Heritage Cases

The revetment area will be cleared to a certain extent to make it more accessible for earth moving machines. The initial clearing will be done by front end loader and/or backactor and possibly be assisted by some dump trucks. Placement of temporary works to protect works during construction. Material removed from the present revetment may temporarily be stockpiled close by or removed to an approved spoil site. Access for construction vehicles (earthmoving machines, dump trucks etc.) to the revetment site will be from the south end of the revetment – i.e. starting in the vicinity of the existing slipway. The concrete fragments and building rubble may either be spoiled off-site or crushed for re-use in the new revetment – i.e. recycled. Having achieved initial clearing and tidying up of the revetment site, reconstruction can commence. Certain construction activities will be restricted to low tide conditions only. Geotextiles may be required if the migration of sand is to be controlled. The new revetment will include a surface lining consisting of rubble/rock. Some of this rubble will be sourced from the stock pile mentioned earlier. Additional rock, probably two or three sizes of fragments, will be imported from a commercial quarry. A fleet of dump trucks will transport rock from the quarry to the site. This material will, ideally, be tipped directly onto the revetment site, starting with the smallest size fragments. Material will be spread and levelled by front end loader or backactor. This process will be repeated for the next size of fragment until the final layer of rubble has been completed. The complete site (revetment, adjacent road and car park, Contractor’s lay down area) will be cleared, re-instated and rehabilitated before the contractor departs. Cognisance will be taken of the findings in the site archaeological report during construction activities.
