Response Playbook: What Chilliwack and Fraser Valley Contractors Should Do in the First Hours After a Construction Site Break-In

A construction site break-in can disrupt more than one night of work.

For contractors, builders, developers, site supervisors, project managers, and property owners, the problem is often not only the stolen tools, copper, fuel, materials, or equipment. The bigger issue is what happens next.

Who confirms the site is safe?

Who calls police?

Who documents the damage?

Who notifies the project owner, insurer, and site supervisor?

Who changes gate codes, locks, fobs, or keyholder instructions?

Who checks whether the same access weakness is still open for the next night?

This response playbook is written for construction sites, fenced compounds, equipment yards, trailers, storage containers, commercial build-outs, and active job sites across Chilliwack, Abbotsford, Hope, Langley, and the Fraser Valley.

It is not a police procedure manual, legal advice, insurance advice, or emergency response guide. If a break-in is active, someone may still be on site, or there is any immediate safety concern, stay back and call 911. For incidents discovered after the fact, follow the proper police reporting process for your area and your company's internal procedures.

Zentra Protection provides Construction Security, Mobile Patrol, Security Guards, Alarm Response, access-control support, and documented site reporting for businesses, contractors, and properties across the Fraser Valley.

Quick Answer

If you discover a construction site break-in, do not rush straight into cleanup.

First, confirm there is no active threat. If an intruder may still be present, stay away and call 911. If the break-in is discovered after the fact and there is no immediate danger, follow the local non-emergency or online reporting process.

Before moving tools, equipment, locks, containers, or materials, document what you can safely observe. Take photos of entry points, cut fencing, forced trailer doors, damaged locks, open containers, missing materials, and disturbed areas. Notify the project manager, owner, site supervisor, insurer or broker where required, and any security provider involved.

Once police and internal contacts have been notified, re-secure the site. That may include repairing fencing, replacing locks, changing codes, updating keyholder lists, reviewing camera footage, adjusting patrol frequency, or arranging temporary guard coverage for the next night.

The goal is simple: protect people first, preserve useful information, document the loss, re-secure the site, and reduce the chance that the same access gap stays open.

Why This Topic Matters for Fraser Valley Construction Sites

Construction sites are active, changing environments.

A commercial building site in Chilliwack may have trailers, fuel, copper, tools, temporary power, fencing, gate chains, contractor vehicles, equipment, ladders, materials, and multiple subcontractors coming and going. A residential development in Abbotsford may have several open lots, multiple lockboxes, temporary storage areas, and access points that change from week to week. A Hope-area project may have a smaller crew but more remote access concerns. A Langley yard may have higher material volume, more equipment movement, and more overnight exposure.

That changing layout is one reason construction break-ins can be difficult to manage after the fact. The site may look different every day. A gate that was locked on Friday may be opened for deliveries on Monday. A trailer may be moved. A lockbox may be shared by several trades. A camera may cover one side of the yard but not the rear fence. Temporary lighting may not cover the area where tools or copper are stored.

Public local reporting has also shown that business and construction-related property incidents are not only theoretical. Recent Chilliwack-area reporting included storage theft, a job-site trailer break-in, and copper wire theft. Abbotsford Police also reported significant business break-and-enter activity in the first part of 2026. For contractors, the practical lesson is not to panic. It is to have a clear response plan before the next morning becomes disorganized.

A good post-break-in response helps answer four questions:

1. Is the site safe to enter?

2. What happened and what appears to be missing?

3. Who needs to be notified?

4. What security change is needed before the next shift or the next night?

Construction Break-In Response Is Different From Theft Prevention

Most construction security advice focuses on prevention.

Prevention matters. Fencing, lighting, cameras, locked trailers, controlled access, security guards, and mobile patrol all help reduce exposure. But once a break-in has already happened, the priority changes.

At that point, the site needs a response process.

A strong response process helps the contractor:

• avoid putting staff in unsafe situations
• avoid disturbing areas that police may need to review
• record visible damage before cleanup begins
• create a clearer loss list
• notify the right internal contacts
• support insurance documentation
• identify whether locks, codes, or fobs were exposed
• re-secure the property before the next vulnerable period
• decide whether short-term security coverage is needed
• hand the site back to crews without confusion

This is where many construction sites struggle.

