However, many architects will tell you that VE often results in \u2018engineering the value out of the project.\u2019 \u00a0VE is not a good way to make up for \u2018scope creep\u2019 (un-planned growth in a project\u2019s scope), or to correct for inaccurate (as opposed to imprecise) earlier cost estimates.<\/p>\n","protected":false},"excerpt":{"rendered":"
