Structural Engineer

Beca Limited – Oct 2007 – Present

85Molesworth St. Wellington

Construction Monitoring Works:

Selected Project List:

1.  Strengthening Totara Park Bridge (Project Value: 500, 000)

  • The scope of works includes installation of reinforced concrete shear keys to abutments and steel jackets on all piers.

2.  Construction Smart Motorway Project, Wellington - (Project Value: 50M)

  • The scope of works includes Geotechnical Investigation, Planning and Structural Input, ATMS / ITS Design and Design Management

3.  Construction of Akatarawa Bridge (Project Value: 2.2M)

  • The scope of works includes the replacement of existing bridge which was damage during heavy flooding with a 42m single span bridge.  The very first weathering steel bridge structure constructed in New Zealand.

4.  Construction of Datacom Expansion Abel Smith (Project Value: 5M)

  • The scope of works Geotechnical investigation, design and construction of new structural steel platform on piles to house new chillers and mechanical equipment.

Typical Tasks:

  • Review of the design and for construction drawings.
  • Review of the specification requirements to be familiar what site required. 
  • Review concrete design mix to ensure compliance to the specification. 
  • Review construction methodology per project main activity and discuss with the design team if at some point work method are not feasible and come up with recommendations
  • Responsible for responding to contractors query and provide them immediate solution to every problem encountered on site to prevent work delays. 
  • Responsible for the construction monitoring and reporting to designer by issuing the site visit report.
  • Responsible for gathering all QA work necessary for signing of PS4.

Brief Summary on the Typical Challenges on site:

  • Work method sometimes does not works in terms of stability of the structure to be lift in the event of an abrupt earthquake event.
  • Contractor encountered a contaminated soil that smell like a diesel/petrol and a lot of building services are within the project footprint.
  • During piling within the sea shore line, the founding depth achieved but the type of soil extracted at the founding level (9m depth) still soft and does not match with the bore test data.
  • During concrete pouring of the foundation - concrete mix was too slurry and slump reaches approximately 160-170.
  • Delivery of concrete mix sometimes delayed.
  • Possibility of undermining the existing structure by excavation to the inner extent of the existing structure. 

Action:

All highlight issues has been discuss primarily to Beca design team and came out with at a minimum 2 solution/s before issuing Engineers Instruction (EI) to the contractor.

Issues that will trigger health and issue to all workers and possibly to the public, we basically advised contractor for a halt and to put all necessary public notice and cordon the area.   Sample of contaminated soil send to specialist for further study/assessment.

Suggested to stop the excavation and call Geotech engineer to come to the site to investigate the extracted soil.  It was decided to push more up to 9.4m depth until base was felt hard and Geotech suggest to drive 100mm more to minimise inflows and possibly concrete pushing out of the steel pile casing.

To prevent damage to existing underground services during piling or excavation, the use of Hydro Vac excavator were suggested.

Half of the truck of concrete was rejected and a new batch of concrete arrived with 120mm slump.

Excavation is more common issue in an upgrade or retrofit job, we always suggest to provide temporary propping and if possible to shotcrete the outer face of the excavated ground adjacent to the existing structure to prevent ground collapse.

Any other minor issue are dealt on site via verbal instruction and follow-up with EI and advice contractor to send photograph to prove that the work has been done as per site instruction.