A supervisor may arrive early and see a trailer door forced open. A subcontractor may notice missing tools. A gate chain may be cut. Someone may start moving items to "clean up" before photos are taken. A worker may walk through the trailer before police or management has reviewed the scene. A project manager may be notified late. The insurer may ask for details that were not recorded. Security may be called only after the next night's risk is already obvious.

A response playbook prevents that confusion.

Step 1: Confirm Whether This Is an Emergency

The first question is not "what was stolen?"

The first question is:

Is anyone still on site, or is there an immediate safety risk?

If the break-in is in progress, a person may still be on site, someone is seen inside a trailer, a suspicious vehicle is active on the property, or there is any immediate threat, stay back and call 911.

Do not confront anyone. Do not enter a trailer, container, building, or fenced yard if you believe someone may still be there. Do not attempt to search the site yourself.

If the break-in was discovered after the fact and there is no immediate danger, follow the proper non-emergency or online reporting process for the local police agency.

For Chilliwack-area sites, review Chilliwack RCMP reporting guidance. For Abbotsford sites, follow Abbotsford Police Department reporting options. For Langley, Hope, and other Fraser Valley locations, use the appropriate local police or RCMP detachment guidance.

The basic distinction is:

Situation | Likely Action

Break-in appears active or intruder may still be present | Stay back and call 911

Worker sees someone inside a trailer or fenced area | Do not approach; call 911

Site was broken into overnight and nobody is present now | Use local non-emergency or online reporting process

Tools or copper are missing but no immediate danger exists | Document, report, notify internal contacts

Site has dangerous damage, exposed wiring, unstable access, or fire risk | Keep workers away and escalate through the proper emergency/site-safety process

When in doubt, choose safety first.

Step 2: Do Not Disturb the Scene Too Early

After a break-in, it is natural to want to fix the problem immediately.

A supervisor may want to shut the trailer door, move tools back into place, replace a lock, pull vehicles through the gate, or clean up debris. That may be necessary eventually, but it should not happen before the right observations are made.

If police guidance applies, follow it. If it is safe and permitted to observe from outside, record what you can without touching or moving items.

Avoid:

• walking through disturbed areas unnecessarily
• touching damaged doors, locks, handles, or windows
• moving tools, materials, or containers before photos are taken
• cutting away damaged fencing before the entry point is documented
• deleting or overwriting camera footage
• allowing multiple workers to enter the affected trailer or area
• letting subcontractors remove items before a loss list is started

This does not mean the site must remain open or unsafe. It means the first few minutes should be controlled. Document first, then re-secure properly.

Step 3: Identify the Entry Point

Most post-incident decisions depend on how the site was accessed.

Look for the most likely entry point:

• cut fence
• forced gate
• broken gate chain
• damaged padlock
• opened lockbox
• forced trailer door
• opened storage container
• damaged window
• damaged door frame
• vehicle tracks near the gate
• ladder or material moved near a fence
• missing camera
• damaged camera
• open service door
• unlocked access point
• compromised keypad, fob, or access code

The entry point tells you what needs to change before the next night.

If the fence was cut, patrol frequency may need to increase until it is repaired. If a gate chain was cut, a stronger lockup process may be needed. If keys or fobs were taken, access control needs immediate review. If a trailer was forced open, storage and tool control may need to change. If the same area has repeated activity, a temporary guard or scheduled mobile patrol may be appropriate.

Step 4: Take Photos Before Cleanup

Photos are not only for insurance.

They help the project team understand what changed, how the site was accessed, and what needs to be fixed.

Take clear photos where safe and permitted. Do not place yourself or workers at risk. Do not interfere with police instructions.

Useful photos may include:

• overall site entrance
• damaged gate
• damaged fence
• cut chain or lock
• forced trailer door
• damaged container
• broken window or door frame
• disturbed storage area
• missing material area
• tire tracks where relevant
• damaged cameras or lighting
• open lockbox
• affected tool storage
• exposed copper or wire area
• temporary repair made after the incident
• final re-secured condition

Try to take photos in three levels:

1. Wide view - shows the general area.

2. Medium view - shows the affected access point.

3. Close view - shows the specific damage.

Do not rely on one close-up photo of a broken lock. A project manager, insurer, or site owner may need to understand where that lock was located and what area it protected.

Step 5: Start a Simple Incident Timeline

A construction site break-in report should have a timeline.

It does not need to be complicated. It just needs to answer the basic questions clearly.

