Owners Requirements

Owners need help defining their needs

We can help

Get in early - During Predesign

Attend meetings during Schematic Phase

Attend more than one meeting

Be an active member of the team

Write the OPR for the owner


5/43


6/43

Owners Requirements

Have a Core Values party

Participants should Include:

Owner User Group Members and Leaders

Maintenance staff

Architect / Engineer

Contractors / CM

Plan for to full day, for the exercise


7/43

Owners Requirements

Participants are educated

We get "buy in"

Educational process accelerated

Decisions verified Adversity diminished

Nuances of organization learned

Design process expedited

Remember: The OPR is anon technical document,that describes what needsto happen for the Owner to

call this project a success.

No details on this project address

acoustical corrugated decking

While this detail does

not show it, there is

batts insulation required

under the decking

Acoustical decking allows air to pass into

building on both sides of the corrugations

Batts insulation wont seal the ends,

only filter the air

reign to do as much or as little as they want

Cx Specifications

Were not the designers but we can help

Cx spec writing is more than writing Cx

specs

Review Division 1 specs

Review Mechanical specs

Review Electrical specs

Review / Write / Edit Cx Specs


16/43

Cx Specifications

Request electronic specifications in

electronic format, i.e. MS Word, Word Perfect

Edit specs with Track Changes

Return electronic specs to designer, for

review and approval

Engineer or Architect-of-record owns the

specs, we are only making suggestions


17/43

Cx Specifications

Review Division 1 specs: Review submittal requirements

Add submittal requirements for Commissioning

Review O&M Requirements, modify submittal date to be justafter submittal approval

Review payment application requirements

Tie payment application to completion of checklist tracking

form

Review substantial completion requirements

Tie Cx completion to substantial completion

Write Division 1 Cx Requirements Spec


18/43

Cx Specifications

Review Mechanical Specs:

Edit general requirements to reference Cx

Edit Controls specs

Review quality assurance requirements to be more

Cx friendly

Tighten-up contractor qualifications

List specific individuals assigned to project

Temporary programming / global commands

Trending requirements / memory availability

20/43

Bidding

Cx Plan needs to be specific enough toprovide guidance but open enough forupdating

Cx Plan should mirror the specrequirements

Keep it short, 15 to 20 pages plus

diagrams Define flow of Cx Process, documentation,

et cetera. Use Flow diagrams

WHAT MAKES OUR DOCUMENTATION

DIFFERENT?

Resolution oriented rather than blame oriented


42/43


WHAT DEFICIENCIES DO YOU BRING TOTHE CLIENT? All? Cost impact ones? Design ones? Construction

ones? Long Term ones?

Are all logged issues actually deficiencies?

HOW DO WE GET RESOLUTION? Participate or pull away?

Resolve during or after discovery?

Get Client involved?

Can we reduce the number or deficiencies or time ittakes to resolve them?
