UNIT PRICES:
A. The following schedules of unit prices shall be filled out and submitted as part of the
Proposal. Failure to fill in all unit prices may result in disqualification of Bidder.
1. Contractor must fill in unit prices for all Work Items for any particular project
being bid.
B. Unit prices stated by Bidder shall include all materials and Work installed and
completed in place in accordance with all applicable portions of the Drawings and
Specifications, and shall include all costs associated with such items including, but not
limited to: materials, labor, supervision, overhead, and profit for General Contractor
and/or subcontractors, general conditions, permits, shoring, and other related items.
C. The quantities stated in the Bid Schedule are approximate only and are prepared for
comparison of Bids. Each Bidder is responsible for verifying all quantities and shall
base his Bid thereon. Payment to the Contractor will be made only for the actual
quantities of Work accepted and performed in accordance with the Contract unit prices.
D. Contractor shall not exceed stated Base Bid quantities without prior written approval
from Owner/Engineer. Note: Contractor will not receive payment for un-authorized
Work performed (Base Bid or Alternates) that exceeds stated Bid quantities. The
Owner reserves the right to delete one or more line items contained within the Work
Item Schedules, and/or to increase or decrease stated quantities, to best meet the
Owner's requirements.
E. Also, at the discretion of the Owner, the quantities of Work to be performed for each
Work Item (Base Bid or Alternate) shall be reviewed and approved by the WSU PM
prior to beginning Work, and may be decreased or increased throughout the Project.
Refer to Section 020010 for specific Work Item requirements.
F. In the event of a math error occurring on a submitted Bid, (i.e., stated unit price
multiplied by stated quantity does not equal stated extension) stated unit price shall be
considered basis for Bid to calculate extension.
G. INCREASED OR DECREASED WORK ITEM QUANTITIES:
1. Owner/Engineer shall have right under Contract to make increases and
decreases in quantities and changes in plans, as may be necessary to ensure
completion of contemplated work subject to following qualifications:
2. As used herein, major item is defined as any item whose total cost, determined
by multiplying Bid quantity and Contract unit price, is equal to or greater than 5%
of original total Contract price. All other items are considered minor items and
are not subject to unit price adjustment.
3. Where cost of final work prior to consideration of adjustment is within 5% of
original total contract price, or if amount of adjustment is less than $100, or if item
is exempted from such adjustment elsewhere in Contract, no adjustment in
Contract unit prices will be considered for any increased or decreased quantities.

4. Where cost of final work has increased more than 5% of original total Contract
price prior to consideration of any adjustment, requests for adjustments will be
considered on following basis:
5. Where quantity of an item of work required to complete project is not increased
nor decreased from original estimate by more than 25%, payment for quantity of
said item will be made at Contract unit price.
6. Where quantity of any major item of work is increased by more than 25%, then
unit price for quantity of that item of work over 125% of original Contract quantity
will be decreased by 10% of unit price bid.
7. Where quantity of any major item of work is decreased by more than 25%, then
adjusted unit price will be obtained by multiplying Contract unit price for that item
of work by factor obtained as follows:
Factor = 1 + (0.10 (P-C))/C
Where:
P = Contract Quantity
C = Constructed Quantity
8. In no case shall product of adjusted unit price and number of units of work
performed exceed product of Contract unit price and 75% of original contract
quantity. Neither will unit price be adjusted to more than twice original Contract
unit price.
