A New Modern Facility that Upgrades and Improves Building Capacities and Other Ancillary Support Systems for Vital Water Infrastructure

This project includes the construction of two new state-of-the-art buildings at the Bucklin Point Wastewater Treatment Facility. The Maintenance and Storage Building is a 28,000 square-foot two-story building with a brick and metal panel facade. The space includes storage on the first floor and a mix of office and maintenance space on the second floor. The New Operations Building replaces the existing Administration Building (demolished as part of the project). This building is similar to the Maintenance building, in appearance, but includes more office and assembly space among its total 22,000 sf. This building now includes the main SCADA control room that was relocated from the Screening and Grit Building. There’s also a lab for conducting water tests for the water treatment facility. Other areas include a boardroom, a lunchroom and kitchen, a locker room, and an exercise area.

During preconstruction, the team was focused on multiple critical tracks including Soil Borings/Survey and Permitting with RIDEM, program verification and space planning, two phases of early bid packages, and four phases of CDs. Deliverables for each of the CD sets included close coordination with the owner and end users, constructability reviews, value engineering options, and estimating support. This process also included several design-assist subcontractors for mechanical, electrical, and plumbing scopes of work.

Project Highlights
  • During construction, the facility needed to remain open 24/7. This required the fit-out of a temporary office, lab, and Supervisory Control and Data Acquisition system (SCADA) facilities for the Narragansett Bay Commission to maintain plant operations throughout the construction phase.
  • Detailed BIM coordination helped inform the design process. The project team held multiple weekly meetings to track design progress utilizing Miro as a scheduling tool as well as project update meetings and design review meetings with the owner and end users.
  • Logistics and schedule development were a critical part of preconstruction and the team focused on vetting and updating these plans to ensure that the project did not disrupt plant operations at any time.

Project Contact

We started the project with very preliminary design drawings. We were impressed with how DOC worked with the entire project team to bring the final design documents together in a very short period of time. This task was made all the more difficult as most people were working remotely during the global pandemic.

DOC oversaw a very collaborative effort that used several Lean management practices. The firm did a great job of keeping all of the team members focused on the tasks that were critical to keep the project on schedule.

Urban Senior Housing Renewal: Complex Renovation Balances Occupancy, Logistics, and Innovative Design

The Sussman House was originally constructed in 1965 as a concrete cast 9-story superstructure with copper sheet metal facades. This high-rise apartment building, home to seniors and disabled households, needed major interior renovations and exterior repairs. The scope of work includes kitchen and bath upgrades for 100 residential units, upgrades to building MEP systems, replacement of finishes in common areas, window replacement, roof replacement, and exterior recladding of the building. The project also includes reconfiguring an attached first-floor common room and property management office. The building was substantially occupied throughout the construction process, with unit renovation being undertaken in a phased approach.

Project Highlights
  • Logistic Complexity: Occupied building renovation on a tight urban site requires detailed phasing and site logistics plans to allow residents safe access to the building and their units during construction
  • The project utilized the Design Assist method for early bid packages for the exterior wall cladding and curtainwall systems
  • The project team used Takt Planning to establish a rhythm, continuity, and consistency of the workflow. This method allows worker counts, material inventory, information, equipment usage, supervision, and administration needs to be leveled with consistency.

Sustainable Campus Expansion: Historic Building Renovation and CLT Addition Enhance Academic Spaces

Amherst College, responding to a dire shortage of faculty office and academic space on campus, and supported by a generous gift from alumnus Seth Frank, created a new home for the Center for Humanistic Inquiry, the history department, and some additional faculty members.

The project is the complete gut renovation of an existing 4,200-square-foot building from the mid-1800s, along with a new 14,200-square-foot addition and hardscape. The existing brick building envelope was saved—through masonry repairs—but the interior floors, MEP systems are completely removed and replaced. The new three-story addition is a combination of wood and steel structure, with high-end curtainwall (Shuco) systems.

DOC provided self-perform work services for the restoration of window replacements within the existing building along with exterior siding install on the new addition.

Although boasting a modern style with increased natural light and open space, the intent of the design was to preserve and highlight elements of the house that form its core. Inspired by the Lyceum of ancient Athens, Greece, interior spaces are arranged to encourage collaboration, conversation and interaction for students, faculty and the Amherst community. The facility features a state-of-the-art environmental design to achieve operational sustainability and minimize the carbon emissions from construction.

The exterior hardscape is a combination of concrete, granite, and marble to form a patio space that can be used to host outside events.

