(1) If any delay in issuance of notice to proceed or in construction following an award of any public construction contract is primarily caused by acts or omissions of persons or agencies other than the contractor and a preliminary, special or permanent restraining order of a court of competent jurisdiction is issued pursuant to litigation and the appropriate public contracting body does not elect to delete the completion of the contract as provided by RCW
60.28.011(7), the appropriate contracting body will issue a change order or force account directive to cover reasonable costs incurred by the contractor as a result of such delay. These costs shall include but not be limited to contractor's costs for wages, labor costs other than wages, wage taxes, materials, equipment rentals, insurance, bonds, professional fees, and subcontracts, attributable to such delay plus a reasonable sum for overhead and profit.
In the event of a dispute between the contracting body and the contractor, arbitration procedures may be commenced under the applicable terms of the construction contract, or, if the contract contains no such provision for arbitration, under the then obtaining rules of the American Arbitration Association.
If the delay caused by litigation exceeds six months, the contractor may then elect to terminate the contract and to delete the completion of the contract and receive payment in proportion to the amount of the work completed plus the cost of the delay. Amounts retained and accumulated under RCW
60.28.011 shall be held for a period of forty-five days following the election of the contractor to terminate. Election not to terminate the contract by the contractor shall not affect the accumulation of costs incurred as a result of the delay provided above.
(2) This section shall not apply to any contract awarded pursuant to an invitation for bid issued on or before July 16, 1973.
