Richard H. Driehaus Museum
40 East Erie Street, Chicago, IL

The Driehaus Museum is housed in the Gilded Age home of banker Samuel Mayo Nickerson (1830-1914). The 25,000-square-foot mansion, built from 1879 to 1883, was one of the grandest residences of nineteenth century Chicago. Between 2003 and 2008, a meticulous restoration transformed the building into the Richard H. Driehaus Museum. Today, the Driehaus Museum preserves and interprets the home in order to promote the understanding and appreciation of historic architecture and design. The Richard H. Driehaus Museum and O’Brien Metal, Inc. collaborated to reproduce three new 7-ft-tall approximately 500-lb cast urns and pedestals as part of the Garden Entrance Restoration.

The Challenge

Due to the large size and intricate detail required to reproduce the original urns and bases, we were faced with complex challenges including a few highlighted below:

Logistics. Transporting 7-ft 500-lb cast urns to and from the museum to our Lincoln Park location. We worked closely with Amy Van Alst (Driehaus Museum) and Roger Machin (Methods & Materials) to ensure great care was taken in handling the urns and pedestals.
Casting size. Limitations of the sand casting process required that we split the urn casts into six separate casts in order to fully weld them back together during the fabrication process.
Extensive chasing. A requirement to accentuate the meticulous details of their counterparts.

The Process

Wax on. To begin fabrication, our Creative Team used a rubber mixture to apply multiple coats over the original cast iron urn.

Mother mold construction. Piece by piece, plaster was applied onto the dried rubber in order to create the mother mold. A mother mold is the shell that supports the flexible rubber mold helping it to retain its shape during the casting process. Clay (shown in grey) was used as dividers to split each plaster application into sections.

Shims and sections of mother mold construction

Plaster was applied, dried and repeated until every section of the urn had its own mold.

Mother mold reconstruction. The plaster pieces were put back together and prepared for casting the pattern in plaster.

Pattern making. After the rubber mold is placed inside the mother mold, plaster is poured inside to create the pattern.

Breaking the mold pt. II. Once the plaster pattern hardened, the rubber was peeled off to reveal a detailed surface.

Sand casting prep. Plaster pattern elements are ready for sand casting at the foundry.

After sand casting at the foundry, the aluminum alloy castings were brought back to our shop for extensive chasing, cleaning and welding by our Technology Team. The surface was detailed, primed and finally, faux-painted in a marble finish.

Final product. The cast urns as seen in front of the Driehaus Museum in downtown Chicago.

A similar reproduction process for the urns was used in creating the pedestals.

The Result

Presently, the faux-painted urns and pedestals can be seen welcoming visitors through the museum’s East Erie garden entrance in downtown Chicago.

The Charles Deering Library Restoration Project

Wed, 30 Jan 2013 11:47:00 -0500

Introduction

HBRA Architects and O’Brien Metal, Inc. collaborated on a project for one of the country’s most prestigious universities. Northwestern University needed to restore the famous Charles Deering Library’s West Entrance to its striking historic condition and add period pieces that uphold the collegiate Gothic style architecture. The goal was to create bronze castings and authentic steel forgings inspired by legendary blacksmith Samuel Yellin’s notable work in the 1930’s.

The Challenge

Vitrines are a glass-paneled case for displaying museum quality artifacts. O’Brien Metal, Inc. created four custom-made vitrine stands in which Northwestern University’s valued collections are displayed. Such collection includes the scribbled lyrics to “Eleanor Rigby” by John Lennon of The Beatles. The vitrine stands are hand-forged antiqued iron with authentic blacksmithing techniques throughout—hammered, contoured, specifically darkened and antiqued.

Large historic lamp posts serve as companion pieces to the Gothic façade of the library. The four posts were custom cast and fabricated in bronze with a statuary brown patina and are situated at the entrance of the Charles Deering Library.

The double bar exterior bronze handrails have a smooth finish, designed meticulously to create a contrasting element to the deliberately aged lamp posts. The hand rails are extruded bronze darkened and scuffed back to show the luster of the bronze. Its round rivets and legs have the same chamfered edge on the vitrine stands located inside the library.

A hand-forged way finding sign system made of iron in natural finish was also designed to match the existing workmanship of the Charles Deering Library interior. Twenty-nine variations of the signs—some hanging, wall-mounted, free standing or with backlit translucent glass to highlight the graphics in which the signs are intended for.

The Results

All components of the project were custom fabricated—either in bronze or steel—designed especially to match the historic metalwork of Samuel Yellin. It was important to maintain the integrity, tradition and history of the Deering Library’s Gothic architecture. O’Brien Metal, Inc. worked closely with Northwestern University, HBRA Architects and WB Olson, Inc. for six consecutive months to complete the restoration project in time for the reopening of the West Entrance Lobby to the Main Library in October 2012. The finished work can be seen at 1937 Sheridan Road at Northwestern University in Evanston, IL.

