3.3 Move/Add/Change (MAC), Construction Execution & Commissioning

Key Takeaways

  • Move/Add/Change (MAC) management controls workplace churn, managing employee relocations and furniture adjustments to optimize spatial agility and minimize cost.
  • Construction administration relies on disciplined tracking of RFIs, Submittals, Change Orders, and Punch Lists to enforce quality, cost, and schedule parameters.
  • Substantial Completion marks the milestone where the facility is sufficiently complete for its intended use, shifting building custody, insurance, and warranty periods.
  • Building Commissioning (Cx) is a systematic quality assurance process operating through Pre-Design, Design, Construction, and Occupancy phases to ensure systems perform per owner requirements.
  • Existing building performance is maintained and restored through Retro-Commissioning (Re-Cx) and Continuous Commissioning programs.

3.3 Move/Add/Change (MAC), Construction Execution & Commissioning

The final stages of facility project delivery translate design documents into operational reality. Facility managers must manage construction execution in the field, coordinate Move/Add/Change (MAC) operations for workspace occupants, and enforce comprehensive Building Commissioning (Cx) to verify system performance. Mastery of construction administration controls, MAC churn metrics, and building handover protocols is essential for CFM certification.


1. Move/Add/Change (MAC) Operations & Churn Management

Move/Add/Change (MAC) operations refer to the day-to-day or project-driven relocation of personnel, workstations, technology, and equipment within facility portfolios.

Key Concepts in MAC Management

  • Churn Rate: The percentage of an organization's personnel or workstations that move or are altered within a given year. Churn Rate (%)=(Total Number of Moves / Relocations per YearTotal Building Headcount / Occupants)×100\text{Churn Rate (\%)} = \left( \frac{\text{Total Number of Moves / Relocations per Year}}{\text{Total Building Headcount / Occupants}} \right) \times 100
    • High Churn Industries: Technology, financial services, and consulting firms often experience annual churn rates exceeding 30% to 50%.
  • Types of Moves:
    • Box Move (Individual/Group): Simple relocation of personal effects, computer hardware, and files to existing configured workstations.
    • Project / Departmental Move: Phased relocation of entire divisions, requiring space re-planning, MEP re-configuration, and IT patching.
    • Swing Space Move: Temporary relocation of staff to transitional space while their primary workspace undergoes renovation.

  1. Move Management Software (CAFM / IWMS): Automated ticketing and space management systems track move requests, asset tags, seat assignments, and network port mapping.
  2. IT & Telecom Integration: Coordination of IP telephony, network patch panel re-routing, desktop hardware reconnects, and access control badge permissions prior to Day 1 occupancy.
  3. Move Communication & Logistics: Providing move kits, color-coded box labels, crate deliveries, and clear move-instructions to employees to prevent lost assets.
  4. Day-One Post-Move Support: Deploying "Help Desks" or move champions on the first business day following a move to immediately address missing peripherals, ergonomic adjustments, or key card issues.

2. Construction Administration & Quality Controls

During physical construction, the facility project manager acts as the owner's representative, monitoring the general contractor (GC) and design team to ensure contract compliance.

Administrative ControlPurpose & Operational Mechanics
Request for Information (RFI)Formal query submitted by the GC to the architect/engineer seeking clarification on drawing inconsistencies, field obstructions, or specification ambiguities. Must be answered promptly to avoid schedule claims.
Submittals & Shop DrawingsDetailed fabrication drawings, product data sheets, and physical samples submitted by trade subcontractors for design team approval prior to material fabrication or installation (e.g., air handler shop drawings, carpet samples).
Change Orders (CO)Formal contract modifications that alter project scope, contract cost, or completion schedule. Must be reviewed, negotiated, and approved by the FM prior to work execution to prevent unauthorized budget drift.
Application for Payment & RetainageMonthly billing submitted by the GC based on percentage of completion. The FM typically retains 5% to 10% (Retainage) from each progress payment until final project completion to ensure punch list performance.

  1. Substantial Completion: The stage in the progress of work when the facility (or designated portion) is sufficiently complete in accordance with contract documents so that the owner can occupy or utilize it for its intended use.
    • Significance: Marks the formal end of liquidated damages, shifts insurance liability and utility costs to the owner, and triggers the start of statutory equipment warranty periods.
  2. Certificate of Occupancy (CO): Official permit issued by the local Authority Having Jurisdiction (AHJ / Building Inspector) certifying that the building complies with applicable building, fire, and health codes and is safe for human occupancy.
  3. Punch List Inspection: A joint walkthrough by the FM, architect, engineer, and GC to identify minor non-conforming work, cosmetic defects, or incomplete items (e.g., missing wall plates, scratched paint, uncalibrated thermostats). Items are documented on a punch list that the GC must complete prior to final payment.
  4. Final Closeout & Acceptance: Submission of options and maintenance (O&M) manuals, warranty certificates, attic stock materials, finalized as-built drawings (BIM models), and full release of contractor retainage.

3. Building Commissioning (Cx)

Building Commissioning (Cx) is a systematic quality assurance process that verifies and documents that all building systems and assemblies are designed, installed, tested, and operated to meet the Owner's Project Requirements (OPR).

Commissioning Across Project Phases

PhaseKey Commissioning Activities
Pre-Design PhaseDevelop the Owner's Project Requirements (OPR) document; select the Commissioning Authority (CxA).
Design PhaseCreate the Basis of Design (BOD) document; conduct Cx design reviews; write Cx specifications into bid documents.
Construction PhaseInspect installation of commissioned equipment; review shop drawings; conduct pre-functional checklists.
Occupancy & Acceptance PhasePerform Functional Performance Testing (FPT) under full operational loads; train O&M staff; deliver final Cx report.
Post-Occupancy PhaseConduct 10-month seasonal testing prior to warranty expiration; resolve latent operational defects.

Specialized Commissioning Types

  • Retro-Commissioning (Re-Cx): A commissioning process applied to existing buildings that have never been commissioned. Identifies operational improvements, baseline energy waste, and control sequence corrections without major capital equipment replacement.
  • Re-Commissioning: Commissioning an existing facility that was previously commissioned, performed periodically (e.g., every 3-5 years) to restore systems to optimal operating efficiency.
  • Continuous (Ongoing) Commissioning: An ongoing process using automated fault detection and diagnostics (AFDD) software integrated with Smart Building IoT sensors to continuously monitor and optimize system performance.
