Residual Material

In the implementation of a building construction project, it cannot be avoided the emergence of the remaining construction material or called construction waste. The rest of the material is something that is of the nature more than what is required either in the form of work or construction material that is left / scattered / damaged so that it cannot be used again according to its function. The amount of residual material can be minimized by exploring the factors that cause the residual material to occur and the use of a good management system. The more residual material found on the project, it can be interpreted that the smaller the profit from implementing the project.

Forward Linkage

The factors used to calculate the Forward Linkage, Backward Linkage and Real Benefit are the Total Environmental Costs. The highest total environmental cost was Iron and Steel that needs to be resolved immediately because it uses natural resources over the carrying capacity, higher environmental cost than standard, and contributes low real benefit. Iron and Steel, secondary steel products and non-residential building construction need to be monitored closely because they are able to link to other production sectors more than other production sectors, and they have high environmental cost. To design the sustainable development strategy of the country, therefore, need to use the information in this research to support the decision.

The moisture in building construction material affects the physical properties of buildings and he may lead to their degradation. With few exceptions, building materials are almost never dry. For the expected negative effect of moisture on building materials of structures is needed accurate method of determining the characteristics of their moisture as possible. The capillary conductivity coefficient characterizes transfer of liquid moisture in porous material. The method for its determination is experimentally arranged in such a way that it is possible to apply diffusion equation derived from the Luikov equation that is a phenomenological description of liquid moisture transport in porous materials as well as from the continuity equation, which expresses the classic conservation of matter principle. To records of the moisture distribution has been developed the methodology for measuring of moisture in the porous material, using microwave radiation. The calculation of the capillary conductivity coefficient and its dependence is based on the moisture curves in 3 D in non-stationary state of wetting, determined by non-destructive method.

Efficiency And Productivity

It is now well-established that the industry faced enormous challenges. To overcome these challenges and hence improve efficiency and productivity requires a deeper understanding of the challenges. In this chapter, the main challenges related to construction material and equipment, man-power and management will be examined. The consequences of these challenges which often lead cost overruns and delays will be discussed. The aim of this chapter is to provide a deeper understanding of these challenges so as to inform the choice of the decision support systems to be used in the subsequent chapters.

Construction industry is seen to be able to play a bigger role into a sustainable society by offering sustainable construction. As the premier construction material across the world, concrete has a major determining role on the effects, good or bad, of construction on the environment, meanwhile the formwork system is one of the important construction methods in building construction, which eventually will lead to more sustainable construction. In this context, this study focuses on the importance of the formwork system and its influence on achieving sustainable construction. The study aims to identify the basic sustainability objectives that considered responsive to formwork system. Using questionnaire survey distributed among construction experts, the economic category had been selected as the most important factor that considered respond to the formwork system, and the environmental category comes second while social comes the third. Furthermore, fifty percent of the respondents agree that type of formwork system effect on the sustainability of the construction project and about forty percent was moderate about it. Determination the objectives of sustainability that respond to the formwork system, which covers all activities and processes related to the formwork system can assist developers and others stakeholders to evaluate the performance of the system in order to make enhancement to the system.

A building construction project cannot be completed successfully by only planning and scheduling. Project controlling that consists of project monitoring and updating, is the other critical stage. Construction materials cost and quality are becoming a severe problem in Ethiopia, especially in Ambo Town, where little consideration is given. The study tried to evaluate different factors affecting the materials cost and quality on building construction site, rank significant factors that are prevalently affecting the cost and quality of materials used for building projects from the point of view of the respondents, and established a model to optimize materials cost and materials quality using multilinear regression method to come up with the model best fit. Purposive sampling was used, and 180 questionnaires were administered on building construction firms to analyze Material cost Optimization and quality control Improvement- Case Study of Ambo Town. To achieve this, a questionnaire survey containing factors affecting Building construction material cost and quality, which were identified by literature and Interview, was analyzed by using the Relative Importance Index, Pearson's correlation, and Multilinear regression model. Variables are statistically significant at 95% confidence level is assessed that all of the independent variables are positively related to Building Construction material cost and quality. The RII results showed that Material Wastage minimization (RII = 0.908), Proper workmanship (RII= 0.859), Sufficient Training of workers/staff (RII = 0.876), Proper forecasting of materials price in the market (RII = 0.850), Using suitable, safe and secure storage (RII = 0.886), Quality checking for each delivery of the aggregates to the site (RII = 0.889), Cutting of materials ( glass, tiles, plywood) (RII = 0.870) and Design changes (RII = 0.770) were ranked as the most significant among factors affecting building construction materials. Also, Two Multiple linear regression models were established for both dependent variables (material cost and material quality). The analysis results showed all independent variables were significant and had a strong positive relationship with dependent variables. The values of R2 for the developed equations indicated 0.771 for material cost and 0.777 for material quality. Hence, the basic recommendations such as planning and monitoring construction activities and inspection and verification of materials were anticipated to be exercised by key role players of the construction industry.

Abstract The aim of this paper is to analyse the completeness of data contained in the register of real estate prices and values. Transactions concerning parcels with residential buildings located on them were studied. On the basis of, among others, data obtained from this register, real estate valuers evaluate real estate. The following market characteristics were selected for the analysis: transaction price, usable area, year of building construction, construction material of building walls, number of storeys, plot size, and others. The data were obtained from the District Office in Koszalin. The study was conducted on the example of Koszalin district in the years 2010‒2016. The technique of quantitative and qualitative analysis of documents was used in the study.
