not execute such changes pending the receipt of an executed CHANGE ORDER or fur-
ther instruction from the OWNER.

ditions of the CONTRACT DOCUMENTS and the WORK embraced shall be commenced
on a date specified in the NOTICE TO PROCEED.

into consideration the average climatic and economic conditions and other factors pre-
vailing in the locality of the WORK.
15.3 If the CONTRACTOR shall fail to complete the WORK within the CONTRACT
TIME, or extension of time granted by the OWNER, then the CONTRACTOR will pay
to the OWNER the amount for liquidated damages as specified in the BID for each cal-
endar day that the CONTRACTOR shall be in default after the time stipulated in the
CONTRACT DOCUMENTS.

15.4.2 To unforeseeable causes beyond the control and without the fault or negli-
gence of the CONTRACTOR, including but not restricted to, acts of God, or of the pub-
lic enemy, acts of the OWNER, acts of another CONTRACTOR in the performance of a
contract with the OWNER, fires, floods, epidemics, quarantine restrictions, strikes,
freight embargoes, and abnormal and unforeseeable weather: and
Page 12 of 26

by the ENGINEER for failure to comply with the CONTRACT DOCUMENTS, whether
incorporated in the construction or not, and the CONTRACTOR shall promptly replace
and re-execute the WORK in accordance with the CONTRACT DOCUMENTS and with-
out expense to the OWNER and shall bear the expense of making good all WORK of
other CONTRACTORS destroyed or damaged by such removal or replacement.
16.2 All removal and replacement WORK shall be done at the CONTRACTOR'S ex-
pense. If the CONTRACTOR does not take action to remove such rejected WORK with-
in ten (10) days after receipt of WRITTEN NOTICE, the OWNER may remove such
WORK and store the materials at the expense of the CONTRACTOR.
17. SUBSURFACE CONDITIONS
17.1 The CONTRACTOR shall promptly, and before such conditions are disturbed,
except in the event of an emergency, notify the OWNER by WRITTEN NOTICE of:
17.1.1 Subsurface or latent physical conditions at the site differing materially from
those indicated in the CONTRACT DOCUMENTS; or
17.1.2 Unknown physical conditions at the site, of an unusual nature, differing materi-
ally from those ordinarily encountered and generally recognized as inhering in WORK
of the character provided for in the CONTRACT DOCUMENTS.
Pam 11 of 9R
17.2 The OWNER shall promptly investigate the conditions, and if he finds that such
conditions do so materially differ and cause an increase or decrease in the cost of, or
in the time required for, performance of the WORK, an equitable adjustment shall be
made and the CONTRACT DOCUMENTS shall be modified by a CHANGE ORDER.
Any claim of the CONTRACTOR for adjustment hereunder shall not be allowed unless
he has given the required WRITTEN NOTICE; provided that the OWNER may, if he de-
termines the facts so justify, consider and adjust any such claims asserted before the
date of final payment.
18. SUSPENSION OF WORK, TERMINATION AND DELAY
18.1 The OWNER may, at any time and without cause, suspend the WORK or any por-
tion thereof for a period of not more than ninety days or such further time as agreed
upon by the CONTRACTOR, by WRITTEN NOTICE to the CONTRACTOR and the
ENGINEER which notice shall fix the date on which WORK shall be resumed. The
CONTRACTOR will resume that WORK on the date so fixed. The CONTRACTOR will
be allowed an increase in the CONTRACT PRICE or an extension of the CONTRACT
TIME, or both, directly attributable to any suspension.
18.2 If the CONTRACTOR is adjudged a bankrupt or insolvent, or if he makes a gen-
eral assignment for the benefit of his creditors, or if a trustee or receiver is appointed
for the CONTRACTOR or for any of his property, or if he files a petition to take ad-
vantage of any debtor's act, or to reorganize under the bankruptcy or applicable laws,
or if he repeatedly fails to supply sufficient skilled workmen or suitable materials or
equipment, or if he repeatedly fails to make prompt payments to SUBCONTRACTORS
orfor labor, materials or equipment or if he disregards laws, ordinances, rules, regula-
tions or orders of any public body having jurisdiction of the WORK or if he disregards
the authority of the ENGINEER, or if he otherwise violates any provision of the CON-
TRACT DOCUMENTS, then the OWNER may, without prejudice to any other right or
remedy and after giving the CONTRACTOR and his surety a minimum of ten (10) days
Page 14 of 26
from delivery of a WRITTEN NOTICE, terminate the services of the CONTRACTOR and
take possession of the PROJECT and of all materials, equipment, tools, construction
equipment and machinery thereon owned by the CONTRACTOR, and finish the WORK
by whatever method he may deem expedient. In such case the CONTRACTOR shall
not be entitled to receive any further payment until the WORK is finished. If the un-
paid balance of the CONTRACT PRICE exceeds the direct and indirect costs of com-
pleting the PROJECT, including compensation for additional professional services, such
excess shall be paid to the CONTRACTOR. If such costs exceed such unpaid balance,
the CONTRACTOR will pay the difference to the OWNER. Such costs incurred by the
OWNER will be determined by the ENGINEER and incorporated in a CHANGE
ORDER.
18.3 Where the CONTRACTOR'S services have been so terminated by the OWNER,
said termination shall not affect any right of the OWNER against the CONTRACTOR
then existing or which may thereafter accrue. Any retention or payment of monies by
the OWNER due the CONTRACTOR will not release the CONTRACTOR from compli-
ance with the CONTRACT DOCUMENTS.
18.4 After ten (10) days from delivery of a WRITTEN NOTICE to the CONTRACTOR
and the ENGINEER, the OWNER may, without cause and without prejudice to any
other right or remedy, elect to abandon the PROJECT and terminate the Contract.
In such case, the CONTRACTOR shall be paid for all WORK executed and any expense
sustained plus reasonable profit.
18.5 If, through no act or fault of the CONTRACTOR, the WORK is suspended for a
period of more than ninety (90) days by the OWNER or under an order of court or
other public authority, or the ENGINEER fails to act on any request for payment within
thirty (30) days after it is submitted, or the OWNER fails to pay the CONTRACTOR
substantially the sum approved by the ENGINEER or awarded by arbitrators within
thirty (30) days of its approval and presentation, then the CONTRACTOR may, after
ten (10) days from delivery of a WRITTEN NOTICE to the OWNER and the ENGINEER,
terminate the CONTRACT and recover from the OWNER payment for all WORK exe-
Pana IA of 7r.
cuted and all expenses sustained. In addition and in lieu of terminating the CON-
TRACT, if the ENGINEER has failed to act on a request for payment or if the OWNER
has failed to make any payment as aforesaid, the CONTRACTOR may upon ten (10)
days notice to the OWNER and the ENGINEER stop the WORK until he has been paid
