Kalk Bay St James : Main Road Rehabilitation, Newsletter 17

As you are aware, the rehabilitation of a 4.5 km portion of the Main Road from Atlantic Road in Muizenberg to Clovelly Road, Clovelly has been underway since March 2008. The purpose of this Newsletter is to provide users of the road with relevant information concerning Phase 1 and Phase 2 of this project.

2.1 PHASE 1 CONSTRUCTION (Canty House to Leighton Road)

PROJECT PROGRESS – PHASE 1

2.1.1 Completion of Sections 1 and 2

There are some items of remedial work still outstanding on Sections 1 & 2:

• Minor footway repairs
• Seating of manhole covers
• Correction to kerb at Carisbrooke entrance
• Completion of air valve chambers
• Installation of flashing pedestrian warning signs
• Corrections to asphalt surfacing
• Completion of a sewer lining repair and the fixing of internal backdrops

Once these items are substantially complete a certificate of practical completion will be issued.

2.1.2 Progress on Section 3 southbound:

Bulk Water Main

• Completion and pressure testing of the main took place on 24 March 2011.
• The installation of the cross connection between the old and new mains is planned for 31 March 2011.
• The cross connection will require an interruption to the supply to the deep south and consumers will receive the necessary notification.
• As a result of the rock and other factors, the project is a further three weeks behind schedule. Valve Chamber on 600 Water Main
• The valve chamber on the 600 water main was completed before the December holiday.
• The main valve, scour and cross-feed valves have now been installed.

Sewers

• The auxiliary sewers in this section are 95% complete.
• The cross connection to the manhole in the carriageway at Leighton Road will be installed after normal working hours to minimise disruption to traffic.

Sewer Rising Main

• The 450 diameter sewer rising-main will be installed in the old 500 water main once the new 600 main is in service.
• The HDPE pipe will be butt welded and installed in four lengths varying between 160 and 200 metres.
• This operation is expected to take a week and will be followed by the connection to the Dalebrook sewer pump station.

Road Construction

• Road works are underway in the areas where the new water main is complete and unaffected by the installation of the stormwater crossings and the entry pits for the sewer rising main.
• The macadam sub-base and stone kerbs are 25% complete.
• Brick paving to the parallel parking bays has star

PHASE 2 CONSTRUCTION (Leighton Road to Kalk Bay Harbour

3.1 PROJECT PROGRESS – PHASE 2

Section A Southbound

Section A Southbound is from Leighton Road to Holy Trinity Church.

Work started officially on 17th January 2011 and includes the following:

  • Approximately 120 metres of the 600mm diameter bulk water main.
  • Roughly 100 metres of stormwater pipes from 300mm to 600mm diameter with associated manholes and catchpits.
  • The reconstruction of the parking area opposite Holy Trinity Church, including hard and soft landscaping, irrigation and area lighting, which will accommodate 62 vehicles.
  • The construction of 400 metres of half width road including parallel parking for an additional 45 vehicles.

    •Construction is on programme and, so far, the excavation for the water main is easier than expected as only a small quantity of rock has been encountered. However the start of pipe laying has been delayed a few days due to the importation of rubber pipe seals.

    Peripheral projects

    • In addition to the reconstruction of the Kalk Bay section of Main Road, the Phase 2 contract includes the following:

  • Upgrading of the Ou Kaapse Weg and Steenberg Road intersection to provide an additional right turn lane;
  • An additional lane at the Royal Road / Axminster Road intersection in Muizenberg.
  • The work also includes changes and upgrading of the traffic signals and repositioning of the street lights at both intersections.

    • These peripheral upgrading projects are considered essential to ease the congestion resulting from the Main Road upgrading and improve the long term capacity of these intersections.

    3.2 PROJECT PROGRAMME – PHASE 2

    Work on Phase 2 (Leighton Road to Kalk Bay Harbour) commenced on 17 January 2011.

    The anticipated completion programme for Phase 2 is set out below. Please be advised that this is subject to change at the discretion of the Contractor should it be deemed to be beneficial in terms of timing.

    The official contract period for the Phase 2 project including special non working days, is from January 2011 to March 2013, however the approved phasing is as follows:

    1.Section A: Southbound (400m) – January to May 2011
    2.Section C: Southbound (250m) – Jun to August 2011
    3.Section D: Northbound (250m) – August to November 2011
    4.Section B: Northbound (400m) – November 2011 to February 2012
    5.Section E: Southbound (250m) – March to May 2012
    6.Section F: Northbound (250m) – June to August 2012
    7.Section G: Southbound (200m) – September to November 2012
    8.Section H: Northbound (200m) – November 2012 to March 2013

    There is a distinct possibility, depending on resources, of starting Section B Northbound at the same time as Section C Southbound. This would have a positive impact on the completion of the whole project.

    2.3 PROJECT PROGRAMME – PHASE 1

    Work on Phase 1 is currently behind schedule. The anticipated completion date for Phase 1 was initially 4 November 2010 but due to adverse physical conditions encountered with this section (difficulty breaking the hard quartzitic sandstone), completion is now scheduled for May 2011.
