• All cages are labelled for ease of identification, and are supplied with a layout drawing for accuracy and speed of placement. Splice bars are loose-tied inside the relevant cage
• Prefabrication offers a reduction in the need for skilled labour, which can lead to a reduction in programme, a reduction in waste caused by unforced errors, and an improvement in site Health and Safety.
• A key benefit of ROMTECH prefabrication is that semi - skilled site operatives are able to install cages in a few hours rather than the normal 1-2 days of the loose rebar option.
• Deliveries can be phased to an agreed programme: this being particularly useful in tight or restricted sites. Colour coded labels can be factory fitted for easy site identification of delivered components.

Using customer’s General Arrangement (GA) and Reinforced Concrete (RC) drawings and schedules, we identify the opportunities for rebar prefabrication where appropriate. By liaising with The Engineer, we are able to provide alternative solutions which offer commercial cogency in terms of programme and site productivity. In addition, fewer prefabricated components of known weight & size, mean fewer, better organised site operations, leading to significant benefits in site Health and Safety.

Such objectives are achieved for groundbeams by detailing for maximum prefab cage length with a minimum of loose rebar cage to cage connections. The provision of factory welded skid spacers provides soffit support to beam cages off the blinding and avoids the site fitting of separate spacer units. The colour coding of prefab beam elements, as depicted on the ROMTECH layout plan, offers the possibility of rapid, accurate site - installation. In addition, the LOLER - compliant cage offload system allows the consignment to be removed without the need to climb onto the vehicle deck.

ROMTECH Shear Ladders avoid the usual ‘sausage link’ detail which requires loose rebar upper and lower reinforcement layers in two way spanning suspended slabs. This product therefore permits the use of heavy prefabricated mesh layers above and below while furnishing both an adequate punching shear resistance in the finished slab and an effective means of spacing upper and lower mesh around the column head.

In the case of retaining walls and suspended slabs, ROMTECH can offer the options of various bar diameters and centres, staggered bar locations and ‘flying ends’ within its individual prefabricated mesh or mattress units. The main site benefits of these features are a reduced site installation period, an alleviation of congestion at laps and a reduction of the ‘working at height’ element.