all amounts then due, in which event and upon resumption of the WORK, CHANGE
ORDERSshall be issued for adjusting the CONTRACT PRICE or extending the CON-
TRACT TIMEor both to compensate for the costs and delays attributable to the stop-
page of the WORK.
18.6 If the performance of all or any portion of the WORK is suspended, delayed, or
interrupted as a result of a failure of the OWNER or ENGINEER to act within the time
specified in the CONTRACT DOCUMENTS, or if no time is specified, within a reason-
able time, an adjustment in the CONTRACT PRICE or an extension of the CONTRACT
TIME, or both, shall be made by CHANGE ORDER to compensate the CONTRACTOR
for the costs and delays necessarily caused by the failure of the OWNER or ENGINEER.
19. PAYMENTS TO CONTRACTOR
19.1 At least ten days before each progress payment falls due (but not more often than
once a month), the CONTRACTOR will submit to the ENGINEER a partial payment
estimate filled out and signed by the CONTRACTOR covering the WORK performed
during the period covered by the partial payment estimate and supported by such
data as the ENGINEER may reasonably require. If payment is requested on the basis
of materials and equipment not incorporated in the WORK but delivered and suitably
stored at or near the site, the partial payment estimate shall also be accompanied by
such supporting data, satisfactory to the OWNER, as will establish the OWNER's title
to the material and equipment and protect his interest therein, including applicable
insurance. The ENGINEER will, within ten days after receipt of each partial payment
estimate. either indicate in writing his approval of payment and present the partial
payment estimate to the OWNER, or return the partial payment estimate to the CON-
TRACTOR indicating in writing his reasons for refusing to approve payment. In the
latter case, the CONTRACTOR may make the necessary corrections and resubmit the
Page 16 of 26
partial payment estimate. The OWNER will, within ten days of presentation to him of
an approved partial payment estimate, pay the CONTRACTOR a progress payment on
the basis of the approved partial payment estimate. The OWNER shall retain ten (10%)
percent of the amount of each payment until final completion and acceptance of all
work, covered by the CONTRACT DOCUMENTS. The OWNER at any time, however,
after fifty (50%) percent of the WORK has been completed, if he finds that satisfactory
progress is being made, shall reduce retainage to five (5%) percent on the current and
remaining estimates. On completion and acceptance of a part of the WORK on which
the price is stated separately in the CONTRACT DOCUMENTS, payment may be made
in.full, including retained percentages, less authorized deductions.
19.2 The request for payment may also include an allowance for the cost of such ma-
jor materials and equipment which are suitably stored either at or near the site.
19.3 All WORK covered by partial payment made shall thereupon become the sole
property of the OWNER, but this provision shall not be construed as relieving the CON-
TRACTOR of the sole responsibility for the care and protection of the WORK upon
which payments have been made or the restoration of any damaged WORK, or as a
waiver of the right of the OWNER to require the fulfillment of all terms of the CON-
TRACT DOCUMENTS.
19.4 Upon completion and acceptance of the WORK, the ENGINEER shall issue a cer-
tificate attached to the final payment request that the WORK has been accepted by him
under the conditions of the CONTRACT DOCUMENTS. The entire balance found to be
due the CONTRACTOR, including the retained percentages, but except such sums as
may be lawfully retained by the OWNER, shall be paid to the CONTRACTOR within
thirty (30) days of completion and acceptance of the WORK.
19.5 The CONTRACTOR will indemnify and save the OWNER or the OWNER'S agents
harmless from all claims growing out of the lawful demands of SUBCONTRACTORS,
laborers, workmen, mechanics, materialmen, and furnishers of machinery and parts
Pam 17 of 99
thereof, equipment, tools, and all supplies, incurred in the furtherance of the perform-
ance of the WORK. The CONTRACTOR shall, at the OWNER'S request, furnish satis-
factory evidence that all obligations of the nature designated above have been paid,
discharged, or waived. If the CONTRACTOR fails to do so the OWNER may, after hav-
ing notified the CONTRACTOR, either pay unpaid bills or withhold from the CON-
TRACTOR'S unpaid compensation a sum of money deemed reasonably sufficient to
pay any and all such lawful claims until satisfactory evidence is furnished that all lia-
bilities have been fully discharged whereupon payment to the CONTRACTOR shall be
resumed, in accordance with the terms of the CONTRACT DOCUMENTS, but in no
event shall the provisions of this sentence be construed to impose any obligations upon
the OWNER to either the CONTRACTOR, his Surety, or any third party. In paying any
unpaid bills of the CONTRACTOR, any payment so made by the OWNER shall be con-
sidered as a payment made under the CONTRACT DOCUMENTS by the OWNER to
the CONTRACTOR and the OWNER shall not be liable to the CONTRACTOR for any
such payments made in good faith.
19.6 If the OWNER fails to make payment 30 days after approval by the ENGINEER,
in addition to other remedies available to the CONTRACTOR, there shall be added to
each such payment interest at the maximum legal rate commencing on the first day
after said payment is due and continuing until the payment is received by the CON-
TRACTOR.
20. ACCEPTANCE OF FINAL PAYMENT AS RELEASE
20.1 The acceptance by the CONTRACTOR of final payment shall be and shall op-
erate as a release to the OWNER of all claims and all liability to the CONTRACTOR
other than claims in stated amounts as may be specifically excepted by the CONTRAC-
TOR for all things done or furnished in connection with this WORK and for every act
and neglect of the OWNER and others relating to or arising out of this WORK. Any pay-
ment, however, final or otherwise, shall not release the CONTRACTOR or his sureties
from any obligations under the CONTRACT DOCUMENTS or the Performance Bond
and Payment Bonds.
Page 18 of 26
21. INSURANCE
21.1 The CONTRACTOR shall purchase and maintain such insurance as will protect
him from claims set forth below which may arise out of or result from the CONTRAC-
TOR'S execution of the WORK, whether such execution be by himself or by any SUB-
CONTRACTOR or by anyone directly or indirectly employed by any of them, or by
anyone for whose acts any of them may be liable:
21.1.1 Claims under workmen's compensation, disability benefit and other similar em-
ployee benefit acts;
21.1.2 Claims for damages because of bodily injury, occupational sickness or disease,
or death of his employees;
21.1.3 Claims for damages because of bodily injury, sickness or disease, or death of

