Contractor Management Software for Construction

Contractor management on construction projects: competence, appointment and site rules

Construction runs on subcontractors, and the law puts the burden of checking them on the people who appoint them. Anyone appointing a contractor has to take reasonable steps to confirm that it has the skills, knowledge, experience and organisational capability for the work, and contractors have their own duty to plan and supervise what they do. On sites with more than one contractor, a coordinator and a written safety and health plan are expected.

Software helps in three places: prequalification before appointment, site admission (induction, current tickets, today's permit), and ongoing monitoring. Decide which of the three you are buying for. Check who reviews those documents, what happens when a card expires mid-project, and whether a site gate can check a worker without a connection.

External participation is also a cost line. Pricing models differ between the listed products (subscriptions paid by contractors, by the hiring client or per worker), so ask for the full cost of adding one more subcontractor to a live project.

Rules that shape this evaluation

• CDM 2015, regulation 8 (Great Britain): a designer or contractor appointed to a project must have the skills, knowledge, experience and, for an organisation, the organisational capability to fulfil the role safely, and those who appoint them must take reasonable steps to satisfy themselves of it.
• CDM 2015, regulation 15: contractors must plan, manage and monitor the work under their control, and must not start until satisfied that the client knows its duties.
• Directive 92/57/EEC, Article 3 (EU): the client or project supervisor appoints safety and health coordinators on any site with more than one contractor and ensures a safety and health plan is drawn up before the site is set up.

Summarised from the linked official texts, read on 25 September 2026. This is buyer context, not legal advice: have the responsible specialists confirm which requirements apply to your sites.

How the operating context changes the buying criteria

Separate three layers that vendors often present as one. Company prequalification (insurance, policies, safety record, certifications) says little about whether the six people arriving on Monday have been inducted for this site, and a site induction says nothing about whether a worker may carry out work at height or operate a particular machine. Ask whether the product holds all three layers, company, worker and task, and links them, so that an approved company, a verified worker and an authorised task can be checked together at the gate or in the supervisor's hands.

Contract chains are deeper than the contract. A main contractor appoints a subcontractor, which engages a labour-only firm or an agency, whose workers may appear under no approved company at all. Ask how the product shows the whole chain, who is recorded as responsible for checking a lower tier, and how it treats a worker who belongs to no approved company. Short engagements add friction: a crew on site for a week will not complete a long onboarding, so ask for the time a small firm needs for its first onboarding, and whether documents it already uploaded for another client can be reused rather than keyed again.

Questions to settle for this combination

1. Who reviews a subcontractor's uploaded documents (you, the vendor or the subcontractor itself), and what does that review establish?
2. Can the site gate or supervisor check a worker's induction and tickets without connectivity, and how old can that data be?
3. When a qualification expires mid-project, does the worker's site access change automatically or only raise an alert?
4. Can each subcontractor see only its own workers and documents, and what does external participation cost per company?
5. Does the tool hold the project-specific induction, or only company-level prequalification?

Further questions for each vendor

• Which tiers of the contract chain can the tool show, and who is recorded as responsible for checking a sub-subcontractor's workers?
• How does the tool treat agency or labour-only workers who belong to no approved company?
• Can site access be tied to the trade activity, such as work at height, excavation or lifting, and not only to a general site induction?
• Can a subcontractor reuse documents it uploaded for another client, and does the reuse show as that contractor's own evidence?
• How is a subcontractor's removal from a project recorded, with the reason, and what happens to its open actions and permits?
• When a firm works on three of your projects, who pays under the quoted model, you or the contractor, and how often?

What an inspector or auditor typically asks to see

• The appointment record: how each contractor's competence was checked before it was appointed, by whom and on what documents.
• The induction record for each worker and a list of who was on site on a given date, which an investigation after an incident will need.
• Risk assessments and method statements for high-risk tasks, with proof that supervisors and operatives reviewed them before starting.
• Evidence that tickets or cards were valid on the day of the task, for example for plant operation or work at height.
• Monitoring records: how the principal contractor checked subcontractors' work, and what was done where it fell short.

Which documented capabilities matter most here

Offline matters less here than on a remote site, because most projects have a cabin with a connection, though a gate or a crane base may not. Weight the category line first, since the listed products differ in whether they serve prequalification, site access or both, then the price line, because the cost of external participation is decisive in this combination. A documented free trial lets you invite one real subcontractor before you sign, which tells you more than any list of features.

Signals in the researched records of the listed products:

• Contractor Management is the primary category in the record of Avetta, SafeContractor and ISNetworld (ISN).
• Matched through a sourced tag or a documented capability rather than the primary category: HammerTech, HSI Donesafe, Quentic, SiteDocs and Workhub.
• Offline use, as classified in the records: a documented offline workflow: HammerTech, HSI Donesafe, Quentic and SiteDocs; a partial offline workflow: Avetta and Workhub. No classification yet for 2 of the 8.
• A published price amount is on record for Avetta, SafeContractor and Workhub; the other 5 need a quote.

Vendor-material signals, not test results; the commercial partner is not counted; no signal means not established.

A demo script for this combination

Ask each vendor to run these steps with synthetic data. They are demo requests, not observed vendor results.

1. Invite a synthetic subcontractor, have it upload two workers' tickets and review one as rejected.
2. Let the certificate of the approved worker expire mid-project and observe what changes at the site gate.
3. Check the worker's status on a phone with no connection and note the age of the cached data.
4. Confirm that the subcontractor sees only its own workers and documents.
