Additional Details    

• The existing ground upon which the new extension had to be constructed was highly contaminated with tipped Gypsum which had to be removed and remediated.

• As a part of the project Hewlett were required to undertake the removal and remediation of 120,000m³ of tipped gypsum board plus 75,000m³ of bulk earthworks.

• The resited Gypsum material had to be relocated and re-profiled and was then covered with 48,000m² of Geosynthetic Bentonite material liner followed by a 300mm composite drainage layer and 500mm of topsoil and seeded to prevent leachate into local water courses.

• Hewlett carried out all of the Drainage, Excavation, Foundations, Floor Slabs and highway infrastructure to the development.

• Concrete works were completed to a high standard and all works were completed on time and within the original cost budget.