and
21.1 Claims for damages because of injury to or destruction of tangible property,
including loss of use resulting therefrom.
21.2 Certificates of Insurance acceptable to the OWNER shall be filed with the
OWNER prior to commencement of the WORK. These Certificates shall contain a pro-
vision that coverages afforded under the policies will not be cancelled unless at least
fifteen (15) days prior WRITTEN NOTICE has been given to the OWNER.
21.3 The CONTRACTOR shall procure and maintain, at his own expense, during the
CONTRACT TIME, liability insurance as hereinafter specified;
21.3.1 CONTRACTOR'S General Public Liability and Property Damage Insurance in-
cluding vehicle coverage issued to the CONTRACTOR and protecting him from all
claims for personal injury, including death, and all claims for destruction of or damage
to property, arising out of or in connection with any operations under the CONTRACT
DOCUMENTS, whether such operations be by himself or by any SUBCONTRACTOR
under him, or anyone directly or indirectly employed by the CONTRACTOR or by a
SUBCONTRACTOR under him. Insurance shall be written with a limit of liability of
not less than $200,000 for all damages arising out of bodily injury, including death, at
any time resulting therefrom, sustained by any one person in any one accident; and a
limit of liability of not less than $500,000 for any such damages sustained by two or
more persons in any one accident. Insurance shall be written with a limit of liability
of not less than $100,000 for all property damage sustained by any one person in any

