Basement – Excavation
Excavation of the site commenced, the excavated chalk was used as fill material for the construction and improvement of farm roads in the locality, avoiding expensive transport and tipping costs and minimising environmental impact.
This picture shows the steelwork for the reinforced concrete strip foundations and the various stages of constructing the reinforced concrete slab; blinding with sand, waterproof membrane, concrete and in the distance the steel reinforcing for the slab.
The foundation slab is complete and the extension to the slab to form the plant room on the lower floor is being constructed.
The blockwork and reinforcing for the walls to the ground floor store are rising quickly (08/08/2000)
The timber subframes are in position for the doors from the reception area to the conservation workshop and special store (18/08/2000)
Construction of the workshop floor
Concrete is poured to fill the cavity between the the blockwork. This method of construction with an inner and outer skin of blockwork with steel reinforcing and poured concrete in the cavity is designed to provide a simple to build structure capable of withstanding the loads from the building and the soil backfill which will surround most of the building. This method avoids the need for expensive shuttering and provides a fair face for the internal walls. The blocks were sourced locally.
The pads for the floor beams are cast with shuttering.
The GLULAM beams forming the first floor are positioned and joined and protected from the elements
Packs of pre machined timbers for the floor are delivered and laying commenced at the beginning of the month.
Insulation and Backfilling to Ground Floor
An adhesive is applied to the external blockwork, FOAMGLAS insulation panels are then fixed to this surface. Where the wall is to be backfilled, (to reduce temperature fluctuations in the store area) a waterproof membrane is applied. Where the surfaces are exposed they will be rendered.
