Buildings are enduring, and cities have even longer lives. Their impacts extend into the lives of several generations of our predecessors to the consequences of unspecified resources, environmental pollution, and decaying climate conditions. The identification of likely impacts of construction projects on the environment according to severity is a task that must be accomplished for minimizing those effects. This study identifies the most common environmental impacts of construction projects in the Pauh Putra Main Campus, Universiti Malaysia Perlis and proposes the measures for their mitigation. The methodology includes a review of pertinent literature, observations of the general environmental effects of on-site construction activities, focus groups, and a survey among university staff, students, and construction workers to determine their perception regarding the environmental impacts of construction activities. The collected data from 50 respondents was presented in tabular form and analyzed using the Statistical Package for Social Science software. The responses on the impacts of the ecosystem, natural resources, and public are linked to their relative importance index (RII). Most participant s were aware of environmental impacts caused by the construction project which prominently affected the ecosystem in terms of "noise pollution,""dust,"and "air pollution"(which are ranked first, second, and third with RII values of 0.57, 0.52, and 0.52, respectively). The majority of the participants ranked "use technological innovations materials and methods such as the industrialized building system"as the mitigation measure of controlling the adverse environmental impacts. The long-term asset value of a building depends on its capability to fulfil user needs, withstand changing environmental circumstances, and survive the progressing expectation of sustainability design quality.

Rebound hammer tests are generally preferred as a non-destructive testing method as compared to destructive testing methods such as compression tests. In this study, a general series of rebound hammer tests and destructive tests were carried on in a heavy concrete laboratory. A set of concrete cubes measuring 100 x 100 x 100 mm were cast and subjected to water curing for 7, 14 and 28 days to obtain the cube strength and rebound number. Three grades of concrete, namely M20, M25 and M30 were used in this experiment. At 28 days, the minimum target strength should be 30 MPa. The rebound hammer tests were conducted before the compression tests. The data obtained for each test was evaluated and tabulated in the findings of this study. It was found that the variation between predicted strength and experimental strength for the rebound hammer test was 0.18%. This indicates that the rebound hammer test is able to predict strength with acceptable accuracy.
