Application of Genetic Algorithm in Resource Leveling and Allocation
Abstract: Resource leveling and allocation is one of the most important aspects in construction management. Critical path method and program evaluation review technique is frequently used for scheduling of construction projects. However, it is not capable of minimizing unwanted fluctuations in resource utilization profile. The basic idea of resource leveling is to minimize resource fluctuation. In addition to this, the paper uses the resource utilization period. This research paper presents an …

Behavioral Assesment of Nanoinsertions in Cement Mortar
Abstract: In this paper is reported a comparative behavior of the 28days and long-term mechanical strength of nano additions to cement mortars w.r.t. ordinary controlled cement mortars. Nanomaterials are constantly being used to upgrade everyday products which are in constant use by us. It is seen that when these materials are singly added in optimized proportions to cement mortar they enable an enhancement of compressive strength at 28 days and also …

Analysis of Highrise Building Using Diaphragm in STAAD Pro at Different Zones
Abstract: Each multi-story building means a significant investment and as such multi-story building analysis is generally performed using more sophisticated techniques and procedure. Therefore, accepting modern ways to seismic analysis of multi-story buildings can be very valuable to structural engineers and researchers. Floor and roof systems act as a diaphragm to transfer the lateral load to the vertical load supporting elements like beams, columns, walls, etc. For simplicity in the dynamic …

Behavior of Concrete Masonry Blocks with Ceramic Waste
Abstract: The blooming economic growth of India has led to development of construction sector. This has helped in increasing requirement of natural resources in construction sector and also leading to generation of large quantity of waste. Utilization of construction and demolition waste has become essential considering the problems such as disposal and health hazard of mankind. This paper mainly presents on ceramic waste which is a construction and demolition waste. Ceramic …

Change Order Management in Construction Projects: A Review
Abstract: The construction work is a difficult one and is associated with different changes. These changes generally lead to issuance of various orders. Classifying the reason of change order is critical in order to keep away from possible changes in further project. Decisions are taken every day in construction processes based on information available (which is most of the time incomplete), assumptions and the personal knowledge of the construction professionals. Hence, …

Effect of Size of Crushed Ceramic Tiles as Fine Aggregates in Cement Composites
Abstract: Recent studies have shown marked upsurge of waste production where ceramic contributes to 30% waste production in ceramic industry. Research on ceramic waste as partial substitute for fine aggregate has not been fully exploited. A focused investigation is made to check whether the ceramic waste having particle size same and lesser than fine aggregates as partial substitute in cement mortar and concrete. Ceramic waste collected is crushed into required sizes …

Papercrete: An Efficient Use of Waste Paper
Abstract: These days CO2 emission from construction sites because of cement use is a global issue. In order to address environmental effects associated with cement manufacturing and constantly depleting natural resources, there is a need to develop alternative binders to make concrete industry sustainable. On the other hand, more waste paper ends up in landfills or dump sites than those recycled due to which all countries are facing a serious challenge …

Cost Escalation, Schedule Overruns and Quality Shortfalls on Construction Projects
Abstract: Despite being a subject of discussion for over four decades, cost escalation and schedule overruns in quality shortfalls still persists as a challenge for construction projects. The present study was carried out to identify and rank the causal factors of cost escalation, schedule overrun and quality shortfalls in construction projects. Likert scale (range 1–4) was used for the ranking the causal factors.Keywords: cost escalation, construction, causal factors, shortfalls

Corrosion Behavior of Steel in Reinforced Concrete
Abstract: There are many environments where steel is exposed to different types of cement as well as different water cement ration along with variable PH of water mixed during the preparation of concrete. Deterioration of steel in such environment causes corrosion and its rate depend upon the type of cement and type of environment because it not only corrode steel but also affect the concreting material as it contains various chemical …

Impact of Change Orders on Construction Project Performance
Abstract: The success of any construction project depends on its timely completion, according to the specifications and within the budget. Change orders during the execution of the project are inevitable. Effective management of change orders is a key for the success of the project. In the present study, an attempt has been made to analyze the impact of change orders on construction projects performance. A questionnaire was designed to obtain the …
