Project Overview

Project Location Location Map Aerial image of the site

This Old St. Louis Courthouse is located in downtown St. Louis, Missouri, near the riverfront on a city block bordered by Fourth, Chestnut, Market and Broadway Streets. The Courthouse is situated on the St. Louis Arch Grounds and has served as the center for political and social activity in the mid-19th century St Louis. The building and grounds provided a public forum for gatherings and political speeches while the courtrooms hosted significant trials in American history such as the Dred Scott civil rights case and the Virginia Minor women’s right to vote case.

The old courthouse is a Greek Revival Architectural style with a cruciform plan and a central rotunda. Construction began in 1839 and completed by 1845, however the current extant dome of a Renaissance style, was replaced in 1851. The Old Courthouse is essentially a 2-story building, with the north wing being the only portion that has a third story and features formal Greek Revival style elements with pedimented facades, fluted Doric columns, pilasters and elevated entrances which are all representative details of that style. The central Rotunda rises to 5 levels before tapering to an oculus at the center. The building initially evolved over a period of 36 years from a federal style courthouse that was eventually enclosed and then expanded into the Greek Revival structure that stands today.

Developmental History

Original Federal Style Courthouse 1828 Construction of the Old Courthouse 1838–1862 Ongoing Courthouse Use 1862–1895 Decline of the Old Courthouse 1895–1935 National Park Establishment 1935–1940 Rehabilitation of the Old Courthouse 1940–1965 Maintenance and Management 1965 to Present Exterior and First Floor Accessibility Improvements 2014-2019

This slide shows the development history. The Jefferson National Expansion Memorial was designated by President Franklin Delano Roosevelt in 1935 in an executive order but the Old Courthouse was officially deeded over to NPS in 1940. More information in available in the Historic Structures Report of 2013.

The Old Courthouse is significant for both its architecture and its association with historic events.

Resources for Project Information:

Technical Plans + Specifications, July 2022* Interior Wayfinding and Signage, July 2022* Historic Preservation Plan Matrix, August 2022* pending Historic Structure Report, July 2013* General Management Plan, 2009 Secretary of the Interior’s Standards for Historic Preservation NPS Preservation Briefs Supplemental Studies* *Included in solicitation Resources

There are several resources available online on our NPS websites as well as in the solicitation package that will aid in a better understanding of this very complicated building. With the evolution of construction, each wing was developed slightly differently with different construction methods. The resources that are available online are the park’s General Management Plan, developed in 2009 that provides high level planning for the overall park, The Secretery of Interior Standards for Historic Preservation governs all of the NPS existing buildings and landscape capital improvements projects, and

Refer to the solicitation package of technical plans and specifications, including the appendices – these documents will prepare you for understanding not only the technical aspects of the project but also the importance of the historic fabric that we’re going to be working with and around. There is a Historic Preservation Plan Matrix that will aid in your understanding of how the technical plans and specifications will impact some of the character-defining features of the building – the matrix document references the developmental history, NPS historic preservation policies, Secretary of Interior Standards for Historic Preservation and assists in identifying areas warranting historic fabric protection, the document will be issued in an upcoming amendment.

Note that included in the solicitation package - there are hazardous material reports, interior wayfinding and signage drawing set, the historic structure report that provides background on history and significance and General Hierarchy of Decisions and Protections in understanding how the design was developed to minimize impacts to the historic fabric. Also note that with any excavations in and around historic buildings and cultural landscapes, archaeology is a consideration and so there will be archaeological monitoring provided by the NPS as the projects moves forward with any excavation, digging, ground disturbance. That coordination is very important to NPS.

Existing Conditions

This is a site plan of the Old Courthouse, designed as Greek cross with 4 wings that can be quite disorienting when you are in the building.

Basement

Here is the basement floor with some images of the significant interior rooms on the left but also storage and maintenance spaces on the left. The basement floor plan is segmented so there is not contiguous access from one wing to another wing – you will have to go up to the first floor in order to access another basement wing. And you can see the central Rotunda basement structure. Please note that all of these floor plans are from the Historic Structures Report and NOT from the technical drawings. These are somewhat simplified and intended to highlight some of the significant features of each floor and to orient you without the detail of the Construction Drawings.

Basement

These are more photos of the basement, note the varying conditions of the interior of the basement level. The brick barrel vaulting is one of the many important features of the basement level.

First Floor

Here is the first floor with several images of character defining features such as the flooring materials, casework surrounding the doors, iron work on the staircases and the Rotunda. There are various limestone flooring and encaustic tiles.

