Sažetak

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. The study’s major recommendation
is that, adequate and careful analysis should be conducted before taking a decision on the choice of floor system been adopted for any project.
