Technology System Commissioning & Sign-Off
Technology commissioning proves that installed systems meet agreed functional requirements under normal, abnormal, and recovery conditions. It is more than confirming that devices power on. We create test scripts from the contract documents, verify prerequisites, witness or execute authorized checks, record evidence, and manage deficiencies through retest before issuing a bounded report.
The process can cover structured cabling records, managed networks, WiFi, 4K AV, NVR surveillance, automation, lighting and shade interfaces, and related integrations. Acceptance criteria are established before testing so outcomes are repeatable and disputes do not depend on subjective impressions. Sign-off identifies what passed, what was accepted as an exception, what remained outside scope, and the configuration tested.
What we deliver
- Commissioning plan defining systems, responsibilities, prerequisites, test environment, acceptance criteria, evidence, schedule, and exclusions
- Pre-functional review of power, labels, cable reports, firmware, controller access, configuration backups, and approved submittals
- Managed-network checks for topology, VLAN behavior, addressing, PoE delivery, uplink state, approved firewall rules, and restart recovery
- WiFi validation using agreed coverage areas, client types, roaming observations, channel plan, interference conditions, and measured results
- Surveillance tests for camera view, day/night behavior, time synchronization, recording, retention settings, event search, export, and authorized remote access
- AV and automation scripts exercising 4K source routing, HDCP behavior, audio zones, Dolby Atmos layouts where included, scenes, schedules, and control interfaces
- Deficiency log with unique identifiers, objective evidence, severity, responsible party, target milestone, disposition, and retest result
How we approach it
We translate owner requirements, specifications, control narratives, submittals, and approved changes into a commissioning matrix. Each requirement is connected to a test method and expected result. Responsibilities are explicit: who supplies instruments, who operates the system, who may change configuration, who corrects deficiencies, and who has acceptance authority. Integrated tests are sequenced around permanent power, ISP activation, lighting loads, shades, doors, and other dependencies. Safety, privacy, and access constraints are documented before cameras, networks, or occupied areas are tested.
Detailed scripts specify starting conditions, user role, command or stimulus, expected response, evidence, and recovery step. Configuration baselines are captured so a failed test can be investigated without uncontrolled changes. Network scripts examine segmentation and intended access rather than attempting unauthorized penetration testing. Automation scripts verify individual commands and complete sequences, including behavior after controller or network restart. Surveillance scripts use approved scenes and retention settings. Any test data or accounts created for commissioning are tracked for removal or transfer at closeout.
Pre-functional checks confirm the system is ready to test: field labels reconcile, reports are available, devices are mounted, permanent power is stable, firmware and configuration are identified, and installers have completed their own startup. Deficiencies discovered at this gate are returned to the responsible contractor before integrated testing.
Functional tests are run in the approved sequence and recorded as pass, fail, blocked, or not applicable—never converted to a pass without evidence. Failures receive a reproducible description and are retested after the responsible party reports correction. Where changes affect related functions, regression tests are added. The final report summarizes tested versions and conditions, includes the closed deficiency record, and clearly lists accepted exceptions or deferred work. Sign-off confirms performance against this defined scope; it does not replace permits, code inspections, manufacturer warranties, or another professional’s sealed design.
Frequently asked questions
Who should define the commissioning acceptance criteria?
Criteria should derive from the owner’s requirements and contract documents, with input from the designer, GC, installers, IT team, and owner representative as appropriate. The party holding contractual acceptance authority approves them. GGIS can convert requirements into measurable scripts and identify gaps, but should not invent a stricter or looser obligation after bids are awarded. Agreeing on criteria before startup makes deficiencies easier to diagnose and close.
What happens when a system passes alone but fails during integration?
The issue is logged against the integrated sequence, with evidence showing starting conditions and the point of failure. The team then isolates dependencies such as network reachability, driver versions, control feedback, timing, HDCP negotiation, or third-party account permissions. Correction ownership follows the contract scope, not whichever technician happens to be present. After repair, the failed sequence and related regression tests are repeated so a local fix does not conceal a downstream problem.
Is cable certification the same as system commissioning?
No. Cable certification evaluates installed links against a defined cabling standard and test limit using suitable instruments. Commissioning verifies that complete systems satisfy functional requirements. A certified Cat6A link can still connect to a misconfigured switch port, and a network device may appear operational over a link that lacks required certification evidence. Good closeout uses both when specified, while keeping the acceptance basis and report type for each clear.
