pending, of which the Contractor has been notified.
MATERIALS AND WORKMANSHIP
The intent of these contract documents is that only materials and workmanship of the best quality and grade will
be furnished. The fact that the specifications may fail to be sufficiently complete in some detail will not relieve

relieve the Contractor of full responsibility of complying with this provision. The specifications for materials and
methods set forth in the contract documents provide minimum standards of quality, which the Owner believes
necessary to procure a satisfactory project.

defective materials and workmanship. Prior to final acceptance, the Contractor shall furnish to the Owner,
a written general guarantee which shall provide that the Contractor shall remedy any defects in the work,
and pay for any and all damages of any nature whatsoever resulting in such defects, when such defects
appear within ONE year from date of final acceptance of the work as a result of defective materials or
workmanship, at no cost to the Owner (City of Lubbock).
17.2 Notwithstanding any provisions contained in the contractual agreement, the Contractor represents and
warrants fault -free performance and fault -free result in the processing date and date -related data
(including, but not limited to calculating, comparing and sequencing) of all hardware, software and
firmware products delivered and services provided under this Contract, individually or in combination, as
the case may be from the effective date of this Contract. Also, the Contractor warrants calculations will
be recognized and accommodated and will not, in any way, result in hardware, software or firmware
failure. The City of Lubbock, at its sole option, may require the Contractor, at any time, to demonstrate
the procedures it intends to follow in order to comply with all the obligations contained herein. _.
17.3 The obligations contained herein apply to products and services provided by the Contractor, its sub-
contractor or any third party involved in the creation or development of the products and services to be
delivered to the City of Lubbock under this Contract. Failure to comply with any of the obligations
contained herein, may result in the City of Lubbock availing itself of any of its rights under the law and
under this Contract including, but not limited to, its right pertaining to termination or default.
17.4 The warranties contained herein are separate and discrete from any other warranties specified in this
Contract, and are not subject to any disclaimer of warranty, implied or expressed, or limitation to the
Contractor's liability which may be specified in this Contract, its appendices, its schedules, its annexes or

materials to be incorporated into the work without paying the tax at the time of purchase.
PROTECTION OF SUBSURFACE LINES AND STRUCTURES

way as to exercise due care to locate and prevent damage to all underground pipelines, utility lines, conduits or
other underground structures which might or could be damaged by Contractor during the construction of the
project contemplated by these contract documents. The City of Lubbock agrees that it will furnish Contractor the
location of all such underground lines and utilities of which it has knowledge. However, such fact shall not
relieve the Contractor of his responsibilities aforementioned. All such underground lines or structures cut or

signs, and lights shall not cease until the date of issuance to Contractor of City's certificate of acceptance of the
project.

use utmost care so as not to endanger life or property and the Contractor shall further use only such

construction activity.
23.2 Explosive materials shall not be stored or kept at the construction site by the Contractor.

contract, it shall be the duty of the Contractor to notify each utility company having structures (above or
below the ground) in proximity to the site of the work of Contractor's intention to use explosives, and
such notice shall be given sufficiently in advance to enable the companies to take such steps as they may
10
q
deem necessary to protect their property from injury. Such notice, however, shall not relieve the '
Contractor of responsibility for any damage resulting from his blasting operations.

Unlisted classifications needed for work not included within
the scope of the classifications listed may be added after
award only as provided in the labor standards contract clauses
(29CFR 5.5 (a) (1) (ii) ) .
In the listing above, the "SU" designation means that rates
listed under the identifier do not reflect collectively
bargained wage and fringe benefit rates. Other designations
indicate unions whose rates have been determined to be
prevailing.
WAGE DETERMINATION APPEALS PROCESS
1.) Has there been an initial decision in the matter? This can
be:
* an existing published wage determination
* a survey underlying a wage determination
* a Wage and Hour Division letter setting forth a position on
a wage determination matter
* a conformance (additional classification and rate) ruling
On survey related matters, initial contact, including requests
for summaries of surveys, should be with the Wage and Hour
Regional Office for the area in which the survey was conducted
because those Regional Offices have responsibility for the
Davis -Bacon survey program. If the response from this initial
contact is not satisfactory, then the process described in 2.)
and 3.) should be followed.
With regard to any other matter not yet ripe for the formal
process described here, initial contact should be with the
Branch of Construction Wage Determinations. Write to:
Branch of Construction Wage Determinations
Wage and Hour Division
U.S. Department of Labor
200 Constitution Avenue, N.W.
Washington, DC 20210
2.1 If the answer to the question in 1.1 is yes, then an
interested party (those affected by the action) can request
review and reconsideration from the Wage and Hour Administrator
(See 29 CFR Part 1.8 and 29 CFR Part 7). Write to:
Wage and Hour Administrator
U.S. Department of Labor
200 Constitution Avenue, N.W.
Washington, DC 20210
The request should be accompanied by a full statement of the
interested party's position and by any information (wage
payment data, project description, area practice material,
etc.) that the requestor considers relevant to the issue.
3.) If the decision of the Administrator is not favorable, an
interested party may appeal directly to the Administrative
Review Board (formerly the Wage Appeals Board). Write to:
Administrative Review Board
U.S. Department of Labor
200 Constitution Avenue, N.W.
Washington, DC 20210
4.) All decisions by the Administrative Review Board are final.
