SECTION 01160 — SITE CONDITIONS
PART 1 - SITE INVESTIGATIONS AND REPRESENTATION
1.01 General Investigations
A. The Contractor acknowledges that he has satisfied himself as to the nature and location of the work, the
general and local conditions, particularly those bearing upon access to the site; handling, storage, and
disposal of materials; availability of water, electricity and roads; uncertainties of weather, or similar
physical conditions at the site; the conformation and conditions of the ground; the equipment and
facilities needed preliminary to and during the execution of the work; and all other matters which can in
any way affect the work or the cost thereof under this Contract.
1.02 Soil Conditions
A. The Contractor further acknowledges that he has satisfied himself as to the character, quality and
quantity of surface and subsurface materials to be encountered from his inspection of the site and from
reviewing any available records of exploratory work furnished by the Owner or included in these
Documents. Failure by the Contractor to acquaint himself with the physical conditions of the site and
all the available information will not relieve him from responsibility for properly estimating the
difficulty or cost of successfully performing the work.
1.03 Contractor Representation
A. The Contractor warrants that as a result of his examination and investigation of all the aforesaid data
that he can perform the work in a good and workmanlike manner and to the satisfaction of the Owner.
The Owner assumes no responsibility for any representations made by any of its officers or agents
during or prior to the execution of this Contract, unless (1) such representations are expressly stated in
the Contract, and (2) the Contract expressly provides that the responsibility therefore is assumed by the
Owner.
PART 2 - INFORMATION ON SITE CONDITIONS
2.01 General
Any information obtained by the Engineer regarding site conditions, subsurface information,
groundwater elevations, existing construction of site facilities, and similar data will be available for
inspection, as applicable, at the office of the Engineer upon request. Such information is offered as
supplementary information only. Neither the Engineer nor the Owner assumes any responsibility for
the completeness or interpretation of such supplementary information.
A. Differing Subsurface Conditions:
In the event that the subsurface or latent physical conditions are found materially different from
those indicated in these Documents, and differing materially from those ordinarily encountered and
generally recognized as inherent in the character of work covered in these Contract Documents, the
Contractor shall promptly, and before such conditions are disturbed, notify the Owner in writing of
such changed conditions.
2. The Engineer will investigate such conditions promptly and following this investigation, the
Contractor shall proceed with the work, unless otherwise instructed by the Engineer. If the
Engineer finds that such conditions do so materially differ and cause an increase or decrease in the
cost of or in the time required for performing the work, the Engineer will recommend to the Owner
the amount of adjustment in cost and time he considers reasonable. The Owner will make the final
City of Fort Collins SECTION 01160 — SITE CONDITIONS
Park Planning & Development Division Page 1 of 3
decision on all Change Orders to the Contract regarding any adjustment in cost or time for
completion.
B. Underground Utilities:
Known utilities and structures adjacent to or encountered in the work are shown on the Drawings.
The locations shown are taken from existing records and the best information available from
existing utility plans, however, it is expected that there may be some discrepancies and omissions
in the locations and quantities of utilities and structures shown. Those shown are for the
convenience of the Contractor only, and no responsibility is assumed by either the Owner or the
Engineer for their accuracy or completeness.
PART 3 - CONTRACTOR'S RESPONSIBILITY FOR UTILITY PROPERTIES AND SERVICE
3.01 General
A. Where the Contractor's operations could cause damage or inconvenience to railway, telegraph,
telephone, television, oil, gas, electricity, water, sewer, or irrigation systems, the operations shall be
suspended until all arrangements necessary for the protection of these utilities and services have been
made by the Contractor.
B. Notify all utility offices which are affected by the construction operation at least 48 hours in advance.
Under no circumstances expose any utility without first obtaining permission from the appropriate
agency. Once permission has been granted, locate, expose, and provide temporary support for all
existing underground utilities.
