What it is

What MissionStart actually does

A dedicated startup team that embeds with your construction, commissioning, and OEM partners. We coordinate and witness startup and commissioning, write the procedures, build the asset data, and staff the ramp with experienced operators — then hand the building over clean.

Why it matters

Day one should feel like day one thousand.

The weeks around energization are the most expensive in a facility's life. A missed sequence, an untrained crew, or a turnover package no one can use turns into downtime, warranty fights, and months of catching up. Getting that window right protects the capital already in the ground — and sets the cost of running the building for the next decade.

ECLOSEOUT PLATFORM

One closeout registry — every site, every phase, every trade.

Closeout records live in a dozen places: as-builts in an inbox, TAB reports in a binder on site, warranty dates in someone's spreadsheet. By the time operations needs a record, nobody knows which folder it's in — or whether it's the final version. eCloseout is our own platform that holds every handoff record in one structured place, organized by site, by phase, and by trade, with live status on what's open, in progress, and accepted.

Commissioning complete ≠ operations ready. Every setpoint, sequence, alarm limit, and known deficiency recorded as-left.

Organized by trade, not one generic list
Mechanical, electrical, plumbing, general, and specialty each get their own checklist — arc-flash studies and NETA testing under electrical, TAB and startup reports under mechanical.
As-left, not as-designed
Every item carries notes on what actually changed during commissioning — a revised transfer delay, a new alarm limit, a re-staged sequence — so operations inherits reality, not design intent.
Live completion status
Open → In Progress → Accepted → N/A on every item, with a real completion gauge per site. No more guessing what's left before turnover.
Asset register tied to the checklist
Model, serial, and location captured once per asset — the anchor point for warranty claims, PM scheduling, and the CMMS build.
One contact directory per site
Engineers, subcontractors, the commissioning agent, and OEM field reps grouped by role — so an after-hours warranty issue doesn't turn into inbox archaeology.
Scales site by site
Every new building starts from the same five categories and the same checklist logic. Add the next site in one click instead of rebuilding the structure.
Built to hand over

Commissioning complete ≠ operations ready.

A turnover package is only worth what operations can use. eCloseout carries the documentation, asset data, and open punch straight into the operating program — so the team running the building day to day starts with a complete record instead of a box of binders.

What we do

The services inside MissionStart

We don't have to self-perform the wrench work to make it succeed. MissionStart supports and staffs startup, commissioning, and re-commissioning — owner's-side coordination, qualified people on site, and documentation that actually lands — plus whatever mission is specific to your facility.

01

Startup support

Equipment-level activation, backed by us. OEMs and contractors perform their startups; we coordinate, witness, staff the support roles, and make sure every chiller, AHU, pump, tower, and VFD is energized correctly, documented, and warranty-protected.

  • OEM and vendor startup scheduling and coordination
  • Owner's-side witnessing and pre-start verification
  • Support technicians and escorts staffed on demand
  • Startup reports captured, filed, and punch tracked to closure
02

Commissioning support

Systems-level proof, with people to run it. We support your CxA and trades through functional performance testing and integrated systems testing — supplying the hands, tracking, and owner's representation that keeps the schedule honest.

  • Pre-functional checklists and installation verification
  • Test support staffing for FPT and integrated systems testing
  • BAS points, graphics, alarms, and TAB integration oversight
  • Issues log driven to resolution before turnover
03

Re-commissioning support

For buildings already running. We staff and lead the effort to re-test existing systems and recover performance lost to overrides, failed sensors, broken sequences, and schedules that quietly got turned off.

  • Trend and BAS review to find drift
  • Override, sensor, and valve verification
  • Sequence correction coordinated with your controls partner
  • Energy and uptime gains documented
04

Your mission

Anything outside the standard scope. We learn your facility first — systems, people, and constraints — then build a plan around the goal you're actually chasing.

  • Facility walkdown and systems assessment
  • Staffing, training, or documentation gaps filled
  • Custom scopes for one-off projects
  • Ongoing support once the goal is met
Outcomes

What you walk away with

Measurable results your team owns long after we hand over.

  • Startup and commissioning supported and witnessed on the owner's side
  • Trained crews ready before energization
  • Documented systems, procedures, and asset registries
  • Reduced risk during the highest-stakes weeks
