METZ RESERVOIR RENOVATION IN GREENBURGH, NEW YORK

This stage of scaffolding is about 1 month into the project.

The Metz Reservoir Renovation Project was headed by a newly signed contractor, NATGUN Corporation. NATGUN constructs wire-wound pre-stressed concrete water tanks using a unique method of construction which encompasses the use of a scaffold as a pattern for the tank. The project is a 3 million gallon water storage tank located in Greenburgh, New York and is one of four projects in 2009 between NATGUN Corporation and the Empire State Regional Council of Carpenters. The other projects are a 1.5 million gallon water storage tank at Cornell University in Ithaca, 0.61 million gallon water storage tank as part of the Rensselaer Power Plant project in Albany, and the 0.17 million gallon water storage tank in Chesterfield. The Council entered into the agreement with NATGUN in order to build a relationship for the purpose of continually employing our members in the construction of these unique water tanks.

Five Local 11 carpenters worked on the project that ran from March to June 2009, contributing 1,925 man-hours towards the Funds. Their impressive workmanship did not go unnoticed and NATGUN was extremely pleased that the job was completed successfully in the timeframe allotted. The water in the tank will provide backup during dry summers for citizens of New Rochelle. The community benefits from this tank as well because water is now contained in the tank, whereas in the past, an open reservoir attracted mosquitoes and geese causing contamination. The new water tank allows for higher levels of security and less contamination providing benefits to the community.

About 15-20 precast concrete roof panels were put into place each day during the construction of this project.
