This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

A desk study of this derelict (Brownfield) site, situated within the village centre of Willingbury, stated that the grounds had previously been used for industrial and commercial purposes.

There's a high possible risk of contamination within the grounds.

A main on-site investigation involving sampling and analysis is to be done to gain ground conditions for each specified task; this will be undertaken at several successive stages within works.

Ground contamination and soil testing requires the removal of all known contaminants to levels considered safe for human health.


Company resident liaison staff have visited all properties and schools within the surrounding area and kept local residents informed of all times, routes and stages of work, by means of telephone, leaflets and local planned resident meetings.

Existing services

Prior to any works being carried out, the existing services within this site must be found and located, and then consulting the relative statutory authorities to discontinue services as needed. Cables will be located using a CAT scanner, which covers services, gas, water, electricity, telephone, and communications.

Site information

This is to be a NON PARKING SITE for all on site personnel.

Due to limited space and hazards arising from demolition works, parking is restricted to out side area only, local NCP car park.

There will be an allocated space for emergency vehicles, positioned next to the first aid room.

The induction room will be situated by the pedestrian access area in Green Street.

During a site induction all personnel will be made aware of the client's site rules. Accident reporting and site emergency procedures will be shown to all.

Statutory items will be kept in the site office and will consist of an F10; this will be displayed in the site office on day 1 of works. It will be completed by the CDM Coordinator of this project.

Other items included would be a public/products liability insurance form a health and safety policy that will need to be updated daily, a health and safety poster along with all the relevant registers, i.e. induction, sign in book, LOLA 1998, PUWER 1998, COSHH 2002, excavation reports, asbestos reports, and scaffold inspection forms.

Method statements and risk assessments will be submitted for each significant task, this will be read and understood by each appropriate tradesman before any work begins this will also be updated on a daily basis.

Induction process

Induction - this will be given upon first arrival to site (for operatives and visitors).

Site rules - contains relevant health and safety issues.
