Abstract:

SP-90 A collection of 15 papers dealing with concrete formwork, this volume will prove invaluable to designers and constructors alike. With formwork representing anywhere from 35 to 60 percent of the cost of a concrete structure, formwork should be carefully considered when selecting building designs, layouts, structural member sizes and construction methods. Forming Economical Concrete Buildings will offer the reader substantial savings through the integration of the forming system into the total building process. Key subjects include: challenges in making concrete economical, effect of form tie selection on project cost; and quality management of accelerated construction.

Abstract:

Quality management is described as a system whereby technology is managed in such a manner as to result in concrete construction being accomplished within the minimum time. Quality is measurable and stands for conformance. Goodness does not relate. Only the contractor doing the work can manage the quality of the work. He cannot rely upon owner inspection. Quality management is performed by other than members of the operating construction team. The forces leading to current pressures for rapid construction are outlined. The sources of problems, their identification and correction procedures are traced. Findings of the National Conference on Quality Assurance in the Building Community are related to the subject. Technology of concrete is discussed and related to accelerated construction. Subjects include: contract documents, national standards, reinforcing steel, formwork, placement, compaction, testing and management techniques.

Abstract:

The new World Headquarters Building for Elf Aquitaine in Paris, France was designed by a Canadian architectural firm who won the commission in an invited design competition in 1979. Work on construction documents began in Paris in January 1981 and construction began early in 1982. Bouyges, the contractor for the reinforced concrete structure, undertook extensive studies to develop a special formwork system for the facade structure since there is little if any background of experience to draw on in France in the construction of high-rise buildings. At 48 stories this was a building of very significant height and would require a whole new approach. The result of these studies was a very ingenious system of facade forms, fabricated entirely in steel and consisting of column and beam forms, complete with integrated working platforms, access ladders, and 2 story high protective mesh screens. A system of alignment nibs insured faithful adherence to the allowable tolerances both vertically and horizontally. Although the research and capital costs were significant, substantial cost savings were nevertheless made in the erection of the structure both in time and labor thus confirming the validity of this formwork design.

Abstract:

The Westbury Condominium Project is a forty story reinforced concrete tower surrounded by a five-story garage. The horizontal dimensions of the tower are only 41 x 41 ft. The design and construction management team worked within rigid parking, set-back, and height restrictions to produce a marketable building design on a difficult site in a heavily developed area. The contractor used time-lapse film analysis, video observation and an ongoing work crew training and motivation program to achieve a sustained 1.25 working day per tower floor construction cycle.

Abstract:

Presents a basic analytical method for shoring and re-shoring loads of multistory buildings. Discusses the factors that must be considered, the assumptions for simplification of the analysis and shows the method for determining the estimated loads that will be transferred to the structure. Presents the procedure required to determine the ability of the structure to resist the estimated loads with an appropriate safety factor and the adjustments to the construction procedure that must be made in the event the applied loads are in excess of the capacity of the structure.
