Glitches in Flitch Beam Design
Wiesenfeld proposes a set of design criteria for flitch beams. These beams, in which wood and steel sections are bolted together to act as a single structural unit, are currently covered...
Screaming Structures
As any designer of roller coasters will tell you, civil engineering principles put the thrills and screams into roller coasters. There are two basic differences between roller coaster...
Contractability?Recent Concepts in Contracting
Owners are customizing project delivery systems by uniquely aligning service agreements and construction contracts. Seeking more productive ways to construct facilities, owners currently...
Highway Project Constructability
Results from on-going research into highway project constructibility are discussed. Research objectives and methods are outlined. Prime constructibility objectives are presented along...
Subcontractors' Concerns Regarding Productivity
This study suggests that smaller contractors, many of whom operate as sub-contractors, are less interested than larger firms in taking an active part in identifying, funding, and conducting...
A Model for Construction Quality and Productivity
A set of necessary and sufficient conditions for construction quality is developed. Numerical simulations are then performed to evaluate the effectiveness of various quality improvement...
The Use of SIPS as a Productivity Improvement Tool
SIPS, an acronym for short interval production schedule, applies many of the earlier scheduling techniques to individual operations that are key or pacesetter operations on a project....
Building Onto History
In a single design/build/renovation project, an Oklahoma City AE firm acquired new offices, provided new life for an abandoned historic church building and spearheaded redevelopment of...
Classic Wood Structures
Wood has been used in a wide range of structural applications. When properly maintained, these structures can have a useful life from 50 years to several centuries. Thirty-seven unusual...
Rebuild of Ten Mile Intake Flume Structure for Electron Hydropower Project
In 1984 the Puget Sound Power and Light Company began a rebuild of what is popularly referred to as the 'world's crookedest railroad. ' The 'railroad'...
Osoyoos Lake Control Structure
The new Osoyoos Lake Control Structure has been built on the Okanogan River at Oroville, Wa. The site is about 2 miles downstream from the outlet of Osoyoos Lake, and about 9 miles south...
Load-Sharing and Reliability of Wood Systems
A methodology for the study of reliability of light-frame wood structural systems is presented. Reliability levels associated with the bending strength limit state of such systems are...
Lifetime Reliability of Wood Structural Systems
A model to predict ultimate capacity reliability of wood systems is developed. The model is analogous to Markov cumulative damage models. System ultimate capacity is defined as failure...
An Investigation of the Supports of a Water Main
Two 48 inch (1. 22 m) diameter cast iron pipes constructed 50 to 70 years ago form a major part of the potable water transmission system of Atlantic City. For the most part of their length,...
Construction's Critical Condition
The United States construction industry is experiencing a decline due mainly to the drop in productivity. Even though tools have improved and labor costs have remained in relative parity,...
Load and Resistance Factor Design for Engineered Wood Construction
A Pre-Standard Report
The information contained in this pre-standard report is intended to provide guidance to writers of a load and resistance factor design (LRFD) specification for engineered wood construction....
A Clean Up in Slow Motion
Eight years have passed since contamination was first discovered at the Valley Wood Preserving plant in Turlock, Calif. Though severe chromium contamination continues to travel toward...
Port of Eastport, Maine: A Growing Breakbulk Cargo Port (
The Port of Eastport accommodated over 90,000 tons of international waterborne trade in 1986. In 1980, this trade-related port operation was non-existent. A Cargo Facility Economic and...
Establishing Native Plant Communities on a Coastal Landfill, Berkeley, California
Three native coastal plant communities were successfully established in a park created on a landfill site on San Francisco Bay: coastal strand, coastal scrub, and prairie grassland. The...
Caribbean Coastal Marine Productivity (CARICOMP): A Regional Laboratory Network
The CARICOMP (Caribbean Coastal Marine Productivity) project began with a workshop in 1982. Marine scientists from 12 Caribbean nations gathered to consider the factors controlling the...
