A Review of Fire Retardants for Commercially Important Polyurethane Foams
Abstract: The review covers various additive and reactive fire retardants used to render flexible and rigid polyurethane foams fire retardant. Literature sources are mostly from technical publications, patents, books and handbooks since 1962. Various fire retardants such as phosphorus-containing compounds, halogen-containing compounds, nitrogen-containing additives, silicone-containing products and miscellaneous organic and inorganic additives have been used to render polyurethane foams fire retardant. Some heatresistant groups such as carbodiimide, isocyanurate and nitrogen-containing heterocycles …

An Empirical Study Summary on Integrated Building Commissioning for New US Federal Domestic Construction Projects
Abstract: Current management practices for federal domestic construction projects need to be modified to mitigate the negative effects newly constructed buildings have during the first few years of occupation. These negative effects include poor indoor air quality and poor performance of its tenants during the initial years of building occupancy. This empirical study focuses on the staff of the US Mission to the United Nations (USUN) as an off-site temporary facility …

Influence of Recycled Coarse Aggregate on Properties of Concrete
Abstract: This study focuses on the influence of recycled coarse aggregate (RCA) on properties of concrete. Five different mixtures of RCA replacement comprising 0, 25, 50, 75 and 100% RCA were used. It was found that workability, saturated bulk density, compressive strength and flexural strength decreases with increase in RCA content in concrete. 100% manually RCA concrete passed the 17 kN/m2 compressive strength limit generally acceptable for concrete work of non-high …

Re-engineering the Engineered Construction Organization
Abstract: The concept of organization as a basic information processing system to provide flexibility and adaptability in highly uncertain and turbulent construction environment was used to design a post-bureaucratic organizational structure particularly for construction industry. The different divisions/departments in the organization are developed as interacting information processing subunits generating and disseminating a continuous flow of data/information. In addition to proposing the efficient way of vertical communication for productivity improvement, the proposed …

Time Overrun Causes in Public Construction Projects in Saudi Arabia: Contractors’ View
Abstract: The time schedule in construction projects is one of the prime measures for project success. However, the construction industry worldwide is full of projects that were completed with significant time overrun. This problem is critical and has negative effects on construction parties in terms of growth in adversarial relationships, mistrust, litigation, arbitration and cash flow problems. This study aims at identifying the time overrun causes in public construction projects in …
