Building a giant tetrahedron and constructing a working crane arm made solely out of paper - just a couple of the challenges taken up by pupils from Years 4, 5 and 6 in the 'Grand Designs Challenge' held last week.

Sixty children from 12 different schools in Pembrokeshire enjoyed a series of construction and engineering trials in the event at Narberth CP School.

The event was held by Pembrokeshire County Council and the Construction Industry Training Board (CITB) with support from the engineering and construction group Costain.

Taking part were Narberth CP School, Fenton CP School, St. Marks Church in Wales School, Ysgol Wdig, Ysgol Glannau Gwaun, Milford Haven Junior School, Manorbier Church in Wales VC School, Saundersfoot CP School, Brynconin CP School, St. Teilo's Catholic Primary School, St. Florence Church in Wales VC School, and Pembroke Dock Community School.

Clr. Huw George, cabinet member for children, young people, learning and the Welsh language, said the day was very successful.

"The aim was to raise the aspirations of young people and to give them a taste of the skills necessary to work in construction and engineering," he said.

The winners of the gold award were Saundersfoot CP School pupils, Billy Parcell, Charlie Law, Maisie Price and Isobel Lander.

The silver award was won by Narberth CP School pupils, William Brandrick, Harvey Yau, Isobel Lloyd and Theo Knipe.

The awards were presented by Clr. George, Roger Sylvester (CITB) and Phil Baker from Costain, who provided them.

The event was organised by Community Focused Schools, part of Pembrokeshire County Council's education department, with support from Steven Keating, energy manager, and Alison Willis, port health officer, from the county council.

Out-of-school-hours learning co-ordinator Alastair Birch said the event was very enjoyable and thanked the school staff and parents who supported the event.
