Prefabricated wall systems are becoming a popular element of building construction, lending themselves to streamlining construction schedules and reducing overall construction costs. They also offer the potential for increased quality due to assembly in controlled factory environments. This paper reviews basic principles and concepts for the design of waterproofing systems for prefabricated brick wall panels. Using a project case study, the author shows that failure to adhere to certain proven conventional practices can have serious adverse consequences.

Of the construction processes involved in high-rise building construction, core wall construction is a highly repetitive construction works. Therefore, the effective management of core wall construction works by a project manager can save costs and shorten the duration of high-rise building construction. This study analyzes a case in which a core structure succeeding method (CSSM) is applied to core wall construction. The results of the case study found that the efficiency of CSSM in terms of construction costs and duration is higher than that of the core wall preceding construction method (CWPCM).

The Cost

Completing project within cost is the target of most clients on any construction project. However, the achievement of this desire is just an imagination in the construction industry, because procurement and execution environments for projects are hostile and unpredictable. This study examines the determinants of building construction costs in South Africa and whether changes in the cost of certain resource factors such as construction equipment, labour and materials can be related to changes in building construction costs. The study employs a longitudinal cross-sectional quantitative research design approach and makes use of literature review and historical data obtained from institutional and governmental databases to identify the determinants. The data collected were analysed using time series analysis to confirm the trends in the cost of the resource factors and its alignment to the changes in building construction cost. After that, it makes use of an appropriate predictive modelling tool or causal analysis in establishing the determinants of construction cost. The results show that the price indices of construction equipment (EI), labour (LI) and materials (MI) have a gentler slope when compared with the Building Cost Index (BCI). It also emerged that later levels of the BCI are significantly and positively related to EI. The findings infer that the key determinant of increase in building construction costs in South Africa is equipment costs. Contractors and public or private sector clients in South Africa must utilize construction equipment optimally on projects, and these pieces of equipment should not be left idle on project sites or plant yards. Appropriate provisions should be made of equipment utilization policies which allow the joint ownership of equipment by contractors to mitigate the problems of cost increases. There are widely unexamined assumptions as to what resource factors are responsible for the growth in building construction costs in South Africa. Also is the similar high risk and uncertainty affecting the South African construction industry as a result of these fluctuations. The results of the study extend the knowledge of the resource factors responsible for building construction costs increases.

The article is concerned with the problem of cost estimation for multifunctional construction projects on the stage of pre-investment feasibility study. For addressing issues such as the definition of capital investment unto the property assets the author considers the procedure of construction cost estimation on the base of the cost indicators of room function groups. On a research basis the author has developed the calculation methodology of the cost indicators of room function groups. Room function groups present the assembly of spatially connected facilities and communication passages which are focused on define operations functions accomplishment. There is the procedure of the application of room function groups costs for the definition of the investment volume in building construction in the phase of poorly detailed preliminary design.

Building actors need accurate estimates in order to efficiently undertake the construction of buildings. The knowledge of real expected costs of construction works is a necessary condition for contractors to submit competitive tenders and for developers to be aware of the magnitude of their investment. In this paper, an innovative process-based model is presented, the POP model. This model aims at providing building actors with a systematized methodology to calculate building construction costs based on the planning, organization and scheduling of the expected works. Unlike the model of construction work units, the most widespread estimate model in Spain, the POP model comprises all construction costs in a direct way by identifying the production processes involved and the resources consumed, giving a new approach to the principles of the activity-based costing methodology in tune with the process-based cost models that are emerging in the international scene. Nowadays, the model is being applied in real construction works with satisfactory results of transparency, detail and adaptability. Not only reliable estimates are obtained, but also the performance of works is devised, allowing its optimization and control.

Major Consideration

The objective of this research is to quantitatively measure and compare the environmental load and construction cost of different structural frame types. Construction cost also accounts for the costs of CO2emissions of input materials. The choice of structural frame type is a major consideration in construction, as this element represents about 33% of total building construction costs. In this research, four constructed buildings were analyzed, with these having either reinforced concrete (RC) or steel (S) structures. An input-output framework analysis was used to measure energy consumption and CO2emissions of input materials for each structural frame type. In addition, the CO2emissions cost was measured using the trading price of CO2emissions on the International Commodity Exchange. This research revealed that both energy consumption and CO2emissions were, on average, 26% lower with the RC structure than with the S structure, and the construction costs (including the CO2emissions cost) of the RC structure were about 9.8% lower, compared to the S structure. This research provides insights through which the construction industry will be able to respond to the carbon market, which is expected to continue to grow in the future.

The Comparative Study

This paper presents an overview on the comparative study between the precast and conventional building construction methods for housing project in Sarawak. In this study, a residential building project with double-storey terrace houses was chosen for the comparative study as they have typical structural layout plans with minor variation. The same building was designed into both conventional and precast structural layout respectively in order to obtain direct comparison results. To ensure the results obtained are representative and unbiased, the structural components integrated in both construction methods are listed and each critical cost component, for instance the project direct and indirect costs were broken down further in order to evaluate the total building construction costs. From the research results, it can induce the relationship between the time and costs evaluation. The overall construction period for the conventional building construction method was 240 days while the precast building construction method was 82 days. As compared across the results for the project construction costs, it shows that precast construction method with RM 354,969.50 is more cost effective with about 19% less than the conventional building method with total amount of RM 422,687.85. The results reflect the significance on selection of the construction method, namely the precast building construction method not only can shorter the construction periods but also reduce the construction costs since it reduces greatly the expenses on the project direct costs particularly the machineries costs.
