1.10 GENERAL
Sections in these specifications titled "Common Work for . . ." shall apply to all following
subsections whether directly referenced or not.
Sections in these specifications titled "Related Sections" shall be read as integral to the
specification as if they were fully detailed within. All work and materials described in such
sections shall be provided and performed by the Contractor.
1.10.16 Definitions
Approximate: Generally as shown or described, but has not been verified, or may require
adjustment. No level of accuracy is implied or should be assumed.
Calculation(s): When the contract documents require the Contractor to provide calculations,
those calculations must be prepared and stamped by a Professional Engineer licensed to
practice in the State where the project is constructed or where components requiring
calculations are fabricated.
Construction Limits: The area within which the Contractor is allowed to perform their
activities. If not specifically labeled as such on the plans, the Construction Limits are the
Owner's property, Owner's easements, or permitted public right of way upon which the
project facilities are to be constructed.
Diameter: The nominal diameter classification common for the type of material and purpose.
Should not be assumed to represent the actual measured inside nor outside diameter unless
specifically identified as such.
Engineer: When used in the context of project design or oversight it means the design
engineer (RH2 Engineering) or the Owner's staff engineer. When used in the context of an
engineer employed by the Contractor or an engineer required by a specification it means a
person licensed as a Professional Engineer in the State in which this project is constructed, or
for a product or system the state where it is fabricated/assembled.
Or Equal (Or Approved Equal): An alternate product, assembly, or method that the
Owner's Representative has reviewed based on information provided by the Contractor and
determined to provide functional equivalence, or better, than that specified. Such
determination does not relieve the Contractor from responsibility should the product,
assembly, or method fail to perform as needed.
Owner's Representative: Person(s) authorized by the Owner to observe the work, administer
the contract, approve tests, make decisions, and otherwise act as an agent of the Owner. The
terms Engineer, Owner's Observer, Owner's Inspector, and Owner are generally
interchangeable with the term Owner's Representative.
Proposed: The word refers to work that is part of the Contract, to be performed by the
Contractor. The word "proposed" does not need to show up to indicate work by the
Contractor. Unless work is specifically noted to be performed by others, all work is to be
performed by the Contractor.

Provide: When used in context of the Owner "providing" items (such as materials, water,
equipment, etc.), "provide" means that the items are available, but it is the Contractor's
responsibility to pick up, haul, off-load, secure, manage, install, test, make provisions for, and
perform all work necessary that is not specifically noted as being performed by the Owner.
When used in context of the Contractor "providing" items, it means all materials and work
necessary unless stated otherwise.
The following location designations shall be used except where otherwise noted on the plans:
Dry Locations: Indoor continually dry areas including office, laboratory, blower, and
electrical rooms.
Wet Locations: All locations exposed to the weather, whether under a roof or not, or within
channels, basins or tanks.
Damp Locations: Process areas; areas containing pumps, valves, and major piping; all spaces
wholly or partially underground, or having a wall or ceiling forming part of a channel or tank,
unless otherwise designated on the Plans. Any areas which do not fall within the definitions
for dry, wet, or corrosive shall be considered damp.
Corrosive Locations: Areas where chlorine gas under pressure, sulfuric acid, or liquid
polymer are stored or processed, sewer wetwells and sewer manholes.
Immersed or Submerged Locations: Areas which are periodically, or continuously
submerged in, or contain a liquid.

1.20 PRICE AND PAYMENT PROCEDURES
1.21.55 Cost Increases for Materials
There will be no allowance for additional payment should the cost of any materials go up
during the original contract timeframe. The Contractor is responsible for securing prices at
the time of bid.
1.25.00 Substitution Procedures
Any product or construction method that, in the opinion of the Owner, does not meet these
specifications will be considered a substitution. Substitutions must be approved prior to
incorporation into the project. The Owner has the right to reject any request for substitution.
Incomplete requests will not be reviewed.
Requests shall include an explanation of why the request is being made along with drawings,
details, specifications, and samples sufficient to allow the Owner to evaluate the proposed
substitute. Requests shall include any change necessary in construction methods with a detailed
description and related drawings of the proposed methods. Provide an itemized comparison
of each proposed substitution with the specified product or method. If the Contractor believes
there are no variations from the bid documents, include a statement to that fact in the request
for substitution.
In making a request for a substitution, the Contractor represents that they have investigated
the proposed product or method and has determined that it provides equal or superior form
and function to the product specified. The Contractor shall coordinate incorporation of
accepted substitutions into the work, making changes that may be required for the work to be
completed.
The Contractor waives all claims for additional costs and time related to substitutions. The
Owner reserves the right to charge the Contractor for the Owner's time required for
incorporating the substitution into the work which may include but not be limited to
observation, requests for information, and commissioning.
No guarantee is made that product model numbers included in the specifications or on the
plans are current at the time of bidding. The bidder shall provide pricing in their proposal for
current versions of discontinued models. If the bidder is uncertain of the correct replacement
model, or feels there is a price discrepancy, the bidder shall request a substitution following
the requirements of section 1.25.13.10 Substitutions Prior to Bid Opening. Requests for price
increases after award will not be accepted.
1.25.13.10 Substitutions Prior to Bid Opening
Before opening bids, the Owner may consider written requests from product suppliers or
prime bidders for substitutions. All requests for substitution must be received by Owner a
minimum of 5 working days prior to bid opening. Approval of substitutions will be only by
addendum. The bidder shall include in their proposal all costs for any modifications required
to adopt the substitute.

1.25.13.15 Substitutions After Contract Execution
After contract execution, the Owner will consider requests for a substitution of products or
methods in place of those specified. Submit electronically, or two hard copies of each request
for a substitution. Submit requests early enough for the Owner to review the request without
affecting the schedule. The Owner will review with reasonable promptness and will provide a
response within 10 working days after receipt of all information required for the review, unless
the complexity of the proposed substitution requires, in the Owner's sole opinion, additional
review time.
If the Owner approves a request for substitution, and the Contractor subsequently requests
an alternate substitution for the same or similar work, the Owner reserves the right to charge
the Contractor for the costs required to review the alternate substitution.
