"One of Western New York's first "Green

Design" public projects."

Urban Engineers (Urban) was a subconsultant to the

country's premier justice facility design team for the design

of the replacement of Erie County’s Secure Youth

Detention Facility, in Buffalo, NY. Urban provided

structural engineering, all civil/site design, utility design for

the new buildings, and engineering for the demolition of

the existing facility and utilities. Review of several

proposed alternate sites, and recommendations for

increasing the size of the existing site, were also Urban’s

responsibility. The new facility incorporates a school, pod

style resident halls, and a dramatic entrance canopy

designed by Urban.

The 68-bed, detention facility is a state-of-the-art temporary housing for troubled youth. The 67,000-SF project is a

secure building with space for education, counseling, and indoor and outdoor exercise facilities.

The project is one of Western New York's first public projects that introduced the elements of "Green Design" in both the

design and methods and materials of construction. During the site plan review process, Erie County required the

contractor to recycle as much construction and demolition debris as economically feasible. The demolition phase of the

project yielded more than 10,000 tons of recycled material, which saved Erie County taxpayers approximately $130,000

on this phase of the project.

"Replacement of aging infrastructure to

enable base to meet modern day demands."

Urban Engineers (Urban) was retained by the Niagara

Falls Air Reserve Station to study and design a base-wide

water distribution system revitalization.

Urban constructed a hydraulic model of the base using

the WaterCAD software package to simulate available

domestic and fire flows available to locations throughout

the base. Following iterative runs of differing main sizes, ranging from 6-to-18 inches in diameter, a final sizing plan

consisted of approximately 8,000 LF of 12-inch, 10,200 LF of 10-inch, and 11,200 LF of 8-inch diameter pipe. The

resulting fire flow availability is in the range of 2,700-3,000 gpm.

The special needs of the air base included identifying and minimizing impacts to several on-site underground obstacles,

such as petroleum pipelines, communication lines, fiber optic lines, and security measures. To minimize disturbance to

these obstacles, Urban evaluated the possibility of trenchless technology, in addition to corridor alternatives and

contingency planning.

The design incorporated about 55 new hydrants spaced in accordance with military regulations for aircraft facilities.

Additionally, isolation valves were placed at watermain intersections and spaced as per military requirements, and new

water service connections were designed, including service piping up to and within buildings where services are 10 years

or older. All items were designed in accordance with military regulations as well as American Water Works Association

standards. The total estimate to construct the proposed facilities was approximately $1.8 million.

"The demolition was carefully planned and

executed to minimize impacts to an active

hotel and nearby infrastructure, including a

major drainage tunnel."

Urban Engineers (Urban) was retained by the City to

conduct an analysis of the structural condition of a 30-

year-old parking structure and recommend improvements

to refurbish the facility. After reviewing the report and

financial analysis of the alternatives, the City determined

demolition was the best option. The City hired Urban to

design the demolition and replace it with a new surface

lot.

Urban prepared construction drawings and specifications for the demolition of the 1,400-vehicle, 3.5-acre parking

facility. The ramp was constructed of pre-stressed concrete. Demolition activities were carefully planned to minimize

impacts to an active hotel located 10 feet to the south of the building and existing infrastructure, including a major

drainage tunnel located beneath the footprint of the structure.

The new surface lot required survey work, planning, layout, landscape layout, design of storm drainage, and utility

relocation. The design of the surface lot also posed interesting challenges, such as: an 11-foot drop in grade across the

site; the new facility had to be designed to incorporate part of the existing stormwater infrastructure from the ramp; and

the location of the lot lies in the heart of downtown Niagara Falls in proximity to the international bridge, Seneca Niagara

casino, surrounding hotels, and Third Street corridor.

Experiencing growth and an increasing demand for

parking facilities at the Niagara County Community

College Campus, Niagara County hired Urban Engineers

(Urban) to provide the design of a new campus entry and

drop off loop, a new parking lot facility, and a parking lot

expansion.

Urban reviewed historical campus record drawings of existing facilities to understand the conditions and developed a plan

for the proposed improvements in character with the campus facilities.

Urban conducted a traffic analysis of how the facilities would be used and presented the client with alternatives for internal

traffic circulation plans, which defined the appropriate layout and alignment of the new facilities. A stormwater pollution

prevention plan was also assembled for this project to address both temporary and permanent stormwater control

measures.

Urban developed the design plans and schedule to reduce any impact to campus operations.

"......an environmentally-friendly treatment

option for glycol-contaminated stormwater."

Urban Engineers (Urban) designed a new treatment

system to address glycol contamination of stormwater at

Buffalo-Niagara International Airport (BNIA). The system

utilizes an emerging technology of "Stormwater

Wetlands," which are entirely below ground surface

aerated gravel beds. As a subconsultant, Urban was

responsible for providing stormwater analysis/design, civil

design, structural design, and related specifications and

details.

The newly-engineered BNIA wetlands treat glycol-contaminated stormwater runoff and other wastewater during the de-

icing season. In addition, the wetlands treat the stormwater sewers' base flow and rainfall event first flush runoff year

round.

The wetlands consist of four rectilinear wetland cells excavated from an existing open area near the airport's main runway.

At ground level, only a field of wetland grasses is observable, growing from a "dry" mulch surface. The system is designed

to treat up to 0.2 MM gpd of concentrate from the de-icing pads from up to 300,000 gallons of pure propylene glycol

used annually during the average 190-day de-icing season. In addition, the system is designed to treat an average

stormwater flow rate of 1 MM gpd year round. The design also allows for treating a mix containing up to ~2,150 mg

BOD/L during the de-icing season and uses existing underground glycol and stormwater tanks for flow equalization.

