EXCAVATION, EARTHWORK AND FILLING

APPROVED BY:

QEHS MANAGER

ACTION

VERIFY

1. SCOPE

This procedure provides a standardised framework for the control of excavation, earthwork and filling to ensure compliance with conditions of contract and contract specifications.

2. PROCEDURE

.1 All excavation, earthwork and filling will be carried out in accordance with the specification detailed in the project contract documentation. In any circumstances where specifications are not provided or they are in any way incomplete, the matter shall be referred back to consultant for additional information.

.2 Method Statement

A method statement will be prepared and approved where deemed necessary, and may include:

i) Site plan showing the location of spoil heaps for temporary storage and if appropriate permanent storage area.

ii) Type of plant and equipment to be used.

iii) Means for keeping excavations free of water.

iv) Method of trench supports.

v) Method and sequence of excavation to ensure that no damage is caused to adjoining structures and property. If there is potential for damage to adjoining structures and property, the type of preventative measures should be indicated.

vi) Temporary support arrangement of adjacent structures and services passing through the site.

vii) Method of compacting fill and testing procedure.

Health and Safety requirements.

Any other special requirements.

Project Manager

Method Statement

.3 Existing Utilities

Liaise with all public utility companies e.g. water, electricity, telephone sewerage and surface water etc. to ensure that all the available information on the location of utilities and underground services through and adjacent to the site of the excavation is obtained.

ii) Ensure that utilities and underground services are located on site using markings, which are clearly visible. Ensure those plant operators and operatives involved with the activity are fully aware of the location of the various utilities and underground services and their respective depths.

iii) Where deemed necessary, excavate trial holes to establish the precise location and depth of services.

iv) Plant operators must be aware of overhead cables. Use height control indicators where necessary.

.4 Site Survey and Grid of Levels

Prior to commencement of any excavation work, a level survey will be carried out to confirm the information included on the contract drawings and to provide an accurate record of existing ground levels for the calculation of quantities.

.5 Disposal of Surplus Excavated Material

Prior to any surplus excavated material being removed from the site, documentary evidence of “approval to tip” must be obtained beforehand from the relevant government/municipal departments and the owner of the land where the material is to be tipped.

.6 Adjoining Structures and Property

Prior to the commencement of excavation work, a detailed dilapidation survey will be undertaken to record the existing condition of the adjoining structures and property. Where necessary the survey may include photographic records.

Approval to Tip

This survey should be carried out in co-ordination with and involving the participation of the Consultant’s representative and the representative of the owners/occupiers of the adjacent property.

.7 Excavation Work

Excavation shall be allowed to progress to the designed formation level less 50mm (unless specified otherwise). The remaining 50mm shall be carried out by further careful excavation to avoid disturbing the formation level.

After reaching the designed formation level, Consultant’s representative shall be requested in writing to inspect and approve the formation prior to the commencement of any subsequent activities.

iii) Great care shall be taken to minimise noise, vibration and dust pollution, which can cause nuisance and damage, particularly if the site is located in a built-up area.

iv) Sides of all excavations should be properly supported using an appropriate method as detailed in the Method Statement.

.8 Filling

Prior to commencement of filling, the Consultant’s representative shall be requested in writing to inspect and approve the fill starting level.

ii) Filling shall be carried out using approved materials in accordance with the specification which can either be selected from the material on site or imported from selected and approved sources.

iii) Filling shall be carried out as per approved method and as per the contract specification.
