NEW BUILDING Cx

• QUESTION:– Does the Corps of Engineers perform New Building Cx

for our customers on MILCON projects?

• Answer??– A. Yes– B. No– C. Maybe

What is New Building Commissioning (Cx)?Cx is a quality assurance process for buildings frompre-design through design, construction, andoperations. It involves achieving, verifying, anddocumenting the performance of each system to meetthe building's operational needs within the capabilitiesof the documented design and equipment capacities,according to the owner's functional criteria.Commissioning includes preparing and enhancingbuilding documentation and training operation andmaintenance personnel. The result should be fullyfunctional systems that can be properly operated andmaintained throughout the life of the building.(ASHRAE, 2004)

We define the basic purpose ofcommissioning as follows: "The basicpurpose of building commissioning is toprovide documented confirmation thatbuilding systems function in compliancewith criteria set forth in the ProjectDocuments to satisfy the owner'soperational needs." This definition isbased on the critical understanding thatthe owner must have some means ofverifying that their functional needs arerigorously addressed during design,construction and acceptance.

NEW BUILDING Cx PROCESS

• QA process including the following phases– Pre-design– Design– Construction– Operations.

• Verify & Document performance– Building systems– Train O&M staff– Provide fully functioning systems

CORPS PROCESS• Project initiation & plan development

– Planning Charrette• Produce Draft 1391

– Workload analysis– Initiate project in P2– Verify 1391– Develop Project Management Plan (PMP)

• Establish Project Delivery Team (PDT)– Dev. Milestones & activities

• Develop Acquisition Plan• Develop Resource Estimates

– Request P&D funds

CORPS PROCESS

• Design Process– Advertise, Evaluate Proposals and Select A-E– In house pre-design activities

• Verify project scope• Initial tasking & funding document• Pre-design conference• Baseline budget & schedule• Request & Receive funds

CORPS PROCESS• Project definition

– Notice to proceed– Design charrette

• ECB 2002-13• AR 415-15• DA PAM 190-51• TI’s 800-01 & 802-01• ER 1110-3-1300

– Develop concept design– Submit estimate

CORPS PROCESS• Project definition (Continued)

– Engineering Tech review– Construction BCOE– User Functional review– VE– Coordinate comments– Revise concept design– Pay A-E– Authorize final design

CORPS PROCESS

• Final design & D-B RFP Development– Receive directive & funds– Issue NTP– Develop final design– Develop source selection plan– Submit pre-final design– Prepare final RFP

CORPS PROCESS

• Final design & D-B activities (Continued)– Tech review– BCOE review– Functional review– Coordinate comments

• Revise final design– Develop Special Clauses

• Submit Final 3086– Back check– Ready To Advertise (RTA)

CORPS PROCESS

• Advertising and award– Authority to advertise– Fed Biz Oops announcement– Advance notice to bidders– Receive bids

• Evaluate Bids• Conduct pre-award survey

– Receive proposals• Conduct source selection

– Develop award CWE– Request funds and authority to award– Award

CORPS PROCESS

• Construction– Precon– NTP– QA/QC & safety plans– Schedule review and accept– Submittals– Construction placement– Progress payments

CORPS PROCESS• Construction (Continued)

– Process mods– Red zone (Performance Documented)

• Testing complete or on schedule• Tab done• HVAC commissioning complete/on schedule• Test reports complete

– Prefinal inspection– Punch list– Final inspection