Record:

• date of discovery
• time discovered
• who discovered it
• who was first notified
• when police were contacted
• police file number, if provided
• when the project manager was notified
• when the owner or client was notified
• when the insurer or broker was contacted, if applicable
• when security was contacted, if applicable
• when the site was re-secured
• what temporary measures were put in place

A simple timeline might look like this:

Time | Action

6:15 AM | Site supervisor arrived and found rear gate chain cut

6:20 AM | Supervisor remained outside affected area and called project manager

6:35 AM | Photos taken of gate, trailer door, and affected storage area

6:50 AM | Police non-emergency report started

7:10 AM | Owner and insurer notified

7:35 AM | Missing tools list started

8:15 AM | Gate temporarily re-secured

9:00 AM | Lock change and patrol review requested

This type of timeline helps keep the response organized.

Step 6: Build a Loss and Damage List

A loss list should be specific.

Avoid vague entries like:

• "tools stolen"
• "copper missing"
• "trailer damaged"
• "site broken into"

Better entries include:

• Milwaukee impact driver, serial number if known
• copper wire spool, approximate length and value
• generator, make/model/serial number
• compressor, make/model
• locked tool chest, forced open
• padlock cut at east gate
• trailer door frame damaged
• storage container latch damaged
• camera cable cut
• lockbox missing
• fuel container missing
• temporary light damaged

For each missing or damaged item, record:

Use this simplified format to record missing tools, damaged access points, and visible site damage after a construction site break-in.

Category | Item / Damage | Quantity | Notes

Tool | Cordless impact driver | 2 | Taken from trailer. Add serial numbers if known. Photo: Yes / No. Approx. value: $____

Material | Copper wire | 1 spool | Stored near electrical area. Photo: Yes / No. Approx. value: $____

Access Point | Gate chain and lock | 1 | East gate cut. Photo: Yes / No. Approx. value: $____

Trailer Damage | Door frame damage | 1 | Forced entry. Photo: Yes / No. Approx. value: $____

This list can support police reporting, insurer communication, internal project records, and future security planning.

Step 7: Notify the Right People in the Right Order

A construction break-in can involve several stakeholders.

Do not assume everyone knows.

The notification order may vary depending on the site, but a practical order is:

1. Emergency services, if there is immediate danger

2. Police non-emergency or online reporting, if discovered after the fact

3. Project manager or site supervisor

4. Property owner, developer, or client

5. General contractor or prime contractor

6. Affected subcontractors

7. Insurer or broker, where required

8. Equipment rental company, if rented equipment is involved

9. Security provider, if the site has patrols, guards, or alarm response

10. Camera/alarm/access-control vendor, if systems were damaged or bypassed

For active construction sites, the prime contractor or site supervisor may also need to review whether the incident affects worker safety, access, site hazards, or the next shift's work plan.

If stolen keys, fobs, keypad codes, lockbox codes, or gate combinations may have been exposed, treat that as urgent. Access credentials can create ongoing vulnerability even after the visible damage is repaired.

Step 8: Review Keys, Codes, Fobs, and Lockboxes

A break-in is not only about what was taken.

It is also about what access may now be compromised.

Ask:

• Were any keys stored in the trailer?
• Was a lockbox opened or removed?
• Were gate keys or building keys taken?
• Did any subcontractor keys go missing?
• Was a keypad code shared too widely?
• Were access fobs stored in a vehicle or trailer?
• Was a master key exposed?
• Are there old codes still active?
• Do temporary workers or former contractors still have access?
• Was the site access list updated after recent trade changes?

If keys, codes, or fobs may be compromised, do not wait.

Possible actions include:

• changing gate locks
• changing trailer locks
• changing lockbox codes
• changing keypad codes
• disabling lost fobs
• reissuing keys only to approved contacts
• updating the access list
• removing former contractors from access
• confirming who is authorized after hours
• updating alarm callout instructions

Access-control gaps are one of the easiest ways for a site to remain vulnerable after the initial break-in.

Step 9: Re-Secure the Site Before the Next Vulnerable Period

The site should be re-secured before the next night, weekend, holiday closure, or low-staff period.

A temporary repair may be necessary before a permanent fix is completed.

