Conference Day Two : Friday, 30th June 2017
9:00 am - 9:30 am Coffee & Registration
9:30 am - 9:40 am Opening Remarks from Conference Chairperson
9:40 am - 10:20 am Looking at the Efficient Use of Screw Piles as Deep Foundation Elements
10:20 am - 11:00 am Keeping Clients Happy, Meeting Needs and Excelling Expectations
- Addressing CLL as a company and how they meet clients need on time and on budget
- Understanding how CLL approach a new project
- Outlining previous piling projects including key learning’s on the following jobs:
- Petone Sheet Piling
- Installation of Sheet Piles with the ABI Rig
- Pile Driving Concrete piles – Samoa Consulate
- Down Hole Hammer
11:00 am - 11:30 am Morning Tea
11:30 am - 12:10 pm Using Large Diameter Piles to Speed Up Construction
The terminology around large diameter bored piles is experiencing new meanings with pile diameters of approximately 3m being now used. Such large diameters can provide significant cost reductions with respect to both direct costs and construction program. However, there are specific aspects of pile performance that should be accounted for in the design and their effect on the superstructure. As part of this presentation, the following topics will be covered:
- Benefits and disadvantages of large bored piles
- Design aspect of large diameter bored piles
- Pile performance
12:10 pm - 12:50 pm Solution Clinic
Solution clinics are designed to give participants strategies and tools to deal with their most pressing challenges. The room will split into tables, where each table member will share their biggest challenge, before collectively deciding which issue to investigate in more detail. The table will then elect a facilitator/note taker who will record the topic being explored and the ideas o the table. After 40 minutes of discussion, the facilitator of each table will then report back to the rest of the audience their problem and potential solutions.
12:50 pm - 1:50 pm Networking Lunch
1:50 pm - 2:30 pm Performance of Rammed Aggregate Piers as a Soil Densification Method in Sandy and Silty Soils: Experience From the Christchurch Rebuild
- Data comparison of pre and post densification using RAP to measure the degree of improvement function of soil types (mainly sand and silt);
- Influence of the improvement bulb below the treatment depth;
- Influence of the replacement ratio on the degree of improvement;
- Level of improvement function of confinement for clean sand; and
- Time component and measured densification for silty soils.
2:30 pm - 3:10 pm An Overview of the Joint Venture Between Downer and Soletanche Bachy on the City Rail Link Contract 1
3:10 pm - 3:40 pm Afternoon Tea
3:40 pm - 4:20 pm Design of Geotechnical Structures and Foundations for Resilience
- Repair of bridge foundations using grout injected hollow bar Micropiles
- Overcoming limited access for piling equipment and avoiding closure of site
- Static load testing
- Addressing high water table and difficult ground conditions
- High capacity grout injected Micropiles to eliminate risk of installing driven or bored piles.
- Lowering cost and reducing the overall work program using Micropiles
4:20 pm - 5:00 pm Transmission Gully
The Transmission Gully project involves constructing a 27-km four-lane (two in each direction) motorway from MacKays to Linden. There will be interchanges at MacKays Crossing, SH58, eastern Porirua (James Cook), and at Kenepuru.
The project is part of the Wellington Northern Corridor and is a vital cog in the region’s transport system. It is designed to provide a critical and resilient lifeline to Wellington in the event of an earthquake or other major disruption. Importantly, it is a catalyst for local economic development.
