This project of 14 units is nestled in Nottinghamshire on the outskirts of Wollaton Park. The works included the demolition of existing dilapidated structures, together with associated infrastructure works.
Amongst the challenges, there was a sloping site which has lead to a difficult work environment that was overcome with engineering solutions and land reclamation work. SHG also had to manage the access to the site, which was via a lane with heavy traffic throughout most of the day, with the aim of minimalising impact on neighbouring residents. 
The scheme has been created in a luxury design with a great deal of attention being paid to the overall look and feel as well as a focus on the outside spaces and landscaping.
The 14 large properties have required extensive reinforced footings works, drainage and landscaping works. Our team has worked in this challenging environment to provide solutions to the client and deliver an astounding site.


Our client in Sheffield had been suffering with faulty storm drains and issues of standing water in their customer car and showroom car parks.
Following our initial survey it became apparent that the underground pipework had failed due to blockages and collapse and that the channel drainage systems were not routinely maintained.
We very quickly excavated a new trench and connected the channel drainage onto a new run and reconnected the storm manhole. The work was backfilled and compacted and reinstated swiftly to allow the car park to operate at full capacity by the end of the day.

On this site the drain exited 2.5m below the level of the adopted surface water drainage. We closed the road, and by using trench boxes we installed a new drain at 3.8m deep under the road and extended it by 60 meters at minimum fall until its level met up with the adopted system which we connected in. Three new concrete manholes were put in.

Section 106 and section 104 licenses were applied for. We had regular meetings and inspections from Severn Trent Water and Highways Agency. We used a rubber tracked machine, but afterwards we still had to plane the road off and relay the top coat. We gave pre-warning to all neighbours affected who temporarily lost access t o their properties. We even got a box of biscuits from one of the neighbours for the consideration we showed.

As part of the project the plots on site require the buildings to be positioned to fit in with the lie of the land. The sloping aspect of the site means that various retaining wall structures are required to be built to assist with level changes between properties. The walls we construct are either reinforced concrete walls or traditional brick and block built to a detailed specification relevant to the task it is performing.
All of our walls are protected to the rear face with a GeoDrain membrane which is fixed in place prior to reinstatement. A suitable perforated land drain pipe is then laid to the base at the rear of the wall and wrapped in a woven fabric geotextile terram membrane. The drain is surrounded with gravel before usual backfill reinstatement commences.
The woven fabric protection allows groundwater to free flow into the drain but prevents any silts and external ground material entering the drain and causing blockages. The drain is then laid into the local soakaways.
Providing a groundwater escape route is important as inadequate drainage can result in a build up of groundwater behind a retaining wall and this ‘trapped’ water exerts hydrostatic pressure which can affect the structural integrity of the wall.
our team then backfill in layers and compact as well as continuing the gravel margin up the back of the wall to maintain water flow to the drain.

As part of the groundworks on site our teams lay all services and/or ducting to the properties in preparation for live connection by the relevant bodies. We continuously liaise with the water, gas, electric and communications companies to ensure the infrastructure they require is properly laid and maintained until handover. We also ensure that any new information or requirements from them is adhered to on our sites, such as extra ducting, secondary routes or a change in service box types. When the teams arrive on site to do live connection we are on hand to assist with any cable pulling or rope pulling as required as conditions on site and needs on site can constantly change.
