Technical Aspects of Metric Construction
The Water and Power Resources Service, formerly the Bureau of Reclamation, has begun construction of a number of major projects using SI metric units. Technical aspects of the design and construction activities...

Construction Operation and Microcomputers
The availability of small reasonably priced computers—micro-computers—has made computer based techniques and management control accessible for the analysis of construction processes. A microcomputer implementation...

Scheduling: Effective Methods and Techniques
Network planning and analysis (CPM) is a proven means to outline the many activities to be performed and to investigate the feasibility of a given construction project. Commencing with a Master Project...

Planning, Scheduling, and Communicating on Crew Productivity
Construction project planning and scheduling along with communication of the plan have major impact on the productivity of field crews. Though the size of the impact is practically impossible to document,...

Underground Transit Station Construction in Japan
Technologies used in Japan for constructing underground stations for heavy-rail urban rapid transit systems are described. Two example projects have been chosen that illustrate different approaches which...

Aggregate Gradings for Nuclear Concrete
Evaluation of concrete shows that segregation, inherent in rehandling of coarse aggregate, is significantly reduced in the large mixers used in concrete production. The investigation also shows that relatively...

Compression Overlapping Precedence Networks
A study is presented, which is directed at finding a solution to the problem of compressing networks having overlapping activities. The method involves the use of cost duration charts, network diagrams...

Contract Administration: A Resident Engineer's View
Professional liability related to field work is a major concern of the consulting profession. Field personnel should review the plans and specification in the pre-construction period and systemize the...

Games People Play with Work Sampling
Guidelines and principles are presented for planning and implementing a work sampling program. Principles to be followed include careful planning to fulfill objectives, the need to be responsive to changing...

Modernized Metric System—SI—The American Choice
Americans have played a major role in the development of the new International System of Measurement Units (SI). The world is moving rapidly in the adoption of this modernized metric system. SI is an absolute,...

Managerial Decisions Under Inflation
The problems of managerial decision making under inflation are discussed, and some solutions are offered. The risk of estimating under inflation is explained, and a method to improve the prevailing compensation...

Biomass as Alternative Energy Source
The potential for biomass utilization as a source of fuel, petrochemicals and petroleum-sparing substances is reviewed. The choices for cultivating biomass, utilizing it directly as an energy source, and...

Estimating Underground Power Station Costs
Planners involved in evaluating pumped-storage alternatives found the capital cost of the underground powerstation directly related to the installed capacity. Estimates for three underground powerplant...

Coal-Fired Reference Plants: Project Benefits
It is expected that requirements for new electric generating capacity will necessitate shortened engineering and construction schedules for future coal fired projects. The reference plant approach, as...

Ash Pond Construction to Meet Performance Requirements
The establishment of environmentally acceptable ash disposal reservoirs for a steam electric station is achieved through the design of impervious embankments and foundation cutoffs. Field and laboratory...

Design of Fan Foundations
A design approach for satisfactory and cost effective rotary machine foundations, especially fan foundations, is presented. The often used minimum stiffness criterion for the foundation is replaced by...

Cooling Tower Practice in Germany: State of the Art
A rapid development in design and construction of natural draught cooling towers has taken place in Germany. Research has been concentrated on theory and analysis of shells, on acting forces, especially...

Full-Scale Tests on Ground Anchors in Fine Sand
A series of ground anchors of varying lengths were installed in a medium dense sand, with a veiw to study as many as possible of the variables influencing anchor behaviour and load transfer. The anchor...

Numerical Models for Track Support Structures
Three finite element formulations based on one-, two-, and three-dimensional idealization for analysis of railroad track support structures are presented with major emphasis on the three-dimensional procedure....

Horizontal Stiffness and Damping of Single Piles
Simple expressions are developed for the equivalent horizontal spring and damping coefficients at the top of an end-bearing pile embedded in a uniform linear soil. Beam on elastic foundation (BEF) and...
