Cost Factors

Purpose This paper aims to identify the main non-cost factors affecting accurate estimation of life cycle cost (LCC) in building projects. Design/methodology/approach Ten factors affecting LCC in building project cost estimates are identified through literature and interviews. A questionnaire survey is conducted to rank these factors in order of priority and provide the views of cost practitioners about the significance of these factors in the accurate estimation of LCC. The data from 138 construction building projects completed in UK were collected and analysed via multiple regression to discover the relationship between capital and LCCs and between non-cost factors and cost estimation at each stage of the life cycle (capital, operation, maintenance and LCC). Findings The results of analysis of existing LCC data of completing project and survey data from cost professionals are mostly consistent with many literature views and provide a reasonable description of the non-cost factors affecting the accuracy of estimates. Originality/value The value of this study is in the method used, which involves analysis of existing life data and survey data from cost professionals. The results provide a plausible description of the non-cost factors affecting the accuracy of estimates.

Major Factors

 In this research, a model for estimating construction cost of villas is presented. The model takes into account four major factors affecting villa's cost, namely: built up area, number of toilets, number of bedrooms and the number of stories. A field survey was conducted to collect information required for such model using data collection form designed by the researchers. Information about 150 villas was collected from six well experienced consultants in the field of villa design and supervision in Oman. Collected data was analyzed to develop suggested model which consists of two main levels of estimate. The first level is at the conceptual design stage where the client presents his/her need of space and basic information about the available plot for construction. The second level of cost estimation is carried out after the preliminary design stage where the client has to decide on the finishes and type of structure. At the second level of estimation, the client should be able to decide whether to precede for construction or not, according to his/her budget. The model is general and can be used anywhere and was validated for accepted degree of confidence using the actual cost of the 112 executed villa projects in Oman. The villas included in this study were owned by clients from both high and low income brackets and had different types of finishing material. The developed equations showed good correlation between the selected variables and the actual cost with R2  = 0.79 in the case of conceptual estimate and R2  = 0.601 for preliminary estimate.

This chapter aims at examining two main aspects in security project: cost estimation and investment assessment. The characteristics of security projects are stressed on and the importance of adopting management task is determined. In addition, the chapter examines the different cost estimation models developed for security project and discusses the technical and managerial factors affecting the cost estimation and the management of project. In addition, a review of research works directed toward security investment models is determined. In fact, most models have focused on determining the optimal security investment allocation based on budgetary aspect, economic, and financial constraints. Recent models are interested to examine more specific security features when assessing the required investment (e.g. system vulnerabilities, attacks type, risk factors, data privacy, and insurance). finally, the chapter discusses future directions that could be investigated to make available useful models for cost estimation and investment on security projects.

The Cost

Time and cost are important factors affecting the successful completion of the construction building project. This study analyses and examines the cost and time comparison of precast and cast-in-situ slabs of a particular building. Taking into account that slab is one of the important structural members, this study will take the hollow core slab in particular which can define as precast prestressed concrete elements contain an empty void inside of it which mostly used for floor, roof slabs and wall panels. The results demonstrate that the precast slab construction time is extremely faster in comparison with the cast-in-situ slab as it took around 31 of working days and 43 days in total after considering the holidays while the precast slab took around 9 working days only and 13 days in total. The results also show that the cast-in-situ slab is inferior in both cost and time duration. As cast-in-situ cost is 3.76 times higher than the precast slab, and the time duration is 3.31 times longer.

Purpose Cost estimating process is an important element within the project life cycle. Comprehensive information, expanded knowledge, considerable expertise, and continuous improvement are needed to obtain accurate cost estimation. The purpose of this paper is to identify the critical factors that affect accuracy of cost estimation and evaluate the degree to which these factors are important from contractors’ and consultants’ viewpoints. Design/methodology/approach Qualitative and quantitative research approaches were adopted in collecting and analyzing the data, and testing the hypotheses. Based on the literature review, a questionnaire was prepared and then was modified according to the results of face-to-face open-ended interviews conducted with 11 project managers. The final version of the questionnaire was distributed to a random sample of 265 respondents. For analyzing the collected data Kendall’s and Mann-Whitney tests were conducted. Findings The analysis revealed that there is a strong agreement between contractors and consultants in the ranking of the factors related to consultant, contractor, design parameters, and information. A slightly weak agreement between contractors and consultants was noted regarding the factors related to market conditions (external factors) and factors related to project characteristics. Furthermore, the results show that the top ten factors affecting the accuracy of cost estimate are clear and detail drawings and specification, pricing experience of construction projects, perception of estimation importance, equipment (cost/availability/performance), project complexity, clear scope definition, accuracy and reliability of cost information, site constraints (access, storage, services), material availability, financial capabilities of the client, and availability of database of bids on similar project (historical data). Originality/value Offers an original view of the concept of accuracy of cost estimates as it relates to the efficiency of the project relying on both literature review and empirical evidence.

Assessment Results

The construction and built environment sector is dynamic. It is made up of professionals who are knowledgeable about design, planning, construction and cost estimation. Design is one of several courses undertaken by construction students. Assessing design drawings is demanding for tutors as the assessment criteria need careful consideration. Assessment results may encourage or discourage students. Their morale may be affected if they feel their efforts have not been rewarded. Achieving a balance between the tutors’ decisions and students’ satisfaction is therefore important. This research sought to identify factors affecting students’ satisfaction with grades in design courses. The study was undertaken among year 3 and 4 architecture students in a Nigerian university. One hundred and twenty students were invited to reply to an online questionnaire. Their responses revealed that most of them were not satisfied with their tutors. They felt that marking was inconsistent. This study identified a range of ways students felt assessment could be improved. Chief amongst these was a suggestion that the same tutors assessed the work of all students (rather than for several tutors to be involved). Based on these issues, the paper suggests ways to balance tutors’ assessments and students’ satisfaction.
