Question

who are the people that will benefit in the study of research topic "Impact of Variation Order in Construction Projects?"

Answer 1

First let's understand what variation order (VO) is:
Variation order is the deviation experienced in any project from base contract or work scope mutually agreed at contracting time. It is written agreement between the contracting parties that represent an addition, deletion, or revision to the contract documents, identifies the change in price and time and describes the nature of the work involved. Variation orders arise for a variety of causes, of which some causes are foreseeable and others are not

Now to understand who are the people that will benefit in study of "impact of VO in construction projects" We need to have look on causes of VO and it's remedial measures

Causes

1. Change of Schedule:

A change of schedule during the project construction phase may result in major reallocation of resources. A change in schedule means that the contractor will either be required to provide additional resources or keep some resources idle. In
both cases, additional cost is incurred & if we avoid this cause contractor is going to save lot of money which would otherwise had incurred during the process.

2. Poor Workmanship:

Defective workmanship may lead to demolition and rework in construction projects.This results in delay and increased cost.so if we are able to avoid this cause we can save this additional cost. Hence contactor as well as public will surely get its benefits.

3. Change in specification by the consultant: Changes
in specification are observed frequently in construction
projects (O’Brien, 1998). Changes in specification
results in variations to the project, leading to delay and
increased overall cost.

4.Quality of projects:Variations affect the quality of work adversely.The quality of work is frequently affected by frequent variations because contractors have to compensate for the losses by cutting corners.

Conclusion: Most significant causes are unavailability of
equipment, poor workmanship, design complexity,
change of schedule and impediment to prompt
decision making process.
• Logistic delays, delay in completion and increase
project cost are significant effects of variations
faced in construction projects.

More research on causes of VO in construction projects means saving lot of extra money by contractors as well as owners.
