               2.1   INTRODUCTION                                                                    2.4   APPLICABLE CODES
                     Structural guidelines listed below shall be applied to all building structures and    The following codes with listed parameters shall be permitted for the purpose of
                     are intended to provide minimum structural design requirements for building           structural design. Technical codes not listed in this document shall be submitted
                     sub and super structures. Please refer to the applicable codes for detailed           for review and approval prior to adopting in the design. Consultant should ensure
                     technical guidance and requirements.                                                  that selected design standards are the latest editions and fully compatible with

                     The guidelines are aimed to give the design engineers a general idea of the           circulars.
                     basic requirements in designing the structures to comply with the CED-Trakhees
                     regulations and the relevant building codes. It is anticipated that the use of       2.4.1   DEAD AND LIVE LOADS
                     these guidelines will result in a uniform design and construction of buildings
                     throughout projects in CED-Trakhees jurisdiction.                                          1.   BS 6399: Part 1 ‘Loading For Buildings: Code of Practice for Dead
