Security Services Scope of Work
Describe your site, posts, hours, and duties clearly enough that every security company prices the same service.

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.

What becomes enforceable
Signed before service starts
| Document | Purpose | Who uses it | When it is written |
|---|---|---|---|
| Scope of work | Defines what the provider must deliver, so bidders can price it | Buyer, bidders, procurement | Before requesting proposals |
| Post orders | Turns the scope into step-by-step instructions for each post and shift | Officers and supervisors on site | After selecting the provider, before the first shift |
| Contract | Makes the scope, post orders, pricing, and terms enforceable | Buyer, provider, legal counsel | Before 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.
What a security services scope of work should include
| Section | What to write | Example |
|---|---|---|
| Site description | Address, property type, buildings, fence line, entrances, parking, and operating hours | A 12-acre distribution center with two truck gates and a staff lot |
| Objectives and risks | What the service must protect against, in plain language | Trailer theft, unauthorized entry after hours, and cargo tampering |
| Posts and coverage | Each post, its location, and the days and hours it is staffed | Main gate, 24 hours a day, 7 days a week |
| Duties per post | The specific tasks each post performs | Check driver credentials against the daily delivery list |
| Patrols | Routes, frequency, hours, and whether patrols are on foot or by vehicle | Exterior patrol every two hours from 10 p.m. to 6 a.m. |
| Staffing requirements | Armed or unarmed, required state licensing, and site-specific training | Unarmed officers with forklift-zone safety orientation |
| Supervision | Who supervises, how often supervisors visit, and after-hours contact | Supervisor site visit at least once per shift |
| Reports and records | Report types, fields, delivery time, and retention | Daily activity report emailed by 7 a.m. |
| Communication and escalation | Who to call, in what order, and for which situations | Site manager first, then the facilities director |
| Emergency procedures | Fire, medical, alarm, and severe-weather responses the officer must follow | Follow the site evacuation plan and call 911 first |
| Equipment | What the provider supplies and what the site supplies | Provider supplies radios; site supplies gate keys |
| Changes | How posts, hours, or duties are changed and approved | Written change request approved by the site manager |
The examples show the level of detail bidders need. Replace them with your own site's facts.
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.
| Vague | Specific |
|---|---|
| Patrol the property | Complete 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 visitors | Check photo ID, confirm the host by phone, issue a visitor badge, and log the time in and out |
| Report problems | Report 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 gate | Verify 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.
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.
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.
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.
Scope mistakes that make quotes hard to compare
- Sending different information to different bidders.
- Describing hours as "nights" or "weekends" without exact start and end times.
- Leaving out holidays, special events, or seasonal peaks.
- Asking for "armed or unarmed" without deciding which the site needs.
- Omitting reporting requirements, then discovering that each provider reports differently.
- Forgetting to describe how the scope will change as the site changes.
If you are still deciding on staffing, our armed vs. unarmed guide can help you choose before you write the scope.
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.
Confirm the provider and the terms
This website does not employ guards. Any agreement is between you and the company you select. Confirm qualifications, staffing, insurance, and terms directly; see our referral disclosure.
Scope of work questions
What is a security services scope of work?
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.
What is the difference between a scope of work and post orders?
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.
How detailed should a security scope of work be?
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.
How many officers does a 24/7 post require?
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.
Should the scope of work be part of the contract?
Yes. Attach the final scope as an exhibit so the agreed duties and records become contract obligations.
How often should the scope of work be updated?
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.
