How we designed an award winning garden – Part 6

CDM, Specification of Works & Schedule of Quantities

This is the final instalment in our series of blogs on the whole garden design process. Here we discuss 3 essential documents which detail the minutiae of the project.

The Construction (Design & Management) Regulations 2015 (CDM 2015) are a set of health and safety regulations brought in in 2015. They outline the client’s responsibility to ensure that their garden can be built, maintained (and deconstructed at the end of its life) in a safe way.

We will produce a Pre-construction Health & Safety Information Pack. This provides specific information on the site risks and hazards, identified by us and the client during the design and early planning phases of the project. It considers how these risks can be identified and controlled. This pack is then passed onto potential contractors during the tendering phase and should be referred to throughout the garden construction process.

The Specification of Works is a very detailed description of the materials and workmanship involved in the garden. It is often a 30 page document which not only helps the contractor to cost and construct the project, but also acts as a contract between the client, designer and contractor, so that everyone knows exactly what is required of them.

The Schedule of Quantities lists quantities of items required for each element of the garden, from paving to the portable toilets required for the contractors! The contractor then uses this the produce a detailed quote for the client.
