      Advancements in the control of construction equipment can have significant benefits in the industry. Better control can lead to improvements in safety, cost, labor turnover, and productivity. It is helpful to characterize ...
    • Pull-Driven Scheduling for Pipe-Spool Installation: Simulation of Lean Construction Technique 

      Iris D. Tommelein (American Society of Civil Engineers, 1998)
      Many construction processes include installation of unique materials in specific locations in the facility being built; materials and locations must match before installation can take place. Mismatches due to delay and ...
    • Linear Scheduling Model: Development of Controlling Activity Path 

      David J. Harmelink; James E. Rowings (American Society of Civil Engineers, 1998)
      There are several reasons why linear scheduling techniques have not been applied widely to construction projects even though they have been identified as very useful. If we consider the capabilities and the widespread use ...
    • Scheduling Projects with Repeating Activities 

      Robert B. Harris; Photios G. Ioannou (American Society of Civil Engineers, 1998)
      Construction contractors are often faced with projects containing multiple units wherein activities repeat from unit to unit. These projects require schedules that ensure the uninterrupted usage of resources from an activity ...
    • Integrated CAD/KBS Approach for Automating Preconstruction Activities 

      Mousa Tabatabai-Gargari; Hazem M. Elzarka (American Society of Civil Engineers, 1998)
      Preconstruction activities include design analysis, cost estimating, and value engineering. They are performed to provide clients with the data to make intelligent and informed decisions about constructing their facilities. ...
    • Interactions between Construction Planning and Influence Factors 

      Olusegun O. Faniran; Jacob O. Oluwoye; Dennis J. Lenard (American Society of Civil Engineers, 1998)
      This paper provides a framework for the development of strategies for improving construction planning practices. Interrelationships between construction planning and situational factors in the environments within which ...
    • Resource Leveling of Linear Schedules Using Integer Linear Programming 

      Kris G. Mattila; Dulcy M. Abraham (American Society of Civil Engineers, 1998)
      Since the early 1960s many techniques have been developed to plan and schedule linear construction projects. However, one, the critical path method (CPM), overshadowed the others. As a result, CPM developed into the powerful ...
    • Development of Computerized Specifications 

      Bayard E. Bosserman; Maurice E. Ford (American Society of Civil Engineers, 1984)
      This paper describes the history, development, implementation, and benefits of a computerized master specification system established in a consulting engineering/architecture company. Besides reviewing the problems encountered ...
    • Models of Construction Innovation 

      E. Sarah Slaughter (American Society of Civil Engineers, 1998)
      Construction innovation offers the potential for significant company, industry, and societal benefits. The objective of this paper is to present five models of construction innovation, which can provide a basis upon which ...
    • Bidding Practices of Subcontractors in Colorado 

      Ali A. Shash (American Society of Civil Engineers, 1998)
      Despite their significant role in construction projects, subcontractors have not been given fair attention by industry researchers. The literature contains very few studies focusing on subcontractors' bidding practices. ...
    • Neural Network Model for Parametric Cost Estimation of Highway Projects 

      Tarek Hegazy; Amr Ayed (American Society of Civil Engineers, 1998)
      This paper uses a neural network (NN) approach to effectively manage construction cost data and develop a parametric cost-estimating model for highway projects. Eighteen actual cases of highway projects constructed in ...
    • Time-Lapse Video Applications for Construction Project Management 

      John G. Everett; Hasan Halkali; Thomas G. Schlaff (American Society of Civil Engineers, 1998)
      Time-lapse recording allows lengthy construction processes to be recorded and played back in a much shorter time for subsequent analysis. Over the past decade, time-lapse video cassette recorders (TL VCRs) have replaced ...
    • Factors That Affect Process Quality in the Life Cycle of Building Projects 

      David Arditi; H. Murat Gunaydin (American Society of Civil Engineers, 1998)
      The factors that affect process quality in the three phases (design, construction, and operation) of the life cycle of a building project are identified and ranked by degree of importance. The perceptions of long-time ...
    • Bidding Considerations in Developing Countries 

      Edward J. Jaselskis; Alfred Talukhaba (American Society of Civil Engineers, 1998)
