General Building

Strancally Castle. County Waterford

by | May 22, 2017

Contract Details:

Cumnor Construction Ltd. carried out the role of Works Contractor and PSCS for this project.

This contract was for the construction of a new swimming pool connected to the existing castle. In keeping with the historical nature of the castle, and the importance of keeping the new pool adjacent to the existing castle, the pool was constructed below ground.

The work consisted of the construction of a 25m long indoor/outdoor pool with a rising floor that became an outdoor terrace when the pool was not in use. A bar and poolside lounge, jacuzzi, spa, gymnasium and professional treatment room were also constructed.

Limitations on levels demanded a creative roof solution. This entailed the use of long-span precast units to maximise span without the need for internal columns.

A large skylight was constructed with glass beams to support it. One end of the pool was separated from the outside by a fully automatic frameless glazed door that sliced through the pool water surface.

Cliff Stabilisation. Ardmore, County Waterford

by | May 22, 2017

Contract Details

Cumnor Construction Ltd. carried out the role of Works Contractor and PSCS for this project.

This contract required specialised work involving the installation of soil nails/ground anchors and the application of spray applied concrete to the cliff walls and slopes.

Environmental control procedures were implemented so as not to contaminate the sea water. A temporary platform had to be constructed to a level above the highest tide while the work was being completed. This was constructed using Rock Armour and netting. The existing slope face was cleared of all vegetation and loose material. The face of the slope was cut back and graded for the full height so that the toe of the shotcrete rested on the rock and was supported for its full height by the rock. Runoff from grouting and shotcreting was prevented from entering the water.

53 self-drilling hollow bar soil nail anchors were installed and proof tested.  Drainage was required to the cliff front face behind the shotcrete. Additional drainage to the body of the cliff soil required drilling into the cliff face and installation of PVC drains. Shotcrete was applied to the cliff face and was coloured to help blend into the surrounding cliff.  The shotcrete was reinforced in its centre using two layers of 2.4mm galvanised triple twist wire mesh.

Seawall Stabilisation. Youghal, County Cork

by | May 22, 2017

Contract Details

Cumnor Construction Ltd carried out the role of Works Contractor and PSCS for this project.

The work consisted of embankment reconstruction, netting, shotcreting, soil nailing and installing ground anchors as well as the construction of reinforced concrete retaining walls and gabion retaining walls. Soil nails were installed to reinforce the sea wall. A reinforced concrete retaining wall was constructed at the base of the wall and anchored into the rock using ground anchors. These soil nails/ anchors were grouted and tested. Records of these results were tabulated and submitted to the client. A large steel frame was constructed to the seawall, bolted on concrete reinforced pads, and anchored into the rock.

All of this work was scheduled to coincide with low tides. A safe means of access to the base of the wall had to be provided as the waters encroached onto the working area at high tide.

The area was environmentally sensitive. Adequate protection measures were put in place during the construction period.

Traffic Management measures were place for the duration of the works.   Access points maintained to private dwellings. The traffic management plans were drafted and submitted to Cork County Council and An Garda Síochána prior to works commencing.
