Geiger Brothers assists FBP with disposal site geologic investigations

Under contract to Fluor/Babcock & Wilcox Portsmouth (FBP), Geiger Brothers has participated in studies of the geology at locations being investigated for On-Site Disposal Cell (OSDC) construction on U. S. Department of Energy (DOE) property in Pike County.  The work is part of the Portsmouth Gaseous Diffusion Plant (GDP) Decontamination & Decommissioning (D&D) program.  Fluor-B&W Portsmouth, LLC (FBP) is DOE’s prime contractor performing D&D and remediation.

An OSDC, in conjunction with off-site shipment of higher-hazard materials, is an alternative being considered for more than 2.1 million cubic yards of material that will be generated from D&D.  The OSDC approach would allow for disposition of low-level radioactive, mixed low-level radioactive and Toxic Substances Control Act (TSCA) wastes within the boundaries of the GDP site.

The GDP site is undergoing remediation pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and Resource Conservation and Recovery Act (RCRA).

Using an excavation subcontractor, Geiger Brothers was responsible in early 2012 for the initial OSDC test pit excavation.  The excavation was made to help assess the geology as part of the feasibility study for construction of the engineered disposal facility.  The excavation was approximately 19 feet by 50 feet with 12-foot walls.

Geiger Brothers was responsible for pre-mobilization including submittals and training, mobilization and  site preparation including erosion and sediment control and construction fencing, site restoration, clean-up and demobilization and for managing the removal of top soil and overburden soil and rock, rock trenching, diversion berm, rock excavation, stockpiling, dewatering, backfilling and other specific scope-required activities to complete the test pit excavation and for FBP to perform evaluations.

FBP continued geological studies later in 2012.  A trench dug 27-feet deep and 30 inches wide further revealed geology and confirmed results of previous soil and rock samples.  By extending a camera into the narrow trench, crews from Geiger Brothers and the excavation subcontractor were able to safely and efficiently capture images of the soil composition and layer structure.

Scientists and engineers examined density, permeability and composition of soils and underlying rock formations, in particular checking for flow of water and the presence of fractures that could conduct water.

If constructed, the OSDC design will reflect all geological and hydrogeological information and contain engineered liner and cap systems with multiple layers of barriers and drainage layers to encapsulate the material and comply with stringent Department of Energy (DOE), United States Environmental Protection Agency (USEPA) and Ohio Environmental Protection Agency (OEPA) regulations.  DOE and OEPA will make the final decision for site-wide waste disposition with input from members of the Site Specific Advisory Board (SSAB) and the community.  Final engineering design and construction processes for the OSDC and necessary support facilities then would be initiated.

Geiger Brothers builds new records vault at Pike County site

Geiger Brothers has completed modifications to the existing X-720 Maintenance Building to provide for a new records retention vault at the U. S. Department of Energy’s Portsmouth Gaseous Diffusion Plant.

The construction was done under contract to Fluor/Babcock & Wilcox Portsmouth (FBP) as part of infrastructure and miscellaneous project work being done in preparation for and as part of plant decontamination & decommissioning (D&D)

Plant drawings and documents dating back to the 1950s that are being moved to the new vault were housed in the core of the X-100 Administration Building, which will be demolished as part of the plant D&D project.

The project involved a combination of demolition, new construction, and system reconfiguration.  Part of the challenge was to isolate existing utilities (i.e., electricity, heating, ventilation and air conditioning, and water lines) to ensure the new vault is independent from the rest of the X-720 Building.

The scope of work to construct the new vault specifically included old system and fixture demolition; modifications to an existing restroom; piping modification to existing utilities and new installations; electrical modifications to existing systems and installation of new power panels; installation of a new alternate exterior electrical power feeder and switching; modifications to the existing fire suppression system and new installation; concrete foundations and construction of fire-rated concrete block including fire stops and fire doors; installation of new HVAC units/systems; installation of security doors, locks, hardware and wiring raceways; installation of the fire the alarm system; fire stop penetration sealing; installation of hardened offices and cubicles including walls, wiring and fixtures, finishes, furniture, ceilings and final trim; and completion of final acceptance testing of all systems and installations.

Geiger Brothers installs new data center at Pike County site

Geiger Brothers has completed installation of a new Data Center under contract to Fluor/Babcock & Wilcox Portsmouth (FBP) as part of ongoing infrastructure and miscellaneous project work in preparation for and as part of Portsmouth Gaseous Diffusion Plant Decontamination & Decommissioning (D&D).

The Data Center was placed in mid-January to house information technology operations and to keep the computer network running smoothly as work proceeds on D&D.

Data Center Set

The Geiger Brothers scope of work included a role in design and engineering; the concrete foundation; setting the structure in place; installation of the emergency generator, two air-cooled chillers and associated piping; fencing; and system testing.

