Site Details
Contractor name and contact details: Skanska Construction Company, Johan Karlstorm (CEO), Hans Biork (Chairman)
Project name and site address: Gherkin 30 St Marry Axe at St Mary Axe, London, EC3 United Kingdom
Site manager name and contact details: [please fill]
Transfer of Information from Client / Contractor to Relevant Sub-Contractor
The individual responsible for the craneage’s provision should be agreed
The contractor should concern the hazards including the airspace, power cables, railway lines, and others and the information should be passed to the floor sub-contractor.
The received structure of the project should be confirmed before executing the project from the perspective of structural stability.
Proper and effective safety equipment’s should be available at the site ensuring maximum security to the individuals and staffs working at the project. Structural engineer should provide the approval.
Attendances
Before the execution of the operational activities at the site, the contractor or client will need to execute the following:
Hard Standing for the Crane, and hard access roads will be need to well maintained and provided for the effective transport facilities. There should be enough availability of the space for off – loading or stacking area considering a consolidation of a 12m x 8m area, capability of holding the outrigger loads, and level hard standing as described in the lifting plan.
Availability and maintenance-working area’s perimeter scaffolding including the guardrails, handrails, staging and platform required for the safety access and preventing the activities from falling back.
Flooring sub – contractor should be provided with the welfare facilities in manner to make them comfortable at the sites.
There should be an effective agreement on the provisions related to the precautions against passive fall protective measures. This can be accomplished in an effective and efficient manner through working platforms, safety nets, staging, air bags, crash decks, and staff landing system including air bags.
Work Activity
Pre start Checks: The area including the lifting and crane requirement, structural stability, proximity hazards, work at height, ground conditions, and welfare facilities.
Transfer of Information from Client / Contractor to Relevant Sub-Contractor
Contract Description: Total number of visits to the project will be calculated considering the site visiting by the managers twice a day
Work’s Sequence and erection method: Units will be fixed as per the designed model; fall protection, pole and zip establishment, and ladder will be used for reaching at higher places.
Structural Stability
“Load bearing masonry walls” should be well cured and they should be ready for receiving the concrete units. The block work or external brick will be having levelled with or not more than 225 mm.
Personnel
Backsmman or Slinger erectors, Foreman, Third parties or site operators, training, and appointed person are the personnel involved in the project.
Control Measures, and Health and Safety Management
Site rules as per the safety factors of the employees, better and reliable equipment, access to work area, components’ positioning, working at heights are the considerable factors for the construction site.
Before the enforcement of this method statement, all the individuals and heads involved in the project should be approved on it and if not, the notification should be provided earlier.
Communication agreement will be considered after getting the initials from the key stakeholders.
