Project Management System

The international experience of integrating building information modeling (BIM) into project management system with innovation implementation accent has been revealed in this article. The events carried out on federal and regional levels concerning the President of Russia directive on building construction industry modernization and construction objects transferring to life cycle management by means of BIM were analyzed. The large company experience of implementing BIM was summarized with describing some examples in different cities and regions of our country and thus the main directions of this technology development were determined. The key points of BIM and project management system pairing and impacting an innovation choice witch determine the project economic efficiency in the integrated management system were shown. The main reports of "Building construction projects technology and management: new practices and prospects" conference by Moscow Trade and Commerce Chamber were reviewed in this direction and problems of the new investment and construction project management technology implementation were shown. The ways to solve these problems were disclosed by work examples of PAO "Sberbank", and successfully working in our country firms Bilfinger Tebodin - BIM design and Beiten Burkhard -jurisdiction support. Some economic efficiency questions of BIM implementation were disclosed in the report delivered by The Plekhanov University of Economics (project and program management base department of Capital Group). Management system suggestions, regarding BIM implementation in Moscow construction were given.

Flexural Tests

The present paper of a series deals with the experimental characterisation of flexural toughness properties of structural concrete containing different volume of hooked-end steel fibre reinforcement (75 kg/m3, 150 kg/m3). Third-point flexural tests were carried out on steel fibre reinforced concrete beams having a cross-section of 80 mm × 85 mm with the span of 765 mm, hence the shear span to depth ratio was 3. Beams were sawn out of steel fibre reinforced slab elements (see Part I) in order to take into consideration the introduced privilege fibre orientation (I and II) and the position of the beam (Ba-a, Ba-b, Ba-c) before sawing (see Part I). Flexural toughness properties were determined considering different standard specifications, namely the method of the ASTM (American Standards for Testing Materials), the process of the JSCE (Japan Society of Civil Engineering), and the final proposal of Banthia and Trottier for the post cracking strength. Consequently, behaviour of steel fibre reinforced concrete was examined in bending taking into consideration different experimental parameters such as fibre content, concrete mix proportions, fibre orientation, positions of test specimens in the formwork, while experimental constants were the size of specimens, the type of fibre used and the test set-up and test arrangement.
