Security Services Scope of Work

Describe your site, posts, hours, and duties clearly enough that every security company prices the same service.

Short answer

One scope, comparable quotes

A security services scope of work tells bidders exactly what you are buying: the site, the posts, the hours, the duties, the records, and the escalation rules. Send the same scope to every provider, and the proposals become comparable. The scope later becomes the basis for the post orders and an exhibit to the contract.

Three documents

Scope of work, post orders, and contract

Buyers often mix these documents together. Each has a different job.

  1. 1

    Scope of work

    What you are buying

    Written before you request bids

  2. 2

    Post orders

    How each post works, shift by shift

    Written before the first shift

  3. 3

    Contract

    What becomes enforceable

    Signed before service starts

DocumentPurposeWho uses itWhen it is written
Scope of workDefines what the provider must deliver, so bidders can price itBuyer, bidders, procurementBefore requesting proposals
Post ordersTurns the scope into step-by-step instructions for each post and shiftOfficers and supervisors on siteAfter selecting the provider, before the first shift
ContractMakes the scope, post orders, pricing, and terms enforceableBuyer, provider, legal counselBefore the service starts

A scope that is too vague produces proposals that cannot be compared. A scope that is too detailed about daily routines belongs in the post orders instead. Aim for a scope that answers what, where, when, and how it will be proven.

The outline

What a security services scope of work should include

SectionWhat to writeExample
Site descriptionAddress, property type, buildings, fence line, entrances, parking, and operating hoursA 12-acre distribution center with two truck gates and a staff lot
Objectives and risksWhat the service must protect against, in plain languageTrailer theft, unauthorized entry after hours, and cargo tampering
Posts and coverageEach post, its location, and the days and hours it is staffedMain gate, 24 hours a day, 7 days a week
Duties per postThe specific tasks each post performsCheck driver credentials against the daily delivery list
PatrolsRoutes, frequency, hours, and whether patrols are on foot or by vehicleExterior patrol every two hours from 10 p.m. to 6 a.m.
Staffing requirementsArmed or unarmed, required state licensing, and site-specific trainingUnarmed officers with forklift-zone safety orientation
SupervisionWho supervises, how often supervisors visit, and after-hours contactSupervisor site visit at least once per shift
Reports and recordsReport types, fields, delivery time, and retentionDaily activity report emailed by 7 a.m.
Communication and escalationWho to call, in what order, and for which situationsSite manager first, then the facilities director
Emergency proceduresFire, medical, alarm, and severe-weather responses the officer must followFollow the site evacuation plan and call 911 first
EquipmentWhat the provider supplies and what the site suppliesProvider supplies radios; site supplies gate keys
ChangesHow posts, hours, or duties are changed and approvedWritten change request approved by the site manager

The examples show the level of detail bidders need. Replace them with your own site's facts.

Writing duties

Write duties that can be checked

Vague duties invite different interpretations and different prices. Write each duty so a supervisor could confirm it was done.

VagueSpecific
Patrol the propertyComplete an exterior patrol of the loading dock, fence line, and parking lot every two hours between 10 p.m. and 6 a.m., and record each round
Monitor visitorsCheck photo ID, confirm the host by phone, issue a visitor badge, and log the time in and out
Report problemsReport an open door, broken fence, or unsecured trailer to the site manager within 15 minutes and include it in the daily report
Provide security at the gateVerify each truck against the delivery list, record the trailer number, and deny entry to unlisted vehicles until the shipping lead approves

The times and intervals in these examples are illustrations. Set the values that fit your site and your risk.

Coverage hours

One post is not one officer

A post staffed 24 hours a day, 7 days a week needs 168 hours of coverage every week. That is roughly four to five full-time officers once days off, vacation, training, and sick time are covered. When you compare proposals, ask how many officers each provider plans to assign to the post and how relief is handled.

State the coverage in hours per post per week. It makes proposals easier to compare and invoices easier to check. For a planning estimate, use the Digital Guard Tour cost calculator; our security guard cost guide explains what drives the bill rate.

Estimate Your Cost

Exclusions

Say what the service does not include

A scope that lists only duties leaves room for assumptions. State what officers are not expected to do, such as handling cash, operating site equipment, or entering areas that require special training. If you need a separate service, such as a fire watch or mobile patrol for another site, scope it separately.

Clear exclusions protect both sides. The provider knows what it is pricing, and you know what you can and cannot ask of the officer on site.

Records

Define the evidence before the service starts

The scope should say which records prove the service was delivered: daily activity reports, incident reports, patrol records, gate logs, and missed-post notices. For each record, name the required fields, the delivery time, who receives it, and how long it is kept.

Records defined in the scope can be written into the contract and reviewed during the term. Our provider accountability guide explains how to review them. Digital Guard Tour is separate patrol-verification software published by Trinity Guard LLC; it is not a security guard company.

Common mistakes

Scope mistakes that make quotes hard to compare

Next steps

From scope to contract

Use the finished scope as the core of your request for proposals, then compare the answers with our questions to ask a security company guide. After you select a provider, turn the scope into post orders for each post. Attach both documents to the agreement, and review the final terms with the security guard contract checklist.

FAQ

Scope of work questions

It is the document that defines what a security provider must deliver at your site: the posts, hours, duties, patrols, records, and escalation rules. Bidders use it to price the service, and it later becomes part of the contract.

The scope defines what must be delivered and is used for pricing. Post orders are the detailed, shift-level instructions officers follow on site. Post orders are written from the scope after a provider is selected.

Detailed enough that every bidder prices the same service: exact posts, hours, duties, patrol frequency, and reporting. Day-to-day routines and site procedures belong in the post orders.

A 24/7 post needs 168 hours of coverage per week, which usually means roughly four to five full-time officers once time off and training are covered. Ask each provider how it plans to staff the post.

Yes. Attach the final scope as an exhibit so the agreed duties and records become contract obligations.

Whenever the site, hours, risks, or duties change, and at least at each contract review. Use a written change process so updates are approved and priced.
