Service · 05
I/O buildings, inside and out.
Local Instrument Rooms, marshalling cabinets, MCCs, panelboards, HVAC interlocks, and the cable management that keeps it serviceable for decades.
01
What's in scope
The work, in detail.
I/O buildings and Local Instrument Rooms are where the field meets the control system. They have to be clean, traceable, and easy to maintain for the next 30 years.
MCC installation
Set, anchor, bus-tie, and wire Motor Control Centers. Bucket installation and labeling per single-line.
Panelboards and switchboards
Lighting and small power panelboards, distribution panels, and tie-in to the building service.
Marshalling cabinets
Terminal blocks for field instrument cables. Tagged per loop sheet, dressed for serviceability.
Cable tray and conduit
Overhead tray for instrument and power separation, with bend radii and separation per NEC.
HVAC and lighting
Building HVAC tie-ins, classified-area lighting where required, and emergency lighting circuits.
Grounding
Building steel bonding, equipment grounding, and isolated reference ground for instrumentation where the DCS spec requires it.
02
Deliverables
Turnover documentation.
As-built building single-line.
MCC bucket schedule with as-installed settings.
Marshalling cabinet tag-to-terminal cross-reference.
Megger and ground tests for distribution and feeder cable.
Lighting and HVAC commissioning records.
Building closeout binder with manufacturer drawings.
03
Process
How this service runs.
01
Building drawing review
Compare the as-shipped building layout against the design drawings. Coordinate with the building manufacturer.
02
Pre-install
Anchor bolts, conduit stub-ups, grounding stub-ups, and HVAC penetrations.
03
Equipment install
MCCs, panelboards, and marshalling set, anchored, and bonded.
04
Cable termination
Field cable pulled, terminated, and labeled. Test each circuit before energization.
05
Commissioning
Lights up, HVAC running, building energized, and a closeout walk with your facility engineer.
In the field
The work is documented, the loops close, the inspector signs.

FAQ
Common questions on this scope.
Both. We work with pre-fab building suppliers on the inside fit-out, and we handle full site-built scope when the design calls for it.
Yes. Set, anchor, bus-tie, terminate, and label. We do not paint over the manufacturer's tags or bucket labels.
Yes. Old MCC out, new in, with pre-staging and outage planning. Coordinated with relay engineering for any setting changes.
Per IEEE 1100 and the DCS supplier's spec, with separate reference ground when called for and bonding back to the building ground.
Less common but handled. Pressurization, purge control, and classified-area wiring methods inside the building envelope.
