As with any business organization in a competitive market, the financial viability depends on the ability to maximize its returns at minimum costs. The problem of minimizing the total costs on transmission lines wayleave maintenance or bush clearing is one of minimizing the costs on labour,...

Land use planning in Zambia is currently riddled with the problems of being cumbersome, unsatisfactory, unbalanced and fragmented. The study revealed that the above scenario, may be attributed to among other reasons, the inappropriate and often out dated land use planning process tools currently...

In Zambia, sanitation options are still few and inadequate to effectively serve the urban poor in peri-urban settlements. Continued growth of the settlement now calls for alternatives to pit latrines, which have become difficult to manage given the increasing population. Sanitation is poor hence;...

Unethical practices are prevalent in the construction industry. Bid rigging, corruption,fraud, collusion, coercion, price differentiation, tampering with claims and payments certificates, conflict of interest, embezzlement and tender manipulation have been reported in construction literature...

Disputes in the construction industry are often inevitable. Disputes arise from the interpretation and application of any part of ambiguous, unplanned and conflicting contract documents. There are many methods which can be used to resolve disputes. The study in this dissertation examined the...

The construction industry plays a central role in the creation of any nation’s wealth. For developing economies, it forms the backbone of most industries. Cost escalation, schedule overruns and quality shortfalls in construction projects often offset the intended contribution of the industry to...

All sheet metal forming processes occur after permanent plastic deformation resulting in the material properties changing and therefore it is necessary to determine the extent to which a material can further be deformed for subsequent forming operations. Traditionally, experimental trial and...

This research work was to provide a locally produced electric motor to drive the UNZA pump.The work was carried out by using the UNZA pump parameters and electric motor material from published works on the electric motor design and manufacture and real experience from examining electric motors in...

A first-order, consecutive, two-stage reaction model for the reduction of cr2o3 from slag was developed. The model was applied to the results obtained by studying the effect of various parameters on the rate of reduction of cr2o3 from a CaO-SiO2-Al2o3 slag, by carbon dissolved in molten iron, at...
