“…Change of plan or scope of project is one of the most significant causes of variation in construction projects and is usually the result of insufficient planning at the project definition stage, or because of lack of involvement of the owner in the design phase (Arain et al, 2004). This cause of variations affects the project severely during the later phases.…”

“…Variations are inevitable in construction and are to be expected both at the design and construction stages (Akinsola et al, 1997). The needs of the client may change in the course of the design or construction stage and market conditions may impose changes to the parameters of the contract, and technological developments may alter the design and choice of the method of construction (Arain, et al, 2004).The review of design may bring about changes to optimize design, hence the operations of the project. Furthermore, errors or omissions in construction may also force a change.…”

“…The main objective of this study is to identify the major factors causing variation in building construction projects in Ghana, using an opinion survey and suggest possible ways of minimizing the impact of variations orders in building construction II. LITERATURE REVIEW Client, consultant, contractor and external factors are the main causes of variations (Arain, et al, 2004). There are many reasons that may cause the stakeholders to initiate variations during project administration.…”

“…The client spells out the needs and objectives of the projects, establishes the scope of works and the required quality standards (Arain, et al, 2004). During the construction stage, client initiates variation orders due to cost, aesthetic and other reasons through the consultant (Mohammad et al 2010).…”

Variation in construction means modification of design, changes in quality, quantity of work including the alteration of standard of materials or goods to be used in the work and the removal from site any kind of material not in accordance in the contract. In Ghana, Variation order has become major issue in the construction industry. This had resulted in cost overruns, delay and in some contracts dispute, between parties. The aim of this paper was to identify the root causes of variation; effects of variations on projects in Ghana and the means of reducing the impact of variation order. The method of the study involved literature review, primary data collection, interview and closed -ended-questionnaires. Mean Scores Method was used to rank the identified factors causing variation. Analysis Of Variance Test was use to test for the significant difference between means among the professional groups. The study revealed that most causes of variation were change of design by client and inadequate working details. Establishment of oversight project management committee and flow of information were identified as means of controlling variations during project administration.
