Construction projects often require the integration of engineering disciplines (civil, structural, electrical, mechanical, geotechnical, etc.) as well as interaction with technology and sophisticated equipment that demand unique construction techniques and methods. This can contribute to unique subcontracting arrangements, special financing, risk insurance, compressed schedule timelines, sustainable infrastructure, complex logistics, adaptation to changing governmental regulations, and internal/external constraints, all of which have the potential for significant increases to project and capital costs. The construction industry is almost entirely based on a competitive market environment for project cost, schedule, and performance delivery. Construction projects are becoming increasingly larger, more complex, and more globally competitive, each bearing the potential for an adversarial relationship between the buyers and sellers. Construction managers and project managers; • Contractors; • Subcontractors; • Construction specialists, such as estimators, schedulers, cost engineers, project control analysts, and quantity surveyors; • Architects, designers, and engineers; • Regulatory agencies and governments; • Nongovernment organizations (NGO) and private enterprises; • Environmental groups; • Community groups; • Prospective homeowners; • Risk management specialists; • Geotechnical and hazardous material experts; • Real estate developers; • Construction material and equipment vendors and suppliers, and logistics and transportation specialists; • Construction consultants and attorneys; • Insurance, banking, and financial institutions; • Construction industry trades and professionals; and • Other stakeholders in the construction process, from land acquisition through design, construction, and occupancy. Lack of planning, poor preconstruction preparation, poor communication and teamwork skills, and weak contract administration are leading causes of problems on a construction project.