Data Center Generator

The new energy-efficient server room was completed in June, encapsulating several servers in a standard shipping container with the capacity to support multiple companies and locations.  All site-wide data now originates from the server room.  Deploying the server room as a modular unit was quicker than traditional methods and more units can be added as needed.

In general, average server rooms use up to 100 watts of energy per square foot. The new server room will only use about three watts per square foot, and, if there’s a power outage, the system will switch to diesel-fueled backup power within 15 seconds. Each rack is supplied with its own dedicated cooling system to minimize downtime. The fire suppression system — unlike that in some server rooms – is safe for occupants.

Data Center Server

The Facility Custodian credited those who made the endeavor a success, including the Fluor B&W construction and project management team and Geiger Brothers, the contractor.

“It was truly a collaborative effort,” he said.  “The leadership and expertise of these individuals provided the right ingredients for executing this project with excellence. This team had an excellent safety record while meeting this very important milestone. Their relentless efforts to complete this project safely and on time were the major factors in its success. This new facility will provide a stable infrastructure that will support the D&D activities throughout the balance of the project.  It’s been a wonderful project.”

Portsmouth West Middle School dedicated; classes in session

GE DIGITAL CAMERA

100_1377 Edited 100_1406 EDITED

Geiger Brothers had the key role in building the recently dedicated new Portsmouth West Middle School.

The Washington-Nile Local School District board had awarded a $9.8 million contract to Geiger Brothers for general trades, HVAC and plumbing on May 12, 2010. The school district dedicated the new building during a public ceremony August 14, 2011, well in time for the start of school on Wednesday.

The new structure was built on the same campus as the elementary and high school buildings, both done in 1997 by KCI, which became part of Geiger Brothers in 2003.

The exterior has brick and metal panels that match the two existing buildings. The structure was built on approximately 12 feet of engineered fill to place it above the 100-year flood plain.

The 67,457-square-foot single-story building is designed for 474 students. The building features 17 classrooms, three project labs, three special education classrooms, an art center, media center, two music rooms and a stage open to both the cafeteria and the gymnasium.  The classrooms are divided into two wings, one for grades 5-6, and the other for grades 7-8.

Total project cost was $16 million, of which 98 percent was paid by the Ohio School Facilities Commission (OSFC). The OSFC accepted the middle school plan as a special-needs project in 2008.

As part of the OSFC program, schools are required to meet state-mandated minimum LEED standards. The purpose of LEED (Leadership in Energy and Environmental Design) is to create environmentally conscious and energy- efficient buildings.  All newly constructed or substantially renovated school buildings that are state funded must achieve a minimum of Silver certification in the U. S. Green Building Council’s LEED-school rating system with emphasis in energy conservation.  The new building and construction practices addressed the Silver certification requirements.

Roof monitors provide daylight to the gym and the media center. Both wings are oriented to face north and south in order to use daylight-providing windows.  Roofing material is white to provide a solar reflectance index (SRI) of approximately 98.  The roof is insulated with a total of R-25; most walls are insulated to a total of R-12.

School board members and administrators were quoted and agreed, “It’s good to have all of our buildings here on the same campus, great for teacher interaction and staff interaction, and great for our students and parents. The campus here is beautiful.”

Wastren Advantage dedicates new headquarters built by Geiger Brothers

WAI Exterior

Officers and staff of Wastren Advantage, Inc. (WAI) formally dedicated the company’s new office building near Piketon on May 18, 2011, following a Geiger Brothers fast-track construction effort that spanned less than six months from groundbreaking to readiness for occupancy. The visually stunning and extremely functional energy efficient corporate office building rose quickly to house about 50 core WAI executives and staff.

Geiger Brothers began site preparation in late November 2010 on Shyville Road just north of the Pike County (Ohio) uranium enrichment complex and near the OSU South Centers.

Geiger Brothers began clearing and grading work as design continued. Completion requirements were aggressive due to WAI commitments.  January was not an ideal time of year to start foundations, but Geiger Brothers was able to come out of the ground and get enclosure by using lean construction scheduling methodology and tightly controlling milestones while dovetailing self-performed work with managed subcontracts.

In an effort to keep the project moving in order to meet WAI’s time frame for being fully functional and moving staff in place, Geiger Brothers’ constructability review changed the structural steel primer requirements to AISC allowable finishes in a concealed space, modified the HVAC equipment and controls for a simpler integrated approach, and changed many of the exterior site features to allow for better drainage solutions on this beautiful wooded site.

The 11,000-square-feet contemporary corporate office building features multiple and flexible conference rooms; large, open and expandable work areas; and a centralized core area for building services and common spaces.

