AECO stakeholders, including designers, owners, and general contractors, don't have a benchmark method for them to perceive their own execution and know how to renovate themselves. A cloud-based BIM performance benchmarking application, BIM Cloud Score (BIMCS), has been offered to collect BIM execution (performance) data from BIM users over the nation in order to permit them to match their BIM performance with the effects gathered from their industry peers. This research aims to improve and authenticate a preliminary list of metrics that are appropriate for the proposed BIM benchmarking application. A survey was operated in the AECO industry and involved BIM architects (authors) and contractors (users) to authenticate the offered preliminary list of metrics. The replies from the survey were utilized for initializing the metric weights for the benchmarking method. In addition, an investigation of the differences in opinion between different groups of respondents indicated that out of 26 variables used, the perceived significance of 6 variables was statistically various between BIM authors and BIM users. This outcome shows that the surveyed architects and contractors were in contract with the significance level for most of the variables offered including model economy, model usefulness, and model productivity. Future adjustments of the metric weights might be required in the application based on the different intended purposes for the BIM models."

The fly ash generation is expected to grow further as coal would continue to remain major source of energy at least for next 25 years. The fly ash which is a resource material, if not manage well, may pose environmental challenges. At the same time worldwide agricultural footprint is fast growing, with vast agricultural land cultivation and active expansion of the agrobased industries. The resulting large quantities of agricultural wastes, unfortunately, are not always well managed or utilized. These wastes can be recycled, such as by retrieving fibres from disposed leaves and fruits bunches, and then incorporate in brick making. The natural fibres were sourced from coconut fibre, human hair fibre, pineapple fibre, oil pam fibre added within the range. This review describes change in the physical properties such as weight, density etc. and mechanical properties like compressive strength of fly ash bricks and clay bricks made by adding different natural fibres.

This method was developed by Dr. Thomas L. Saaty in 1970s as a tool to help with solving technical and managerial problems. During the past decade, the construction industry in India witnessed remarkable growth, in which the readymixed concrete (RMC) industry can claim to be a proud partner. Historically speaking, India missed the benefits of RMC technology for decades. It was only in the early nineties that the industry was born, but really commenced from the second half of the nineties. During the past few years, housing and infrastructure have remained the major expansion area. Faster speed and improved quality of concrete have been the two major demands of these sectors. Ready-mixed concrete was the right solution for this and it was heartening to see that the RMC industry responded positively to these demands. The result was the rapid growth of the RMC industry. The industry, which was initially confined to metropolitan cities, later spread to the two-tier and three-tier cities, vindicating the fact that RMC was a right solution for different markets. The growth of the RMC industry brought in its wake certain challenges, chief amongst which was about the quality of concrete supplied by RMC plants.

Concrete is the most widely used composite construction material. Ready mixed concrete can enhance the speed of construction and improve the quality of concrete components. The enormous advances in concrete technology now make it possible to obtain Ready Mixed Concrete with high strengths. The constituent materials of Ready Mixed Concrete (RMC), especially the fine aggregate, play a very important role for imparting better properties of concrete in its fresh and hardened state. Quality of construction is the most important aspect under consideration in the construction sector. Factory manufactured items always play a vital role in the quality of products. Ready Mixed Concrete is a major part of any concrete construction project. It is a convenient and efficient tool for building. The concrete is delivered to the site mixed and ready to be cast which saves time and money.

The utilization of Pozzocrete (P40, P60 and P100) as cement replacement material in mortar or as additive in cement introduces many benefits from economical, technical and environmental points of view. This paper presents the results of the cement mortar of mix proportion 1:3 in which cement is partially replaced with Pozzocrete (P40, P60 and P100) as 0%, 10%, 30% and 50% by weight of cement. Four set of mixture proportions were made. First were control mix (without Pozzocrete (P40, P60 and P100) with regional fine aggregate (sand)) and the other mixes contained Pozzocrete (P40, P60 and P100) obtained from DIRK India Private Limited, nashik, Maharashtra state. The compressive strength has been obtained with partial replacement of Pozzocrete (P40, P60 and P100) with cement. Test results indicate the decreases in the strength properties of mortar with Pozzocrete (P40, P60 and P100) for early strength at 7 days as partial replacement with the cement in the cement mortar 1:3. So it can be used in non-structural elements with the low range compressive strength where early strength is not required and low cost temporary structure is prepared.

By using high quality fly ash constituents, increase drastically the initial cost of concrete. The objectives of this research work were to intend to study the possibility of producing low cost concrete. To verify the impact of carbon content on fly ash on the strength and durability of concrete. For this purpose it was decided to enhance the 'as received' fly ash by eliminating particles coarser than 75μm, thus reducing the carbon content by 50%. It was also observed that the carbon content did have little impact on the strength and durability of concrete. Applications of fly ash, which is technically, sound, environmentally safe for sustainable development. Use of fly ash in various engineering applications can solve the problem of disposal of fly ash and other purposes. The major constituents of most of the fly ashes are Silica (SiO2), alumina (Al2O3), ferric oxide (Fe2O3) and calcium oxide (CaO). The other minor constituent of the fly ash are MgO, Na2O, K2O, SO3, MnO, TiO2 and unburnt carbon. This paper is study on low quality fly ash as an opportunity for sustainable and economical concrete for a new millennium.

The design mix proportion used were Conventional Concrete, 10%, 20%, 30%, 40% replacement of cement by industrial waste like fly ash and hypo sludge.In the test performed,the optimum compressive stress obtained by utilizing paper waste was at 30% replacement. At the place where strength is not of more importance or rather structure is for temporary basis then design mix proportion up to 40% replacement can also be utilized.Test also point towards developing low cost concrete by varying design mix proportion from 10%replacement to 40%replacement. The compared values of cost show gradual decrement in total cost of per cubic meter concrete. The difference in costfrom normal concrete to partially replaced concrete is about Rs.850/-.When government implement the projects for temporary shelters for who those affected by natural disaster, this material can be used for economic feasibility.To investigate the utilization of Hypo Sludge and fly ash as Supplementary Cementitious Materials (SCM) and influence of these hypo sludge and fly ash on the Strength of concretes made with different Cement replacement levels and compare with ordinary concrete. Investigate low cost concrete by using hypo sludge and fly ash as SCM and compare the cost of each per meter cube.

The safe disposal of this fly ash is the major environmental and socioeconomic problem. Conventional method of Rigid Pavement construction requires various natural resources like metal stone, sand, murum, cement, etc. and hence causes ecological degradation and imbalance. The cement is a costly ingredient in such construction. The use of fly ash in rigid pavement construction as cement replacement by 10-30% will save such resources and hence reduces the resultant concrete without any loss in strength. So, use of fly ash in concrete solves the disposal problem and automatically reduces the construction cost. If fly ash is utilized on large scale for rigid pavement construction, harmonized environment and sustainable ecology and economic development of the road infrastructure, can be possible.

A multi-facetted research approach was adopted. Initially, a literature review on materials management process in the construction project was conducted. This was followed by case studies involving four construction projects in order to investigate current practice in materials management to establish key problem areas and elements of good practice. The case studies also explored the requirements for integrating materials management and resource modelling in project management systems. The case study findings underpinned by literature results were used to develop a real-time framework for integrating RFID-based materials tracking and resource modelling.
It is concluded that the framework developed in this thesis can improve materials management on construction projects, particularly with regard to material tracking and integrating materials utilisation with the resource modelling subsystem in project management applications. Adoption of the approaches suggested in the thesis will enable the construction industry to improve the real time management of materials on sites, and hence improve project performance.
