Determination Of Labour Output On Windows And Doors Fixing

Determination Of Labour Output On Windows And Doors Fixing

Abstract

A major element in the success of the construction assiduity is the delicacy in construction design estimates. former inquiries have shown that utmost of the affair constants used by estimators in the Nigerian construction assiduity are moreover deduced from experience or are remnants of British social heritage. Hence,non-uniform labors are extensively used. The exploration is aimed at using work study approach to empirically establish labour affair for doors and windows fixing in the Nigerian construction assiduity. A aggregate of 30 construction spots were observed, 15 each for Kano and Jigawa States for three sizes of doors and three sizes of windows. The data collected were anatomized using deducible statistical analysis. The results of the analysis carried out established general average affair values per day of;12.00 nr,13.00 nr and16.00 nr casement windows sizes 1500 x 1200 mm, 1200 x 1200 mm and 600 x 600 mm independently. While11.00 nr,10.00 nr and11.00 nr sword doors were established for sizes 1200 x 2100 mm, 900 x 2100 mm and 750 x 2100 mm independently. A two- tagged t- test analysis was used in assessing the influence of the labour productivity factors on the affair of the workers observed. The deducible analysis revealed that mode of employment and experience, significantly affected workers affair. Also the findings should serve as an effective birth for contractors to exploit the affair numbers uprooted according to productivity factors in order to optimize the productivity of their workers and profitability.

Background Of The Study

The effectiveness of the construction assiduity is heavily reliant on its position of productivity. As noted by Adnan et al( 2007), until the productivity position of construction conditioning is bettered, the nation’s frugality will continue to suffer lapses. Hence, perfecting productivity has come a major concern of every profit- acquainted organisation( Adnan et al,

). An important element of the construction assiduity productivity is labour. Labour costs represent a considerable proportion of the final cost of a structure, generally counting for between 40 to 60 of the structure cost( Butchan et al, 1993). In addition, labour is known to be the most important factor of product since it’s the only factor that creates value and sets the general position of productivity( Ameh and Odusami, 2002). According to Yates and Guhathakurta( 1993), labour productivity is the value of gross affair per worker, appertained to as man- hour or work- hour. It also could be appertained to as the careful attempts to measure the physical affair of labour taking into account the other factors that affect construction productivity.

Recognising its significance, several studies have concentrated on the factors that affect labour productivity( Oloko, 1983; Lema, 1995; Yagba and Ayandele, 1999; Ameh and Odusami, 2002; Adnan et al, 2007; Kane et al, 2007). still, none of these studies provides an empirical evaluation of the position and extent of influence of these factors on the productivity of the Nigerian construction labour. Given the significance of such an issue, this exploration seeks to examine the influence of some productivity factors on labour labors that were empirically established by the authors for some named trades, and published away.
