Select and appoint the Commissioning Provider

After reading this guide, you will be able to procure and appoint an independent Commissioning Provider before design begins. You will know how to run a qualifications-based selection and lock in a contract that gives your CxP enforceable authority to direct testing and withhold sign-off.

Purpose of the step

This ‘how to’ is part of the ASHRAE Stage 1 series. It supports Step 1 of the Pre-Design commissioning process.

For the full Stage 1 overview, see the Stage 1 guideline.

The purpose of Step 1 is to appoint a qualified, independent Commissioning Provider at the start of the pre-design stage, before the project programme is set, the design brief is issued, and the design team is engaged. Standard 202-2024, Section 5.1.1 assigns CxP selection as an Owner responsibility at project initiation. Guideline 0-2019, Section 5.2.1 governs the CxP's appointment requirements, independence obligations, and authority over the commissioning process.

In practical terms, this step ensures that:

✅ The CxP is in place before any commissioning-shaping decisions are made.

✅ The selection is conducted through a structured two-stage process—an RFQ to shortlist on qualifications, followed by an RFP for proposals and fee—ensuring technical capability is evaluated before cost is considered [Guideline 0-2019 Informative Appendix E].

✅ The CxP's independence from the design and construction entities is validated and confirmed [Guideline 0-2019 Informative Appendix L Sections L2.2–L2.4].

✅ The Professional Services Agreement [PSA] gives the CxP authority to direct testing, require remediation, and withhold sign-off [Guideline 0-2019 Section 5.2.1]. Without that authority written into the contract, the CxP can observe and report. They cannot enforce.

✅ All pre-conditions for Step 2 are met; the CxP is contracted, in position, and ready to form the commissioning team.

Inputs and Outputs

Required Inputs

Expected Outputs

Owner decision to proceed with the project and initiate commissioning

Signed Professional Services Agreement: scope, deliverables, schedule, and authority across all project stages

Preliminary project concept; building type, approximate size, functional use, site context, and indicative programme

Formal CxP appointment letter issued before Pre-Design work begins

Initial commissioning scope thinking: systems to be commissioned, applicable regulatory drivers, any LEED or green building certification requirements

Independence declaration or, where a conflict exists, a formal conflict of interest register and management plan

Owner's procurement framework: approved process for professional services selection, authority levels for contract execution

Verified shortlist record: scored evaluation against

Identified Owner's Representative or Project Manager with authority to run the procurement process

Named key individual confirmed in contract, with substitution clause and required notice period

Step Checklist

Shortlisting criteria record completed before the RFQ is issued: minimum individual qualifications and comparable project experience thresholds defined, formatted as a dated one- or two-page table, and retained in the Stage 1 procurement file.
Two-stage selection process completed: RFQ shortlist established on qualifications alone; RFP issued to shortlisted firms; technical proposals and fee proposals evaluated separately.
Shortlisted candidates interviewed, with the project team who will lead the Cx work present at the interview.
Proposals scored against the recommended 100-point framework, with a documented record for each firm
Reference checks completed using the multi-party contact lists submitted, including construction manager and facilities administrator contacts, not only Owner contacts.
CxP holds recognized professional certification [e.g., CCP, BCxP, or equivalent under ISO/IEC 17024]
CVs of named alternate personnel reviewed and confirmed adequate for project scale and programme.
CxP confirmed independent from the designer of record and construction management firm; independence verified at organisational level, not only declared
Where a conflict of interest exists [e.g., the CxP shares a parent company with the designer], it is formally documented, organizationally separated, and a management plan is in place before the PSA is signed.
Signed separate Professional Services Agreement [PSA] in place with the Owner: scope, deliverables, schedule, and authority defined across all project stages.
Authority clause confirmed as enforceable: CxP has express authority to direct testing, reject non-compliant results, and withhold commissioning sign-off until remediation is verified
Named key individual written into the contract with a substitution clause specifying required notice period and Owner approval process.
CxP appointed at the initiation of the project. Practically, this means the appointment is complete before the project programme is set, the design brief is issued, and the design team is engaged.

How to

Section 4 covers the full procurement and appointment sequence across seven sub-steps.

Work through them in order: timing and the conditions that must be in place before the RFQ goes out.

Quick reference:

4a: Establish when the appointment must happen

4b: Independence verification before the selection

4c: Structure and run the two-stage selection process

4d: Define and review the RFP submission requirements

4e: Compare fee proposals where divergence exists

4f: Execute the Professional Services Agreement [PSA]

4g: Confirm pre-conditions for Step 2

The most damaging version of Step 1 is one that happens too late. We consistently see CxPs appointed at Design Development, sometimes later, and asked to work backwards against a design that is already substantially fixed.

