Abstract
There is dearth of information on output level of building operatives in Nigeria,
consequently, the output constants currently used for preparation of construction estimates
are remnants of British colonial heritage or derived from untested experiences. Therefore
this study aims at empirically determining output constants for floor finishes (screeds and
tiles) for building project in Abuja. The objectives are to identify the productivity factors
related to Building Engineering Standard Method of Measurement 3 (BESMM3) and
evaluation of their impact on the outputs of five work items of floor finishes. The
procedure adopted field survey involving work measurement to observe and measure
operatives output. Data was collected from 80 on-going construction sites with an average
of 50 gangs of workers for each work item to establish the following average outputs per
day; 25mm thick cement and sand screed (23.70), 44mm thick cement and sand screed
(19.31), 400 X 400mm ceramic floor tile (27.38), 300 X 600mm ceramic floor tile (30.18)
and 300 X 300mm ceramic floor tile (23.61). The study also revealed a significant
difference on mode of employment and period of observation on the outputs of the
workers. The results suggest that experience and negotiation as mode of employment affect
output of workers to varying degrees based on the thickness of floor screed and unit area of
floor tile. The study has recommended that the established output should serve as an
effective baseline for efficient estimating process and be in compliance with the BESMM
requirements.
