About Tonias Engineers

Formed in 1980 Tonias Engineers has a long history of providing civil engineering and related consulting services to municipalities, developers and state agencies. Tonias Engineers has also demonstrated the ability to work with other design firms on multi-phased projects such as the Combined Sewer Overflow Abatement Program in Rochester, New York, which, amont other tasks, involved the: overall project management, physical and mathematical modeling, coordination and supervision of the geotechnical exploration program, development of hydraulic, structural and seismic design criteria guidelines and standard drawings, preparation of construction specifications, review of the design of the project section designers, conduct of a public participation program, and development of environmental and cultural resources.

Areas of expertise which Tonias Engineers offers its clients includes the following:

LAND PLANNING AND DEVELOPMENT

The planning and development of new communities, industrial sites and commercial developments involve orchestrated effort of various professional disciplines. Members of the Tonias Engineers staff possess the knowledge and experience in the following component disciplines: planning and layout, traffic flow and street design, sanitary sewers, water network design, grading, storm sewer design, surface drainage, and environmental assessment. Longstanding professional relationships exist with such other professionals as architects, landscape architects, mechanical and electrical engineers, surveyors and economists. Tonias Engineers' computer capabilities are ideally suited in the design of geometric layout and utility, storm, sanitary and water design phases of the the project.

STRUCTURAL ENGINEERING

The staff of Tonias Engineers has planned, designed and supervised the construction of many diversified types of structures including bridges, rock and soft-ground tunnels, dams, hydraulic structures, industrial buildings, sewer and water treatment plants, pumping stations, office buildings, shopping centers, building rehabilitation projects and residential and multiple housing.

GEOTECHNICAL ENGINEERING

The geotechnical division of the firm provides services for the development of subsurface exploratory programs, the analysis and evaluation of soil and rock data, the determination and probabilistic evaluation of earth retaining structures and soil-rock foundation systems, the analysis of soil for settlement predictability, the development of criteria for the design of rock and soft-ground tunnels, the analysis of soil dynamics and seismic engineering, and reliability and risk analysis relating to geotechnical engineering.

TRANSPORTATION ENGINEERING

Members of the staff of Tonias Engineers have participated in and/or directed the planning design and construction inspection of expressways, arterials and streets in New York, Pennsylvania and Ohio. The experience includes: route location and alignment (horizontal and vertical) design, interchange (including multi-levels) design, highway drainage, earthwork, pavement, traffic control, parking layout, construction cost estimates and construction stakeout, inspection and material testing.

MUNICIPAL ENGINEERING

The staff of Tonias Engineers through many years of experience have directed and/or designed numerous facilities within such urbanized communities as Rochester, New York, Hornell, New York, Columbus, Ohio and Syracuse, New York. Projects include the study, design, construction and/or repair of streets, water supply and transmission, solid waste management, storm, sanitary and combined sewers, recreational areas and other facilities necessary for the healthy and expedient function of the communities.

WATER POLLUTION CONTROL

Due to the national emphasis on water quality and elimination of point-source pollution, members of Tonias Engineers have been engaged in a wide range of study, design and construction inspection services on intercepting sewers, collection systems, storage and conveyance tunnels, pump stations and holding tanks. Extensive knowledge and development of computer models have been employed by Tonias Engineers in such tasks as hydraulic transients, infiltration-inflow analysis, combined sewer and stormwater management, sewer evaluation, computer operated gate control and sewer system design.

FLOOD CONTROL

The staff of Tonias Engineers has been involved in the three basic aspects of flood related projects: planning, design and construction, and flood effects and evaluation. Its experience includes such types of projects:

• Comprehensive flood protection master planning for urban and suburban watersheds.
• Inspection, design and construction of dams (concrete and earthfill), levees, retention and detention basins, holding tanks and overflow facilities in areas of combined storm and sanitary sewerage systems.
• Flood insurance studies.
• Study of the cause, evaluation of the results and recommendations for mitigation of floods.
• Determination of capacity rating curves for gated and other hydraulic control situations.

These projects involved complex hydrologic and hydraulic control parameters and necessitated the extensive employment of mathematical models. Computer applications for drainage calculations and simulation of watershed behavior, river flow through varied channel and overbank conditions and bridge restrictions and sewer network system flow have been developed and/or used by Tonias Engineers staff members.
