ROLE BEFORE CONTRACTOR SELECTION

Assist in Contractor Selection:

Develop Scoring Criteria for Contractor and Major Subs

Assist in Developing Scope for RFP on Selection of CM

Tracking Back to OPR and BOD on Criteria for Contractor Selection

Providing Constructability Input to the Design Team for Design Documents

Site Issues

Mobilization

Temporary Utility Service Input


LESSONS LEARNED PRE-DESIGN

Choosing project delivery methods Meets not defeats project expectations

Cx process is applied differently to each delivery method

Bring Commissioning Authority on early in project development stage

Qualified, independent, 3rd party CxA Not Owner, Project Manager, Design Team, Contractor Team, TAB Team


BENEFITS

Pro-active, early understanding of local permitting process and requirements

Understanding of potential effects to existing facility operations

Better match of project delivery method to the project requirements

Well documented OPR forms the basis for all future project decisions.

BASIS OF DESIGN GUIDELINES

The Basis of Design Phase is required with each design submission and should include the following:

a. System and assembly options

b. System and assembly selection reasoning

c. Facility, system, and assembly performance assumptions

(i) Assumptions for calculations/sizing.

(ii) Analytical procedures and tools

(iii) Environmental conditions

h. Consultant, engineering, and architectural guidelines for design developed by the design team or others.


BASIS OF DESIGN GUIDELINES

The Basis of Design documents how each criterion in the Owners Project Requirements is implemented in the design. For any criterion that could not be met, documentation detailing what was done, its impact on the Owners Project Requirements, and how the Owners Project Requirements was modified shall be included.


LEED REQUIREMENTS PROJECT SCORECARD

Periodic walk-through. Report findings to CxA

Normal per contract.

Found in the Division 01 9100 Specifications


LESSONS LEARNED

CxA not brought in early enough to provide input on design at the early stages

CxA did not participate in incorporating Cx requirements into Construction Documents

Owner should include requirements in the contract with the design team to cooperate with the Commissioning Authority

Make sure the BOD is created and documents how criteria in OPR is implemented in the design

The Commissioning plan should be incorporated in the design documents


BENEFITS

Early documentation of Cx requirements provides knowledge to all the team members of the Cx process

Incorporating these Cx requirements into the bid documents provides contractors the opportunity to incorporate them into their scope

Reduces added cost claims by contractors who want to say they did not understand requirements

Provides a basis for tracking design back to the OPR to eliminate scope creep and to manage expectations by users and operations personnel

Table of Contents

1. Executive Summary

2. Commissioning Overview, Approach, and Team Information

3. Commissioning Scope Information

4. Project Information- Overview and Systems

5. Results and Conclusions


LESSONS LEARNED

More involvement and team collaboration on start-up and pre-functional testing

Allow proper time for commissioning before owner move in

Where project is tied to existing facility allow for testing and plan for mitigating effects on existing systems

Capacity and condition of utility services to CHP facility must be anticipated and designed to meet requirements of system at all loading conditions and SOPs

Better understanding of the environmental and permitting requirements and how they effect schedule, cost and testing sequences

More consistent and cooperative involvement by both design and construction teams with systems testing

Pay attention to the details and be proactive

Get rid of negative attitude about commissioning


BENEFITS

Improved Success For Functional Tests due to more complete startup and pre-functional test.

More Cost effective and successful integrated testing without interruption of the Facility at Move In.

This will allow for more fully tested facility and an integration into the existing facility

Minimize permitting and regulatory issues and reduce time of design and construction

More integration testing with existing facility allows for a cohesive efficient operation.

LESSONS LEARNED

Early review of Measurement and Verification measures to determine building usage trends and energy consumption.

Re-Commissioning of Systems should be planned on appropriate intervals

Handover and training meeting should be held to discuss any issues to be aware of and special considerations on operations

Systems Manual review with team should be performed and not just a handover of the documents.

Plan this handover process early, early and get it into the schedule

THE ISSUE

The USGBC has taken the recognized Cx Process as established and published by the

BCA

AGC

ASHRAE

ASHE

GSA

and divided the process into what they deem Fundamental (only 10 steps of the usual 39) which are required then choose another 10 steps (for a total of 20 out of 39) as an option.

This is an established process that works best when it remains together

They are sending the message that the established whole multi-step process can be boiled down to just a few of the steps, and any remaining steps can be purchased as extra optional steps


IN OTHER WORDS

LEED Fundamental does not equal industry recognized commissioning Without design and submittal reviews, Owners are only getting acceptance testing NOT

Commissioning

Even LEED Enhanced does not provide full service commissioning

By only requiring LEED Fundamental, Owners are not reaping the full benefits of commissioning No Design Review

No Submittal Review

No Services Past FPT

Forced to accept what the designers and installers give them (Isnt this where we came in?)

LEED is diluting the Commissioning Industry By contracting Acceptance Testing instead of Commissioning LEED is confusing the issue and

giving Owners a false sense of assurance


THE IMPACT

Owners unfamiliar with industry standards who contract for fundamental only ARE NOT RECEIVING COMMISSIONING SERVICES! But they think they are.

By dividing the Cx process and relegating critical steps to Enhanced, Owners not familiar with Commissioning may think they can either do without, or these are extra steps when they are in fact an integral part of the process!

USGBC is misrepresenting the Cx Industry by splitting the Cx process, making part required and part additional. When in fact this is one multi-step process that has a logical order that builds on the previous step.

USGBC is trying to amend this issue with their revised latest version of LEED where they are adding requirements for energy performance measurement and measurement & verification plans that would no longer be optional
