Method statements
The CDM regulations require the contractor to prepare method statements for
approval by the clients representatives prior to works being undertaken. Likewise
subcontractors are required to submit method statements prior to them undertak-
ing operations on site.
Method statements are directly linked to “safe methods of working” and hence to
risk assessments. At the subcontractor's induction meeting on site, emphasis is
placed on the fact that operations cannot proceed without familiarity with both the
task method statement and the associated risk assessments.
No standard format for presenting method statements has yet been developed.
They may be presented in written form or as a tabular presentation. Method state-
ments may be part of the tendering process as many tenders are won on a construc-
tion method approach. When considering alternative approaches at the “value
engineering” stage of a design and build project a construction method approach is
essential.
The areas considered during the preparation of a method statement for concret-
ing operations and associated risk assessments are shown. Extracts from site spe-
cific method statements are outlined for concrete laying and finishing to the car
park area.
A risk assessment format is shown for fire hazards likely to be encountered.
Method statement for suspended floor to steel framed building
(car park). 150mm Insitu suspended floor to steel framed
building (car park)
Description of Task
The method statement and risk assessment covers the placing of 150 mm insitu con-
crete to a metal deck floor. The work is to be undertaken by a specialist floor laying
contractor as part of a package contract on a Design and Build project. The method
statement and risk assessment have been produced for the contractor by a safety
consultant.
Sequence of Work
A plan of the first floor car park is shown. This indicates that the suspended floor is to
be poured in six 18m wide bays across the width of the building. The access ramp to
the first floor is to be poured separately (bay pour 7). The quantity of concrete per
pour approximates some 122 cm. The pouring sequence is based on pouring one
bay per day from bay 1 to 7. The stop end between bays is to be removed prior to the
next pour.
