Scope gap checker

SUBR's free scope gap checker reads a scope of works and lists what it leaves unsaid from a list of common items: twelve things every scope should settle, such as access, waste, programme and making good, and the items most often missed for seven trades. It works the same whether the scope goes to a subcontractor or to your own team.

Free, with no sign-up. Everything is worked out in your browser: nothing you type is sent to us. Written rules in your browser, not AI. SUBR's AI does this reading for real. Nothing you paste is sent anywhere. A job you carry to another tool is kept in this browser tab only, until the tab is closed.

Check a scope for gaps

Pick the trade and paste the scope. It checks for the common items that most often get missed, whether the work goes to a subcontractor or to your own team. The lists are common items, not an official standard.

Package Manager This scope leaves 13 common items unsaid, including steel schedule or section factors and coating thickness (DFT) to be achieved for this trade. Whether a subcontractor or your own team does the work, anything unsaid becomes an argument or an extra later. Add a line for each, even if it says "by others".

Why gaps cost money

Anything a scope leaves unsaid is settled later, on site, when it costs most. With a subcontractor it comes back as a claim for an extra. With your own team it comes back as a crew waiting for access, power or a drawing, paid either way.

How it reads

Written rules in your browser, not AI. SUBR's AI does this reading for real. It looks in the scope for the words each item is usually written in. The lists are common items, not an official standard, and trade reviewers keep them up to date. An item counts as covered once the scope mentions it, so a tick means the scope says something about it, not that what it says is right.

Questions

What should a scope of works include?

What the work is, where, to what standard and by when, and who provides everything around it: access, attendance, welfare, waste removal, protection, power, water and storage, drawings with their revision numbers, making good, handover documents, and RAMS and permits.

Who pays for something a scope does not mention?

Usually that becomes the argument. An item nobody priced comes back as a claim for an extra or as work done for free. Write a line for each item, even if the line says it is by others.

Does a scope for my own team need the same detail?

Yes. Your own team will not send you a claim for an extra, but a gap still costs time: a crew waiting for access or power on its first morning is paid either way.

Where the figures come from

Every number this tool works with is one you enter. It uses no outside rate, threshold or date, so there is nothing to look up.

Where SUBR comes in

SUBR is AI job software for UK contractors. One quote becomes scopes, supplier requests and jobs, whether subcontractors or your own teams deliver the work, and your margin stays private. Its AI reads your client quote, your office names each trade's share, and SUBR builds every scope with your costs, margin and client price left off it. Each subcontractor answers on their own link and sees only their own price.