First Floor

Here you see some exhibit spaces in the galleries on the first floor and in the Rotunda and also accessibility improvements, completed within the last 10 years. These are temporary or semi-permanent accessibility improvements, that were carefully installed to facilitate accessibility and to protect the historic flooring falling in line with the Secretary of the Interior Standards for Historic Preservation.

Second Floor

Here is the second floor, that features some of the courtroom spaces that have undergone some restoration over the years. One of the things to highlight aside from the historic elements and materials, is that there are varying finished floor elevations throughout this project, reflecting back on how each wing was constructed differently and at different times. Providing for accessibility is a big component of this project.

Second Floor

This is the area surrounding the dome/Rotunda as well as a photo of one of the historic courtroom spaces.

Third Floor/Attic

Here is the third floor and attic spaces, note the skylights and how there are few rooms in the eaves of certain wings, there is also access into the Dome itself. These are spaces that we are unlikely to go into on the tour.

Third Floor/Attic

Some images of the Dome structure.

Project Background – Significant Features Interior character-defining features include:

Limestone slab floors (corridors, rotunda) Cut and polished stone tile checkerboard floors executed in black and white, and red and white squares.

Encaustic tile floor in the Southwest Courtroom/Gallery Decorative balconies and columns in the Rotunda, and early tapered tongue and groove wood strip flooring on the second, third and fourth levels, dated as early as 1869.

Two restored circular/oval courtrooms on the second floor with c. 1870 (possible 1905 remodeling) courtroom furniture, surrounded by wood and cast-iron columns.

Here are some of the interior character defining features that are very important to preserve throughout this project – to protect during construction and to minimize the impact on where the project scope will work directly with the historic fabric – this is noted in the Historic Preservation Plan Matrix and in the Historic Structures Report. Note the various floorings, decorative balconies and columns and courtrooms spaces.

Project Background – Significant Features Wooden casework for door surrounds and many original doors; most of the original window casework was removed in 1910-1912, so the remaining nine windows retaining their original casework are extremely important to the building.

Casework in the building copies Grecian motifs and is executed not only in wood but in stone and cast iron in various locations within the structure.

Here is the casework surrounding the doors – some out of wood but there are casework constructed from stone or cast iron.

Project Background – Existing Conditions Basement Special Considerations:

Protection of Historic Fabric Hazardous Materials Segmented Access Downtown St. Louis Location

Here are some of the existing conditions that we have noted – read it all. Note that there are hazardous material reports and work plan in the solicitation package.

Project Scope of Work – Overview Fire Suppression Installation of a building-wide fire suppression and alarm system;

Heat and Cooling Removal of the 1941 National Park Service era steam heating system with later installed window air conditioning units and the introduction of a four-pipe hot and cold-water modern heating and air conditioning system and installation of an upgraded electrical system to support these changes;

Window Replacement Replacement of 140 sets of 1942-54 era 6 over 6 window sash for ventilation; bid option Accessibility Accessibility upgrades including three accessible toilet rooms and interior elevator;

And here are critical building systems – fire suppression, HVAC, electrical and plumbing as well as window replacement and accessibility improvements.

Fire Suppression Building-wide fire suppression and alarm system

This will be a more general, high level discussion on the scope of work – a building-wide fire suppression and alarm system.

Heating and Cooling Radiator removal 4-pipe hot and cold-water modern heating and air conditioning system Commissioning

Also, the HVAC system – removal of existing steam heating system and radiators and the installation of a new four-pipe hot and cold water heating and AC system. And there is also commissioning. Many of the routing for the project will go through existing openings or chases in order to minimize impacts to the historic fabric – there is the document in the appendices, General Hierarchy of Decisions and Protections that list out the decision making process during design.

Window Replacement Ventilation Eliminate window units

Window replacement – removal of bird netting, window units due to the new AC system being installed, etc. Part of effort for this project is to restore the historic facades for this highly visible building.

Accessibility Accessible Restrooms Elevator to 2nd Floor Ramps (multiple finished floor elevations) Rotunda Railing

Accessibility – the installation of an elevator to provide access to the second floor, as well as ramps that address the various finished floor elevations and accessible restrooms. There is also a new rotunda railing included in this project scope.

Here is the first floor plan – you can see the highlighted yellow portion indicates that existing concrete floor was a non-historic 1940s concrete replacement work and therefore became the strategy for how to design for an elevator in the historic building.

Exterior

Exterior Scope:

Ameren Vault + Duct Bank Construction Trailer Chiller Courtyard

Some of the exterior improvements include the Ameren Vault and Duct Bank which will actually be constructed by Ameren but the coordination and acquisition is part of this project scope. There is also a chiller courtyard where work will occur. And that concludes my segment, back to you Tim/CO.