Common re-securing steps include:

• repairing cut fencing
• reinforcing the affected gate
• replacing damaged chains and locks
• moving high-value tools off site
• relocating copper or materials into secured storage
• improving lighting near the entry point
• adjusting camera angles
• confirming cameras are recording
• updating alarm contacts
• changing access codes
• checking all trailers and containers
• adding temporary signage where appropriate
• increasing mobile patrol frequency
• placing a guard on site temporarily
• documenting the final re-secured condition

Do not assume one repaired lock solves the issue. If the break-in exposed a larger routine problem, such as shared codes, weak gate control, or poor weekend checks, the site may need a broader adjustment.

Step 10: Decide Whether Security Coverage Needs to Change

After a break-in, the site may need short-term or ongoing security changes.

The right option depends on what happened, what remains exposed, and how quickly the site can be secured.

For example:

• a single cut fence may require temporary repair and added patrol checks
• a forced trailer with missing tools may require overnight patrol or guard coverage
• stolen keys may require immediate lock/code/fob changes
• repeated trespassing may require scheduled mobile patrol or static guard coverage
• an alarm event may require updated alarm response procedures
• missing copper or materials may require better storage and access control

Zentra's Construction Security service can support active sites that need guard coverage, access observation, gate checks, patrol reporting, and coordination with site contacts.

Zentra's Mobile Patrol service may fit sites that need scheduled exterior checks, lock-up verification, perimeter visibility, and after-hours reporting without a full-time guard.

Zentra's Alarm Response service may support sites where alarms are the main trigger and keyholder attendance is unreliable or delayed.

Zentra's Security Guards service may be useful when a site needs a visible on-site presence, contractor access support, temporary overnight coverage, or repeated incident control.

Buyer Decision Table: What Security Step Fits the Situation?

Site Situation | Practical Next Step | Security Option to Consider

Fence cut but no confirmed entry | Photograph, repair, document, and monitor | Mobile patrol until permanent repair is complete

Gate chain or padlock cut | Replace lock, review gate routine, document entry point | Mobile patrol or temporary guard if access remains weak

Trailer forced open and tools missing | Police report, photo log, loss list, insurer notice | Temporary guard coverage or increased patrol

Copper, fuel, or material missing | Document material location, review storage, restrict access | Construction security and mobile patrol

Keys, fobs, or codes may be exposed | Change locks/codes/fobs immediately | Access-control support and guard/patrol update

Camera or alarm system damaged | Preserve footage, repair system, document outage | Guard or patrol until systems are restored

Repeated after-hours trespassing | Review site layout and incident pattern | Scheduled mobile patrol or on-site guard

Site will be closed for a weekend or holiday | Confirm lock-up, contacts, and patrol plan | Mobile patrol and lock-up checks

Active person may still be on site | Stay back and call 911 | Police response first; security only after safe/approved

This table is not a replacement for police, insurance, or site-safety instructions. It is a planning tool to help contractors decide what kind of site support may fit the situation.

Reporting & Documentation

A professional post-incident response should leave a clear record.

Good documentation helps the project team, owner, insurer, and security provider understand what happened and what changed.

A construction site break-in report may include:

• site name and address
• date and time discovered
• who discovered the incident
• police file number, if available
• weather or visibility conditions, if relevant
• areas affected
• suspected entry point
• visible damage
• missing tools, materials, or equipment
• photos taken
• camera footage sources
• workers or subcontractors notified
• owner/client notified
• insurer or broker notified
• temporary repair completed
• lock/code/fob changes completed
• security changes requested
• next-shift handoff notes
• follow-up recommendations

Avoid vague report language such as:

• "everything stolen"
• "site got hit"
• "gate broken"
• "all good now"
• "fixed"
• "checked"

Use clear operational notes:

• "East gate chain cut; photo taken before replacement."
• "Trailer 2 door frame damaged; supervisor notified."
• "Copper storage area checked; one spool missing based on site inventory."
• "Camera on northwest fence not recording; vendor notified."
• "Temporary lock installed at 10:15 AM."
• "Mobile patrol requested for 20:00, 00:00, and 04:00 checks until fence repair is complete."

The more specific the documentation, the easier it is to understand the event later.

Zentra Field Note: The First Hour Sets the Tone

After a construction site break-in, the first hour can determine whether the response stays organized or becomes confusing.

A common situation is a supervisor arriving early and finding a trailer door forced open or a gate chain cut. The instinct is to fix the door, move tools, call a few trades, and get the site back to work. That may feel productive, but it can create problems if photos, loss notes, police reporting, and access-control review are skipped.