This happens because "project initiation" is often misunderstood as the start of design rather than the start of project planning, leaving the CxP to inherit a brief they had no part in setting.

To prevent this, the CxP appointment must be sequenced as the very first project activity, this will ensure that the CxP can actually govern the Pre-Design stage.

Confirm that the CxP appointment is initiated before any of the following occur: the project programme is set; the design brief is issued; the design consultant is engaged.
Begin informal market conversations early, as by the time a project is formally declared, the most capable commissioning firms may already be committed elsewhere.
Confirm that the Owner's Representative or Project Manager has the authority, experience and mandate to run a formal selection process and execute a Professional Services Agreement. If delegated authority is unclear, resolve it now, before the RFQ is issued. If it is determined that there is not enough commissioning experience in the team to do the work then look to employ some support from an experienced company.
Document this timing decision as the opening entry in the Step 1 record: date project initiation was declared, and confirmation that no design brief, designer engagement, or programme-setting activity will proceed until the CxP appointment is complete.

What to Watch

"Project Initiation" is treated as the date the design consultant submits their first drawing, not as the date the commissioning procurement process should already be underway. By that point, Step 1 has already failed.

Common Issues

IssuesWhat it looks like in practiceWhy it causes trouble

Late appointmentCxP is engaged during Design Development or first noted in the design team's appointment. The project programme, design brief, and consultant RFP are already complete.The CxP inherits every substantive pre-design decision without having shaped any of them. The OPR reflects what the design team assumed, and the Cx scope reflects what the procurement team allowed for. Neither is recoverable.

Fee-led selectionProposals are evaluated with fee weighted equally to or ahead of qualifications. The lowest-fee submission is awarded without a scope alignment check.The cheapest proposal arrives with testing phases scoped out, design review cycles reduced, and O&P services excluded. The gap surfaces at handover when there is no budget, no programme, and no contractual basis to deliver what the project needs.

Independence asserted, not verifiedThe CxP's E6 submission declares independence. The organisational structure is not checked.The CxP is nominally independent. Their firm shares a parent company with the designer of record or has a standing sub-consultant relationship with the construction manager. The conflict surfaces after appointment, when it is commercially awkward to resolve.

Authority clause diluted to observer roleContract language reads: "the CxP will monitor testing activities and report findings." The word "authority" does not appear.Contractors learn in the first month that the CxP produces reports. They price the risk of commissioning requirements accordingly. The CxP cannot require remediation; they can only escalate to the Owner, who is then placed in a dispute with the contractor.

Named individual not in contractThe PSA names the firm. The key individual who won the appointment moves to another project six months in.The project is assigned a junior lead with none of the experience the evaluation was based on. The Owner has no contractual basis to object.

Two-stage process collapsed to single RFPThe market is "well known" or the timeline is compressed, so a combined RFQ/RFP is issued. Fee is included from day one.Fee influences shortlisting before qualifications have been properly weighted. Generic responses from firms without directly relevant experience are included on merit of price. The scored outcome is legally defensible and practically weak.

PSA not signed before Pre-Design beginsThe procurement decision is made, the appointment letter is issued, and Pre-Design work begins. The PSA is still being negotiated.The CxP attends meetings, contributes to documents, and establishes working relationships with no signed contract defining their scope, authority, or deliverables. The negotiation that follows happens after leverage has been given away.

Evaluation panel not pre-briefedScorers receive proposals and apply the E7 rubric individually without prior calibration.The evaluation produces widely divergent scores for the same proposal. The selection is averaged rather than assessed. What the panel intended to reward and what they actually reward are different things.

Timing and sequencing

Step 1 begins at the point the project is identified and the Owner decides to proceed. It continues until the Professional Services Agreement [PSA] is executed and the Commissioning Provider [CxP] is formally in position. The appointment must be complete at the initiation of the project. This means it must happen before any Pre-Design commissioning work begins, and therefore before any of the following occur: the project programme is set, the design brief is issued, or the design consultant is engaged.

Earliest start: At initial project identification, before the procurement of any other consultants or the establishment of the master project programme.
Latest acceptable start: Before the design brief is issued. Any later and the CxP inherits decisions they should have shaped.
Dependencies: Step 1 has no commissioning predecessor; it opens at project identification. However, it is the absolute predecessor to every other Pre-Design step. Step 2 cannot begin until the PSA is signed and the CxP is formally appointed.
Market awareness: Informal conversations with CxP firms can and should begin before Step 1 is formally opened; often 6 to 12 months ahead of formal procurement on complex projects; to confirm market capacity before the RFQ limits options.
Execution hard stop: The PSA must be signed before the CxP attends any Pre-Design meeting or contributes to any Pre-Design document. The procurement decision is not the starting point; the executed contract is.
