ConCom (Contractor’s Competency Forum)

The Humber Contractor Competency Forum was formed in 1999 by a group of collaborating clients and supporting contractors to establish and develop high standards of competency for companies and their employees working on the Humber Bank process industry sites.

The ConCom team carries out an audit (usually every 2 years) on contractors who are working on, or clients are intending to use, on their sites using an audit template agreed by the client group. The audit report and data is then made available to all the client members so that the contractor is only audited once, regardless of how many of the clients they currently work for.

ConCom supports contractors in improving theirs systems and competency by promoting and sharing best practice and providing training targeted at areas found to be weak during system or site audits. ConCom is a collaborative and supportive tool promoting continual improvement.
