45 Fremont has a riser system for telecommunication needs which runs from the main point of entry (MPOE) in the basement through telephone and equipment closets located on each floor. For security purposes, these doors are locked at all times. In order to maintain the integrity of the building infrastructure, Shorenstein Realty Services has contracted with Montgomery Technologies to oversee all work in the telephone closets. Montgomery Technologies will only grant access to these closets upon approval. Please contact Montgomery Technologies at 1-866-824-8362 to obtain a work order. Once the Building Office receives a work order from Montgomery Technologies, you or your vendor may enter the approved closet(s) after signing in with Security and providing valid identification.