The exterior has vertical metal siding panels, cement fiberboard panels and some masonry veneer with a standing seam metal roof. The building meets sustainable design standards and features rain garden storm water control, natural lighting, a high efficiency HVAC system, low VOC finishes and the use of recycled materials.

Geiger Brothers received accolades from WAI and the project architect for being able to meet a demanding schedule while safely performing the work in a quality and cost-efficient manner.

Geiger Brothers has key role in building dry air and nitrogen complex

Dry Air Plant Steel

Under contract to CDM Smith, Inc., and in doing “fast-track” construction, Geiger Brothers recently was responsible for pipe support and pipe spool fabrication and installation, concrete pours, earthwork, and underground system installations for new facilities on the U. S. Department of Energy’s (DOE) reservation in Pike County, Ohio.

The design-build contract for the $6.2 million X-670 Dry Air Plant, X-670A Cooling Tower and X-675 Nitrogen Station complex was completed within less than four months. The fast-track was required to move functionality of existing plant air and nitrogen systems from one of the large site uranium enrichment process buildings to enable DOE turnover of the building to the site decontamination and decommissioning (D&D) contractor.

To meet the deadlines Geiger Brothers used Primavera P6 CPM Scheduling software and lean construction techniques, and placed an extraordinary effort on pre-fabrication of components in its shop at Jackson, just 30 minutes from the project site. Geiger Brothers implemented just-in-time delivery of fabricated plumbing, piping and HVAC components working multiple shifts in a 24/7 environment to complete and commission project systems.

Dry Air Plant Night Pours

More than 4,800 code ASME B31.3 Process Piping and B31.1 Power Piping welds were completed for the air, cooling water, nitrogen, steam, natural gas, condensate and boiler blowdown and auxiliary system piping.

Geiger Brothers and designers from CDM Smith utilized virtual and BIM techniques to coordinate the placement of equipment, vessels and heavy piping and electrical components within the building structure.

More than two miles of 18-inch aboveground cooling water lines and structural supports and bridges previously had been installed to link the new dry air plant compressors and nitrogen plant from throughout the DOE reservation.

08-01-10 AG Piping

On behalf of the United States Enrichment Corporation’s Government Services Division, Geiger Brothers has completed work under an accelerated contract to install piping and supports for alternate route cooling water supply and return at the U. S. Department of Energy’s former gaseous diffusion uranium enrichment plant in Pike County, Ohio.

The cooling water system configuration change involved the plant’s X-300 central control facility and X-710 laboratory building and included routing for tie-in to a new dry air plant, cooling towers and nitrogen tank farm that are under construction.

Geiger Brothers provided materials, labor, equipment and supervision to install and test the new tower cooling water supply and return piping for the water cooled chillers in the X-300 and X-710 facilities.

Concrete foundations along with some fabrication of new and modification of existing pipe bents were required. The project involved below grade isolations, installations and the connections to existing recirculating cooling water (RCW) piping.  The contract included line routing to the area of the future cooling tower for the new dry air plant, for which Geiger Brothers has design and construction responsibility under contract to CDM Smith, Inc.

The pipe varied in sizes from 6 to 18 inches. To complete the project, Geiger Brothers painted all new pipe and bents and those areas of existing bents that had been modified.

Geiger Brothers completes rehabilitation of three Jackson County truss bridges

Geiger Brothers has completed renovation of three steel truss bridges under contract to the Jackson County Engineer. The company removed, rehabilitated and then replaced these bridges after completing truss structural upgrades in its Jackson fabrication shop.

The bridges span Salt Lick Creek on Jackson Township Road 217 (Brohard Road) just west of U. S. Route 35, Symmes Creek on Jimes Emory Road (County Road 49) in Madison Township, and Four Mile Creek on County Road 11 (Four Mile Road) near Franklin Grange Road.

PHOTO GALLERY BELOW

The Jackson County Board of Commissioners, upon recommendation of the Jackson County Engineer, awarded the contract for the rehabilitations. The Engineer noted the bridges were installed in the 1950s and 1960s.  He stated this method of giving new life to older bridges saves funds and that the rehabilitation project will make them last another 50 or 60 years.

Geiger Brothers provided design services in addition to dismantling, removing, rehabilitating and replacing the bridges.

Geiger Brothers removed the existing bridge flooring, dismantled the structures, and then removed and cut each of the four- to six-ton trusses for transport. Structural upgrades were made in the Geiger Brothers Jackson fabrication shop, where welding personnel reinforced truss members and gusset plates and re-joined each truss.  Once repaired, the bridge components were sandblasted and galvanized.

Each bridge was then reconstructed at the sites. Upon re-setting the trusses, construction personnel installed new stringers, floor beams and decking and then applied the asphalt paving to complete the work.
