Station Platform Rehabilitation Program Contract 3, WMATA, Washington, DC

Mimar provided architectural and engineering services for the renovation of all public and staff restrooms for the Blueline and Greenline Train Stations as well as Wayfinding. There were (6) stations to be renovated; (4) of the (6) stations (the Greenline Stations), required wayfinding signage design. The program for this project was provided by the owner. A set of parameters and the owners project supervisor’s standards had to be met. The construction document standards ranged from the text style, the layers, the pen weights, and no variables were excepted. If there were any deviations required during the construction document process, due to existing conditions, these items were resolved between our office and the Prime Contractor.

For the above-mentioned project, Mimar focused mainly on the existing restroom renovations scope, primarily to meet the ADA code compliance. However, we also performed a variety of Technical and Programing resources during design, Project Management, as well as Wayfinding.

As for Construction Administration, we have a veteran staff of Project managers. We assisted the contractor throughout the construction phases of the building, providing constructability and guidelines, along with the coordination involving team members from other offices. After the construction of the project, we then provided as-built plans. Mimar was able to produce these documents, because of our firms Computer Aided System. As-builts can be developed incorporating each client’s set of standards, such as; format, CTB, and the layering set of parameters.

The scope of design services consisted of Wayfinding and the renovation of all public and staff restrooms. Wayfinding involved coordination with the lead Architect, Engineers as well as to perform a QA/QC evaluation of the final wayfinding submittal. Also, the Wayfinding scope included the verification of the proper signage locations and that the owner signage standards were met.

The renovation of the restrooms included a numerous number of components. The most significant component was to meet the current ADA set of guidelines. The ADA and code compliance checks were performed to ensure all applicable design criteria were met. This first involved a very detailed a descriptive evaluation of the current conditions along with a report that listed the deficiencies. To meet the ADA guidelines, the plans required the elimination of fixtures due to the fact that if the fixture count remained the same the clearances could not be met.

A very strict set of parameters and tasks had to be completed prior to each submission. The owner already had in place a set of dates to review the documents, respond to the comments, review the responses and backcheck the documents before each submittal.

The project work included:

1.            Survey and documentation of existing site.

2.            ADA evaluation Report for the Restrooms. 

3.            A separate ADA report was requested to evaluate the entrances from the main corridors and hallways.

4.            New Architectural Floor Plans

5.            New Reflected Ceiling Plans

6.            Toilet Accessories Schedule and a recommend list of Manufacturers.

7.            Photometric Report

This renovation also required the upgrading of all the Electrical and Plumbing Services and fixtures. Electrical and Plumbing Plans, both demolition and new, were provided. Again, as previously mentioned, the client had a set of standards that needed to be incorporated in our redesign. This was achieved by field verification and modifications to incorporate existing services. However, most of the current locations of each device, such as; Heaters, Hand dryers, electrical outlets, etc., had to be relocated. The existing exhaust system remained but required new fans and ductwork in some locations. Mini-Split, wall hung Heating Systems were installed in each toilet room. The entire project also required a complete redesign of the lighting lay-out along with a photometric report and the utilization LED lighting.  Also include was the coordination of Life Safety Fire Alarm System and Strobe devices along with sprinkler heads in those facilities that were fully sprinklered. Fully sprinklering all the stations was not part of the scope.
