Due to the highly competitive commercial environment in the market in Yemen at present, the construction industry in Yemen, like other industries, is under pressure to reduce product development time and overall project costs, improve product quality, and satisfy customers. To keep pace with the competitive environment of the market in Yemen, most enterprises tend to adopt the best and new technologies, new management concepts and philosophies such as Total Quality Management (TQM) and concurrent engineering (CE) to achieve improvements in the process of product development. In this paper, the problem of fragmentation brought by the serial engineering in construction in Yemen is discussed firstly. Then, the integration process and CE adoption by the construction industry in Yemen are explained for enabling construction agencies in Yemen to improve the development process of their projects and to solve the current fragmentation problems such as the lack of communication, adversarial culture and the lack of customer focus, which allows the construction process to improve and become more effective and efficient.Sustainability 2019, 11, 3146 2 of 11 Current Issues in the Construction Industry in YemenYemen is a developing country, where problems in construction projects often lead to extra costs and delays. Studies show that in some developing countries, the actual cost of construction projects exceeds the original contract price by 30% when the project is completed [5,6]. The successful execution of construction projects, keeping them within the estimated cost and the prescribed schedules, primarily depends on the existence of an efficient construction industry which is capable of sustained growth and development to cope with the requirements of social and economic development and to utilize the latest technology in planning and execution [7][8][9].According to a report by the Yemeni Ministry of Public Works and Road, in the first seven months of the civil war in Yemen, the estimated cost of damage to infrastructure was more than $14 billion [10]. A survey by the Yemeni Ministry of Education also indicated that 1671 schools suffered damage, 387 needed major reconstruction, and 250 were destroyed in the civil war. The estimated cost of the damage was more than $300 million [9]. Due to the intensity of the civil war, reports can only assess the damages in the cities of Sana'a, Aden, Taiz, and Zanzibar, and data collection was stopped in October 2015. These data found an estimated $3.6 billion in damages to private homes. The total cost of rebuilding the damaged power facilities in the four cities is estimated at $335 million, most of which goes to repairing damaged power plants [9].Yemen is a developing country where project management often relies on traditional methods in most industrial sectors, including the construction industry. The construction industry in Yemen is an essential sector in the national economy of the country [11][12][13]. The majority of the construction projects in Yemen has been carried out in ...
After decades of civil war, Yemen is in a desperate situation, and the construction industry has been suffering from low productivity and poor performance. In order to improve the productivity for the Yemeni construction industry, Construction enterprises must adopt the best and new technologies, new management concepts and philosophies such as Total Quality Management (TQM) and concurrent engineering (CE) owing to achieve improvements in the process of product development. To ensure the successful implementation of CE in the Yemeni construction industry, it is necessary to assess the readiness of those companies to implement CE. In this paper, the BEACON model is used to assess the readiness of the Yemeni companies to implement the concept of CE, that assist in overcoming the construction industry's poor productivity and performance. A study assessing CE implementation readiness will help to promote successful CE implementation in the construction industry and enhance the efficiency of construction companies. The results show that most of the construction companies in the Yemen are not ready to implement CE. The main reason is that the enterprises rely heavily on traditional management methods, and need to improve the organization and management technology. The research results can provide theoretical support for construction companies, especially Yemen companies, to establish basis in implementing an appropriate CE approach for improving performance, and also help international construction companies entering the Yemen construction market to cooperate and implement CE.
