Problem
Beforehand the site was an Iron Age settlement
Strategies
1. The site must be surveyed in order to do an archaeological investigation; field evaluation, remote sensing and full scale excavation. (English Heritage, 2011) 2. Inform the local archaeological officer of any kind of discovery; any finds are protected by the Archaeological Areas Act. (English Heritage, 2011)

Problem
Presence of high water table
Strategies
1. Installation of underground system of drainage pipe. The pipes can route the water away from the building into a storm collection system to an area that is free of accumulating water. (Illingworth, 2000) 2. Waterproofing the outside of the foundation with a vapour barrier of 4mil polyethylene film to control the rise of water vapour. (Illingworth, 2000) 3. Installation of wellpoints is inserted into the ground from which water is drawn from a vacuum generated by a dewatering pump to be discharged via a tank to a suitable point. (Project Dewatering Ltd, 2009) 4. The foundation design must be a suitable design for the clay soil to not be affected by groundwater e.g. pile foundation (Emmitt & Gorse, 2006)

Problem
A cross fall of 0.5m from south to north
Strategies
1. Fill one side of the cross fall with earth to bring it to level or dig out the other side down to level. Excavation must take place

Problem
Presence of asbestos and lead paint
Strategies
1. The asbestos samples must be removed by workers who are trained in asbestos removal and wear protective clothing and a respirator. (HSE, 2006) 2. The removal of asbestos must be carried out by a contractor licensed by the Health and Safety Executive, all asbestos containing material identified should be removed in accordance with The Control of Asbestos Regulation 2006. The asbestos waste must be disposed safely at a licensed disposal site. (HSE, 2006) 3. Demolition must take place after the asbestos and lead paint has been removed and the contractor must submit a Demolition Notification. (Northern Insulation Contractors, 2008)

Problem
High voltage of 11Kv crossing the site
Strategies
1. Consult the Local Planning Authorities on relocating high voltage cable somewhere out of site. (HSE, 2006) 2. The area where the passage of the plant is required under the voltage cable should be restricted to the minimum for the safe crossing of the plant. The safest way is for the passageway to cross the route of the cable at right angles. (HSE 1997) 3. Providing loading and unloading areas away from the high voltage cable so that there is less chance of contact. (HSE, 1997)

Problem
The surrounding area is residential; schools and nursery facilities and a small industrial area
Strategies
1. The perimeter must be hoarded and identified by suitable signs. (HSE, 2007) 2. Any access for pedestrians which leads onto a traffic route must be sufficiently separated from that traffic route to enable pedestrians to see any approachable vehicle or plant from a place of safety. (HSE, 2007) 3. Prevent people outside the boundary from being hurt by using scaffolding, particularly toe boards, brick guards and netting. (HSE, 2007) 4. Schedule working hours to adapt to school opening hours; when children are on their way to school and finish from school, construction work is stopped temporarily in order to ensure children’s safety. (HSE, 2007)

Problem
Presence of hydrocarbons in the soil
Strategies
1. To issue Remediation Notices under EPA (Environmental Protection Agency) to