C. The Contractor shall protect all utility poles from damage. If interference of power poles, telephone
poles, guy wires, or anchors are encountered, notify the Owner's Representative and the appropriate
utility company at least 48 hours in advance of construction operations to permit the necessary
arrangements for protection or relocation of the interfering structure.
D. The Contractor shall be solely and directly responsible to the Owner and operators of such properties
for any damage, injury, expense, loss, inconvenience, delay, suits, actions, or claims of any character
brought because of any injuries or damage which may result from the construction operations under this
Contract.
E. Neither the Owner nor its officers or agents shall be responsible to the Contractor for damages as a
result of the Contractor's failure to protect utilities encountered in the work.
F. If the Contractor while performing the Contract discovers utility facilities not identified in the
Drawings or Specifications, he shall immediately notify the Owners and the utility in writing.
G. In the event of interruption to domestic water, sewer, storm drain, or other utility services as a result of
accidental breakage due to construction operations, promptly notify the proper authority. Cooperate
with said authority in the restoration of service as promptly as possible and bear all costs of repair. In
no case shall interruption of any water or utility service be allowed to exist outside working hours
unless prior approval is granted.
H. The Contractor shall replace, at his own expense, any and all other existing utilities or structures
removed or damaged during construction, unless otherwise provided for in these Contract Documents
or ordered by the Engineer.
3.02 Interfering Structures
A. Take necessary precautions to prevent damage to existing structures whether on the surface,
aboveground, or underground. An attempt has been made to show major structures on the Drawings.
The completeness and accuracy cannot be guaranteed, and it is presented simply as a guide to avoid
known possible difficulties.
City of Fort Collins SECTION 01160 - SITE CONDITIONS
Park Planning & Development Division Page 2 of 3
3.03 Field Relocation
A. During the progress of construction, it is expected that minor relocations of the work will be necessary.
Such relocations shall be made only by direction of the Owner's Representative. If existing structures
are encountered that prevent the construction, and that are not properly shown on the Drawings, notify
the Owner's Representative before continuing with the construction in order that the Owner's
Representative may make such field revision as necessary to avoid conflict with the existing structures.
If the Contractor shall fail to so notify the Owner's Representative when an existing structure is
encountered, and shall proceed with the construction despite the interference, he shall do so at his own
risk.
3.04 Easements
A. Easements and permits will be obtained by the Owner where portions of the work are located on public
or private property Easements will provide for the use of the property for construction purposes to the
extent indicated on the easements. Copies of these easements and permits are available upon request to
the Owner. It shall be the Contractor's responsibility to determine the adequacy of the easement
obtained in every case and to abide by all requirements and provisions of the easement. The Contractor
shall confine his construction operations to within the easement limits or make special arrangements
with the property owners or appropriate public agency for the additional area required. Any damage to
property, either inside or outside the limits of the easements provided by the Owner, shall be the
responsibility of the Contractor as specified herein. The Contractor shall remove, protect, and replace
all fences or other items encountered on public or private property. Before final payment will be
authorized by the Owner's Representative, the Contractor will be required to furnish the Owner with
written releases from property owners or public agencies where side agreements or special easements
have been made by the Contractor or where the Contractor's operations, for any reason, have not been
kept within the construction right-of-way obtained by the Owner.
B. It is anticipated that the required easements and permits will be obtained before construction is started.
However, should the procurement of any easement or permit be delayed, the Contractor shall schedule
and perform the work around these areas until such a time as the easement or permit has been secured.
3.05 Land Monuments
A. The Contractor shall notify the Owner's Representative of any existing Federal, State, Town, County,
and private land monuments encountered. Private monuments shall be preserved, or replaced by a
licensed surveyor at the Contractor's expense. When Government monuments are encountered, the
Contractor shall notify the Owner's Representative at least two (2) weeks in advance of the proposed
construction in order that the Owner's Representative will have ample opportunity to notify the proper
authority and reference these monuments for later replacement.
