Welcome to the MCHW
There has been a change in name for the button previously called ‘Archive’ in the top right hand corner of the website. The search functionality remains the same but the term older versions is a better representation that some older versions of standards are used on current schemes and projects.
The Manual of Contract Documents for Highway Works (MCHW) is our standard suite of specification documents which are included within a construction contract and the Contractor is required to comply with its contents.
