GC-to-Security Handoff — The Houston Jobsite Protocol

Site plan with ingress, high-value zones, and neighbor-sensitive corners marked. High-value asset registry — what is stored where and its rough value tier. After-hours contact tree — 3-deep with role and authority. Access schedule — who is expected on-site outside standard hours and how they identify. Weekly reporting cadence — who reads the incident summary and on what day.

Guardtress ships templates for all five; the GC fills in and signs before deployment.

A single primary vehicle ingress with a gate. Pedestrian access through the same gate during working hours. Any secondary ingress locked and posted as 'emergency only.'

Every legitimate after-hours visitor is announced to the monitoring center by name and expected time. Undeclared arrivals get the standard talkdown challenge.

• Single primary vehicle ingress
• Pedestrian same-gate during hours
• Secondary ingress locked + posted
• After-hours visitors announced by name

Responsible — the monitoring center for detection and dispatch; the GC superintendent for on-site remediation; Guardtress deployment lead for technology issues.

Accountable — Guardtress account manager (single point).

Consulted — insurance broker on any material incident.

Informed — owner, project manager, and site safety officer on weekly summary.

Every Monday by 10am, the GC superintendent and PM receive: (1) 7-day incident summary, (2) LPR anomaly list, (3) any recommended posture adjustments, (4) upcoming holiday or high-risk window flags.

The report takes 5 minutes to read and prevents the '30 days of no communication' pattern that erodes trust.

• Monday 10am: 7-day incident summary
• LPR anomaly list
• Recommended posture adjustments
• Upcoming risk-window flags

Standard Guardtress deployments across the Houston metro land in 24–72 hours from signed quote to live monitoring. A single solar-powered mobile security trailer covers roughly 1.5–2 acres of open ground, carries 5–7 days of no-sun autonomy, and runs on bonded cellular so it needs no site power, no trenching, and no permanent mounting. Units relocate with a standard pintle hitch as the work front moves — a real advantage on phased Houston builds where the exposure point changes every few weeks.

Every unit ships with license plate recognition (LPR), analytic tripwires tuned to human and vehicle shapes, and two-way talkdown from a live U.S.-based monitoring center. Verified events escalate to the Houston Police Department or the Harris County Sheriff's Office as a confirmed crime in progress, which moves the call up the priority queue instead of into the false-alarm pile. Site plans, camera angles, and escalation contacts are set during a 30-minute assessment before the trailer leaves the yard.

• Assessment to live monitoring: 24–72 hours
• Coverage per unit: 1.5–2 acres, 360° with LPR at entry
• Power: solar with 5–7 days no-sun autonomy, no site power required
• Escalation: verified talkdown, then HPD / Harris County Sheriff dispatch
• Service area: Houston, Sugar Land, The Woodlands, Pasadena, Baytown, Conroe, Katy, Galveston, League City, Pearland

Houston contract guards run roughly $28–$42 per hour loaded, so a single unarmed guard on a 12-hour night shift costs about $10,000–$15,000 per month — for one set of eyes that can only be in one place, takes breaks, and turns over often. A monitored Guardtress trailer covers the same perimeter continuously at a fraction of that, and the spend moves from a headcount line to a predictable OPEX line you can hold to the schedule.

The math usually turns on two numbers: what a single loss event costs you in materials plus schedule slip, and whether your carrier offers any credit for a written 24/7 monitoring plan — a question worth asking your broker directly. Full site-by-site pricing is in our construction site security cost guide, and the head-to-head breakdown is at Guardtress vs. security guards.

• Houston guard rate: $28–$42/hour loaded
• One 12-hour guard shift: $10,000–$15,000/month
• Monitored trailer: fixed monthly OPEX, no overtime or turnover
• Builder's risk documentation: written monitoring plan formatted for broker review