About Charles Deering Library

The Charles Deering Library was built in emulation of King’s College Chapel in Cambridge that opened in January 1933 and designed by James Gamble Rogers. Set on higher ground overlooking Deering Meadow, it is recognized today as the university’s most prominent landmark. (Northwestern Library History) The Library’s gates, lighting fixtures, grilles, railings, doors, and ironworks were by the legendary Samuel Yellin who was America’s master iron craftsman of the twentieth century. Yellin’s work often emphasized traditional styles but he still molded those styles to the needs of the clients and to his own ideas regarding craft. (NYC Architecture)

No Shape Is Too Complex: Recreating An Intricate and Historic Design Element

Tue, 27 Mar 2012 13:55:00 -0400

Situation

For a project at one of Chicago’s most prestigious buildings, Eric J. Smith Architect of New York City needed to replicate highly ornate cast iron balcony railings—a defining feature of the century-old residence’s unique aesthetic. Originally designed by Benjamin Marshall in 1911, the historic property is a crown jewel of the affluent Gold Coast neighborhood. Its existing railings accentuate the surrounding terra cotta surfaces and underline picturesque vistas of Lake Michigan and Lincoln Park. The new railings had to match every meticulous detail of their counterparts. To achieve this goal, Eric J. Smith partnered with O’Brien Metal and coordinated a unique design solution.

Goals

Replicate the style, intricate details, and nuances of the existing historic railings.
Develop a creative molding process for use on-site to capture and preserve the railings’ unique details and patterns.
Enhance the railings with new design elements: precision-machined, solid aluminum posts; highly secure, stainless steel mounting inlays to ensure safety; and updated spacing to bring the railing up to current code.
Integrate the new railings into a pristine built environment.

Results

Close collaboration led by Eric J. Smith Architects ensured clear project goals for aesthetics, function, and constructability. A series of mock-ups established the most efficient method of crafting the railings, capturing the intricate details, and blending them with the built environment.
Along with precise architectural detailing, the guideline for this
project was a physical object. Molds of the historic railings captured their size, shape, and style down to the most minute detail, allowing them to be recreated exactly.
After creating the molds, we were able to cast 3D components in aluminum. O’Brien Metal relied on
the shop’s fabrication expertise to painstakingly chase and machine each piece—touching up imperfections, and bringing out the subtlest and most eye-catching aspects.
The new railings were seamlessly incorporated into the built environment, alongside the historic architectural elements and the surrounding landscape.

Client Testimonials

Eric & John worked well together throughout the process, bringing life to the most intricate details in the design. The results are great and it’s a pleasure to work with them.” - Tim Schwertfeger, Owner

“A true collaboration in every way. O’Brien Metal beautifully captured all of our goals for this portion of the project.” - Eric J. Smith, AIA

Architect-led design build approach yields innovative stainless steel railing solution & stand-out results in the built environment

Tue, 15 Nov 2011 14:01:00 -0500

Peter Gluck and Partners Architects, along with their construction arm, ARCS Construction Services, partnered with O’Brien Metal to create an stainless steel railing solution for the exterior of a lakeside Chicago residence. The goal was a railing which would blend with the residence’s defining beauty—both its unique architectural design and the neighboring Lake Michigan shoreline.

Situation/Challenge:

The Cascade House, designed by New York architecture firm Peter Gluck and Partners, cuts into the Lake Michigan bluff. The property is orientated for panoramic views of the Great Lake. Harmonizing the new railing with both the landscape and the house’s unique design required strong, consistent coordination between the on-site design team (ARCS, led by Jim True) and O’Brien Metal.

Goals:

Translating the new design into architectural details that met the aesthetic, functional, and construction requirements of the existing property and its surroundings.
Blending into the house’s landscaped lawns, terraces, and bluffs, designed by Hoerr Schaudt Landscape Architects.
Incorporating sophisticated hidden connection details into the design that allowed for a highly secure and safe environment.
Precise detailing, measurements, and engineering calculations to ensure all elements fit together.
Ensuring the specialty brush finish would not only aesthetically marry the beauty of the house but also withstand sometimes-harsh lakeside weather conditions.

Results:

The custom-designed and fabricated railings were created with a stainless steel 304 alloy framework with stainless steel infill mesh. The solution spanned the property’s green roof terrace, boat house, and master terrace, as well as the Lake Michigan Bluff.
Strong coordination and partnering among Peter Gluck and Partners, ARCS, and O’Brien Metal yielded a robust and elegant architectural solution—on time and on budget.
“Working within their architect-led design build methodology was eye-opening and a dramatically smarter way of approaching a project, versus the traditional model. Jim True and his team were great to work with and were side by side with my team to quickly work through any obstacles that came up. It was a highly efficient process that produced stand-out results.” – John O’Brien

Client Testimonial:

“John and his team exceeded our expectations despite the demanding level of detail. The consistent enthusiasm, craftsmanship, and technical knowledge they brought to the table made for a productive working relationship. I look forward to working with John again.”
