A Systematic Review of The Causes and Effects of Variation Orders in Sustainable Construction in Developing Countries
Variation orders are a frequent occurrence in construction. It is inevitable, but it can be controlled to minimise the cost, time overrun, and enhance the quality of work. This systemic review compiles more than 80 articles of various constructions between period of 2009 to 2022, with a focus on the...

Variation orders are a frequent occurrence in construction. It is inevitable, but it can be controlled to minimise the cost, time overrun, and enhance the quality of work. This systemic review compiles more than 80 articles of various constructions between period of 2009 to 2022, with a focus on the similarities and differences in variation orders between developing and developed countries’ insight towards sustainable construction projects. A review of the existing literature identified that the common cause of variation order from twelve countries is the owner originated variations, change in design by consultant, error and omission in design, and lack of coordination between consultant and contractor. Out of the listed thirty causes of variation order the effects lead to affected work progress, increase in project cost, and delay in payment. The developing countries face different challenges due to economic and political instability and lack of resources, skills and experience. Even though the unbalance ratio between stakeholders could bring biased to overall findings, this review provides useful directions to construction professionals and policymakers.
