We've had a ball

_space group's Directors get ready for one of the 'must attend' nights of the year in Newcastle.

Friday 14 May saw the fourth annual charity ball we've thrown in Newcastle, and we're happy to report that we raised £20,250 for this year's chosen charity, Children North East.

The Think Pink ball, which is supported by _space foundation, is turning into one of the 'must attend' nights of the year in Newcastle, and this year was no different, as over 200 members of the construction industry turned out for a night of fun and frolics in the name of raising money for a good cause.

This year, the focus of Children North East's fundraising effort has been the WEYES project. WEYES (West End Youth Enquiry Service) was set up by Children North East for young people aged 11 - 25 to offer advice, information and support on a number of issues, from employment and training, to education, health and relationships. While a valuable project, the WEYES building was in need of TLC, in the form of renovation and extension, and _space group has stepped in, agreeing to renovate and extend the building, so that young people in Newcastle have a great space that they can visit when they’re in need of some advice. While we're supplying our services for free, there are other costs associated with a project like this and the Think Pink ball has gone a long way to helping to pay those costs.

We'd really like to thank everyone who came last Friday, and supported Children North East and the WEYES project. We hope you had as enjoyable an evening as we did, and we look forward to seeing you all again for this event next year.

_space group Associate Technical Advisor, David Savage, at Constructionarium 2010

_space group feels strongly about aiding the development of students preparing to join the industries in which we work, and investing in future skills. One of the ways we help is via Constructionarium - a five day working field course based at former air base RAF Bircham Newton, King's Lynn, designed to provide a practical experience of construction for students.

Several universities send groups of students to Constructionarium to understand what it's like to work on site and help them to prepare for the construction industry. _space group has been acting as technical advisors for students from Northumbria University taking part in the project this year. David Savage, our Associate Technical Director, spent last week at the Constructionarium site with the Northumbria University students, advising them on their four projects - 1:10 scale versions of the Swiss re building (better known as "The Gherkin"), the canopy roof and access shaft for Naples Airport Underground Station, the Barcelona tower, and a scaled down version of the Millennium Galleries project in Sheffield. Below is a short diary he kept on the construction of each project.

Project 1 - The Swiss re building/"The Gherkin"

Day one, Monday 26 April:

The students dug an excavation hole to the underside of the foundation level. They installed formwork for the core base and started to assemble the diagrids that give the building its distinctive shape. These will be added into place later on in the week, in large sections, rather than individually.

Day two, Tuesday 27 April:

Flexible plastic formers have been used to form a run for the concrete base and despite a substantial amount of timber propping, these formers have been found to not be strong enough and has led to the first concrete pour for the base of the structure becoming deformed. The students have also had to contend with a lack of concrete, and schedule an urgent delivery for the morning.

Day three, Wednesday 28 April:

The second concrete pour has been completed, and due to the deformation caused by the plastic formers, the dimensions have been checked and re-checked to ensure that the foundation could support the diagrid baseplates. The results were positive and the students have been able to mark out the baseplate positions for the diagrid structures to be fitted to the foundations.

Day four, Thursday 29 April:

Despite experiencing more problems with broken drill bits, the students have been able to hoist the upper floor diagrids into place and bolt them to the base frame. They used a scaffold and crane to achive this and worked until 6.30, past the end of their working day, to ensure they were on schedule to complete the next day.

Day five, Friday 30 April:

The project was completed at approx. 3.30 pm. Despite some problems, the students have worked hard to pick themselves up and get on with the job.

Project 2 - Millennium Galleries

Day one, Monday 26 April:

The students have prepared excavations for foundations and formwork of the structure.

Day two, Tuesday 27 April:

Concrete for the structure has been cast and the students have completed construction of the shutters. They've also tied lifting hoops to the reinforcing cages so that they can avoid the risk of the hoops pulling out - a problem last year's students experienced.

Day three, Wednesday 28 April:

The students have prepared the shuttering for the roof section, in preparation for casting the roof in one piece.

Day four, Thursday 29 April:

Pre-cast walls end walls have been lifted into place. The students have had to break out part of the foundation to accommodate one of the walls as a result of the foundation former moving slightly on day two.

Day five, Friday 30 April:

Project completed mid-afternoon.

Project 3 - Naples Airport Underground Roof

Day one, Monday 26 April:

The first set of precast rings are in place and the excavations for the ring beam completed. The structure's timber ribs have all had baseplates fitted.

Day two, Tuesday 27 April:

Precast rings have been placed and sunk. The students have also placed reinforcement and column formers into the structure.

Day three, Wednesday 28 April:

Students have sunk the precast rings to the correct depth, set the scaffold rails and poured concrete to the columns.

Day four, Thursday 29 April:

Baseplate holes have been set out and drilling for fixings carried out. However, some of the columns are out of position and this may be due to the movement of the concrete during its placement yesterday, as the formers were not held at the base.

Day five, Friday 30 April:

The students completed the project by mid-afternoon.

Project 4 - Barcelona Tower

Day one, Monday 26 April:

The project has proceeded well, despite some survey equipment not being available on the first day. The students haven't let these problems delay them and have instead used trigonometry and tape measurements to set out their project.

Day two, Tuesday 27 April:

Central column based and reinforcements were put in place. The students also continued with the pre-fabrication of the external metal structure (started yesterday), which was a complex and very time consuming process.

Day three, Wednesday 28 April:

A scaffold and shuttering were both erected and two seperate pours of concrete were completed. The students also cast the perimeter foundations for the cable ties and provided temporary props for the central column.

Day four, Thursday 29 April:

The scaffold was lifted and the final pour of concrete for the central column cast. The students were also able to add external features - a _space sign and seating, painted "_space pink".

Day five, Friday 30 April:

Shuttering was struck, the scaffold adjusted, main structure lifted into place,tie cables installed and tensioned. By mid afternoon the shuttering was removed and the project completed.
