In response to the COVID-19 pandemic, Gordian is adding new Biohazard Remediation and Infectious Disease Precaution line item costs and modifiers to the 2021 RSMeans data update. The new modifiers allow cost estimators to adjust to the specific precautions for each project. Performing daily temperature checks, donning & doffing PPE, washing hands or disinfecting tools and equipment all impact labor efficiency. These modifiers provide a mechanism for cost estimators to allow for those inefficiencies in their project cost estimates.

Biohazard Remediation line items include the installation of temporary barriers for alternate traffic flow, ensuring social distancing or employee/customer checks and tests.

Infectious Disease Precautions modifiers include adjustments to labor costs that allow the estimator to choose which precautions are required.
