Time: 10.30am Organisation: Landpac Ground Engineering Title: High impact compaction technology and ground response monitoring and verification Presenter: Dermot Kelly Landpac, a Johannesburg-based company with operating centres in Australia, China, Saudi Arabia and the UK, started out on Hong Kong's Chek Lap Kok Airport. Wobbly rollers at the heart of the High Energy Impact Compaction (HEIC) system have cam-like lobes which deliver massive compaction force to the ground as they are towed across a site:
15kJ from the five sided machine as a series of relatively flat impacts and 25kJ from the three sided roller which forms a deeper, trough-like compaction pattern. Both fill and natural materials can be consolidated by the technique. Landpac says proof measurement of 100% is possible.
Time: 11.30am Organisation: Resiblock Title: Sealing of small element paving systems - structural and environmental benefits Presenter: Paul Lamparter Resiblock claims stabilising the sand filled joints in block paving with a specialist prepolymer urethane (SPPU) prevents erosion by maintenance equipment, improves safety and reduces claims due to tripping accidents. In addition, bedding failure due to sand liquefaction and freeze/thaw movements is prevented while the structural integrity of heavy duty pavements is improved. SPPU also controls joint infiltration by surface water and hydrocarbon spillages, as well as inhibiting the unwanted growth of weeds and grasses. These issues will be discussed in Resiblock's seminar, along with safety of black and white block paved roundabouts and latest academic research.
Time: 12.30pm Organisation: Weeks Group Title: Sustainable pavement technologies Presenter: Derek Fordyce If the pavement industry is to progress successfully in the future it will require materials producers, consultants, contractors and end users to work together in collaboration to develop environmentally sustainable materials, technologies and techniques that offer more effective ways of delivering pavement engineering solutions. Pavement Technology is a new venture between Heriot Watt University and the Weeks Group aimed at developing the next generation in pavement technologies. The seminar will look at these future technologies and their implications.
Time: 1.30pm Organisation: Geofirma Soils Engineering Title: Typical applications and constructrion procedures for lime/cement stabilisation of soil Presenter: Jonathan H Smith, director, Geofirma Soils Engineering Increasing taxes on the disposal of surplus soil and the import of stone aggregates are making soil stabilisation a preferred method for site preparation, as it utilises the existing material to produce structural fill and sub-base layers for ground slabs and external works. The majority of soil stabilisation in the UK is undertaken on commercial developments, but its use is increasing on trunk roads and public projects such as the Manchester Commonwealth Games stadium and the Channel Tunnel Rail Link. This seminar will review typical applications, design and construction procedures and overall benefits relevant to this method of ground treatment.
Time: 2.30pm Organisation: Thomas Telford Title: The New Engineering Contract Presenter: Professor John Perry This seminar will explain the principles of the NEC, the extent to which it has been used within the construction industry and how it enables greater certainty in achieving improved project results. The NEC was launched in 1993 in response to changes in the nature of commercial relationships in the construction industry. Contracts and contract management have changed significantly, with the construction industry moving away from the 'traditional' adversarial approach to one of partnering and co-operation. The NEC embraces the concept of partnering by encouraging employers, designers, contractors and project managers to work together to achieve all parties' objectives.
Time: 3.30pm Organisation: Association of Consulting Engineers Title: Clients and consultants - working well together: an ACE Best Practice seminar Engineering consultancy has undergone a period of dramatic change with more competition and increased emphasis on best practice. This, the ACE's first Best Practice programme seminar, will draw on examples from the ACE's Client Best Practice Award and address the critical issues to working successfully in partnership with clients: What are clients looking for? How can we work with clients to ensure the best use of engineers and engineering? And how can consulting engineers and others input effectively to projects and contribute to clients' thinking? ACE invites Civils 2002 visitors to debate these issues at its seminar.