A better first hour is calm and structured:

• confirm the site is safe
• do not enter if someone may still be present
• avoid disturbing the affected area
• take photos where safe
• notify the project lead
• contact police through the correct channel
• start a loss list
• identify whether keys, codes, or fobs are affected
• re-secure the site
• decide whether the next night needs patrol or guard coverage

The goal is not to turn the contractor into an investigator.

The goal is to make sure the site is handled professionally, documented clearly, and re-secured before the next vulnerable period.

What to Photograph After a Construction Site Break-In

Photos should tell the story clearly.

A useful photo set may include:

1. The Site Entrance

Take a wide photo of the main gate, driveway, or access point. This helps show where the affected area is located.

2. The Entry Point

Photograph the cut fence, damaged gate, broken lock, forced door, or affected trailer/container.

3. The Damage

Take clear photos of door frames, hinges, locks, latch areas, camera damage, fence openings, or broken windows.

4. The Storage Area

Show where tools, copper, fuel, or materials were stored before they went missing.

5. The Missing Item Area

Take photos of empty shelves, open toolboxes, disturbed containers, or the location where materials were stored.

6. The Re-Secured Condition

After police guidance and site procedures allow it, photograph the temporary repair or final re-secured condition.

This final photo matters because it shows that the site was not left exposed after the incident was discovered.

When Mobile Patrol May Be Enough

Mobile patrol may be a good fit when the site does not need a full-time guard but still needs after-hours visibility and checks.

Mobile patrol may fit when:

• the site is mostly secured but has a temporary weak point
• the break-in happened after hours and the site needs extra checks
• the fence or gate repair is pending
• the site is closed over a weekend
• the contractor wants lock-up confirmation
• camera or alarm coverage needs physical support
• materials remain on site but can be checked at intervals
• there is no active threat and no need for continuous guard presence

Mobile patrol can support:

• gate checks
• fence line checks
• trailer/container exterior checks
• lock-up verification
• visible patrol presence
• photos where appropriate
• incident notes
• escalation to site contacts

It is not the same as a full-time guard. It is best when the site needs scheduled checks rather than continuous attendance.

When Temporary Guard Coverage May Be Needed

A temporary guard may be more appropriate when the site needs continuous or dedicated presence.

Temporary guard coverage may be considered when:

• a trailer or container cannot be fully re-secured
• valuable tools or materials remain exposed
• keys, fobs, or codes may be compromised
• repeated incidents have happened
• the site has no working alarm or camera coverage
• a fence or gate repair will take time
• contractors need controlled access the next morning
• the site owner or insurer requests stronger visible coverage
• the project has high-value materials or equipment on site
• the incident creates concern about the next night or weekend

A guard can support:

• access-point observation
• contractor entry support
• perimeter checks
• gate control
• incident reporting
• site contact escalation
• visible deterrence
• documentation of site conditions

A guard does not replace police, investigate the theft, or guarantee that another incident cannot happen. The role is to provide professional site presence, observation, communication, and reporting.

Alarm Response After a Construction Site Break-In

Some construction sites have alarms in trailers, offices, storage containers, temporary buildings, or fenced compounds.

After a break-in, the alarm process should be reviewed.

Ask:

• Did the alarm activate?
• Who received the call?
• Was the keyholder available?
• Did anyone attend the site?
• How long did it take?
• Was the alarm ignored because of previous false alarms?
• Was the alarm contact list current?
• Was the alarm zone clear?
• Was the alarm disabled or damaged?
• Did cameras capture anything useful?
• Was the monitoring company updated after the incident?

If alarm calls are going to the wrong person or the keyholder cannot attend after hours, the site may need a more structured Alarm Response plan.

A good alarm response process should identify:

• who receives the alarm
• who can attend
• who has keys or access
• who gets notified after attendance
• what gets documented
• when police are contacted
• what happens if the site cannot be secured

Construction Site Handoff After a Break-In

The next shift matters.

A break-in discovered at 6:00 AM can affect workers arriving at 7:00 AM. If the site is not managed properly, workers may enter damaged areas, move items, use unsafe access points, or continue work without knowing what happened.

A good handoff should include:

• affected area
• whether police have been contacted
• whether the area can be entered
• what items appear missing
• what damage is present
• what repairs are pending
• what locks/codes/fobs have changed
• whether certain areas are restricted
• whether security coverage has changed
• who is the point of contact for follow-up

The goal is not to delay the whole project unnecessarily.

