USDA Natural Resources Conservation Service A/E Services for Conservation Practices

 

D&K provided survey services over a 5-year period in support of project work assignments issued under the NRCS Vermont and New Hampshire retainer contracts. Design services included civil engineering for roofed barnyard structures, streambank restorations, water supply ponds, and concrete waste storage facilities for agricultural facilities throughout Vermont and New Hampshire.

D&K survey services associated with these assignments consisted of: field topographic and bathymetric surveys, boundary survey, deed research and property plats, base map preparation, setting monuments and witness posts, three-dimensional ground terrain models, and horizontal and vertical controls. Parcels ranged from one to three acres. Several project sites involved difficult terrain. Work was completed following NRCS Survey Standards and guidelines established under the Wetland Reserve Program (WRP) and EQIP Program. Required coordination with the local NRCS WRP Program Manager/Biologist.

USDA Forest Service White Mountain National Forest South Gale Road and Bridges Reconstruction Survey

 

DuBois & King was the prime consultant for a design/build project to provide engineering and construction services for the reconstruction of South Gale Road and of four bridges. A storm event damaged sections of the roadway, removing surfacing and cutting into the subgrade and ditch, and damaging four road bridges. The roadway design included restoring the roadway sections, providing slope stability, improving drainage, and replacing aggregate surfacing and some asphalt surfacing. The roadway construction included embankment construction, drainage excavation, and installation of a culvert and paved aprons to four bridges.

DuBois & King performed field survey for an approximate .5 mile length of Forest Service highway and four stream crossings, base mapping, and utility coordination; secured geotechnical borings; identified wetlands; prepared permit applications and preliminary and final design plans in state plane coordinates; and provided construction phase services. During construction, D&K surveyors returned to the field to stake out the bridge locations and re-establish survey control in the field for the contractor.

USDA Forest Service White Mountain National Forest Beaver Pond Dam Design-Build

 

Survey and base mapping services for a design-build project to rehabilitate the Beaver Pond Dam in the White Mountains of New Hampshire. The dam was in poor condition with a failing concrete spillway, seeping earth embankment, and an inoperable low-level outlet. The Forest Service required NHDES dam safety regulations be followed throughout design and construction. D&K developed design measures to minimize environmental impacts caused by construction activities, including mitigating sediment release.

The dam, surrounding embankments, and watersheds were surveyed utilizing GPS controls. Base plans were developed in state plane coordinates for design. All work was conducted in accordance with the US Forest Service Survey Standards & Specifications.

USDA Forest Service Kiasutha Recreational Area

 

Inspection, evaluation, and design of improvements to the Kiasutha Recreational Area located in the Allegheny National Forest. Performed inspections of the project site to make improvements for new campsite locations, orientation, accessibility, slopes and grading, drainage, and utility connections. Services included:

Field Survey/Data Collection. Survey and inventory/base maps.

Roadway/Transportation. Design of cul-de-sacs, new parking areas, new roadway sections, replacement of culverts, new drainage ditches, and riprap ditch lining.

Campsite Improvements. Design for improvements and construction of new campsites.

New Campground Loop. Design for new campsite loop including 20 campsites.

Site Design. Design of amphitheater, two playground areas, and accessible pathways.

Facility Improvements. Water, electric, and sewer upgrade design including shower/restroom buildings, and picnic pavilions.

Water System Improvements. Design for new waterlines and replacement of existing waterlines including new valves, stops, and water system drains.

Sewer Systems. Design for new and rehabilitation of sewer lines and manholes, correct infiltration and inflow, and new hookups for campsites.

Electrical System Improvements. Upgrade and design of new electrical services and equipment, and increased capacity upgrades.

US Department of Labor Job Corps Center

 

Civil/site engineering for design and construction phase services for the Department of Labor’s 1,600,000 sf Job Corps Center. The campus is located on a steep, wooded 20-acre site and consists of two dormitories, an educational building, a cafeteria, an administration building, a welcome center, a recreational building, parking, roadways, and walkways.

Complete survey and civil/site services included permitting and design for utilities, access roadways, sidewalks, exterior lighting, retaining structures, and landscape architecture. Site design for this fast-track project was completed in 10 months. The total project cost is $34 million.

The D&K survey crew tied into existing boundary corners and conducted topographic survey to obtain 1 ft contour intervals on this 20 acre wooded parcel. Survey was developed into a 3D model base plan to assist the design team performing visual concept design and permitting.
