Term:
tooled margin

Definition:
a masonry finish that gives the appearance of a band at the edge of a stone, typically one inch or more in width (Source: International Text Book Company, International Library of Technology 31D, 1923)

In traditional stone cutting margins, also called drafts, were used to layout the face of the stone and square it for installation in the wall. In softer stones, such as limestone, the margin is typically hand tooled with a chisel and mallet to create parallel fluted grooves in the stone. Modern machine cut tooling tends to be square in profile rather than fluted and lacks the slight irregularities of handwork that makes it pleasing to the eye.

How far will we go for preservation?

2014-06-27 Posted By: Patty Weaver

To another country! Vance Kelley, Treanor Preservation principal, and Julia Manglitz, Treanor Preservation project manager, recently travelled to Toronto, Canada to present a paper they co-authored at ASTM International’s Symposium on Masonry 2014.

While in Toronto they took in a few of the sights, including the CN Tower. The CN Tower is a 1,815.4 ft high concrete communications and observation tower in Downtown Toronto. It was completed in 1976, becoming the world's tallest free-standing structure and world's tallest tower at the time. It held both records for 34 years until the completion of Burj Khalifa and Canton Tower in 2010. It remains the tallest free-standing structure in the Western Hemisphere, a signature icon of Toronto's skyline, and a symbol of Canada, attracting more than two million international visitors annually.

In 1995, the CN Tower was declared one of the modern Seven Wonders of the World by the American Society of Civil Engineers. It also belongs to the World Federation of Great Towers, where it holds second-place ranking.

Photobombed! Vance and Julia were just trying to take a nice selfie when No Climbing Man jumps in the background. How rude.Photobombed! Vance and Julia were just trying to take a nice selfie when No Climbing Man jumps in the background. How rude.

Shoptalk: Compatible Addition

Term:
compatible addition

Definition:
building addition that is visually distinguishable from the historic building yet respects the original architecture in design, scale and materials; addition that resembles the historic without duplicating the original design (Source: National Park Service, Preservation Briefs, #14 New Exterior Additions to Historic Buildings: Preservation Concerns)

Examples: See More Examples

Gwynn Hall’s, University of MissouriColumbia, southwest entrance tower addition on the building's rear elevation is compatible with the historic building’s massing, size and scale. The addition was differentiated from the historic gothic-style building through modern design—smooth stone instead of rough cut and glass elements—yet remained compatible with the use of appropriate materials and design elements—white limestone and narrow windows.

Treanor Historic Preservation Staff to Make International Presentation

2014-06-12 Posted By: Patty Weaver

ASTM STP Mastheads

Julia Mathias Manglitz, AIA, and K. Vance Kelley, AIA, both of Treanor Architects, will present their technical paper, “Success and Failure in Applying ASTM Standards to the Evaluation and Rehabilitation of Historic Masonry Structures–A Case Study,” at ASTM International’s Symposium on Masonry 2014 in Toronto, Canada later this month.

The paper, co-authored with and Mark Hodges, PE, of Dudley Williams Associates, presents a case study to demonstrate the applicability of ASTM standards during the evaluation and rehabilitation of historic masonry. The case study focuses on the evaluation and repair of an existing structure, Fort Leavenworth’s Grant Hall (Building 52) Clock Tower, and the challenges of applying materials standards and specifications that were developed primarily for new construction.

Shoptalk: Pressed Tin Ceiling

2014-06-11 Posted By: Patty Weaver

Shoptalk—deciphering architectural and historic preservation jargon one word at a time!

Term:
pressed tin ceiling

Definition:
a tin ceiling comprised of stamped or pressed sheet metal tiles; popular between 1880 and 1930 when they were mass produced; used in lieu of elaborate decorative plaster ceilings

Pressed tin ceilings are durable, long lasting and easy to install. If pieces are missing or are heavily damaged, the pressed tin ceilings can also be relatively easy to restore if the same company that originally produced the ceiling tiles is still in business. W.F. Norman is a pressed tin company native to Missouri that still uses its original dies from 1898! Watch this video to learn more about the pressed tin industry and process of stamping ceiling tiles

Treanor's Student Housing Wins MEED's Sustainable Project of the Year

2014-06-05 Posted By: Emily Bengoa

Now in its fourth year, MEED’s quality awards have attracted substantial interest from companies and individuals across the GCC construction industry. Through its annual awards, MEED seeks to recognise the finest achievements in the GCC projects industry, and to celebrate all those who have made possible the exceptional design and delivery of major projects.

The Qatar Foundation Male and Female Student Housing project was commended in the two key MEED Quality Award categories of ‘Sustainable Project of the Year’ and the ‘Louis Berger Building Project of the Year’.

Qatar Foundation has received numerous awards for its eco-friendly developments and has been recognised by the U.S. Green Building Council for its commitment to green building design. It has most recently been presented with the Sustainable Leadership Award at the World Corporate Social Responsibility Congress in Mumbai. For its exceptional Male and Female Student Housing Project, Qatar Foundation won last year’s Big Project Middle East Construction and Sustainability Award of Excellence in the Sustainable Solution of the Year category.

Engineer Telefat added: “The Male and Female Student Housing Project, which is located within the Education City campus consists of the highest concentration of independently registered platinum LEED buildings by the U.S. Green Building Council and we are delighted to see this project commended by MEED. This recognition is a true honour as it highlights the sheer hard work that has gone into this exciting undertaking.”

The student housing, which has been developed by Qatar Foundation and designed by Burns & McDonnell, in partnership with architectural firm Treanor Architects, green building consultants Vertegy and ASTAD Project Management, successfully integrates a highly functional and durable design.

It has earned 12 Platinum LEED certifications in the category of ‘New Construction’ from the U.S. Green Building Council. The development comprises two individual male and female complexes. Each complex spans 36,000 square metres and boasts five residential buildings, as well as a community centre. State-of-the art sustainable technology and energy-efficient systems are used throughout the complex.

To assist the students in keeping track of their green footprint, each housing unit contains a monitoring system that checks an individual’s water and energy consumption. The complex is also equipped with clean power sources, a solar-panelled roof and wind turbines that generate energy at gusts of 10 kilometres or more.

Shoptalk: Prism(atic) Glass Tile

2014-06-04 Posted By: Patty Weaver

Shoptalk—deciphering architectural and historic preservation jargon one word at a time!

Term:
prism glass tile

Definition:
an architectural glass tile, typically about 4”x4” in size, that redirects natural daylight through reflection and refraction into a building

Prism glass tiles became popular after they were patented and first commercially produced by the Luxfer Prism Company starting in 1897. They were particularly popular in transom windows above storefronts along main streets with structure similar to a stained glass window using zinc came and lead solder joints to hold the glass tiles together.

Today, preservationists struggle to save these transoms. Prism glass tiles are no longer produced, making it difficult to properly restore missing tiles. Additionally, these transoms face a similar battle that many stained glass windows face. Without proper care and maintenance throughout the lifespan of an exterior leaded glass window, it can fall into extensive disrepair making restoration all the more difficult and quite pricey.

Want to learn more about prism glass? The Historic Prism Glass Companies of the United States is a fantastic resource outlining its many uses throughout the years. The National Park Service’s Preservation Tech Note on “Repair and Reproduction of Prismatic Glass Transoms” is also a great resource.
