of vinyl plastic electrical tape. This wrapping shall be smooth
but the tape shall not be stretched more than necessary.
Splices in communication cables shall include the shield. Splices between cable
pairs shall be made with Scotchlock soldefless connectors designed for this specific
application. The completed splice shall be insulated with a re-enterable plastic
splice case. Splices at points other than those shown on the plans may be made
only with the written permission of the Engineer.
The Engineer shall select at random at least 5 splices to be thoroughly inspected.
The Contractor shall, in the presence of the Engineer, sectionalize the splice to
expose the various layers of materials and the connector. The splice shall be
thoroughly checked for compliance to these special provisions. The splice shall
then be remade by the Contractor. This work shall not require extra payment, but
is considered subsidiary to other items in the contract. All of the splices selected
for this inspection shall conform to the requirement of these special provisions. If
any splices fail to meet these requirements, ten (10) more splices shall be selected
to random by the Engineer for inspection.