tained by two or more persons in any one accident.
21.3.2 The CONTRACTOR shall acquire and maintain, if applicable, Fire and Extended
Coverage insurance upon the PROJECT to the full insurable value thereof for the bene-
fit of the OWNER, the CONTRACTOR, and SUBCONTRACTORS as their interest may
appear. This provision shall in no way release the CONTRACTOR or CONTRACTOR'S
surety from obligations under the CONTRACT DOCUMENTS to fully complete the
PROJECT.
21.4 The CONTRACTOR shall procure and maintain, at his own expense, during the
CONTRACT TIME, in accordance with the provisions of the laws of the state in which
the work is performed, Workmen's Compensation Insurance, including occupational
disease provisions, for all of his employees at the site of the PROJECT and in case any
work is sublet, the CONTRACTOR shall require such SUBCONTRACTOR similarly to
provide Workmen's Compensation Insurance, including occupational disease provi-
sions for all of the latter's employees unless such employees are covered by the protec-
tion afforded by the CONTRACTOR. In case any class of employees engaged in hazard-
Page 20 of 26
ous work under this contract at the site of the PROJECT is not protected under Work-
men's Compensation statute, the CONTRACTOR shall provide, and shall cause each
SUBCONTRACTOR to provide, adequate and suitable insurance for the protection of
his employees not otherwise protected.
21.5 The CONTRACTOR shall secure, if applicable, "All Risk" type Builder's Risk In-
surance for WORK to be performed. Unless specifically authorized by the OWNER, the
amount of such insurance shall not be less than the CONTRACT PRICE totaled in the
BID. The policy shall cover not less than the losses due to fire, explosion, hail, light-
ning, vandalism, malicious mischief, wind, collapse, riot, aircraft, and smoke during
the CONTRACT TIME, and until the WORK is accepted by the OWNER. The policy shall
name as the insured the CONTRACTOR, the ENGINEER, and the OWNER.
22. CONTRACT SECURITY
22.1 The CONTRACTOR shall within ten (10) days after the receipt of the NOTICE OF
AWARD furnish the OWNER with a Performance Bond and a Payment Bond in penal
sums equal to the amount of the CONTRACT PRICE, conditioned upon the perform-
ance by the CONTRACTOR of all undertakings, covenants, terms, conditions and agree-
ments of the CONTRACT DOCUMENTS, and upon the prompt payment by the CON-
TRACTOR to all persons supplying labor and materials in the prosecution of the WORK
provided by the CONTRACT DOCUMENTS. Such BONDS shall be executed by the
CONTRACTOR and a corporate bonding company licensed to transact such business
in the state in which the WORK is to be performed and named on the current list of
"Surety Companies Acceptable on Federal Bonds" as published in the Treasury De-
partment Circular Number 570. The expense of these BONDS shall be borne by the
CONTRACTOR. If at any time a surety on any such BOND is declared a bankrupt or
loses its right to do business in the state in which the WORK is to be performed or is
removed from the list of Surety Companies accepted on Federal BONDS, CONTRAC-
TOR shall within ten (10) days after notice from the OWNER to do so, substitute an ac-
ceptable BOND (or BONDS) in such form and sum and signed by such other surety or
sureties as may be satisfactory to the OWNER. The premiums on such BOND shall be
paid by the CONTRACTOR. No further payments shall be deemed due nor shall be
made until the new surety or sureties shall have furnished an acceptable BOND to the
OWNER.
23. ASSIGNMENTS
23.1 Neither the CONTRACTOR nor the OWNER shall sell, transfer, assign or other-
wise dispose of the Contract or any portion thereof, or of his right, title or interest
therein, or his obligations thereunder, without written consent of the other party.

