Cost Assessment of Construction Noise Control
The results of a series of studies have provided noise control engineers with a method to estimate off-site construction noise levels and the cost of reducing these to acceptable levels....
Cost-Effective Design of Practically Vibration-Free High-Technology Facilities
Advanced electro-optical equipment, such as that used in the production of integrated circuits, requires clean environments with extremely limited vibrations. Ground motions, personnel...
Site Selection and Building Design for Minimizing Vibration
Over the last five to ten years, line resolutions required for state-of-the-art semi-conductor wafers have dropped to well below 1 micron. As a result, controlling environmental building...
Lift Bridge looks Like Sculpture
A lift bridge built in 1926 over the U.S. Canal at Kaukauna, Wis. was replaced by a sleek new lift bridge whose sculptured shape encloses all the machinery within welded steel box sections....
Optimizing Computer Aided Planning
Computer aided planning may fail if new or untried computer programs or new equipment is used when time is limited. Eleven leadership skills helped the Utah Projects Office, US Bureau...
Problems in Design of Small Reverse Osmosis Water Purification Systems
Small reverse osmosis water purification systems may be defined as those systems which produce from 100 to 20,000 gallons of water per day. This paper identifies some of the common problem...
Noise and Vibration Measurement
Prediction and Mitigation
The papers included in this publication represent a comprehensive view of three major sources of noise and vibration in our environment: Construction equipment and operations; transportation...
Construction-Induced Dynamic Pressure and Corresponding Impact Factors for Pipelines
The Bureau of Reclamation, U. S. Department of the Interior, conducted a study which measured pressure exerted by construction scrapers on a rigid, buried, instrumented concrete slab....
Streamflow Monitoring with Ultrasonic Recorders
In September 1983, four new streamflow monitoring sites were established in a west Chestnut Ridge catchment at the Oak Ridge National Laboratory. Ultrasonic level/flow recorders were used...
Recent Developments in Hydrologic Instrumentation
The availability of space-age materials and implementation of state-of-the-art electronics is making possible the recent developments of hydrologic instrumentation. Material developments...
The Birmingham, England, Airport Maglev Transit Link
This paper outlines the principal design and operating features of the world's first magnetically-levitated transit link which went into public service at Birmingham Airport...
Project Administration
The paper discusses the vital issues involved for the efficient administration of a construction contract: effective communication, field office staffing, long lead procurement of equipment,...
Simulating Construction Operations by Microcomputer
Field operations on major construction projects involve complex interactions among construction equipment, materials and supplies, skilled craft resources, and technical and administrative...
Soft Ground Tunneling of the Greenbelt Tunnels
Mergentime/Loram's contract for the construction of Section E-1d Greenbelt Route Tunnels includes construction of dual 1,770-foot tunnels in soft ground, a crossover structure,...
Construction of Mt. Baker Ridge Tunnel
Mt. Baker Ridge Tunnel is a large diameter soft ground highway tunnel constructed through sensitive over-consolidated silts and clays. Its large diameter necessitates the construction...
Torsional Simple Shear Apparatus for Drained and Undrained Cyclic Testing
Since a cyclic triaxial compression apparatus was first used to study liquefaction of saturated sandy soil, many different types of cyclic shear devices have been used to investigate drained...
Small Strain Measurements Using Triaxial Apparatus
This paper presents a detailed testing methodology which can be used to determine the cyclic properties of soils at very small strains using triaxial apparatus. A discussion of specific...
Construction of Foz do Areia Dam
The methods and equipment for the construction of Foz do Areia Dam during 1976-1980 in Brazil are described. Special emphasis is given to the rockfill construction. Foz do Areia was the...
Construction of Concrete Face Rockfill Dams
The Hydro-Electric Commission, Tasmania, Australia has been building concrete face rockfill dams since 1968. Eight dams from 26m to 110m high have been completed, and the highest at 122m...
A Summary of the Seismic Qualification Utilities Group (SQUG) Program
In December of 1980, the Nuclear Regulatory Commission (NRC) initiated Unresolved Safety Issue (USI) A-46 to address the question of the seismic adequacy of equipment in 49 operating nuclear...
