AEG’s Scope of services included:
Concrete Core:
Perform ten concrete cores; four cores within the paver walkway and six cores within the building. One core from each of the five locations will be tested for compressive strength test and petrographic analysis per ASTM C-42 & C-856.
R-meter was used to locate rebar before coring.
The areas of cores were prepared; this included removing pavers and providing scaffolding.
Petrographic analysis includes water soluble chloride content; carbonation water/cement ratio, air entrainment etc. were conducted.
Water penetration Testing and Infrared Thermography:
Testing was done using spray racks calibrated to the specifications of ASTM E1105. The amount of water delivered by the spray racks is 5 gal per square foot per hour, correlating to an 8 inch per hour rain event. Stone block were removed prior to performing the test.
Water infiltration was observed during the test at several locations in the ceiling slab and at exterior wall along the west elevation of tower.
Thermal images were taken using a FLIR ThermCAM B2 infrared camera to aid in detection of water leakage and moisture presence.
Results were assessed and a findings report was prepared including images.
Soil Testing:
Soil testing to determine ground water level & sol properties.

Structural Assessment of Stairs at DSNY Facility in Queens, NY
AEG was retained by NYC Department of Sanitation for “as-needed” professional services at various locations in the five boroughs of New York (2012 – 2014). Various assignments were undertaken by AEG under this “as needed” agreement for NYC Sanitation.
This assignment included inspection and assessment of all the 12 existing aluminum staircases in the Central Repair Shop & Garage. Over time there have been many incidents involving broken stair components and subsequent repairs.
AEG undertook a detailed assessment of each component and the appropriate replacement of components rather than completely replacing the entire staircase.
AEG’s SCOPE OF SERVICES:
1. Condition assessment of existing stairs.
2. Code review.
3. Investigate the problems and provide recommendation to fix these problems.
Structural Assessment of Flood (SANDY) Damaged 297 West Street, New York, NY
AEG was retained by NYC Department of Sanitation to undertake condition assessment of 297 West Street, New York, NY due to flood damage by storm Sandy. The building was flooded by sea water from Hudson River on the west side. The building had to be abandoned due to the hazmat contamination and structural damage.
AEG undertook condition assessment of all building systems and components including architectural; structural; electrical; mechanical; plumbing; fire and environmental damage.
Historic Bethaney Building Condition Assessment, 40 Sommerstown Road, Ossining NY (Architectural, Structural & MEP Inspection)
AEG undertook the condition assessments of this historic building at 40 Sommerstown Road, Ossining NY for Bethany Arts Community.
Assessment included, site areas, building envelope (exterior), interior. Site inspection includes paved and unpaved surfaces, landscape, site drainage, lighting, street furniture, etc. Building inspections include all exterior and interior components such as façade, roof, stairs, structure, doors, windows and finishes, electrical, mechanical, plumbing and fire safety systems. Inspections for electrical systems include building site and exterior security lighting; communication and security systems including CCTV, intrusion alarms, remote enunciators, panic switches, ultrasonic sensors, fire alarm and emergency lighting systems.
Inspection is conducted by a four-member team comprising an architect, and structural, electrical and mechanical engineers. Inspection reports contain building templates (plan), elevation references, and photographs of typical deficiencies. Any hazardous conditions or structural deficiencies that were identified were reported immediately to client. Building components were rated on a scale of 1 to 5, and were given an estimated “remaining useful life” (in years) by the inspectors. Component deficiencies were identified and quantified. Recommendations to repair or replace were made, along with a recommended time period in which to repair/replace each component.
The data collected was then analyzed, and priority component repairs and replacements were identified for each asset. These priority components were then allocated a unit price to arrive at a budget plan for restoring and maintaining this asset in state of good repair.

Southridge Hills Development at South Brunswick, NJ
Estimated Fee: $24,000
AEG (Architecture & Engineering Group, P.C.) conducted inspection of the asphalt pavement at Southridge Hills (SRH) Development in South Brunswick New Jersey during April 2008. There is approximately 325,000 SF asphalt pavement in the development which includes Southridge Hills Drive, Bard Drive (north & south) and the parking courts. The scope of this inspection was to observe existing condition of asphalt pavement, consider options for repair/replacement and present the findings to the SRH Board with cost estimate of each option.
Asphalt pavement of all parking courts and roads within the development was in fair to poor or in poor condition. Asphalt surface had alligator, random cracks (fine & wide), potholes and completely deteriorated asphalt wearing course at a few intersections. Overall the condition of asphalt was worst at intersections and in parking courts. Generally the grade/slop of asphalt was good, we did not observe any major water ponding, except for areas where asphalt wearing course was deteriorated.
The entire asphalt surface generally needs a mop coat of sealer to seal fine cracks. All open/wide cracks need to be filled with crack filler to prevent condition from worsening due to freeze/thaw cycle and continued use. Potholes and deteriorated asphalt wearing course needs resurfacing after saw-cutting & removal of 1 ½” asphalt overlay.
AEG provided two options with cost estimates. AEG recommended that the entire asphalt surface be milled, remove and dispose the 1 ½” to 2” overlay (wearing course) and new asphalt overlay be installed. It was recommended that seal coating be applied two (2) years after the asphalt pavement has been replaced to maintain the surface and prevent early deterioration of asphalt pavement.
Southridge Hills Development at South Brunswick, NJ
Estimated Fee: $42,000
AEG (Architecture & Engineering Group, P.C.) conducted inspection of all (208) wood decks at Southridge Hills (SRH) Development in South Brunswick, New Jersey during March & April of 2008. Decks were of three different shapes & sizes. All decks had an upper and lower deck. Both levels serve as entrance to the residential unit. The scope of this inspection was to document deficiencies requiring repairs for which the SRH association/board is responsible.
Decks consisted of wood deck boards (2”x6”) supported on 2- 2”x8” wood joist @ 16” o.c. or 24” o.c. Floor joists are supported on 2-2”x10” wood beams at both ends. Wood beams on one end were anchored to the foundation wall of the building and the other end was supported on 4”x4” wood posts spaced @ 7’-0” ± apart. Wood posts were supported on 12” diameter isolated pier concrete footings.
All upper decks were tilting forward/down from the building due to probable settlement of the isolated concrete footing. It appeared that the footing settlement occurred in the past but there was no evidence of continued settlement and decks were structurally stable.
