Cofferdam Rip-Rap Protection for the New Esna Barrage
A 1:60 undistorted mobile bed model of the Nile River in the vicinity of Esna Barrage was constructed at the Hydraulics and Sediment Research Institute to test rip-rap protection of the...
Calibration of Beni-Mazar Movable Bed Model
A sand-bed model representing a reach of the Nile River was constructed to study alternative solutions to maintaining the navigation channel. Flume tests were carried out first to determine...
Numerical Modeling of Proposed Channel Designs (J. F. Baldwin III), California
Ship simulator studies of proposed improvements to navigable waterways are a very important part of any assessment. The John F. Baldwin Channel (JFB) Project (Phase III) is a ship channel...
Drought-related West Tennessee Channel Bank Failures
Massive bank failures occurred in 1988 along a 14-kilometer reach of the lower Obion River channel in Dyer County, West Tennessee where the river flows through an abandoned Mississippi...
Fluvial Recharge of Sand Mining Pit
Accuracy in modeling fluvial processes becomes increasingly important as development occurs along waterways. The FLUVIAL-12 (1, 2) model is used to simulate the recharge of sand mining...
Development of Crop Coefficients Using Lysimeters
A long term record of evapotranspiration by grass as measured with the large weighing lysimeter at the University of California at Davis provided an excellent background for the initiation...

Temporary Facilities?Making It Happen, Organization and Logistics
As construction projects become larger, more complex and are constructed both faster and under more adverse conditions--the use of temporary facilities is more prevalent. Temporary facilities...
CPM Techniques for Claims Avoidance and Preparation
Virtually all major construction claims consist of some aspects of delay, disruption or acceleration. Since all of the foregoing relate directly to the timing and sequencing of the project...
Planning and Organization to Control Liabilities and Insurance Cost
The liabilities and insurance cost associated with construction projects can be considerable. Activities that are performed which carry extensive liability exposures with limited controls...
The Benefits of U.K. Guidance for Temporary Works
In British contracts the Contractor is responsible for the design and execution of temporary works unless the Design Engineer or the Client expressly instruct how the work is to be undertaken...
Legal Principles and Theories
Legal issues are intertwined with all aspects of the technical considerations relating to temporary structures. This paper presents an introduction to the legal theories which relate to...
Current Legal Issues Impacting Temporary Works in Construction
There are two evolving areas of legal concern to the engineer and contractor involved in any aspect of temporary construction. The interpretation and application of the Occupational Safety...
Liabilities in Temporary Structures Failures?Representative Case Histories
Eight case studies involving construction accidents caused by failure of temporary structures are presented. These studies illustrate the oftentimes unintended consequence of utilizing...
Liability Insurance Coverages for Designers of Temporary Structures
A recent survey completed by the American Consulting Engineers Counsel (ACEC) indicates that in 1990 approximately 40 claims occurred per 100 firms. There also is an indication that claims...
Safety Analysis of Handset Wood Slab Formworks
A reliability index is calculated for flexural strength of a handset wood slab formwork system. Load and resistance models are based on a survey of construction loads and wood test data...
Limit States Design of Wooden Formwork for Concrete Walls
Load and resistance factors are developed for ultimate limit states design of wooden formwork components for concrete walls when the lateral concrete pressures are computed using the ACI...
FHWA'S Bridge Temporary Works Research Program
The Federal Highway Administration (FHWA) has developed a research program to address bridge falsework design and construction. This resulted from the collapse of the Route 198 bridge...
Development of Standards for Slipform & Jumpform Works
Review of past work indicates substantial effort has been made to publish construction standards and guidelines for slipforms but published material pertaining to jumpforms is scarce....
