The Considerate Constructors Scheme has extended the its Monitors' Checklist to include checks on a site's smoking and drugs policy, and what it does to encourage literacy and numeracy among its workers.
They are among a number of new questions which have been added to the checklist, which sites must address in order to comply with the CCS Code of Considerate Practice.
The scheme, which visits 1,000 sites every month, added the new questions after consultation with its associate members, monitors and directors.
The CCS, which was established in 1999, registered its 40,000th site in December.
* The CCS has reported growing interest in its Company Registration scheme, launched in July last year. The initiative allows construction companies to benchmark their performance, and demonstrate to clients a willingness to aim for standards beyond statutory requirements. Members of the National Federation of Builders, Constructionline, and The Chartered Institute of Building's Chartered Building Scheme receive a 10% discount on membership.