Project Highlights
  • The project site is located in an active part of campus, in close proximity to the main campus walkway, student residences, and parking areas
  • Utilizing a cross-laminated timber (CLT) construction to support Amherst College’s commitment to carbon neutrality
  • The building includes a 31-kW roof-mounted solar array
  • The DOC team provided self-perform work for the window replacements along with exterior siding

Revitalizing Infrastructure: Montgomery-Russell Bridge Transformation Enhances Safety, Structure, and Highway Flow for Modern Travel Experience

The $46.9 million rehabilitation of the Montgomery-Russell Bridge located on Interstate 90 over US Route 20, Westfield River and the CSX Railroad in the towns of Montgomery and Russell focused on both the superstructure and the substructure of the existing bridge, lighting and drainage improvements. The rehabilitation of the bridge deck featured a major steel component replacement, and concrete deck work along the 1460ft long bridge. Upgrades included 2-foot left shoulders, 12-foot lanes, 8-foot right shoulders, a wider twin single-faced barrier, and more narrow bridge rails within the existing width of the bridge. Because the scope of work did not include roadway widening beyond the bridge, work took place in multiple stages to facilitate traffic flow at the full capacity of four total lanes, two in each direction.

An Advanced Control Center that Safeguards Critical Operations while Providing Transparency to the Communities it Serves

The Primary Control Center (PCC) is the first of three buildings being constructed as part of the larger Training Facility project for Central Hudson Gas & Electric. These new buildings will not only maintain critical transmission and distribution services for gas and electric to clients, but be at the forefront of managing and controlling the energy that communities rely on.

The project involves new construction of a 43,000-square-foot facility comprised of a steel frame structure on concrete foundation, with cladding composed of ground face and terracotta masonry, CMU’s and sheet metal. The roofing system is a fully adhered EPDM rubber roof system. Aluminum and glass curtain wall make up the entries.

The PCC building is a high security space complete with anti-tailgating security doors, switchable privacy glass, and various continuous construction assemblies to prevent access to critical operations spaces. Outside of the secure areas, there are offices and meeting spaces offering versatility to the center’s use and functionality. There’s a public viewing area to facilitate transparency into what goes on at the center.

DOC managed the console and video display packages which includes the installation of data infrastructure and coordinated video display screens throughout two control rooms used to monitor and troubleshoot Central Hudson’s utility grid throughout the Hudson Valley. The control spaces are 24/7-use-rooms and the video display system is fully redundant and seismically rated.

Project Highlights
  • New construction with program spaces including command centers, call centers, exercise rooms, office and conference room spaces, public viewing spaces, and locker rooms
  • Integrated high level security system inclusive of anti-tailgate doors at the entrance points
  • Designed as an N+1 facility with a backup service to the main services that allow the building to fully function if one of the services is compromised
  • During the site enabling, all the access roads and utilities were built to allow for the construction of the Primary Controls Center
  • Control Rooms have a tunable lighting technology design which is critical to the employees maintaining a healthy circadian rhythm

Revolutionizing Wastewater Infrastructure: Project Bolsters Resilience and Economic Growth, Innovating Pipe Crossings, Treatment Facilities, and Climate Adaptation for a Thriving Region

This $106 million project, once completed, will serve 70 percent of this region’s population. The goal is to upgrade the city’s wastewater infrastructure and increase capacity to accommodate economic growth and impacts of climate change.

The project’s scope of work includes new pipe crossings of the Connecticut River, construction of a new Springfield Regional Wastewater Treatment Facility (SRWTF) Influent Structure on Bondi’s Island, and a new sanitary pump station and screening facility on York Street.

The York Street Project is being built on the former site of the York Street jail, and will connect to the SRWTF on Bondi’s Island through three new 1,200-foot river crossing pipes. The installation was achieved through micro-tunneling of 3 combined sewer pipelines across the active rail lines between the project site and Connecticut River.

The pipelines consist of a 72″ prestressed concrete cylinder pipe, within a 96″ diameter reinforced concrete casing along with two 36″ HDPE force mains each within a 48″ steel casing.

Project Highlights
  • Being delivered Public CM-at-Risk with GMP (Chp. 149-A).
  • The work is being done next to an active rail line.
  • The new plant is designed to pump 62 MGD (million gallons per day).
  • This system will reduce combined sewage overflows by an estimated 100 million gallons per year with 100 fewer discharge events.
  • The pump station excavation extends 50’ below grade and 35’ below the groundwater table through overburden consisting primarily of silty clay. The proximity to the railroad and an US Army Corp. Flood Damage Reduction System Flood wall demanded a support of excavation system that would be rigid enough to limit deflection and watertight enough to prevent groundwater infiltration that could lead to settlement. A slurry wall support of excavation system was selected as it’s commonly used in clay soils in urban settings around existing structures due to the rigidity and water cutoff that is provided when the walls are extended into the underlying rock. In this instance, the project was also able to realize a time savings based on the speed in which this system can be constructed.
