Curtis Bros. Construction used an anteroom during the build to allow all other medical facilities in the building to continue treating patients safely. Considered a vital tool for mitigating the spread of hospital-acquired infections (HAIs), anterooms help control the flow of contaminated air between the renovation site and sensitive, patient-occupied areas. Using Stark Systems Containment, we built a rigid wall structure from ceiling grid to floor and created an airtight seal to keep construction dust inside the construction area and outside this common hallway.
