safe pedestrian access / signage and relevant traffic management systems.5. Issue to the operatives a permit to dig with a copy of the relevant service drawings.6. All ACS site operatives & management associated with the project, have the appropriate

CSCS / CPCS training certs.7. All Approved for Construction drawings & Schedules will be available on site.8. Sufficient and suitable welfare facilities will be established on site by the client.9. The works area and agreed fencing lines has been defined and agreed between all parties.

Once the above is in place, site works can proceed as follows:

DRAINAGE SEQUENCE

The site engineer will mark out the position of the drainage run to the latest revision drawing. Proposed manhole location will then be excavated using the 20t Excavator to a depth of

225mm below the existing pipe invert level a per the specification. The excavation will be checked on weekly basis and recorded on an excavation inspection

sheet by a competent person. The excavation will receive a visual inspection at the start of each shift by a competent person.

Manhole excavations will be stabilized using sheet and frame shoring equipment. Temporary works designs will be passed on to the client for approval before work commences.

Access to the excavation will be via a wooden pole ladder fixed to a purpose made ladder platform that is attached to the trench sheets.

A gas monitor will be hung on a rope within the excavation throughout the shift. Readings will be logged on a topman record at 8am, 1030am, 130pm and 4pm.

An escape set will be kept within easy reach in the excavation throughout the shift. All material generated will be left on site and the laydown/ storage area will be confirmed and

agreed with BECGI on site. On completion of the excavation specified concrete will placed to the man hole base, additional

care will be taken to ensure the concrete surrounds the underside of the existing pipe work in the outfall manholes where applicable.

A section of the existing pipe will be removed and a new channel will be installed with one new rocker pipe outside of the manhole on both sides.

Precast concrete manhole rings will be lifted into place using certified man hole lifting eyes THE EXCAVATOR BUCKET MUST BE REMOVED WHILST PLACING THE MAN HOLE RINGS. Grano benching will be formed to complete the base. When possible the benching works are to be carried out before the man hole cover slab is in place, this will reduce the amount of works carried out within a confined space. Operatives entering a confined space must be trained and signed onto the confined space method statement.

Once the manhole rings have been installed, a manhole surround shutter will be set in place and concrete will be placed and vibrated around the manhole. This will then be left till the next working day before it is stripped, this is to ensure that the concrete has cured enough before disturbing it.

Any backdrops will be constructed as per the design details with full concrete surround. Suitable protection will be placed to the openings within the cover slab to prevent falls and the

area will remain fenced until the backfill works are complete. Any ground water encountered will be controlled by pumping and discharging into agreed

locations which will be agreed before any works begin. No personnel are to enter any unsuitable trench/excavation and daily inspections must be

carried out and inspections recorded weekly. These will be issued to BCEGI on a weekly basis along with all plant check sheets and also small tools and lifting equipment weekly logs.

All excavations when left open must be fenced off to prevent unauthorized access. Specified backfill will be placed in layers by the machine and once the agreed cover to the pipe

is reached the trench will be compacted by roller or vibrating plate.

5 Control of Operations

Ensure a competent and authorised person is in attendance throughout the duration of the site works.

Ensure a site induction is provided and attended by all persons involved in the works.

The operative will egress the excavation/manhole via the pole ladder/manhole steps.

Work must cease and the site supervision must be informed.

Work can only resume when the site supervision have confirmed it is safe to do so.

17 Environmental Issues

Site specific environmental issues:

1. Refuelling Activities - ACS to ensure that all refuelling operations are carried out in a designated area with fuel spill kits available on hand. Emergency procedures to be displayed at re-fuelling designated area.

2. All timber will be supplied with the relevant FSC certification.

3. Concrete wash out – The concrete wagons will wash out in the designated wash out area (to be agreed on site). This will be created by utilising a small metal skip, lined with plastic sheeting. The concrete delivery drivers will be directed to wash out in the skip. Upon completion of the concrete works, the washout/water will be left to settle and solidify. The water will be segregated and removed from the skip (usually by small pump) and disposed into an agreed soakaway area of the site. The solidified concrete will be disposed off site, with the skip, to the local recycling facility.

4. Surface water and pumping from excavations will be required and specific locations will be identified and procedures agreed with site management.
