There exists increasing competition in the construction industry, forcing contractors to be more cautious in calculating the mark-up for a project. For most contracts, the percent-markup is limited up to a certain range. In a tight bidding environment, the general tendency is even to "underestimate a project". In such cases, the profit will be even...
