A further way in which we can demonstrate the flexibility of Beamform is in its utilisation to form toe beams at a raft edge.

The pictures below show a semi detached house plot on a major UK house builders’ site. The house builder was concerned with the program delays and waste being generated by using traditional methods of construction (strip/bent mesh, ‘Z’ bars, straight rebar and standard sheets of mesh). This particular house type required 4-5 days to complete, allowing concrete to cure between 2 pours, with materials costing £562 (6 uses allowed on timber formwork) and labour costing £606 (Total cost of £1168).

The ROMTECH solution was to re-design the house type to incorporate prefabricated toe beam cages, Beamform permanent formwork and mesh manufactured to suit the house type as an improved method of construction. Approval was given on the re-design by both the Structural Engineer and the NHBC. The material cost for these components was £771 and these were installed in 1 day at a labour cost of £230 (Total cost of £1001).

Since there were 150 houses on this site to complete, with varying house types, it soon became apparent to the house builder that our method was the way forward. This was proved by the fact that the savings on this house type alone, due to the change in the method of construction, meant that the remaining plots of this type (21No), were in effect FREE OF CHARGE.

The effect on programme, (4 plots of this type prepared Monday to Thursday and all poured Friday), meant that the following trades were not competing for space, plant or other machinery.

The financial savings to the house builder relating to finance and interest charges were such that this is now their preferred method of construction.

The differences between the two forms of construction can clearly be seen from the photographs below. These show how modern methods of construction in conjunction with Value Engineering, off-site Prefabrication, Best Practice and ROMTECH Groundworks’ experience can clearly demonstrate that the cheapest price is not always the best value.