The goal is to restart safely, clearly, and with fewer assumptions.

Final Thoughts

A construction site break-in can create pressure quickly.

Crews may be arriving. Tools may be missing. A trailer may be open. The owner may be asking questions. The insurer may need documentation. The project manager may need the site operating again. The next night may still be exposed.

The best response is calm and structured.

Confirm safety first. Call 911 if the incident is active or there is immediate danger. If the incident is discovered after the fact, report it through the correct local process. Avoid disturbing possible evidence too early. Photograph what is visible and safe to document. Notify the right contacts. Start a loss list. Review keys, fobs, codes, and lockboxes. Re-secure the site before the next vulnerable period.

Then decide whether the site needs additional support.

For some sites, mobile patrol may be enough. For others, temporary guard coverage, access monitoring, alarm response, or a stronger construction security plan may be needed.

If your construction site, equipment yard, trailer, or fenced compound needs practical security support after a break-in or attempted entry, Zentra Protection can help with site checks, temporary guard coverage, mobile patrol, alarm response support, access observation, and documented reporting.

Frequently Asked Questions

What should I do first if I find a construction site trailer forced open?

First, confirm whether there is any immediate danger. If someone may still be on site or the break-in appears active, stay back and call 911. If the incident was discovered after the fact, avoid disturbing the area, notify the project lead, document visible damage, and follow the proper local police reporting process.

When is a construction site break-in a 911 call?

Call 911 if the break-in is active, someone may still be on site, a worker is at risk, there is a fire or immediate hazard, or there is any urgent safety concern. If the incident happened overnight and no immediate danger exists, use the proper non-emergency or online reporting process for the local police agency.

Should we move tools or clean up before police are contacted?

Avoid moving items too early unless safety requires it. Take photos where safe, limit access to the affected area, and follow police guidance. Moving tools, locks, containers, or damaged materials too soon can make the incident harder to document.

What should be photographed after a construction site break-in?

Photograph the site entrance, damaged gate or fence, forced trailer or container, broken locks, missing material areas, tool storage areas, damaged cameras or lighting, and the final re-secured condition. Use wide, medium, and close photos so the project team can understand the full situation.

Who should be notified after a construction site break-in?

Notify police through the appropriate channel, then notify the project manager, site supervisor, property owner or developer, affected subcontractors, insurer or broker where required, security provider, and alarm/camera vendor if systems were involved.

When should locks, codes, fobs, or gate chains be changed?

Change them immediately if keys, lockboxes, access codes, fobs, or gate controls may have been exposed. A break-in can create ongoing vulnerability if old access credentials remain active.

When is mobile patrol enough after a construction site break-in?

Mobile patrol may be enough when the site can be re-secured but needs scheduled exterior checks, gate checks, lock-up verification, and after-hours visibility. It is not the same as continuous guard coverage.

When should a temporary guard be placed on site?

A temporary guard may be appropriate when the site cannot be fully re-secured, high-value tools or materials remain exposed, keys or codes may be compromised, camera or alarm systems are down, or repeated activity has occurred.

Does Zentra investigate construction site theft?

No. Zentra Protection does not conduct police investigations or recover stolen property. Zentra can support site security, access observation, mobile patrol, temporary guard coverage, alarm response support, incident notes, and documented reporting where safe and permitted.

Can a security report help with insurance?

A security report may help document observations, timelines, site conditions, photos, and re-securing actions. It does not guarantee claim approval. Always follow your insurer or broker's instructions for proof of loss, documentation, and claims handling.

What should be included in a construction security incident report?

A useful report should include the date, time discovered, who discovered it, affected areas, entry point, visible damage, missing items, photos, police file number if provided, notifications made, temporary repairs, access changes, and next-shift handoff notes.

What if copper, fuel, tools, or materials were stolen overnight?

Start a loss list with item descriptions, quantities, serial numbers where available, approximate values, storage location, and photos. Report the incident through the proper police process, notify the project lead and insurer where required, and review whether storage, access control, patrol, or guard coverage needs to change.

How do we hand the site back to crews after a break-in?

Give crews clear instructions before work resumes. Identify affected areas, what has been reported, what is still restricted, what locks or codes changed, what is missing or damaged, and who is responsible for follow-up.
