Managing Problems Associated with Using Computer Programs
Everyone says they want to use computers. Yet, there are still some people who avoid using computers whenever they can. Also, some managers still resist using the latest computer technology....

Managing Managers
Early in their careers engineers usually begin to manage small groups of people. To learn the necessary skills of management young engineers often imitate their supervisors. This approach...

Managing Work
Managers often ask engineers to do more work without providing more resources to support the requests. In response, engineers typically counter that they need more resources (time, money,...

Technician or Manager
After working awhile many engineers want to go back to school, or learn new skills. There are two reasons for this. One is that we perceive training as the key to advancement. Another...

Improving Stone Placement Specifications
Thorough preparation of stone placement specifications can go a long way toward keeping projects on track. But developing well-prepared placement specifications is not easy. It requires...

The Assessment of Armourstone for Shoreline Protection
To protect shorelines from erosion, Ontario Hydro is using armourstone at various Generating Stations along the perimeter of the Great Lakes. Armourstone is carefully evaluated prior to...

An Example of Rubble Mound Construction Procedures
The Gold Coast of Queensland, Australia, is in an exposed coastal zone that is now suffering from major problems with both the availability of suitable large rubble armour and its durability...

Pricing Armor Rock for Rubble Mound Breakwaters
The pricing of armor rock by breakwater contractors is an inexact exercise. Each breakwater project is so site specific that standard costing methods are difficult to apply. The wide range...

Quarry Techniques for Dimensional Breakwater Stone
On the Texas Gulf Coast, there has evolved a unique design for breakwater and jetty structures. The Galveston District of the U.S. Army Corps of Engineers, the designer of these structures,...

Quarry Inspection: A Geological Perspective
The need to use durable rock in building projects is becoming more critical as the costs of labor and materials rise. The Steering Committee of the 1991 Quarried Rock For Rubble Mound...

The Durability of Rubble Mound Armour in Service ? A Case Study
Over the past decade, the ongoing monitoring of Gold Coast rubble mound structures in service has demonstrated a serious loss of durability over a period of time in the rock units after...

RCC for Rehabilitation of Dams in the USA-An Overview
The use of roller-compacted concrete (RCC) has rapidly become a powerful new tool in the USA for engineers involved with the rehabilitation of existing dams. Starting in 1980, RCC has...

Design and Proposed Construction Techniques for Pangue Dam
The paper describes the site conditions, design and proposed construction methods for the 115 m high Pangue Dam, Chile's first RCC dam. Trial mix design work and test embankments...

The Construction of New Victoria Dam, Australia
The paper discusses various aspects of the construction of the New Victoria Dam, a 52 m high, high-paste content RCC dam constructed near Perth, Western Australia. The mix design and its...

Design of Miel II?A High RCC Dam
Miel II Dam is a 141 m high RCC structure designed for the tropical mountains of central Columbia. Interesting features are its height (considerably higher than any existing RCC Dam),...

Roller Compacted Concrete Arch/Gravity Dams?South African Experience
The paper traces the development of roller compacted concrete (RCC) dams in South Africa, and in particular the application to arch/gravity dams. The Department of Water Affairs and Forestry...

The Design and Construction of Shuikou Project RCC Diversion Wall
Shuikou Hydroelectric Project, currently under construction on the Minjiang River in the People's Republic of China is a concrete gravity dam having a maximum height of 101...

A Review of Design Criteria for High RCC Dams
The 1980s could be considered to be the decade during which roller-compacted concrete dams came of age. This economic method of construction is sufficiently proven that very large dams...

Performance of Upper Stillwater Dam
Upper Stillwater Dam was constructed with roller compacted concrete (RCC) and horizontally slipformed facing. This unique construction method for a concrete gravity dam included no contraction...
