Mallory Hat Factory Remediation

Mallory Hat Factory Remediation

The **Mallory Hat Factory Remediation **project was designed by Arcadis Engineering.  This project is the remediation of the former Mallory Hat Factory property and testing of contaminated non-hazardous soils to meet residential soil criteria for occupancy.  Initial plans entailed transforming the abandoned Mallory Hat Factory into transitional housing facility, and the Danbury Zoning Commission unanimously approved changes to its regulations to allow the site at 88 Rose Hill Ave. to be redeveloped as a 20-bed residence to be operated by the Women’s Center of Greater Danbury. The purpose was to house women victims of domestic violence and abusive situations. The Danbury City Council initially approved former Mayor Mark Boughton’s request to transfer the city-owned property to the Women’s Center in 2017. 

Construction Services has been working with the City Engineer and the Engineering Department to move the project forward.  The remediation portion of the project was at Substantial Completion as of June 2020, ahead of schedule and within budget. We received our final permit from CT DEEP for the injection of a Chemical Oxidation agent into four wells on-site Red Technologies has ordered the material then schedule work. The CT DEEP Chemical Oxidation Permit requires the L.E.P. Arcadis to install several additional monitoring wells onsite down gradient from the injection wells the six wells have been installed and the ground water sampled. Red Technologies introduced the Persulfate Chemical with tracing dye into four wells designated for chemical injection Once this is complete the project is at 100% completion in November 2020. The close-out Phase is with the contractor and L.E.P. is underway. The project has been administrated and managed in house by Construction Services.

Heritage Plaza at Danbury City Hall

Heritage walk was dedicated in October of 2017 as a celebration of all the nationalities and cultures that comprise the City of Danbury.  Developed by the current Administration, City Planner, Director of Public Works/City Engineer and under the supervision and direction of City Construction Services, the project included a complete exterior site renovation fronting the City Hall of Danbury.  The focal point of the project is Heritage Walk itself, which is the concrete patio area on the west side of the property fronting City Hall.  This area is a true dedication to the many different cultures and nationalities that make up this community by giving them the opportunity to create a monument signifying their contribution and development to the City of Danbury since that culture's settlement in Danbury, for display on the walkway. 

Other highlights of the project are a relocation of a time capsule first entombed in front of city hall in 1985 and now relocated with an identifying bronze plaque and to be reopened in the year 2285.  At the northwest portion of the City Hall property at the corner of Deer Hill Avenue and West Street is the city's new message center.  This high definition electronic display screen provides both informative and vital information with animation to the public at large and is another major focus point of the project on the property.  Mayor Mark Boughton and his staff were instrumental in how information was to be broadcast to the citizens and it's visitors to our City. 

Finally, a superb landscape plan was put in place with a variety of plantings ranging from flowers and grasses to shrubs and trees that adds beauty and sophistication to the City Hall Complex of Danbury Connecticut.

Danbury High School Tennis Courts

New tennis courts constructed at Danbury High School are manufactured with "post tension concrete".  This type of concrete construction lengthens the life of concrete by pre-stressing the concrete with lineal cables running through the slab in a grid pattern.  By adding tension to these cables, it make the concrete stronger, extending its life and reduces cracking.


Tarrywile Dam Repair

The Tarrywile Dam is in need of concrete repair which requires lowering of the water level of the Tarrywile Pond to make necessary restoration of the concrete face, the top of the dam, and the spill way.  A fence was also installed along the top of the dam to insure the safety of park goers.  

Still River Sediment Removal

In accordance with DEEP (Department of Energy and Environmental Protection) and Army Corps of Engineers' requirements, it was identified that sediment which accumulated in a portion of the Still River be removed to insure that Flood Damage Reduction (FDR) is maintained.  The inspection by the Corps produced a "Minimally Acceptable" rating which lead to the necessity of the project.  Approximately 2500 lineal feet on both shore lines of the river were cleared of vegetation that had overgrown the banks and sediment which collected in the channel was removed, insuring continued flood protection for the City of Danbury. 

Jefferson Avenue Bridge Rehabilitation

This project consisted of the full rehabilitation of the bridge crossing at Jefferson Avenue near the downtown area of Danbury.  An inter-city water course the bridge spanned is know as Blind Brook and much of it is not visible to the public, as decades of private and public development, including infrastructure has covered it over decades.  Jefferson Avenue spans two major arterial roadways connecting Southern Boulevard with West Wooster Street.  The project included a reinforcement of existing bridge piers, deck replacement, abutments and other structural improvements. 

Reservoir Street Culvert Replacement

The Reservoir Street Culvert Replacement project was the full replacement of a culvert which reached the end of its useful life span. The culvert dissects Reservoir Street in the south portion of Danbury near the Bethel town line.  The box culvert was completed ahead of schedule and within budget.  This is a heavily traveled roadway with over 2000 trips per day and is a vital artery connecting the two municipalities.  In addition to the culvert replacement, the roadway area has been widened at the intersection.  Reservoir Road has been improved with resurfacing throughout the roadway.
