(March 9, 2026) 23 Project Partnering 24 The Engineer and the Contractor’s Project Manager (PM) will plan and host a Project 25 Partnering workshop as soon as practical after Contract execution. The objective of this 26 Partnering workshop is to promote open lines of communication and teamwork between 27 the Contracting Agency and Contractor staff for the effective completion of the work, and 28 to the standard of quality that will be a source of pride to both the Contracting Agency and 29 the Contractor. Commitments made by both parties shall be memorialized in a Project 30 Partnering Agreement at the conclusion of the Partnering workshop. The Partnering 31 agreement will not affect the terms of the Contract. It is intended only to establish an 32 environment of cooperation and mutual understanding between the parties. 33 The planning and execution of the Partnering process is intended to be a collaborative 35 effort between the Engineer and the PM. The length of the partnering workshop should 36 be commensurate with the size and complexity of the project, and familiarity of the parties. 37 For simple projects an expanded pre-construction meeting may suffice. The partnering 38 workshop may be facilitated by the Engineer, the Engineer and PM, or a mutually 39 agreeable Partnering Facilitator (PF). Selection of a PF, dates and location of the 40 workshops, materials needed for the workshop, frequency and location for follow up 41 meetings, and estimated cost associated with this effort should be discussed and agreed 42 to prior to moving forward with the Partnering process. 43 An initial 1 day (or half day) facilitated Project Partnering workshop is recommended to 45 initiate the partnering agreement. 46 The cost to retain the services of a Partnering Facilitator (if mutually selected as the PF), 48 locate and rent a neutral location to hold the workshop (if held offsite), and any additional 49 materials needed to host the workshop, will be paid by the Contractor. The Partnering 50 Field Guide is available as a resource to the Engineer and PM to assist in the planning of 51 the Partnering session(s) at the following link: 52

The Contracting Agency will reimburse invoice cost for the Contractor provided Partnering 5 Facilitator, facilities and materials at a rate of 50% under the Bid item, “Project Partnering”. 6 After the initial Partnering workshop, quarterly follow-up meetings on projects with over 8 120 working days shall be scheduled to evaluate how the Partnering process is working, 9 acknowledge successes and opportunities for improvement. 10 When the Project Engineer and Contractor’s Project Manager have determined 12 recognition is warranted, the cost for meals and awards for recognition of project 13 partnering success shall be borne by each party. Expenses shall be divided such that 14 each party pays for their pro rata share of the expenses based on the number of people 15 receiving the meal or award. Reimbursement for expenses initially paid by one party will 16 be made to the other party under the Bid item, “Project Partnering”. 17 Payment 19 “Project Partnering”, by calculation. 20 “Project Partnering” will be calculated and paid for as described above. 21

1. Verify the primary horizontal and vertical control furnished by the Contracting 42 Agency, and expand into secondary control by adding stakes and hubs as well 43 as additional survey control needed for the project. Provide descriptions of 44 secondary control to the Contracting Agency. The description shall include 45 coordinates and elevations of all secondary control points. 46

2. Establish, the centerlines of all alignments, by placing hubs, stakes, or marks on 48 centerline or on offsets to centerline at all curve points (PCs, PTs, and PIs) and 49 at points on the alignments spaced no further than 50 feet. 50

4. Establish grading limits, placing slope stakes at centerline increments not more 6 than 50 feet apart. Establish offset reference to all slope stakes. If Global 7 Positioning Satellite (GPS) Machine Controls are used to provide grade control, 8 then slope stakes may be omitted at the discretion of the Contractor 9

5. Establish the horizontal and vertical location of all drainage features, placing 11 offset stakes to all drainage structures and to pipes at a horizontal interval not 12 greater than 25 feet. 13

6. Establish roadbed and surfacing elevations by placing stakes at the top of 15 subgrade and at the top of each course of surfacing. Subgrade and surfacing 16 stakes shall be set at horizontal intervals not greater than 50 feet in tangent 17 sections, 25 feet in curve sections with a radius less than 300 feet, and at 10-18 foot intervals in intersection radii with a radius less than 10 feet. Transversely, 19 stakes shall be placed at all locations where the roadway slope changes and at 20 additional points such that the transverse spacing of stakes is not more than 12 21 feet. If GPS Machine Controls are used to provide grade control, then roadbed 22 and surfacing stakes may be omitted at the discretion of the Contractor. 23

7. Establish intermediate elevation benchmarks as needed to check work 25 throughout the project. 26

8. Provide references for paving pins at 25-foot intervals or provide simultaneous 28 surveying to establish location and elevation of paving pins as they are being 29 placed. 30

9. For all other types of construction included in this provision, (including but not 32 limited to channelization and pavement marking, illumination and signals, 33 guardrails and barriers, and signing) provide staking and layout as necessary to 34 adequately locate, construct, and check the specific construction activity. 35

10. Contractor shall determine if changes are needed to the profiles or roadway 37 sections shown in the Contract Plans in order to achieve proper smoothness 38 and drainage where matching into existing features, such as a smooth transition 39 from new pavement to existing pavement. The Contractor shall submit these 40 changes to the Engineer for review and approval 10 days prior to the beginning 41 of work. 42

The Contractor shall provide the Contracting Agency copies of any calculations and 44 staking data when requested by the Engineer. 45

The Contracting Agency may spot-check the Contractor's surveying. These spot-checks 24 will not change the requirements for normal checking by the Contractor. 25 When staking roadway alignment and stationing, the Contractor shall perform 27 independent checks from different secondary control to ensure that the points staked are 28 within the specified survey accuracy tolerances. 29 The Contractor shall calculate coordinates for the alignment. The Contracting Agency will 31 verify these coordinates prior to issuing approval to the Contractor for commencing with 32 the work. The Contracting Agency will require up to seven calendar days from the date 33 the data is received. 34 Contract work to be performed using contractor-provided stakes shall not begin until the 36 stakes are approved by the Contracting Agency. Such approval shall not relieve the 37 Contractor of responsibility for the accuracy of the stakes. 38