24.1 The CONTRACTOR will indemnify and hold harmless the OWNER and the EN-
GINEER and their agents and employees from and against all claims, damages, losses
and expenses including attorneys' fees arising out of or resulting from the performance
of the WORK, provided that any such claims, damage, loss or expense is attributable to
bodily injury, sickness, disease or death, or to injury to or destruction of tangible prop-
erty, including the loss of use resulting therefrom; and is caused in whole or in part by
any negligent or willful act or omission of the CONTRACTOR, and SUBCONTRAC-
TOR, anyone directly or indirectly employed by any of them or anyone for whose acts
any of them may be liable.
24.2 In any and all claims against the OWNER or the ENGINEER, or any of their
agents or employees, by any employee of the CONTRACTOR, any SUBCONTRACTOR,
anyone directly or indirectly employed by any of them, or anyone for whose acts any
of them may be liable, the indemnification obligation shall not be limited in any way
by any limitation on the amount or type of damages, compensation or benefits pay-
able by or for the CONTRACTOR or any SUBCONTRACTOR under workmen's com-
pensation acts, disability benefit acts or other employee benefits acts.
24.3 The obligation of the CONTRACTOR under this paragraph shall not extend to the
liability of the ENGINEER, his agents or employees arising out of the preparation or
approval of maps, DRAWINGS, opinions, reports, surveys, CHANGE ORDERS, de-
signs or SPECIFICATIONS.
Page 22 of 26
25. SEPARATE CONTRACTS
25.1 The OWNER reserves the right to let other contracts in connection with this
PROJECT. The CONTRACTOR shall afford other CONTRACTORS reasonable oppor-
tunity for the introduction and storage of their materials and the execution of their
WORK, and shall properly connect and coordinate his WORK with theirs. If the proper
execution or results of any part of the CONTRACTOR'S WORK depends upon the
WORK of any other CONTRACTOR, the CONTRACTOR shall inspect and promptly
report to the ENGINEER any defects in such WORK that render it unsuitable for such
proper execution and results.
25.2 The OWNER may perform additional WORK related to the PROJECT by himself,
or he may let other contracts containing provisions similar to these. The CONTRAC-
TOR will afford the other CONTRACTORS who are parties to such Contracts (oar the
OWNER, if he is performing the additional WORK himself), reasonable opportunity
for the introduction and storage of materials and equipment and the execution of
WORK, and shall properly connect and coordinate his WORK with theirs.
25.3 If the performance of additional WORK by other CONTRACTORS or the OWN-
ER is not noted in the CONTRACT DOCUMENTS prior to the execution of the CON-
TRACT, written notice thereof shall be given to the CONTRACTOR prior to starting
any such additional WORK. If the CONTRACTOR believes that the performance of
such additional WORK by the OWNER or others involves him in additional expense or
entitles him to an extension of the CONTRACT TIME, he may make a claim therefor
as provided in Sections 14 and 15.
26. SUBCONTRACTING
26.1 The CONTRACTOR may utilize the services of specialty SUBCONTRACTORS
on those parts of the WORK which, under normal contracting practices, are performed
by specialty SUBCONTRACTORS.
26.2 The CONTRACTOR shall not award WORK to SUBCONTRACTOR (s), in excess
of fifty (50%) percent of the CONTRACT PRICE, without prior written approval of the
OWNER.
26.3 The CONTRACTOR shall be fully responsible to the OWNER for the acts and
omissions of his SUBCONTRACTORS, and of persons either directly or indirectly em-
ployed by them, as he is for the acts and omissions of persons directly employed by
him.
26.4 The CONTRACTOR shall cause appropriate provisions to be inserted in all sub-
contracts relative to the WORK to bind SUBCONTRACTORS to the CONTRACTOR by
the terms of the CONTRACT DOCUMENTS insofar as applicable to the WORK of SUB-
CONTRACTORS and to give the CONTRACTOR the same power as regards terminating
any subcontract that the OWNER may exercise over the CONTRACTOR under any pro-
vision of the CONTRACT DOCUMENTS.
26.5 Nothing contained in this CONTRACT shall create any contractual relation be-
tween any SUBCONTRACTOR and the OWNER.
27. ENGINEERS AUTHORITY
27.1 The ENGINEER shall act as the OWNER'S representative during the construc-
tion period. He shall decide questions which may arise as to quality and acceptability
of materials furnished and WORK performed. He shall interpret the intent of the CON-
TRACT DOCUMENTS in a fair and unbiased manner. The ENGINEER will make visits
to the site and determine if the WORK is proceeding in accordance with the CON-
TRACT DOCUMENTS.
27.2 The CONTRACTOR will be held strictly to the intent of the CONTRACT DOCU-
MENTS in regard to the quality of materials, workmanship and execution of the
WORK. Inspections may be made at the factorv nr fabrication plant of the source of
material supply.
Page 24 of 26
27.3 The ENGINEER will not be responsible for the construction means, controls,
techniques, sequences, procedures, or construction safety.
27.4 The ENGINEER shall promptly make decisions relative to interpretation of the
CONTRACT DOCUMENTS.
28. LAND AND RIGHTS-OF-WAY
28.1 Prior to issuance of NOTICE TO PROCEED, the OWNER shall obtain all land and
rights-of-way necessary for carrying out and for the completion of the WORK to be
performed pursuant to the CONTRACT DOCUMENTS, unless otherwise mutually
agreed.
28.2 The OWNER shall provide to the CONTRACTOR information which delineates
and describes the lands owned and rights-of-way acquired.
28.3 The CONTRACTOR shall provide at his own expense and without liability to the
OWNER any additional land and access thereto that the CONTRACTOR may desire
for temporary construction facilities, or for storage of materials.
29. GUARANTY
29.1 The CONTRACTOR shall guarantee all materials and equipment furnished and
WORK performed for a period of one (1) year from the date of SUBSTANTIAL COM-
PLETION. The CONTRACTOR warrants and guarantees for a period of one (1) year
from the date of SUBSTANTIAL COMPLETION of the system that the completed sys-
tem is free from all defects due to faulty materials or workmanship and the CONTRAC-
TOR shall promptly make such corrections as may be necessary by reason of such de-
fects including the repairs of any damage to other parts of the system resulting from
such defects. The OWNER will give notice of observed defects with reasonable prompt-
ness. In the event that the CONTRACTOR should fail to make such repairs, adjust-
ments, or other WORK that may be made necessary by such defects, the OWNER may
do so and charge the CONTRACTOR the cost thereby incurred. The Performance
Bond shall remain in full f orce and of f ect through the guarantee- period.
30. ARBITRATION (Omitted)

