90 Day Startup

The First 90 Days Make or Break Your Job: A Builder’s Start-Up Checklist

The projects that go sideways almost never go sideways at the end. They go sideways at the start. Mobilize sloppy and you spend the rest of the job catching up chasing permits you should have had, relocating a staging yard that was put in the wrong place, explaining to the owner why the project is already behind. Mobilize tight and the job has a rhythm before the first wall goes up.

The first 90 days set the tone for everything that follows. Not because the early work is glamorous it is contracts, permits, dirt, toilets, and meetings but because the unglamorous stuff is exactly what protects the schedule, the budget, and the people who will build the project. The contractors who start jobs well are the ones who built their start-up into a checklist, gave every line item an owner and a due date, and refused to advance until the work was actually done.

Why the Start-Up Window Matters

Think about where money and time leak out of a job. It is rarely one big catastrophe. It is a hundred small gaps the COI that was not on file when the sub showed up, the utility nobody potholed, the dust permit that was not posted when the inspector rolled by, the staging yard placed for convenience instead of for flow. Every one of those is a “we thought you were handling that” conversation waiting to happen. And every one of them is preventable with a checklist and an owner assigned to each line.

The rule that governs all of it: assign an owner and a due date to every single item, and do not advance a phase until its items are closed. A checklist without accountability is just a wish list.

Phase 1: Contracts, Insurance, and Authorization

Before anybody mobilizes, lock down the paperwork that authorizes the work and protects the company. Confirm the contract is fully executed and all bonds payment, performance, and maintenance where required are issued with the correct amounts and dates. Verify the Notice to Proceed is in hand and the dates match the schedule. Pull every Certificate of Insurance for the GC and all subs and confirm the owner is named as additional insured. Request sub COIs 30 days ahead, because processing always takes longer than expected.

Then hold the pre-construction meeting with the owner. This is where scope boundaries, exclusions, allowances, and owner-furnished items get aligned. Nail down how RFIs, submittals, change orders, and pay applications will route and what the expected turnaround time is. Agree on the schedule of values, billing cycle, and retainage. Identify who on the owner’s side can actually make decisions and what their authority limits are. Finally, send a formal mobilization and impact notice: start date, working hours, haul routes, and any closures. Copy the neighbors and tenants who will feel the noise and the access changes. Nobody likes a surprise jobsite next door.

Phase 2: Permits, Authorities, and Utility Locating

This is the phase that keeps people out of trouble legal trouble and the kind where a backhoe goes through a gas line. Get salvage permits in place and plan protection of anything being preserved. Post every permit where required before the relevant work begins: building, grading, dust control, and all trade permits. In Arizona, the Maricopa County Dust Control Permit and plan must be posted on site before any dust-generating activity, and the SWPPP and Notice of Coverage need to be at site entry before ground disturbance. Coordinate pre-construction meetings with the building department, fire marshal, and public works, and confirm inspection request procedures and lead times for every trade before the first inspection is needed.

Then comes the underground. Call Blue Stake it is the law. In Arizona, that is Arizona 811, filed at least two full working days before digging, with the dig area white-lined first. Do not break ground until a positive response has been received from every member utility. Pull the 811 markings, the owner as-builts, and the survey data into one controlled utility map. Pothole every crossing and conflict point so exact location and depth are known not estimated. Identify every critical shut-off for gas, water, and electric, tag them, confirm they operate, and put them in the emergency plan. A strike that gets prevented is a strike nobody ever hears about. That is the goal.

Phase 3: Site Mobilization and Temporary Facilities

Now the physical jobsite gets stood up. Order signs, start-up consumables, and safety gear. Get the project sign, emergency contact board, regulatory postings, and wayfinding in place gates, delivery entrance, visitor check-in, muster points, one-way routes. Set up the trailer with internet, computers, a plotter, phones, and two-way radios, and get document control and daily-log systems running from day one. Schedule the trailer install pad, leveling, tie-down, ADA stairs or ramp and arrange temporary power, water, and communications. Place restrooms, hand-wash stations, and dumpsters sized to peak crew, and begin building the permanent worker bathrooms so the temporary units can be phased out.

Set up parking with safe pedestrian routes that keep people away from moving vehicles. And establish the staging yard based on the sequence of work, not convenience. Stage for flow, not for what is easy to reach from the gate. Plan delivery access, crane and forklift reach, and material flow before the first load arrives. When equipment is ordered or rented, time it tight to the work. Every idle rental day is money out of the budget. Inspect each unit on arrival, note any damage before signing the receipt, confirm operator certifications, and log every piece with its daily cost and return date.

