Interpretation of Nondestructive Integrity Tests Using Artificial Neural Networks
A barrier to more frequent use of nondestructive integrity tests on cast-in-place foundations is the difficulty of interpreting the test results to identify the presence or absence of...
Overflow Elimination Benefits from GIS Based Technology
Elimination of wet weather overflows through the rehabilitation of infiltration and inflow defects requires careful analysis of the collection system. The integration of geographic information...
Deformations About Excavations in Highly Stressed Rock
The central business district of Sydney, New South Wales (NSW), is dominated by the Hawkesbury Sandstone, a Triassic sedimentary formation. Measurements have confirmed the existence of...
Management of Sewer System Rehabilitation for the Overflow Abatement Program in Nashville, Tennessee
To comply with a state order to abate overflows of wastewater from the sanitary sewerage system, the Nashville, Tennessee, Metropolitan Department of Water and Sewerage Services has undertaken...
Television and Scanning Sonar in Seattle Metro's Siphons and Brick Sewers
Comprehensive and often costly investigations are required in order to identify performance deficiencies of the pipeline in sewer systems, particularly when sewers in excess of 48-inch...
Inspection Planning for Surface Fatigue Cracks
A reliability based method for planning of inspections to detect surface fatigue cracks is presented. Cracks are described as semi-elliptical surface cracks. The conditions governing fatigue...
Application of Fracture Mechanics Methodology to Assessment of Weld Defects in Offshore Platforms
This paper demonstrates an application of both deterministic and probabilistic fracture mechanics methods to assess weld defects in an offshore platform. The results of the assessment...
Dynamic Testing to Predict Static Performance of Drilled Shafts Results of FHWA Research
The paper describes the preliminary results of recent research sponsored by the FHWA on predicting by relatively economical dynamic methods, the static capacity and performance of drilled...
Reliability Analysis of Weldings Considering Defects
The welds generally represent the most critical part of large structural systems, i.e. offshore structures. Hence they affect significantly the structural reliability. A realistic model...

Analysis and Rehabilitation of Ambursen Dams
This paper deals with the investigation and analysis of two Ambursen dams located in the upper Midwest. These investigations revealed that the original design contained significant defects,...
Building Commissioning
In order to detect and correct defects in a timely, cost effective manner, HVAC system commissioning has recently been used as part of building construction. Preliminary evidence suggests...
Highway Factors in Truck Wrecks
An examination is presented of highway factors as they interact with driver and vehicle factors in large truck accident causation. Examples of highway defects are discussed along with...
Observations and Experiences of Bulb Turbines
This article gives a short historical review of the introduction, construction and development of bulb turbine plants in Sweden. The article relates some of the experiences of the designers,...
Managing Quality into the Workplace
In February, 1983, the author's organization began a process designed to enhance attitudes about quality in every individual member of the organization. The process requires...
