TASK: Drainage, Excavate, Blinding, Reinforcement, Shuttering and
      Concreting to Beams

LOCATION: Ancillary Buildings

DURATION: 6 weeks


METHOD:

Excavations

The area to be excavated will be clearly marked on the surface. Excavation will be
carried out with a 360 excavator to the correct level with the use of a rotating laser.
The excavated material will be loaded into a dumper taken and tipped away from the
working area. Extra excavation will be taken and filled sand or pipe bedding in the
positions of the drainage.

Blinding Concrete

Levels will be marked in the excavation with the rotating laser for the top of the
blinding concrete. The concrete will be taken directly from the concrete mixer and
placed into the excavation with a 360 excavator. The concrete will be smoothed out
ready to receive the steel.

Steel Reinforcement

The steel reinforcement will be prefabricated as our Method Statement No.003. It will
then be lifted into position with a 360 excavator onto the blinding concrete and any
additional bars to join the beams will be fixed in position. (Attached Method
Statement No. 003).

Shuttering using Corrugated Beam Form

Corrugated Beam form will be placed at the side of the steel reinforcement and
spaced off the steel with the appropriate clips as supplied by Corrugated Beam Form
Limited. (Technical brochure for Beam form Held in site office. The Beam fill will be
backfilled on the outside using 20mm pipe bedding.

Concreting Beams

The concrete will arrive on site premixed in a concrete wagon. The concrete will be
transferred into an excavator bucket from the concrete wagon. The concrete will be
placed in the beams from the excavator bucket. The concrete will be vibrated using a
vibrating poker. The concrete will be levelled and floated with trowels or easy float.
Hessian or a concrete curing agent will be used to cure the concrete.

Drainage

Attached Method Statements Excavation up to 3 Metres deep. Once the beams
have been concreted the drainage will be laid under the beam on Grid Line A and
brought up onto the beam on Grid Line B and fixed in the correct position.

CONTROL:

The works will be carried out by experienced operatives who will be supervised
during the whole of the works. Only experienced- trained operatives will operate the
plant and equipment. All personnel within the work area will wear the appropriate
PPE. Statutory examinations will be carried out on all plant, equipment with records
kept. Only authorised-trained operatives will be permitted to drive any plant vehicles
and mount abrasive wheels on company machines. Once the concreting is complete
the excavation will be fenced off to prevent anyone falling into the excavation.
All excavations will be fenced off if unattended at any time.

GENERAL:

It is our intention to promote a safe working environment and to this end, we would
insist on full co-operation from all contractors and the general public. The works will
be carried out by experienced operatives who will be supervised during the whole of
the works. All operatives will be issued with personal protection equipment. All
operatives will be expected to wear any, and all personal protection equipment
provided. Operatives failing to wear the equipment or take care of themselves or
others will be reported to the office and disciplinary action will be taken. All plant
operators to hold a valid CTA card or CPCS card. Only experienced – trained
operatives will operate the plant and equipment. Statutory examinations will be
carried out on all plant, equipment with records kept, daily and weekly. Only
authorised-trained operatives will be permitted to drive any plant vehicles and mount
abrasive wheels on company machines. No excavations to commence until a permit
to dig has been issued and all services have been located. When reversing wagons
a banksman should be in attendance at all times. All excavation will be fenced off at
all times. Ladders used only for access and egress. Only trained operatives are to
enter a confined space.

RISK ASSESSMENTS:

Excavators.
Open Excavations.
Use of an excavator as a crane.

A)      Excavation work up to 3 metres

        Prior to work commencing, a pre-assessment of the ground conditions will be
        carried out by an engineer, this will involve taking cognizance of the
        immediate environment, any other works being carried out in the area
        adjacent, the likelihood of water ingress etc. This assessment will be
        reviewed as works proceeds and recorded in the excavations inspection
        register.

        The works will be executed by means of 1800 hydraulic wheeled excavators
        or 3600 hydraulic tracked excavators.

        Excavations will either be ‘battered’ back to a slope suitable for the prevailing
        ground conditions or supported by one of the following means:-

        a)     Hydraulic ‘box’ shoring systems.
        b)     Trench sheeting braced by hydraulic waling frames or box frames.

        Whichever is appropriate dependent upon location and ground conditions.

        Backfilling to excavations will be conducted progressively with support
        systems being withdrawn similarily.

        Compaction of backfill will be appropriate plate/drum compaction equipment.

        All machine and plant operators (where appropriate) will carry CITB or
        equivalent qualifications.

        All plant/equipment will carry/or will have on site certification appropriate to
        their usage.




                                                                               MS002/2008

        All excavations are to be isolated from unauthorised personnel (where
        necessary) both during working hours and at night time by an appropriate
        barrier system.




        Trench will be monitored for gas by means of a gas detector at start of
        working day prior to entry and through out the working shift.

        Operative will work within the shoring boxes at all times.

        Sides of trenches to be pulled into sides of box to stop open traps