Phase 4: Site Preparation and Early Works

Clear, control, and stabilize under the environmental controls already in place. Stand up dust suppression before clearing starts. In Maricopa County, the permit and posted plan are required once a tenth of an acre is disturbed. Get water trucks, stabilized entrances, and track-out control running before any clearing begins. Install SWPPP best management practices before disturbing soil perimeter controls, inlet protection, stabilized entrance, concrete washout and set the inspection schedule, including the within-24-hours-of-a-quarter-inch-rain trigger. Clear and grub within marked limits, protecting what stays. Run demolition confirming asbestos notification and clearance before touching any structure and stabilize disturbed areas so dirt does not get lost in the first storm. Make safe: lock out de-energized services, cap abandoned lines, barricade open excavations.

Phase 5: Safety Start-Up and Orientation

This is where culture gets set. Day one, not day thirty. Get the safety start-up kit on site and build a job-specific safety plan tailored to this project’s hazards not a generic binder. In Phoenix-area heat conditions, heat-illness prevention goes directly into that plan. Build the emergency action plan with muster points, evacuation routes, the nearest hospital, and emergency contacts. Then hold pre-install meetings with the first trades to walk scope, sequence, quality expectations, and coordination points before running the all-hands safety kickoff that sets the tone for the whole project. Every worker gets oriented before they begin including crews who have worked on previous projects attendance is documented, and stickers are issued. No exceptions. Stand up daily documentation and job-cost tracking from the very first hour. When costs get away early, they rarely come back.

The core items every safety start-up kit must include:

• PPE, first aid supplies, AED, and fire extinguishers staged and accessible before the first crew arrives.
• Orientation stickers, barricades, tape, cones, and lockout/tagout supplies on hand from day one.
• Job-specific emergency action plan posted at site entry with muster points, evacuation routes, nearest hospital, and all emergency contacts confirmed current.
• Heat-illness prevention plan including water, shade, rest schedule, and acclimatization protocol active before first day in elevated temperatures.

Phase 6: Operating Systems and Production Rhythm

A mobilized site is not the goal. A running site is. This final phase turns the jobsite into a production system. Launch daily foreman huddles short, same time, same place covering the day’s tasks, handoffs, the safety focus, and the constraints that need clearing. Establish the weekly planning cadence: a look-ahead to surface and remove constraints, commitment planning, and tracking how much of the plan was actually completed and why anything missed was missed. Tie all of it back to the master schedule and the production plan.

The weekly rhythm that keeps every project on track:

• Monday: Team weekly tactical coverage confirmed, PTO coordinated, hot items assigned, no gaps in field support.
• Tuesday or Wednesday: Strategic planning and procurement meeting macro Takt plan reviewed, long-lead items tracked, supply chain confirmed against production dates.
• Weekly: Trade partner tactical look-ahead walked, roadblocks surfaced and owned, weekly work plan commitments locked.
• Daily afternoon: Foreman huddle next day planned, resources confirmed, worker huddle agenda built before the crew arrives.

That rhythm daily and weekly, every week, from the first day of production through the last zone is what carries a job from a clean start to a clean finish. If your project needs superintendent coaching, project support, or leadership development, Elevate Construction can help your field teams mobilize correctly, build in flow from day one, and run a production system that protects the schedule, the budget, and the people. We are building people who build things, and the builders who start jobs well are the ones whose finish lines hold.

A Challenge for Builders

Print this checklist before the next project mobilizes. For every item in every phase, write one name next to it not a department, not a role, one name and a due date. Review it in the pre-construction meeting with the team and confirm every item has both. Then do not advance from Phase 1 to Phase 2 until Phase 1 is closed. The first 90 days are the cheapest place on the whole project to fix a problem. Spend them deliberately.

As Marcus Aurelius says, “The first step: before all else, to be prepared.”

On we go.

Frequently Asked Questions

Why is staging the yard for flow rather than convenience so important during mobilization?

Because the staging decisions made in the first week determine how materials, equipment, and crews will move through the site for the entire project. A staging yard placed for what is easiest to reach from the gate creates material flow conflicts and logistics problems that compound with every phase. Relocating staging mid-project costs double the time and money it would have taken to plan it correctly at the start.

Why must every permit be posted before the relevant work begins rather than as quickly as possible afterward?

Because inspectors do not give credit for after-the-fact compliance. An inspector who arrives to check dust control before the Maricopa County permit is posted does not wait they issue a stop-work order. The cost of posting a permit correctly is nothing. The cost of a stop-work order, a NOV, and lost production days is substantial. Permits go up before the work they authorize begins, without exception.

What does it mean to orient every worker before they begin, including experienced crews?

It means every person who steps onto the jobsite receives a site-specific safety orientation covering this project’s hazards, emergency procedures, muster points, stop-work authority, and site rules before performing any work. Experience on previous projects does not substitute for orientation on this one the hazards, layout, and rules differ on every site. Attendance is documented and the orientation sticker is issued. No exceptions, no shortcuts.
