EXP COVID-19 Offices White Paper

Solutions to effectively combat covid-19 in offices

1. Introduction

Executive Summary The Center for Disease Control and Prevention (CDC) has identified controlling risk as a critical factor in infection control. (1) It includes a multilevel systems approach, with consideration to complex variations in transmission, and the interconnection between people, their environment, efficiency and the need for purposeful redundancy.

This white paper provides a review of possible approaches and technologies that may help reduce transmission risk of the coronavirus disease (COVID-19) in office environments. The information included in this white paper was prepared by industry experts at the global engineering, architecture, design and consulting firm, EXP. The combined and collective expertise of our multidisciplinary engineers, our science + technology experts, our gaming experts, our hospitality experts, our health care experts and other supporting expertise provides insight into delivering effective solutions to the commercial office industry. The purpose of this white paper is to provide information about potential conventional and innovative methodologies to minimize the transmission of COVID-19. It is not intended to be a scientific brief; therefore, references are provided at the end, along with a list of EXP experts who provided information and oversight to the paper. As multidisciplinary professionals and concerned members within our communities, we are committed to helping others develop a better understanding of the steps that can be taken to better protect our employees, clients and building visitors. The recommended preventative treatments outlined here-in are ones we consider to be the most effective, at this time, to reduce and/or stop the spread of COVID-19 in offices.

1. Directly via large droplets (i. e., emitted when sneezing or coughing or talking) 2. Indirectly via surface contact when those large droplets fall out of the air and land on surfaces (i.e., hand-hand, hand-surface, etc.) 3. Transmission through small droplets that remain suspending in the air for hours (i.e., aerosolized virus) 4. Fecal-oral transmission route (i.e., water closet flushing) To effectively reduce the risk of transmission, several measures for each path must be put in place. An effective plan should include purposeful redundancy based on the level of risk. Fortunately, measures will reduce the risk associated with all the possible paths. For example, if a significant number of infected individuals are not permitted to enter a property, the risks for all paths are reduced. These strategies would include staff surveys, staff temperature checks and even guest temperature checks.
