Brisbane City Council Reference Specifications for Civil Engineering Work S150 Roadworks – Annexure

COMMENTARY USING THE DOCUMENTS The latest edition of this annexure can be obtained by down loading from the Brisbane City Council internet site (www.brisbane.qld.gov.au) via the following path: Planning and building › Planning guidelines › Subdivision and Development Guidelines › Annexures to reference specifications for Civil Engineering work. The user can either mark up a paper copy to suit the proposed contract or edit the file direct in Microsoft Word 2010 (or later). Please note that the section and page breaks in the Microsoft Word file have been inserted to suit double-sided printing. This annexure forms part of a two-part specification system. The corresponding reference specification and this annexure must be incorporated in the tender documents either by reference alone (quoting an edition date) or both by reference and physical inclusion. The annexure modifies the reference specification by additions, deletions or amendments and takes precedence over any inconsistent provisions in the reference specification. In particular, the annexure adapts the reference specification to the technical needs for the particular project. However the user may, alternatively, employ a ‘Job Specification’ to convey job-specific information. If both annexure and job specification are used, the job specification takes precedence. Because of the job-specific nature of the annexure, it is important to identify the project adequately in the header to the annexure or in the text of each section (either by description or by a contract serial number). CONTRACTUAL PROVISIONS The reference specification and annexure deal only with technical and administrative matters. They do not deal with commercial arrangements. It is most important that they are used in conjunction with an adequate contract, which makes all necessary commercial arrangements including provisions for measurement of work and methods of payment.
