Famous American buildings made out of limestone
Limestone has been utilised throughout the ages and is a popular material within building and construction. We take a look at famous American buildings made out of limestone which still remain today and are iconic within America.
The Pentagon, United States
Designed by American architect George Bergstrom and constructed by contractor John McShain, reinforced concrete was implemented alongside Indiana limestone for the building’s exterior as a result of the lack of steel from the Second World War.
Rebuilt after September 11 2001, the building now houses over 23,000 employees and is one of the most famous buildings within America.
The Lincoln Memorial, United States
Constructed to honour Abraham Lincoln, 16th President of the United States, the Lincoln Memorial was built between 1914 and 1922. Designed by architect Henry Bacon and incorporating classical features, the build also has a statue of Lincoln within the interior, constructed by Daniel Chester French.
Interior walls and columns are made from Indiana limestone, beside marble and granite which have been utilised to represent different areas within the United States.
The area is still a tourist attraction and has become listed on the National Register of Historic Places since 1966.
The Empire State Building, New York
The iconic Empire State Building, situated in Manhattan, New York is the fifth tallest skyscraper in America and has been a National Historic Landmark since 1986. Completed in 1931, it has become the tallest building to obtain the Leadership in Energy and Environmental Design after an extensive $550 million renovation in 2010.
Reaching a height of 443.092 metres, the building incorporates over 1,000 businesses and over 21,000 employees, alongside 73 elevators and observation decks. The construction is now the second largest single office space within America.
Washington National Cathedral, United States
Built from Indiana limestone, the Washington National Cathedral took over 80 years to build, but is now the sixth largest cathedral in the world. Completed in 1990, the cathedral incorporates Gothic architectural styles, with over 400 gargoyles, stained glass windows, ornate carvings and pointed arches within its design.

Construction workers urged to down tools for mental health
The construction industry is being encouraged to stop all work for one hour to focus on the importance of physical and mental health. The plea is part of the ‘Stop. Make a Change.’ (SMAC) campaign which is asking construction organisations across the country t spend an hour thinking about physical health conditions, such as respiratory health, work-related stress, as well as mental health conditions including, but not limited to, depression, anxiety, OCD, and bipolar disorder.
This year, the campaign, which takes place from 11 to 22 October, will focus on individual workers, placing particular emphasis on how they have been affected by the Coronavirus pandemic. In addition to encouraging workers to consider their health, safety, and wellbeing, they will also be asked how those areas can be improved
Andy Mitchell, co-chair of the Construction Leadership Council, said: “Our industry workforce is crucial to all of our future successes. We recognise the heroic efforts these workers have undertaken during the pandemic, and want to make sure that, as the industry hopefully emerges from COVID-19, we continue to look after everyone’s health, safety and wellbeing.”
Around 200,000 people took part in the campaign in 2019, which has been running since 2017. SMAC’s website also offers conversation starter kits to help encourage people to talk about their emotions and wellbeing, making it as natural as possible.
Suicide rates in the construction industry are increasing
A study by Glasgow Caledonian University found suicide rates among construction workers had risen to 29 per 100,000 in 2019 from 25 in 2015. Suicide rates among labourers increased by more than 50% from 48 per 100,000 in 2015 to 73 per 100,000 in 2019. However, the rate in non-construction-related industries has fallen, with just under five people per 100,000 taking their own lives in 2019 in comparison to 7 people in 2015.