should make his own arrangements with that railway for any new
private crossings required or for the use of any existing private
crossing. All work to be performed by the Contractor on the railway
right-of-way shall be done in a manner satisfactory to the Engineer of
the railway company and shall be performed at such times and in
such manner as not to unnecessarily interfere with the movement of
trains or traffic upon the track of the railway company. The Contractor
shall use all care and precaution in order to avoid accidents, damage,
or unnecessarily delay or interference with the railway company's
trains or other property.
SC-3 Safety Provisions: During excavation, material suitable for backfilling

avoid overloading, prevent slides or cave-ins, and to provide adequate access to the
00232- 1
5/17/93 2676-A
work. The Contractor shall comply with the "Rules and Regulations Governing the
Construction Industry" as promulgated for the Health, Safety, and General Welfare of
Employees by the Commissioner of Labor under General Statutes of North Carolina,
Section 95-131. All adopted standards are included in 13NCAC Subchapter 7C. The
counterpart federal standard is 29 CFR Part 1926 including all revisions and
amendments. Scope as follows:
"The Rules and Regulations shall apply to Trenching, Excavation, Demolition,
Building Construction Work, and all operations pertaining thereto."
a. Particular reference is made to the following paragraphs of Subpart P,
entitled "Excavations":
652. In excavations greater than or equal to 5' in depth, the side of
the excavations shall be shored or braced in accordance with
the applicable regulations unless the sides are sufficiently
sloped to eliminate all possibility of a cave-in.
651.1. Where workmen are engaged near the edge of the
excavation, undercutting of bank or walls is prohibited unless
adequately protected.
651.j. Materials which are excavated shall be placed so that the

excavation or by the use of adequate retaining devices or by
combining both of the above where necessary.
651.c. Proper and adequate means of egress requiring lateral
movements of no more than 25 feet shall be provided at all
times from excavations and trenches that are 4 feet or more in
depth; either by ramps, stairways or ladders. These means of

