1. A circular dated 25 Jan 2013 was issued by SCDF on the permissible variations for technical requirements for precast household shelter designs. SCDF and BCA have gathered feedback from the building industry and made amendments to the precast household shelter technical requirements for greater clarity and design flexibility.
2. The amendments to the technical requirements include a common modular increase in the length and width of the precast HS; dimensions between the core and the nearest fixtures; details of closed link at the starter bar level for the cast in-situ joint between two HS; shear key design on HS for precast plank or cast in-situ slab construction and the details of tapered hollow cores for ease of production; etc. The key amendments are summarised in Annex A . The amended technical requirements for design and construction of the precast hollow core household shelters are attached in Annex B for easy reference
3. The amended technical requirements shall take immediate effect. Please convey the contents of this circular to members of your Institution/Association/ Board. The circular is also available in CORENET-e-Info: http://www.corenet.gov.sg/einfo any inquiry or clarification, please contact the undersigned at 68481478.
