Blackwell has a long-term commitment to managing and controlling the health and safety, quality and environmental aspects of its business. The company recognises that its reputation depends upon quality performance and strenuous efforts are made by management to pursue this objective. Our management systems are designed specifically for the company’s operations on site which include earthmoving, civil engineering construction, soil remediation and geotechnical improvement works.

Health and Safety

Blackwell commits itself to implementing the Health and Safety at Work Regulations, in line with the company's BS OHSAS 18001 accreditation. The company is registered with the British Safety Council and has gained fourteen top international safety awards, including one for 2008. The safety system incorporates a detailed policy and procedures outlining all instructions for personnel. Blackwell is in the process of implementing the Incident and Injury Free (IIF) Programme promoting behavioural safety to assist the continuing improvement of our health and safety performance. The company's Safety Leadership Team was formed to co-ordinate, review and champion the IIF process and focus on the integration of the IIF culture across all aspects of the business.
