The application of the "line of balance" technique to the construction industry

Abstract: BECAUSE OF THE INCREASING COMPLEXITY OF CONSTRUCTION PLANNING, SCHEDULING, PROGRAMMING AND CONTROL, A NUMBER OF PLANNING AND CONTROL METHODS HAVE BEEN INTRODUCED RECENTLY. A SIMPLE, AND EFFECTIVE MEANS OF CONTROL IS THE "LINE OF BALANCE" TECHNIQUE, WHICH CAN BE APPLIED TO A WIDE VARIETY OF CONSTRUCTION PROGRAMS. THE LOB TECHNIQUE IS DESCRIBED BRIEFLY WITH SPECIAL REFERENCE TO THE CONSTRUCTION INDUSTRY, AND IS ILLUSTRATED WITH PRACTICAL EXAMPLES DRAWN FROM THE FIELD. /RRL/

Labour-intensive methods in low-cost road construction: a case study

Abstract: In most developing countries capital is so short and unskilled labour so abundant that it seems only common sense to use such labour to the extent feasible in capital construction projects. As part of the world employment programme the ilo is therefore making a major effort to develop efficient labour-intensive techniques in public works and construction, having especially in mind those countries with vast programmes of infrastructure development. This article is a modest contribution to that effort. It is the record of an initially highly mechanised road construction project that ran into almost every conceivable difficulty and had to resort to more and more labour-intensive methods.(a) /TRRL/

Statistical Quality Control of Highway Construction and Materials

Abstract: The objective of this report is to review existing local practices used in establishing and enforcing highway specifications and construction processes and to compare these practices With p~ocedures based on statistical quality control concepts. In order that statistical quality control concepts may b.e prOperly used where applicable, the first part of this report considers the general theory underlying the use of statistical control methods and the development of different types Of acceptance plans which may be used in the highway construction industry. The second portion of the report is concerned with analyzing and comparing Kentucky's current specification requirements with typical quality control requirements established using basic statistical theory. Specifications used by some other agencies which are based on statistical principles are presented to illustrate the use being made of this type of acceptance plan. Historical data compiled for various contract items used in highway construction in Kentucky are also presented as background information useful for establishing statistically derived specifications in the future.

Owner’s Return from CPM—Fact or Fiction

Abstract: In addition to its use for construction scheduling, Critical Path Method (CPM) benefits the owner in all aspects of project development, providing a plan for earliest possible completion at minimum cost, with better financial management and fewer delays.

Analisis rework pada proyek konstruksi gedung di kabupaten badung

Abstract: Rework is unavoidable from the world of construction, Rework can be a devastating effect on the performance and productivity of both the consultant and the contractor. This study aims to determine the main factors causing rework, efforts to reduce rework. The analysis used the analysis Multivariant factor analysis with the help of Statistical Package for Social Science (SPSS) for Windows version 17.0. From the results obtained by factor analysis the main factors causing the occurrence of rework are: aspects of the owner (poor communication, poor coordination, poor information flow), aspects of planning consultants (lack of information in the field, lack of communication, the situation in the picture on the ground is not suitable). aspects of construction management consultants (lack of information in the field, lack of communication, lack of control), aspects of mechanical electrical plumbing contractors (Materials misdirected, MEP staff inexperience, lack of knowledge about the character of the material, the amount of overtime), aspects of the contractor (lack of competence foreman, foreman lack of experience, lack of experience, the quality of labor is bad, the error in interpreting the specification), aspects of operator (poor flow of information, lack of communication, lack of coordination, lack of operator experience). Efforts to systematically reduce rework most effective according to the respondent's answer is: Systematic planning, detailing and describing the project at every stage of the steps to be taken to achieve quality objectives, set standards of communication, coordination and construction project sinkronasi work with all parties involved in the implementation of the project, Constructing specification limits and criteria and quality standards to be used in engineering design, procurement and construction materials.

Cross-Country Pipeline Construction

Abstract: The construction of large diameter cross-country pipelines involves a repetitive sequence of operations, each of which must be carefully planned and scheduled to attain a high rate of production. These operations can be identified as right-of-way clearing, ditching, stringing, bending, lining-up, welding, coating and wrapping, lowering, backfilling and cleanup, and testing. Each of these operations is briefly described with an emphasis on newly introduced methods and equipment. Construction management is of crucial importance to a successful pipeline project. Various skills must be assembled, the several operations must be integrated, and the construction project must function as a continuous production line. Each project becomes a cost center, and explicit records of cost and performance should be maintained. There remains a basic need for further research, and for its application and acceptance by owners, contractors, and labor personnel, if the pipeline construction industry is to realize its full potential.

Design construction, and initial evaluation of experimental test sections of asphalt containing synthetic rubber

Abstract: THE 16 TEST SECTIONS OF ASPHALT CONTAINING RUBBER WERE CONSTRUCTED AS PART OF A PRIMARY HIGHWAY PROJECT IN SOUTHEASTERN UTAH. THE EXPERIMENT CONSISTS OF 5 FACTORS AT 2 LEVELS, EACH INCORPORATED IN A ONE-HALF REPLICATE OF A 2 TO THE FIFTH POWER FRACTIONAL FACTORIAL EXPERIMENT. THE DESIGN PROVIDES THE BASIS FOR DETERMINING THE EFFECT OF EACH OF 5 FACTORS AND EACH OF 10 TWO-WAY INTERACTIONS ON PAVEMENT CONSTRUCTION, PERFORMANCE, AND DESIGN. THE EFFECT OF EACH VARIABLE WAS DETERMINED FOR THE CONSTRUCTION PROCESS, AND AN INITIAL EVALUATION WAS MADE. A DESCRIPTION OF THE CONSTRUCTION PROCESS, INCLUDING THE RUBBERIZING PROCESS, IS GIVEN. EVALUATION IS CONTINUING THROUGH MANY OBSERVATIONS AND PHYSICAL TESTS ON THE PAVEMENTS AND PAVING MATERIALS. FAILURE RATE OF PAVEMENTS WILL BE ACCELERATED BY THE REDUCTION OF HALF THE DESIGN THICKNESS. THE DESIGN PROVIDES A SOUND METHOD OF ANALYSIS AND OFFERS A DEFINITE BASIS TO DETERMINE WHICH FACTORS AND INTERACTIONS ARE SIGNIFICANTLY AFFECTING PAVEMENT PERFORMANCE AND DESIGN. /AUTHOR/

Transportation in Regional Plan for 1970s

Abstract: Regional transportation planning needs will increase in the `70s, but plan implementation will be more difficult Planners must recognize changing moods and forces affecting society Regional transportation planning should take new directions or place different emphasis on various aspects of planning The nature of this change relates to planning methodology and principles Methodology improvements should include better use of system logic, reallocation of planning funds, increased use of the multidisciplinary approach, and greater used of a goals-objectives planning framework Improved principles concern planning for integrated transportation systems rather than single mode facilities, positive use of land-use shaping influences of transportation, use of coordinated systems rather than single modal approach to financing and construction of improvements, and applying new transportation hardware or technology
