The Institute of Structural Engineers has produced the fourth edition of the Temporary and Demountable Structure Guide (TDS Guide).
The technical guidance is much the same, although they have relaxed the independent site checking requirements for fabric structures, no doubt following pressure from MUTA (trade association for marquees and tents). The non-technical sections have been updated and not surprisingly the CDM regulations are dealt with for the first time.
The TDS Guide should be in the library of every operations team that deals with complex and demountable structures. It can be purchased from the Institute of Structural Engineers at www.istructe.org.
