Besides guarantying smooth work progress, it affords project managers the chance to identify early warning signs for peremptory remedial actions to keep the project on schedule and to budget. However, pertinent barriers can suppress the realization of the benefits of an accurate assessment of construction progress. This study aims to identify, examine and prioritize the critical barriers militating against accurate project progress measurement in the Ghanaian construction industry. Sixteen barriers identified from the literature were administered in a questionnaire survey to professionals with tier one construction firms and consultants. Sixty experienced construction professionals practising with tier-one construction firms and consultancy services took part in the survey. The relative importance index technique was used to rank the factors and correlation in responses of the two parties tested by the Mann-Whitney <em>U</em> statistics. The most critical barriers perceived by the professionals were 1) Reliance on Supervisor’s Judgement, 2) Generic and Non-Systematic Approach, 3) Variable Quality of Data and 4) Intricate Measurement Reports. Other highly ranked barriers include 5) Lack of Timely Information, 6) Laborious Data Gathering and 7) Quality Integration Constraint. The findings underpin the need to minimize dependence on subjective opinions and mere experiences of supervisors for assessment of project progress in this age of information technology. Incorporation of a level of automation into traditional progress methods will not only reduce human errors introduced into manually collected data but facilitate visualization of progress reports. Contiguous to a clear specification of the method of progress measurement in the contract document, a system that conveniently integrates cost, time and scope of work into progress measurement must be pursued. Addressing these identified critical barriers will consolidate current construction progress management practices.展开更多

Progress management and construction quality management are very important contents of the smooth development of civil engineering projects. The above is the analysis of the construction progress management and construction quality management of civil engineering projects, hoping to further improve the management level of civil engineering projects, and accelerate the development pace of Chinas construction industry.展开更多

The former is to recognize the scientific findings and research results by which CAS scientists bring to light natural phenomena, laws and properties in their basic and applied basic research. The latter is to award major inventions or research results produced by CAS scientists that have contributed greatly to the promotion of S&T progress, and social and economic development. In 1997, 68 research projects won the CAS Awards for Natural Sciences, and 106 research works won CAS Awards for S&T Progress. The following are profiles of some of the prize-wining projects.展开更多
