Subcontractor submittal software helps specialty contractors build compliant submittal packages and verify that the equipment they're specifying meets the construction submittal requirements before submission. BuildSync works in two ways. First, it generates submittal packages for mechanical, plumbing and electrical equipment by pulling together the right project data and organizing it against spec requirements. Second, it reviews existing packages by extracting every technical characteristic from the submittal documents and comparing each one against the project specifications. You get a detailed compliance report showing what passes, what fails, and what needs clarification. The goal is straightforward: you catch the issues on your end before the GC or design team catches them on theirs.
