The complexity of chimney design and manufacture today takes the industry beyond tradition by demanding an informed combination of technology and science. When applied to the ever increasing stringency of environmental influence and legislation this, to a greater extent, governs the parameters of performance.
Computer Aided Design procedures to BS4076 and CICIND Model Codes are applied to the development of all steel chimney types including: self supporting, guy supported, single flue, multiflue, insulated and clad, twin skin, refractory lined, lattice tower and flues, new flues to existing chimneys and advice on chimney height requirements.
A full drafting service utilising Autocad techniques provide general arrangement and detail drawings supplied either as prints or on disk. On contract completion, Rafferty’s further provides full documentation for future reference including: design calculations, as-built drawings, material test certificates, copies of inspection/Q.A Sheets, weld tests (where applicable), and C.O.S.H.H details.