Urban Engineers (Urban) was selected to provide

construction management services for the Sullivan County

Transportation Facility, located in southeastern New York,

approximately 90 miles northwest from New York City and

close to Route 17 (Future I-86.)

The new facility was constructed on partially-wooded lands

adjacent to the Sullivan County International Airport. The site encompasses seven acres of land of which five were

developed to provide a 9,000-SF, single-story pre-engineered office and garage building with road access and parking

for 54 vehicles. The building encompasses 3,600-SF of administrative offices, a training room, kitchen, restrooms, upper

level mechanical room, and 5,400-SF of garage space with six pull through bus bays.

The facility is served by a drilled water well, septic system, an underground propane storage tank, forced hot air heat, air

conditioning, and infrared radiant heaters in the garage area. Electrical and communication utilities are located

immediately adjacent to the site along County Rt. 183. Future plans allow for expanding two additional pull through bus

bays, which were postponed due to costs and requirements. Also planned is the addition of a Photo Voltaic Solar Array

system for supplemental electric power, which was not part of these contracts.

"This project utilized a new approach to

concrete pavement repair and was used as a

pilot project."

Urban Engineers (Urban) performed the construction

inspection for the pavement rehabilitation of four miles of

the Niagara section of the NYS Thruway.

This work included full-depth concrete pavement repairs,

partial-depth pavement repairs, dowel bar retrofits, and

diamond grinding. Maintenance and protection of traffic

was important due to the high volume of traffic on the

Thruway.

Urban's staff devised an innovative use of aerial photographs and transparent overlays to produce daily maintenance and

protection of traffic layouts in advance of the work. This allowed them to rapidly adapt to changes in the contractors'

schedule, in addition to promote clear, concise communication between Urban's team and the contractors.

"altered the drainage plan...resulting in

significant savings to the contract."

Urban Engineers of New York, P.C. (Urban) is performing construction inspection services for the New York State Department of Transportation for the reconstruction of Transit Road, US Route 78, in the Towns of Amherst, Cheektowaga, Clarence, and Lancaster. Urban is responsible for providing construction inspection and record keeping services for the more than $28 million reconstruction of Transit Road. The project's objective is to fully reconstruct approximately three kilometers of Transit Road between Main Street and Genesee Street from five to seven lanes. The project operations include installing and/or relocating the underground drainage system, including installing a seven-foot diameter, reinforced concrete pipe to facilitate the drainage of this highly-commercialized area. The project also included installing new waterlines and sanitary sewer facilities, most of which required blasting of rock for excavation purposes. A major concern is the maintenance and protection of traffic. Urban developed complex scenarios to maintain the four lanes of traffic needed to handle the congestion along this critical urban arterial. The new pavement sections include both Portland cement concrete pavement and asphalt cement concrete pavement. During the project, the prime contractor submitted and received approval of an extensive value engineering change proposal, which altered the drainage plan and eliminated a planned box culvert, resulting in significant savings. Urban's team consists of a Chief Inspector, Office Engineer, three Senior Transportation Inspectors, and a Transportation Inspector Trainee.

"This project featured the reconstruction of a

heavily damaged park roadway following an

early season snow storm."

In October of 2006, Western New York was hard hit by a

surprise early season snow storm. Since the leaves had

not yet fully fallen from the trees, thousands of trees lost a

significant portions of their limbs, which created a number

of regional states-of-emergency.

In the emergency cleanup effort, the Town of Tonawanda utilized Lincoln Park as a staging area for temporary storage

and handling of storm debris. The significant use of the road by hundreds of trucks hauling debris resulted in severe

damage to the roadway.

The Town of Tonawanda hired Urban Engineers to complete the design and oversee the construction of a full road

replacement, which was funded in part by Federal Emergency Management (FEMA) monies.

The project included nearly 2,000 feet of roadway, concrete gutters, new storm drainage design, and stabilized roadside

parking areas for park users.

"Demolition of failing structure for site

redevelopment."

Urban Engineers (Urban) was retained by the Seneca

Construction Management Corporation (SCMC) to

prepare design plans for demolishing various structures

on four separate sites owned by the Seneca Nation. The

demolition included the former Salamanca Hospital

Complex with ancillary office and maintenance buildings,

Killbuck School, a commercial masonry building, and a

four-unit, wood-frame residential structure.

Plans were not available for any of the structures to be demolished and, as a result, Urban had to perform extensive

surveys at each site to define site conditions, locate structures, plot utilities, and establish site topography. Urban also

undertook mandated hazardous material and asbestos surveys, analyzed samples taken, and documented the results in a

report for each site. In addition, due to the age and condition of the structures, each one was inspected for structural

integrity to evaluate safe access for asbestos removal and demolition activities. As a result, the main structure at the

Killbuck School site was condemned requiring variances for the asbestos removal and disposal.

Urban then prepared construction drawings and specifications for removing, transporting, and disposing of hazardous

materials, demolitions, utility issues, and site restoration. As directed by the SCMC, all foundations, basement walls, and

floors were totally removed and backfilled with compacted stone to allow for future development. Demolition activities

and site restoration were carefully detailed to minimize impacts on adjacent properties, vehicular/pedestrian traffic, and

drainage patterns .