b. In addition to the Safety Provisions specified herein, the Contractor
shall assume responsibility for and comply with the Department of
Labor Safety and Health Regulations for construction promulgated
under the Occupational and Health Act of 1970 (PL 91-54). Where
the requirements of these acts are in excess of those requirements
specified, the requirements of these acts shall govern. Should the
plans and/or specifications require materials or methods in conflict
with the Safety and Health Regulations, it shall be the responsibility of
the Contractor to request of the Engineer any changes which may be
necessary.
00232 - 2
5/17/93 2676-A
C. Where work is adjacent to street and highways, the Contractor shall
conduct the work in a manner which will avoid the accumulation of
earth from his operations on the traffic areas of the adjacent streets or
roadways. He shall continuously remove such accumulations and
where necessary broom or wet down traffic areas to prevent dust.
d. The General Contractor shall be responsible for overall on-site project
safety.
SC-4 Use of Explosives: The Contractor shall notify the Engineer immediately
when the use of explosives is necessary for the prosecution of the work. The
Contractor shall exercise the utmost care not to endanger life or property and shall be
responsible for any and all damage resulting from the use of explosives. All
explosives shall be stored in a secure manner, in compliance with local laws and
ordinances, and all such storage places shall be marked clearly "DANGEROUS
EXPLOSIVES". Where no local laws or ordinances apply, storage shall be provided
satisfactory to the Engineer and in general not closer than 1000 feet from the road or
from any building or camping area. The Contractor shall notify each public utility
company, having structures in proximity to the site of the work, of his intention to use
explosives and such notice shall be given in sufficient advance to enable the
companies to take such steps as they may deem necessary to protect their property
from injury. Such notice shall not relieve the Contractor of responsibility for any
damage resulting from his blasting operations. Explosives shall be transported,
handled, stored, and used in accordance with Article XVIII of the "Rules and
Regulations Governing Pits and Quarries" as promulgated by the N.C. Department of
Labor.
SC-5 Conflict with Surface Obstructions: The Owner will furnish the Contractor
with all necessary rights-of-way for the prosecution of the work. The rights-of-way
herein referred to are understood to mean only the permission to use and pass
through the location or space in any street or highway, or through any public or private
property in which the Contractor is to construct the work.
a. The Contractor shall not cut, trim or damage in any way any tree or
large shrub along the line of the work without the permission of the
Engineer in each case. The Engineer reserves the right to forbid the
use of any machine or any method of work that, in his opinion, is likely
to cause damage to trees and other vegetation.
b. The Contractor shall be responsible for all poles, posts, fences, or any
other structures or objects existing along the lines of his work within or
without the limits of the excavation. He shall shore or otherwise
support them when necessary and shall repair and make good any
damage caused thereto by his work. All culverts, bridges, curbs and
gutters, driveway entrances, driveways, or other structures or objects
destroyed or disturbed in the execution of the contract shall be
properly repaired or replaced by the Contractor as part of his
obligations under the contract with no direct payment therefore except
as set forth in the Basis of Payment section of these specification.
00232 - 3
5/17/93 2676-A
SC-6 Conflict with Subsurface Obstructions: Care shall be taken not to injure
any gas or water pipe or sewer or drain or service pipes connected therewith or
electric or communication conduits or other underground structures. The Contractor
shall repair or have repaired at once, at his own cost, any public or private structure
damaged by or in the course of his work. The Owner reserves the right to repair any
damage done to sewers, water mains, drain pipes, connections thereto, hydrants,
valves or other structures belonging to the Owner. If the Owner exercises this right, it
will make all necessary repairs, allowing the Contractor full opportunity for inspecting
and checking the cost of the work, and will deduct the actual cost thereof from any
money due or to become due the Contractor. These repairs, whether accomplished by
the Contractor or the Owner, shall include everything necessary to restore the
damaged structure to as good condition in all respects as prior to the Contractor's
work. This may include the use of foundation material where none had been used
before or different materials or types of construction from the original if these should be
necessary to provide a new structure as stable and substantial as the one damaged.
a. Should the location or position of any gas or water pipe, sewer, drain,
conduit or other obstruction within the limits of the trench be such that
it conflicts in line and grade with the pipe or structure being installed
under this contract, or conflicts otherwise so as, in the opinion of the
Engineer, to require its removal, realignment or change in order that
the work under the contract may proceed according to the plans, such
removal, realignment or change will be made without expense to the
Contractor. When, however, such gas or water pipe or other
obstruction shall come within the limits of the excavation for the work
as located by the Engineer, such pipe, conduit or other obstruction
shall be stripped or uncovered by the Contractor, at his own expense,
as constituting a part of this work in excavating. No claim for
damages or extra compensation shall accrue to the Contractor from
the presence of such pipe or other obstruction or from any delay due
to its removal or rearrangement.
b. In case any pipe or other obstruction so located as to interfere with the
work is unexpectedly encountered, the Contractor shall immediately
notify the Engineer of the locality and circumstances and the place
shall be passed over until satisfactory arrangements for avoiding the
conflicts are made without any claim for damages arising from the
delay.
C. The Engineer will, in all cases, by the judge of the necessity or
expedience of any change or rearrangement of any underground
structures which may interfere with the construction of the work.
d. The Contractor shall take all risks and be responsible for all expense
and damage attending the presence or proximity of any gas or water
pipes, sewers, drains, conduits or other underground structures

