Switchgear & MCCs
Installation, rigging, alignment, and termination of medium- and low-voltage lineups up to 38 kV. Factory-witness testing supported.
Z1 Electrical designs, builds, and commissions the electrical backbone of refineries, data centers, and manufacturing plants — from 15 kV switchgear to the last terminated conductor.
Eight core disciplines, one integrated crew. Every scope is planned, estimated, and executed by field-hardened supervision — not subcontracted out.
Installation, rigging, alignment, and termination of medium- and low-voltage lineups up to 38 kV. Factory-witness testing supported.
LOTO planning, tie-in choreography, and 24/7 crew rotations that hit re-energization windows without the last-minute punch list.
Pad, dry-type, and unit substations from receipt to acceptance — including oil handling, meggering, and TTR reporting.
UPS, static transfer switches, PDU builds, and hot-aisle rough-in for hyperscale and colo — sequenced around commissioning gates.
Coordination, short-circuit, and arc-flash analysis with labeling and PPE-boundary rollouts that stand up to audits.
Pre-commissioning walkdowns, motor rotation checks, protective-relay function testing, and first-power sequencing.
DCS/PLC field wiring, fiber pulls, loop checks, and IO panel builds — coordinated with your automation vendor of record.
Primavera P6, DCMA-14 checks, resource-loaded schedules, and daily field productivity feedback loops.
A snapshot of active and recently completed scopes across refining, manufacturing, and mission-critical.
Four gates, one accountability chain. The general foreman who bids the work is the one running it in the field.
Constructability review with the crew that will actually build it. Line-item labor and materials.
Resource-loaded P6 schedule, LOTO strategy, and rigging plans — before mobilization.
Daily productivity tracking, weekly earned-value, and photo-documented QC hold points.
Commissioning, punch, and handover packages that pass client audits on the first pass.
Z1 was founded on a simple idea: heavy industrial electrical work is a craft, and the best way to deliver it is to keep the estimating, planning, and field leadership under one roof.
Our supervisors have run switchgear installs at Gulf Coast refineries, wired hyperscale data-center halls, and turned around motor loads on 12-hour shutdown windows. We hire journeymen who've done the work — not resumes.
Send us your drawings, one-lines, or a rough scope. We'll return a constructability review and a range estimate within five business days.
