Costello Construction Nears Completion of Innovative Museum Project




We are honored to share that Costello Construction, along with the Rockville Department of Recreation and Parks, the Rockville City Police Department, and Wheeler Goodman Masek Architects, has received the 2013 Peerless Rockville Award for outstanding achievement in the adaptive restoration of Rockville’s former post office building for use as the Rockville City Police headquarters, and the newly constructed Police Operations Center.

Costello Construction - Rockville Police Station

Costello Construction’s work for the Rockville Police Station included the renovation/historic restoration of the existing, former United States Post Office building and the construction of a new 14,500 square foot, three-story “Annex” building on the same site. As a significant historic structure, the facade of the existing building was meticulously restored and the interior of the Post Office completely renovated, including a full restoration of the historic lobby and vestibule.

The station held its grand opening and dedication in October of 2012.

Costello Construction self performed site work, excavation, underground utilities, concrete, below grade waterproofing and the green roof installation.

The National Museum of Health and Medicine recently achieved a milestone that we couldn’t be more enthused or proud to have played a part in reaching.

On May 21, the museum re-opened its doors as part of its 150th Anniversary celebration in its new location and building, designed and constructed by Costello Construction.

Completed in August of 2011 and located in Silver Spring, Maryland, the 20,000-square-foot building is one of the first blast resistant Tilt-Up concrete buildings in the United States. Additionally, the building was designed and constructed to achieve a LEED-Silver rating – making this one of the most unique and innovative projects we’ve completed.

The museum, which houses an incredible collection of war-time artifacts, truly is an impressive showcase of U.S. military and medical history. Bullets, amputated limbs and skulls include just a few of the intriguing items on display.

“The museum has 25 million artifacts,” said Tim Clarke Jr., the museum’s deputy director for communications. “Including the world’s largest collection of microscopes, a soldier’s notebook that stopped a bullet and a metal breastplate that failed to.” – The Washington Post

Because of the nature of the items housed at the Museum – highly sensitive, one-of-a-kind artifacts which are irreplaceable – we needed to ensure that the design and construction of the building protected the interior while still providing functionality. In order to preserve these artifacts, humidity levels inside the Museum must remain very high, creating construction concerns that required insightful solutions, such as the site-cast concrete spandral panels and the use of Tilt-Up concrete to create a substrate that provided a vapor barrier constructed to the most stringent of standards.

At the end of the day, we knew how to build this extraordinarily complicated facility and we really believe our innovation and dedication was the driving force behind the success of the project.

So, the next time you visit our nation’s capital, we recommend taking the short trip to Silver Spring to tour this magnificent museum. And, while you’re admiring all of the amazing, somewhat eerie and historic items inside the building, we ask that you take a minute to step back and admire the innovation and ingenuity that houses it – let us know what you think!

Dear Friends, Colleagues and Associates:

It is with the deepest of regret that I write to inform you that my friend and associate, Dan Fellegara
was struck by a moving vehicle while visiting friends in New York City early yesterday morning. Dan was
immediately rushed to the hospital where he was unable to be revived.

Details of this tragedy remain fluid and all of us at Costello Construction are devastated and shocked by
this sudden and epically tragic event. Dan was an outstanding and exemplary employee and a personal
friend. He was reliable, professional at all times, diligent and detailed. Dan Fellegara is irreplaceable.

As details become clearer and information regarding upcoming events make their way to Costello
Construction, we will immediately pass them along. In the meantime please keep Dan and his family in
your thoughts and prayers. Today would have been Dan’s 29th birthday.

December, 2011 – Baltimore, MD – Costello Construction continues an impressive streak of recognition with the Silver Spring Civic Building at Veterans Plaza earning the esteemed 2011 Public Building of the Year award from the Maryland chapter of the American Institute of Architects (AIA).

“This project perfectly fit the award – it was a project that we could all very clearly identify as offering something intensely public to the city of Silver Spring. The project seemed to be extraordinarily well detailed and really exceptional. It has a huge scale which allows it to have presence along the plaza and it seemed to create a kind of physical representation of a place where people could gather for communal activities. This was an obvious choice for this award.” – AIA Maryland Jury Comments

The multi-use facility, designed by internationally recognized Machado and Silvetti Associates, was constructed with the utmost detail. Amenities include multi-media resource and meeting rooms, a great room with the capacity for 800 people, an art gallery, open air courtyard, ice rink, office spaces and the Round House Theatre. Notable elements in the building include fritted glass used for climate control, IPE siding, fiber component rain screens, natural stone and bamboo floors and a high efficiency HVAC system that has magnetic bearings to reduce electricity consumption.

The project also gained honors from AIA New England, earning a 2011 Special Citation for Design Excellence award.

The AIA Maryland Design Awards aim to encourage and recognize distinguished architectural achievement and focus public attention on the Architect’s role in shaping the quality of life through design excellence.