PART 2 - EXECUTION
2.1 CLEARING OF RIGHT OF WAY
A. The Contractor shall do all clearing necessary for the construction of the
pipe lines. All brush, limbs, stumps and other unusable debris shall be
disposed of by the Contractor at his expense. All excavated rock 3 inches
and larger not used in backfilling shall be hauled off the right of way and
disposed of by the Contractor at his expense. All rights of way shall be
restored to a neat and clean condition prior to acceptance of the work. All
areas disturbed by the Contractor's operations shall be seeded and
mulched and a stand of grass produced.
2.2 TRENCH EXCAVATION
A. General:
1. Pipe lines are shown as near as possible to where they are expected
to be constructed, but the Engineer shall have the right to move the
line, increase or decrease the depth. The Engineer will cooperate with
the Contractor in changing the alignment where the effect on the
Owner will be negligible.
2. Grading shall be done as may be necessary to prevent surface water
from flowing into trenches and any water accumulating therein shall be
removed by pumping or by other approved means.
3. Unless otherwise indicated or specified, excavation shall be open cut
except that short sections of a trench may be tunneled if, in the opinion
of the Engineer, the pipe can be safely and properly installed and
backfill can be properly tamped in such tunnel sections. Trenches
shall of the widths specified hereinafter and of a depth to provide a
minimum cover over the top of the pipe of 3' unless indicated
02221 -1
5/17/93 2676-A
otherwise.
4. The banks of the trench should be as nearly vertical as practicable.
The trench walls above the top of the pipes shall be suitably shored,
braced, or laid back to a stable slope in order to prevent danger to
persons or structures, injurious slides or cave-ins. Shoring, bracing,
and sheeting except as otherwise noted shall be removed as the
trench is backfilled. See applicable section of the Special Conditions.
The Engineer shall have the authority to require that the sheeting be
left in place at no cost to the Owner.
5. Care should be taken not to over excavate. Any excavation below
grade without authorization from the Engineer shall be refilled with
crushed rock at the Contractor's expense.
6. Wherever excavation is in rock, the rock shall be removed to a depth of
at least 4" below the pipe for pipes smaller than 30" diameter and 6" for
pipes of 30" diameter and larger. Before laying the pipe, the trench
shall be refilled to grade with coarse sand thoroughly compacted to
provide proper bedding for the pipe. Loose earth or other material may
be used in lieu of the sand for bedding with the Engineer's approval.
7. Width of Trench: The trench width at the top of the pipe shall be as
narrow as possible but may vary with and depend upon the depth of
trench and the nature of the excavated material encountered, but in
any case shall be of ample width to permit the pipe to be laid and
joined, inspected, and the backfill to be placed and compacted as
hereinafter specified. The maximum clear width of trench shall be not
more than three feet greater than the pipe outside diameter, except by
approval of the Engineer.
8. Trench Bottom: Trench bottom for pipes, except cast iron, ductile iron,
or steel, shall be excavated so that the bottom quadrant for the full
length of the barrel shall be embedded in undisturbed earth or
prepared bedding as the case applies.
9. Excavations shall be reasonably free from water. Provide an effective

2.2 SEWER LINES
A. Clean all sewer lines of debris and sediment.
B. Light Testing:
1. Sewer lines will be checked by the Engineer to determine whether any
displacement of the pipe has occurred (a) after the trench has been
filled to two feet above the pipe and tamped as specified; and (b) upon
completion of the project. The test will be as follows: A light will be
flashed between manholes, or if the manholes have not as yet been
constructed, between the locations of the manholes by means of a
flashlight by reflecting sunlight with a mirror. If the illuminated interior
of the pipe shows any misalignment, displaced pipe, or any other
defects, the defects designated by the Engineer shall be remedied by
the Contractor at his expense.
C. Leakage Testing:

exfiltration tests be performed by the Contractor rather than the
infiltration test. The line under test shall be plugged and filled
with water in such a manner that the maximum hydrostatic head
at any point in the line shall not exceed ten feet of water. All
manholes shall be tested. The exfiltration of the line under test
shall not exceed 200 gallons per inch of nominal pipe diameter
per mile of pipe per 24 hours. The Engineer reserves the right to
require that the lines be tested in sections such that the
maximum allowable static head is imposed on as much of the
line as is practicable. Where a stream is not readily available as
a source of water to use for testing, water from the City system
may be used. Proper notification procedures for operation
valves and hydrants will be required.
3. Test Period: The test period shall be 24 hours, and if the quantity of
infiltration or exfiltration is in excess of the maximum allowable, the
leaking joints shall be relaid if necessary or other remedial
construction shall be performed by and at the expense of the
15042-2

the sewer from infiltration. The Contractor shall be responsible for the
sewer conforming to the above limits for a period of one year from date
of final acceptance.
D. Deflection Test (PVC Pipe and ABS Truss Pipe): Maximum allowable 10
term deflection shall be 5%. As a measure of this, the Contractor shall test
for initial deflection of the pipe no sooner than two weeks nor longer than
one month after installation and backfill. In no case shall the initial deflection
exceed 3% of the pipe diameter. Deflection shall be measured by an
approved "GO-NO GO GAUGE" method or by an approved recording
deflectometer. The Contractor shall have a verified gauge on site prior to the
construction of any sewer lines. All pipes shall be tested by the Contractor
and accepted by the Engineer. No payment shall be approved for untested
pipe. All pipes failing the test shall be removed, or stress relieved to obtain
original shape, re-installed, and retested. All cost 0 the deflection testing
