Fay Engineering Services is a family owned business conceived in 1978. Since then, it has provided high quality, personalized, cost effective engineering solutions to dam safety concerns.
Fay Engineering Services' Mission Fay Engineering Services (FES) provides high quality, cost effective and personalized engineering solutions to dam design and dam safety issues. As dam engineers, Fay Engineering Services provides the unique experience, engineering and craftsmanship to specify unique, cost effective repairs to small and moderate size, low to intermediate hazard dam rehabilitation projects in the northeast.

Company ProfileFay Engineering Services (FES) was conceived in 1978 in order to provide professional design and construction services to the water resources community. It is a closely held company which allows personal participation and supervision by its principals. FES has been involved in all phases and aspects of the dam rehabilitation business. FES has seasoned, professional personnel and registered professional engineers on its staff. FES has its main occupation in the design and repair of new and existing dams, canals, head gates, waste gates and associated equipment. FES has completed the inspection of 60 dams for the Dam Safety Division, Commonwealth of Massachusetts. William K. Fay is authorized to perform Part 12 inspections for the Federal Energy Regulatory Commission (FERC). FES has the ability to react quickly and to bring extensive knowledge and manpower to emergency situations.
An articulated boring rig is taking cores at PHI Upper Dam. The impoundment has been drained. The recovered cores were utilized to locate the heel of the dam and the cohesive strength of the dam/rock interface mortar. FES specializes in conceptual designs, hydrologic and hydraulic analyses, stability analyses, detailed design and specifications, project management, field supervision of repairs, slope stabilization, structural analyses and design of gates and outlet works, feasibility studies, Federal, State and local licensing, flow measurement (current meters, hot wire anemometry, pitot static tubes, weigh tanks, Winter Kennedy, dye dilution, pressure differential and doppler sonic methods), project management, field supervision of repairs, hydraulic transient analyses, inspections and bank "due diligence" studies
Thorndike Upper Dam, Gatehouse Repairs. We designed and constructed a new gatehouse foundation that had been undermined. Luke Wright is replacing one of the mud sills. FES' engineers have in-depth knowledge of the following computer programs and software employed in dam analysis: REAME (Rotational Equilibrium Analysis of Multilayered Embankments), SWASE (Sliding Wedge Analysis of Sloped Embankments), HEC-1 and TR-20 (hydrologic programs), HEC-2 (for water surface profiles), HEC-5 (for reservoir routing), STABGM (for embankments containing tension cracks) WHAMO (CORPS program for hydraulic transients) and BOSS dambreak (for modeling catastrophic dam failures). Equipment includes desktop and laptop computers, Berger 2011 optical transit, Teledyne Gurley revolving cup velocity meter with electronic counter/averager (for low flow studies to satisfy fish agencies and for rough, 2% turbine efficiency testing), Ashcroft dead weight tester, precision mirrored Bourdon test gauges and water testing laboratory. Mr. Fay has been approved by the following agencies to inspect and design dams: Massachusetts Department of Environmental Protection, Dam Safety Section (Contact: Mr. William Salomaa, Director, 1-617-626-1410).
Brookside Dam. New timber flood gates being installed. Note top of new headgate at upper right An Obermeyer automatic crestgate will be installed as part of an MTC financed project. Dave Hobbs is fabricating gate slides on the spillway crest.
Brookside Station. New, white oak, headgate-bulkhead covering former penstock opening. FES has prepared many documents for the Federal Energy Regulatory Commission including license applications, calculations, plans, specifications, emergency action plans, dam break analyses and stability analyses. Mr. Fay is a charter member of the New England Association for Dam Safety and is a member of the ASCE and ASME. He is professionally registered in Massachusetts, Vermont, New Hampshire and New York.
Timber slide gate replacement. Wallum State Park Dam, Douglas, MA. Bill Fay and Dave Hobbs (standing on the dam) are installing the gate.
Spillway Breach, Badger Pond Dam A 10,000 pound, excavator mounted, rock hammer removing a 12 foot tall by 45 foot width section of the spillway.
Spillway repairs at Sebec Lake, Maine. We placed large diameter riprap and flowed concrete between the stones to repair a washout. Ken Smith is supervising the concrete pumper and repair crew.
Sinkhole repairs, Golden Pond Hydro, Ashland, N.H.
Pouring the new spillways at Mill Road in Boylston. Note the duplication of stop log slots in the walls of the flumes. This feature was added so the stop logs could be replaced without draining the pond.
Replacing the timber bascule gates at Collins Dam, Wilbraham, MA. The timbers have been removed. Note the gin pole (left of center) used to remove the old wood with a pulley and catenary system.
Collins Dam with newly replaced flashboards. Note freshly poured concrete to stabilize ripraped tumbling apron.
Repairs to the spillway at Sebec Lake Dam. We jackhammered out and filled in with Sika Pro 123 plus over 400 linear feet of cracks.
Insitu roller gate repair at Sebec Lake Dam. The roller was completely missing and the side channel was damaged. We made a new roller, axle and special side plates.We cut out the damaged steel and fitted in the new roller, axle and plates. We have finished attaching the outside plate and are ready to fit and weld the inside plate. This insitu process saved the owner 8 weeks of down time and twenty thousand dollars of crane and rigging expenses. Remains of the sluice gate at Tannery Pond, Winchendon, MA.
Newly constructed sluice gate at Tannery Pond in Winchendon. The temporary stop logs, to prevent the lake from draining, can be seen in the lower background. We are just finishing the installation of the oak gate guides. Please see the attached link to the Picasa photo album of the complete project.
