Chamber systems aid £47m campus works

PRECAST drainage and stormwater chamber systems from FP McCann have been installed at the new Aberdeen Academy.

Balfour Beatty has started construction of the £47 million facility, which will cater for up to 1,350 students when it is completed later this year.

Alongside learning provision, the three-storey building will also feature a games hall, fitness suite, six-lane swimming pool, gardens and a 3G all-weather pitch.

Aberdeen City Council appointed its development partner, hub North Scotland, last summer and Balfour Beatty successfully tendered for the main construction works.

Preparatory infrastructure and drainage works are well underway, with FP McCann revealing the firm is playing a major role by supplying the precast concrete drainage and stormwater chamber systems to Aberdeen-based civil engineer, David Smith Contractors, who is undertaking the main infrastructure works on behalf of Balfour Beatty.

Two DN2100 large catch pit units are being utilised in the drainage system, along with smaller DN1200 catch pits, DN1200 and DN1500 Easi-Base units, associated manhole rings, and a number of pre-fitted hydro-valve flow control chambers.

Manufactured at the company’s Knockloughrim plant in Northern Ireland, the units have each been supplied with a DN1050 rocker pipe for installation on site and come complete with integral safety ladder.

FP McCann described the one-piece sealed sump units as being “easy to install on a granular bed”, minimising the amount of time required below ground level. Inlet points are cored at the factory to allow for “simple” pipe connection.

Commenting on FP McCann’s proprietary chamber systems on the Aberdeen campus, Peter Carson of David Smith Contractors said, “Using these one piece pre-benched, channelled and cored precast units significantly increases productivity.

“They almost eliminate the requirement for wet trades such as ready mixed concrete and mortar, which, during winter working, is a real bonus.

“Additionally, the speed and ease of installation reduces the amount of time operatives need to spend below ground, which is a big health and safety benefit.”
