(March 9, 2026) 3 Project Partnering 4 The Engineer and the Contractor’s Project Manager (PM) will plan and host a Project 5 Partnering workshop as soon as practical after Contract execution. The objective of this 6 Partnering workshop is to promote open lines of communication and teamwork between 7 the Contracting Agency and Contractor staff for the effective completion of the work, and 8 to the standard of quality that will be a source of pride to both the Contracting Agency and 9 the Contractor. Commitments made by both parties shall be memorialized in a Project 10 Partnering Agreement at the conclusion of the Partnering workshop. The Partnering 11 agreement will not affect the terms of the Contract. It is intended only to establish an 12 environment of cooperation and mutual understanding between the parties. 13 The planning and execution of the Partnering process is intended to be a collaborative 15 effort between the Engineer and the PM. The length of the partnering workshop should 16 be commensurate with the size and complexity of the project, and familiarity of the parties. 17 For simple projects an expanded pre-construction meeting may suffice. The partnering 18 workshop may be facilitated by the Engineer, the Engineer and PM, or a mutually 19 agreeable Partnering Facilitator (PF). Selection of a PF, dates and location of the 20 workshops, materials needed for the workshop, frequency and location for follow up 21 meetings, and estimated cost associated with this effort should be discussed and agreed 22 to prior to moving forward with the Partnering process. 23 An initial 1 day (or half day) facilitated Project Partnering workshop is recommended to 25 initiate the partnering agreement. 26 The cost to retain the services of a Partnering Facilitator (if mutually selected as the PF), 28 locate and rent a neutral location to hold the workshop (if held offsite), and any additional 29 materials needed to host the workshop, will be paid by the Contractor. The Partnering 30 Field Guide is available as a resource to the Engineer and PM to assist in the planning of 31 the Partnering session(s) at the following link: 32 https://wsdot.wa.gov/publications/fulltext/construction/WSDOTProjects-Partnering-34 FieldGuide.pdf 35

The Contracting Agency will reimburse invoice cost for the Contractor provided Partnering 37 Facilitator, facilities and materials at a rate of 50% under the Bid item, “Project Partnering”. 38 After the initial Partnering workshop, quarterly follow-up meetings on projects with over 40 120 working days shall be scheduled to evaluate how the Partnering process is working, 41 acknowledge successes and opportunities for improvement. 42 When the Project Engineer and Contractor’s Project Manager have determined 44 recognition is warranted, the cost for meals and awards for recognition of project 45 partnering success shall be borne by each party. Expenses shall be divided such that 46 each party pays for their pro rata share of the expenses based on the number of people 47 receiving the meal or award. Reimbursement for expenses initially paid by one party will 48 be made to the other party under the Bid item, “Project Partnering”. 49 Payment 51 “Project Partnering”, by calculation. 52 https://wsdot.wa.gov/publications/fulltext/construction/WSDOTProjects-Partnering-FieldGuide.pdf https://wsdot.wa.gov/publications/fulltext/construction/WSDOTProjects-Partnering-FieldGuide.pdf
