Had-Fab Ltd provides a design, fabrication, galvanise, packaging and delivery service, for the supply of high voltage substation support structures to the power supply industry, they also manufacture transmission towers, radio towers and masts.
That said, Had-Fab are currently using Tekla Structures to model the new statue designed by sculptor Antony Gormley. His sculptures, often based on casts of his own body, adorn public spaces and galleries across the country, from well-known works like 'Angel of the North' to his newest creation 'Exposure'. Exposure, a 25.6m high statue depicting a crouching man is due on site in the summer of 2010 in Lelystad, Holland.
Exposure time-line
 August 12th 2010
Had-Fab complete the site erection of Exposure in Lelystad, Holland. Rumour has it that the Queen of Holland will perform the opening! |
 July 2010
Latest news of the site erection in Holland sounds promising as the Hab-Fab team announce, "The work is progressing very well and ahead of schedule, we are very pleased." |
  May 2010
A very important junction in the journey has been reached. The trial assembly is now complete as the head gets attached. |
 May 2010
Had-Fab reach the end of the trial assembly, the head will be built in one piece in the next few weeks and lifted on to the structure to complete the trial build. |
 April 2010
The Hab-Fab men undergo a refresher course on rope access which will be an essential part of both the trial and final assembly. They also practiced the emergency rescue procedure in case anyone ever gets into difficulty during the build. |
 April 2010
We're now approaching a very important stage of the project, Had-Fab will be finishing fabrication of the whole sculpture by Friday 2nd April! |
 January 2010
Bottom quarter of structure has been successfully erected. Some parts have been galvanised, any parts not currently galvanised will be dismantled and galvanised before any further erection takes place. |
 November 2009
The modelling was completed in November 2009, after there were several stop / starts with the modelling during the early stages due to artist and engineer design changes. We estimate the total modelling / drawing time from when we received the final design to completion to be 8 months work. |
  September 2009
The steelwork is marked so it identifies which parts connect which nodes, Had-Fab have also produced part 3D Tekla Structures drawings and level plans with the nodes labelled. The full Tekla Structures model on the laptop is used to clarify any area of confusion.
Had-Fab designed, fabricated and erected a crane structure with foundations, and provided a foundation for the structure at trial erection using 540 tonnes of concrete. |
 Summer 2009
On-site for two weeks during the summer of 2009, installing the foundation steelwork. |
 January 2009
NC data exported to FICEP machine from the Tekla model to produce steel angle profiles. Tekla structures interfaced with Steel Projects Winsteel to produce machine codes for the FICEP angle line.
The material is punched and sheared to length, in total there will be 32,000 holes  punched in the angle profiles and the total weight of the structure will be 60 tonnes. Had-Fab then shape the material to form up to 550 nodes consisting of up to 27 angles meeting together to form locating points around the structure. |
 Late 2008
Exposure is fabricated from RSA (angle) sections, as are transmission towers but that is where the similarity ends. The structure is a complex mesh of angles all with random rotation. Had-Fab's workshop supervisor Alan Robertson worked closely with draughtsman Rab Rathie and the Tekla Structures model to develop a jig concept. Once the jig was built they decided the Tekla Structures Viewer was the best option for getting the necessary dimensions needed, they use the same procedure for every node.
"I feel it was a necessity to use the Tekla Structures Viewer, all the angle dimensions and check sizes would have been very confusing on a assembly drawing." Paul Mair, Had-Fab Ltd. |
During 2007
Initial design models were refined and passed between the design software and Tekla Structures as well as between the different parties involved; Eelco de Winter of Royal Haskoning, Had-Fab, Tekla and SCIA. The Tekla Web Viewer was also used to feed back information and confirm rotations and positions of the angle members. |
November 2006
Had-Fab purchase their first Tekla Structures licence. Tekla Structures version 13 was used for the main model and version 14 used for models of individual nodes. |
  Summer 2005
Simon Harrison, Managing Director at Had-Fab Ltd was approached by Antony Gormley, who was looking for a steel fabricator with experience of tower fabrication to take up the challenge of his latest work.
