1900 Lawrence Smoke Control System Rational Analysis

The 1900 Lawrence project will add a new 30-story high-rise to the Denver skyline. It will be the tallest office tower to be built in downtown Denver in more than 40 years. When the building is completed in 2024, it will include state-of-the-art office space, expansive ceiling heights with floor-to-ceiling glass, multiple floors with private tenant terraces, and unparalleled views of the Front Range, Coors Field, LoDo, and Skyline Park.

The design includes three elevator hoistways and three smokeproof exit enclosures requiring smoke control system pressurization. Due to the building height, the city of Denver required an engineering analysis of the smoke control system design. Coffman performed the CONTAM modeling of the building and prepared the stairwell and hoistway pressurization smoke control system rational analysis report. Coffman worked with the project design team to develop a solution to overcome the challenges of having multiple hoistways and stairwells opening into common lobbies.
