Advice

However our key service offering is Advice. Excellent advice.

Competencies and Capability Statements

I have also become interested in Competencies and Capability Statements. Go to the Competency pages for more information and an outline history of my involvement.

Information Flow, Management, and Modelling

I became aware of Building Information Modelling, (BIM) and started promoting it within Hyder in 2010.  I now have a much better understanding of the real meaning of BIM and have accordingly changed how I refer to it, so as to more accurately reflect the intent. Especially losing the word Building as  it is by no way restricted only to buildings. Go to the Information Flow, Management, and Modelling pages for more information.

Top Down ConstructionSectors

Top down construction and concrete frame

The adjacent image is an example of top down construction. Top down and concrete frame were used in construction of The Brooks, at Winchester. A difficult project for numerous reasons, including a water table of about 1m below the surface. The bottom basement was a lot deeper than that. The diaphragm wall and base floor joint had not been  designed to be watertight even though it was several meters below water table. Water was found to track alone rebar and jet out of pin holes in the concrete slab. This was a interesting technical problem which led to a significant contractual dispute.

Jacked Structures and Tunnelling

Another example of unusual construction methods is Jacked Structures. Jacked Structures is a generic name to include several similar activities including, Jacked Box Tunnelling, Bridge Jacking, Thrust Boring. A Jacked Structure method of construction is normally restricted to railways because the high cost can be offset by the reduction in disruption, but it has occasionally been used for motorways.

The technique is best shown with moving images, but apologies in advance if YouTube is blocked on your network.

There are several methods, names, and propriety friction reduction techniques for Jacked Structures. One of the English participants is John Ropkins. An extract from John's website, under Publications, states, 'T.E. Clarkson and J.W.T Ropkins - 'Pipe-jacking applied to large structures' Proceedings, Institution of Civil Engineers, Part 1, 1977, 62 (Nov), 539-561, London, UK '. Ivan Hurst worked for Cementation Projects, who also held one of the Patents, whilst Ted Clarkson was the Managing Director. At Stonebridge Park, in London, Cementation Projects, in conjunction with a number of sister companies, built six bridges under railway lines for British Rail, to enable the re-alignment and improvement of the North Circular Road. A number of methods were used including traditional, jacked box tunnel, and jacked (thrust) 3 tier abutments and pier followed by composite bridge deck slide. Ivan was the Project QS for the project. Ivan was also involved, to a lesser extent, with the jacked twin-box tunnel in Wilmslow, Cheshire following the liquidation of Jacked Structures. Cementation Projects were advisors in the early stages of the Boston 'Big Dig' Project, and Ivan was the QS for Cementation Projects' element.

Ivan Hurst has more recently been involved with a number of significant tunnelling schemes including Dublin Metro, Sydney Metro and London's Crossrail.

Highways

We have more experience in 'Roads and Bridges' than either 'Top down and concrete frame building' or 'Jacked Structures'. Ivan has been significantly involved in the implementation of about a dozen major Highways schemes. Earthworks and Structures are of particular interest.

Railways

However, the main sector we cover is railways. That includes heavy rail, light rail, metros, and trams. We cover many elements, either directly or with our associates. Ivan held the post of Estimator for Rail Systems and Power for Crossrail. That is a wide portfolio with a very significant budget.

Examples of projects undertaken in this sector are listed in the Projects, Programmes and Commissions page.
