| dc.description.abstract | This study presents the experience on the effect of cost escalation of two - lane paved road project executed by TANROADS which is under the Ministry of Works in Tanzania. The research aimed at assessing the factors that contribute to cost escalation and recommending desirable solutions. The study used multiple methodologies including in-depth interviews, documentations review and analysis so as to identify factors for cost escalation in Tanzania. During this study, 21 persons from the construction authoritative Institutions were interviewed. The respondents included engineers, quantity surveyors, architects and institution heads from MOW, TANROADS, ERB, AQRB, CRB, NCC, TACECA and ACET. The research findings revealed the four priority factors causing cost escalation include: price increase of materials, equipments and labourers; late payments caused by inadequate allocation of budgets funds; high dependency to foreign contractors and consultants in design, execution, and supervision; and inadequate capacity of implementing Agency for cost control during planning, design, and implementation of the road projects. Other factors include: inadequate availability of construction equipment, materials, and skilled labourers in the locality; currency devaluations; and long procurement process and award of the contract of the procurement entity. The overall conclusion is that the Ministry of Works and TANROADS lack effective tool and code of practice for establishing and controlling unit rate for paved road projects in Tanzania. It is recommended that a code of practice should be developed to be used as a guiding tool and cost control during planning and implementation of roads project. The code of practice should explain the different methods and approaches on how to prepare and control the cost of paved roads projects in Tanzania. In order to implement the code of practice, it is recommended that TANROADS and MOW establish an appropriate guidance including software for the purpose. The software should be based on the actual cost based method. It is also recommended to increase the capacity of implementing agency, local contactors and consultants for effective planning, execution and supervision of the paved road project. | en_US |
