Abstract. This paper recommends an aid to control discrepancies between drawings and documents in a project. The synchronisation may assist to better project's preparation and documentations. The causes of discrepancies that found out during the contract stage may lead to ineffectiveness of construction cost. The controlling process initiated from the tendering stage as to minimize the causal by any of the consultants which some items may left behind or possibly not describe fully without the thorough affiliation of coordination. The method to reduce discrepancies between drawings and documents is identified through Case Study based on 'hands on' project. The case study is focused on the preparation of architectural detailing. Therefore, the relationship of 2-Dimensional (2-D) Tender Drawings and bills of quantities is compared with the Elements of Building Works by Malaysian Standard Method of Measurement of Building Works Second Edition (SMM). The relationship study will simplify and supersede any unnecessary detailing. Thus, the application of the synchronisation method will result effectiveness of documentation during the contract stage by reducing discrepancies.
