“…This means that the respondents are familiar with cast in situ and pre cast/ prefabrication method while in the case of semi precast method, they are not familiar with the method. The findings correspond with Idrus andNewman, (2002) andSeeley, (1995) in terms of their classification of solid slab construction. They classified solid slab construction in majorly cast in situ and precast while semi precast was out of their classifications.…”

The choice of construction method employed for constructing suspended slabs in buildings tend to impact significantly on the delivery time of building project. Thus, this study aims at assessing the impact of various construction methods on duration for constructing hollow and solid floor slabs in buildings in Lagos State, Nigeria. The research design for this study was a survey design approach and the populations of the study were professionals involved in construction projects; Architects, Civil Engineers, Builders, Quantity Surveyors, Building Services Consultant and Contractors. These are the major participants in the construction industry in Lagos State, Nigeria. The analysis is based on 46 (forty-six) returned questionnaires out of the 60 (Sixty) questionnaires administered. The data from the questionnaires were analyzed using descriptive statistics tools such as frequency, percentage mean ranking while the hypothesis were tested with a paired sample t-test tool. It was found that the systems or methods of slab construction well known to the respondents are cast in situ, precast and semi-precast. The Cast in-situ beam and slab construction ranked as the most frequently adopted method followed by flat slab, hollow clay pot and waffle slab construction. In terms of construction time, placing reinforcement and construction of formwork takes more time than other processes in solid slab construction while in construction of reinforced cast in situ concrete hollow slab; formwork construction, placing hollow bricks or blocks or moulds on formwork and curing concrete takes more time than the other processes involved.

“…One is explained in the important research of Warszawski [14], who found six main criteria: architectural design, physical performance, technology, management, economics, and marketing. Other researchers have also reported criteria for selecting building systems for such things as concrete floors [15], roofs [16], industrialized housing [17,18], and building automation [19].…”

This research deals with a technique to expedite group decision making during the selection of technical solutions for value management process. Selection of a solution from a set of alternatives is facilitated by evaluating using multicriteria decision making techniques. During the process, every possible solution is rated on criteria of function and cost. Function deals more with quality than with quantity, and cost can be calculated based on the theoretical time value of money. Decision-making techniques based on satisfying games are applied to determine the relative function and cost of solutions and hence their relative value. The functions were determined by function analysis system technique. Analytical hierarchy process was applied to decision making and life-cycle cost analysis were used to calculate cost. Cooperative decision making was shown to consist of identifying agreement options, analyzing, and forming coalitions. The objective was attained using the satisfying game model as a basis for two main preferences. The model will improve the value of decision regarding design. It further emphasizes the importance of performance evaluation in the design process and value analysis. The result of the implementation, when applied to the selection of a building wall system, demonstrates a process of selecting the most valuable technical solution as the best-fit option for all decision makers. This work is relevant to group decision making and negotiation, as it aims to provide a framework to support negotiation in design activity. AbstrakKeputusan Kelompok dan Koalisi pada Manajemen Nilai. Penelitian ini berkaitan dengan penyusunan model untuk mempercepat pengambilan keputusan kelompok selama pemilihan solusi teknis dan membangun sistem alternatif untuk proses manajemen nilai. Pemilihan solusi dari serangkaian alternatif dilakukan menggunakan teknik pengambilan keputusan multikriteria dengan kriteria fungsi dan biaya. Proses hirarki analitis diterapkan untuk pengambilan keputusan, dan analisis fungsi serta analisis biaya siklus hidup digunakan untuk menentukan nilai bagi solusi terbaik. Pengambilan keputusan kelompok disusun secara kooperatif melalui identifikasi pilihan, analisis, dan pembentukan koalisi. Model ini akan meningkatkan nilai keputusan pada proses desain. Hasil pelaksanaan, yang diterapkan pada pemilihan sistem dinding bangunan, menunjukkan proses pemilihan solusi teknis sebagai pilihan terbaik untuk semua pengambil keputusan. Riset ini relevan dengan pengambilan keputusan kelompok dan negosiasi, karena bertujuan menyediakan kerangka kerja untuk mendukung negosiasi dalam kegiatan desain
