International Concrete Repair Institute (ICRI) 2015 Project Award Winners. Excellence in High-Rise Repair for the Emergency Structural Repairs conducted at the Dolphin Towers Condominium and Project of the Year Finalist


Dolphin Tower

NATIONAL COUNCIL OF STRUCTURAL
ENGINEERS ASSOCIATION
(NCSEA) 2015 OUTSTANDING
PROJECT OF THE YEAR


Sarasota, Florida



In late June 2010, the Dolphin Tower's residents were evacuated from the building after a key concrete transfer slab, which holds its 117 residents, cracked on the fourth-floor of the condominium located in Sarasota, FL. The scope of work involved structural reinforcement of the Dolphin Tower’s foundation, column enlargements and shear wall installations, shoring and repair of the fourth-floor transfer slab. Removal and replacement of exterior CMU walls with poured in place reinforced concrete shear walls, reinforcement of carbon fiber & addition of post-tension beams, repairs on the upper levels of the tower to relieve some overstressed slab locations and increase the wind load capacity based on the new building codes was also conducted.

1000 Vermont Avenue

OUTSTANDING REPAIR
PROJECT AWARD FOR THE
1000 VERMONT AVENUE
FACADE REPAIRS

Washington, DC



The building, located at the corner of K Street and Vermont Avenue in Northwest, Washington D.C., was built in the 1960s and consists of a twelve story structure with continuous ribbon window and precast concrete bands. The 12th floor contains a recessed balcony area along the Vermont and K Street elevations. The floors up to the 11th level contain precast panels, approximately 48” tall and 36” wide that are connected to each floor slab. However, the 12th floor and the main roof precast panels are supported by steel lintels and a masonry parapet wall. There is a large precast bull-nose coping on top of the exterior vertical precast and masonry parapet wall.

The intention of this project was to repair, restore and waterproof the existing masonry parapet wall, precast bull-nose, and steel lintels on the 12th floor and roof level along the K Street and Vermont Avenue elevations. In addition, all facade sealants and glass sealants were replaced on the K Street and Vermont Avenue elevations, the precast coping stone sealants on the roof level were removed and replaced, and the steel lintels from the 2nd to the 11th floor were cleaned and painted.

EXCELLENCE IN THE REPAIR,
REHABILITATION, AND STRENGTHENING
& OUTSTANDING REPAIR PROJECT
FOR THE MOUNT CARMEL
SBR TANK #1 REPAIRS

Mount Carmel, Pennsylvania



The MCMA Wastewater Treatment Plant was built in 1975 and it was originally designed for 1.5 mgd average daily flow & 2,500 lbs/day of organic capacity, but on September 2011, the devastation of Hurricane Sandy played its toll on the SBR Tank #1 causing slab buckling, foundation movements, foundation wall displacement, walkway displacement, and column structural damage. Therefore, from May 2013 to January 2014, CP&R performed a $1M repair on the SBR Tank #1. Repair sequencing was systematically designed to stabilize the structure while allowing the adjacent tanks to stay in full operation as well as to not jeopardize the structural integrity of the post-tension foundation slab and walkway bridges.

THE PRATT STREET GARAGE

Baltimore, Maryland



The work consisted of removal and replacement of the existing topping slabs at levels P-1 thru P-9 as well as miscellaneous concrete repairs to all pre-cast double T’s and beams. CP&R was also in charge of replacing all of the expansion joints and coating at the expansion joints thru these same levels.

The repairs included drain work, waterproofing over occupied space, concrete repair, coating, expansion joints, pavers placement, and electrical work. The Marbury Garage is located in Baltimore, Maryland.













 

ICRI 2009 Project Award Winners


The Pentagon

PROJECT OF THE YEAR: Low-Rise Category
PENTAGON RENOVATIONS
EXTERIOR WALL REPAIR AND
INTERIOR STRUCTURAL REPAIR

Arlington, Virginia







The Pentagon, designated a National Historic Landmark in 1992, has never undergone a major renovation and, after more than 60 years, renovation is essential in order to meet current health, fire, and life safety codes and provide reliable structural, electrical, and mechanical systems. Absent a major renovation, the building's infrastructure will become increasingly unreliable and soon unable to effectively support the headquarters and nerve center of this national military establishment. Major building systems have deteriorated to such an extent that repairs are no longer effective and entire systems need replacement.

The construction of the Pentagon began on September 11, 1941, and over 4 million square feet (371,612 square meters) of floor space was completed in 16 months. The Pentagon is considered the world's largest low-rise office building. It is a five-story concrete structure with five distinct rings. Above the third floor, each ring is separated by an exterior space known as a lightwell. The speed of construction and a different standard of quality control left many areas of the lightwell walls with inadequate concrete cover over the reinforcing steel, sometimes less than 1/2 in. (12.7 mm). This lack of cover, combined with carbonation of the concrete, lead to corrosion of the reinforcing steel. As the steel corrodes, it expands up to ten times its original size, causing spalling of the concrete. It is estimated that there are 250,000 square feet (23,225.7 square meters) of spalled concrete in the lightwell walls.

ICRI 2007 Project Award Winners


Country Club Towers

AWARD OF EXCELLENCE: High-Rise Category
COUNTRY CLUB TOWERS APARTMENTS:
BALCONY, PLAZA RETAINING WALLS,
AND GARAGE IMPROVEMENTS

Arlington, Virginia






The Country Club Towers Apartments improvement project was a complex project, yet was successful with strong cooperation between the owner, contractor, and design engineer. The repairs involved two plazas, balconies, a two-level underground garage, two retaining walls, two French drains, and a loading dock replacement. The cost of the project was $4.2 million dollars, and took 484 calendar days to complete.

The engineering consultants designed the plaza elements including the structural and waterproofing aspects of the items in the renderings and drawings. Included in the specifications were concrete repairs at the plaza decks, balconies, and garage, waterproofing the plaza decks, new concrete walls and sidewalks at the plaza decks and on grade, new masonry terraces, new asphalt pavement, new masonry signs, applying CIT and traffic bearing membrane to the garage slab, installing a new retaining wall at the pool deck, and installing pedestrian coating and new railings at the balconies.

The repair project began in December 2005 and was substantially complete in March 2007. Most of the project went as expected but there were several conditions that were not anticipated throughout the project that caused alteration of some aspects of the original repair design. However, even with these unforeseen conditions, coordination between the owner, contractor, and designer ensured the success of the project.

EXCELLENCE IN THE REPAIR OF
HIGH-RISE STRUCTURES
AWARD FOR THE FAÇADE RESTORATIONS
ROSS HALL
THE GEORGE WASHINGTON UNIVERSITY

Baltimore, Maryland





The repairs included removal of the deteriorated and unsound concrete, treatment and repair of reinforcing steel, and the placement of a repair material to match the existing architectural finish of the building. Other repairs included crack injection, tuckpointing, and caulking. Upon completion of the structural repairs, the surface of the building was treated with a mineral based coating to provide a preventative waterproofing for the unrepaired concrete areas, protection of the new repairs, and to give the building a uniform appearance.
