Based on a benchmarking approach, this research quantifies the material wastage and its causes in different types of building projects. In a waste diagnostic survey, 38 project sites were surveyed. Results revealed that bricks, tiles, and plaster from mortar are the most wasteful materials, and improper worker's skills, poor supervision, and ...

for the precise categorization of this type of material shall be performed by experienced, technically competent persons. Maximum Allowable Quantity (MAQ): An MAQ is the maximum amount of hazardous materials allowed to be stored or used within a control area in a building. These limits are established by the CFC and are broken down by hazard …

The study investigates the level of construction material waste generated on building sites in South-South, Nigeria. The objective is to empirically establish the level of waste generated on building sites and compare such with the allowable value in estimates. Data were collected from 30 on-going public building projects for six months. …

Fire Code Maximum Allowable Quantities (MAQs) are limits on types and quantities of hazardous materials (chemicals) that can safely be stored and used in buildings. These limits apply to all buildings on UC property. MAQ limits are dependent on how the building was constructed, whether it has full automatic fire sprinkler coverage, and other ...
