PTA Awards 2016

The very first Post Tensioning association awards dinner took place at Tottenham Hotspur Football Club on the 21st April 2016. The evening was a great success and enjoyed by all 130 + guests and our award entries showcased some of the very best applications of post tensioning in the UK. The PTA presented four awards that were judged by leading industry experts. Full details of award winners and the judging panel are below.

Best National Project 2016: Praeter Engineering - THE CLARGES


The Clarges Development (At Piccadilly) - Jack Slab

Block 'A' has 3 basements below ground floor, with B3 sitting 13.345m down from the ground floor. In order to achieve a tightly programmed basement dig a new philosophy was adopted on the traditional 'top-down' solution. This consisted of casting the B2 slab directly on prepared ground. A separation membrane was then installed prior to casting the B1 slab directly on top of the B2 slab. In order for the basement excavation to B3 to progress rapidly without the impediment of restricted headroom, the B1 slab was permanently connected to plunge columns whilst the B2 slab was temporarily hung from pre-installed tie bars from the B1 slab.

On completion of the excavation the B2 slab was transferred from the temporary supporting tie bars onto strand jacks where it was then lowered down into its permanent position before being connected to the column supports.

Consultant(s) - Waterman Structures
Frame Contractor - Expanded
PT Designer - Praeter/Expanded
PT Installer - Praeter/Dorman Long

The judges were looking for an entry that celebrates the excellence in use of post-tensioning, exploits the attributes of post tensioning, innovation, sustainability and value for money and the Clarges was indeed a worthy winner

Project of special recognition 2016: Ramboll - THE HAMMERSMITH FLYOVER STRENGTHENING WORKS


Hammersmith Flyover - Second Phase Strengthening

Hammersmith Flyover is a precast segmental bridge with pre-stress which is partly internal and partly external. Iy was finished in 1962 with electric heating to obviate the need for de-icing salt but has been salted for 50 years.

The pre-stress was deteriorating seriously and emergency strengthening to critical sections, known as "Phase 1", was rapidly installed in 2012 enabling full reopening for the Olympics. It was decided that new pre-stress should be installed to make it independent of the original and allow this to become completely ineffective.

It is believed to be the first time full replacement pre-stress has been installed in a bridge where it was impossible to remove the original. Doing this in the very confined space forced an unusual amount of navel solutions developed with extensive collaboration between Freyssinet and the designer.

Submitted by - Ramboll UK
Owner - TFL
Consultant(s) - Ramboll/WSP-PB
PT Designer - Ramboll/WSP-PB

The project entry from Ramboll for the Hammersmith flyover was deemed to be of such high standard and so unique that it deserved a category of awards all of its own. This award was created as a one off to showcase this project and the skills and innovation involved in delivering it. Although Ramboll received the award for the entry the project does showcase the excellence of all parties involved
This was a true collaboration of industry experts to deliver a technical complex and challenging project.



This was the first new award of the evening and was introduced as a way of recognising the excellent work that PTA members do in attracting, training and developing new talent into the post tensioning community.

The judges were looking for examples of how well the trainee has applied themselves and their consistency, had the trainee succeeded in developing themselves both professionally and personally, whether the trainee had received good reports from colleagues, mentors and course tutors and whether the trainee was a valued member of the team.

The submission from WSP for Nathan Fieldsend was of extremely high quality and clearly demonstrated that Nathan was not only following a clearly defined and well structured training and development plan but was excelling in both the eyes of his team and his manager.

Outstanding Contribution - TERRY BRADLEY
