In order to calculate time savings, a survey was sent to the team asking, “About how many hours per week does PlanGrid save you, compared to using paper blueprints?” Five project managers and four superintendents responded to the survey, all reporting weekly time savings of at least five hours. The project management team reported, on average, 8.1 hours saved per week, per person, and the superintendents reported 6.63 hours per week, per person. Together, the nine responding team members reported a savings of 67 hours per week or 3,484 hours annually. Incorporating the national average salary, the total annual time savings is $194,056. Time savings from the 20 other members on the project is not reflected in this total savings.

Bartlett Cocke General Contractors reported an internal budget of $13,500 for paper blueprints. They also reported an average of $1,000 - $1,500 budgeted by each of their subcontractors. For the purpose of this calculation, we’ll use an average of the reported budget which is $1,250/subcontractor. We estimate about 20 major trades on a given project* which nets $25,000 total budget for all subcontractors. Therefore, the total paper budget including the general contractor is $38,500.

Rework is one of the most expensive disruptions to a construction project and can be one of the hardest construction costs to measure. Yet, the negative impact rework has on the construction schedule and budget is something that cannot be ignored. One of the main reasons for rework is the field worker’s accidental usage and building off of outdated drawings. This is due to the difficulty of physically distributing continually changing drawing sheets and updating them with the most current information. Using PlanGrid’s complete platform, automatic syncing, distribution, and versioning of new sheets eliminates this problem.
