The project requires demolition of three existing exterior metal stair sets with porch roofs, followed by design, fabrication, and installation of replacement sets at the US Naval Research Laboratory (NRL), Building A59. A mandatory site visit is scheduled for Wednesday, September 9, at 10:00am EDT at NRL, with visitors required to notify NRL Contracts at least two days in advance. Alternative visit dates may be requested but are not guaranteed, and failure to attend does not extend the response deadline. Performance will occur at NRL, Building A59.
