Welcome to Wheaton Revitalization News! Wheaton Revitalization News is an email distribution list that will provide frequent updates to the surrounding community on the Wheaton Revitalization project. The purpose of this distribution list is to provide you with project updates and construction activities. For additional information on the Wheaton Revitalization Project please visit http://www. Look Ahead – Week of March 11 to March 17, 2018 Executive Summary The project continues to track on-schedule and within budget. The key activity on site this week is plumbing of the geothermal system. See Geothermal System below. Demolition of the Mid-County Regional Services Center (RSC) Building Demolition of the Regional Services Center (RSC) Building commenced on Monday, February 12. Demolition and cleanup is expected to take 6-8 weeks to complete. The contractor continues to carefully dismantle the RSC building where it adjoins the Triangle Building to its north. In addition to dismantling the RSC building where it adjoins the Triangle Building, the contractor commenced with the larger scale demolition with the use of a hydraulic excavator with a special attachment to chew away at the structure. (see photo) The area adjacent to the demolition is protected by fencing and plywood barriers. WMATA has reviewed and approved the building demolition plans including areas of close proximity to WMATA operations. Traffic operations along Reedie Drive have not been affected by the demolition and pedestrian movement will remain unchanged except for the closure of the “cut through” walkway adjacent to the Regional Services Building leading from Reedie Drive to the Metro stairs. Signage will be posted. Foundation Construction Construction of the building foundation is ongoing. The contractor continues with construction of individual concrete footers. All footers are tied into underlying rock, 10 feet below the footers, with the use of down anchors. Tie-down anchors were drilled earlier in the project and are 20-foot long steel rods that are embedded and grouted into underlying rock typically 10 feet beneath the building foundation. The tie-down will offset any hydrostatic pressure of normal elevations of groundwater present at the site. Geothermal System Plumbing of the geothermal wells is the key activity on the project this week. The 150 geothermal wells are now being connected (plumbed) in 15 wells circuits. In all, ten 15 well circuits will be developed and tied into a single manifold at entry to the building. Each circuit is pressure and flow tested before being tied into the circuit. This horizontal plumbing will continue over the next several weeks after which the 18-inch steel reinforced foundation slab will be placed. Site Dewatering Foundation construction requires the continuation of site dewatering. Generally speaking, the 16-deep dewatering wells, operating around-the-clock, are pumping 30 gallons of groundwater per minute (30gpm), half of what was expected. This clean water is discharged into the storm drain system as designed. All water discharged from the site is tested and treated for proper pH levels, if necessary, per the Maryland Department of Environment (MDE) requirements.
