Construction safety audit is a prescribed course of action for assessing accident prospective and safety performance in the prerequisite of new construction schemes, the development and rehabilitation of existing structures and in maintenance of building structures. The main objective of this study is the identification of accident prone areas on the project site from First Investigation Report (FIR), to study the effect on development of statistical connection between accident rates and various factors that causing accidents. The scope of the study is to reduce accidents on construction site and its surroundings, reducing severity of accidents so as the necessity for costly remedial work is reduced. The aspect of safety is taken on low priority basis throughout the execution of construction projects in India. The area selected for the study is Chennai, a metropolitan and capital of Tamil Nadu. Tamil Nadu lies in the southernmost part of the Indian Peninsula and one of the 28 states of India. The accident analysis is prepared from five years statistics. Various types of labours and staffs are interviewed accordingly in order to get the clear depiction of site accidents with the personal measure which is the ultimate goal of this research paper.

In the Lubumbashi plain, the dominant soils are acidic Ferralsol that contain small amount of available phosphorus and nitrogen. The organic matter content is also limited. This study evaluated the effect of Arbuscular mycorrhizal fungi (AMF) on root colonization in Phaseolus beans growth performance and yield. Three soils with a pH 5.8; 6.2 and 6.5 respectively were included. We also studied the effect of increasing doses of P2O5 in beans by providing 25kg of P2O5/ha, 50kg P2O5 ha-1 in combination with AMF inoculation. The results show a high frequency of colonization at a pH of 5.8 (69%); a plant height of 56 to 58 cm with 10 leaves and 6 pods per plant for a yield of 2095kg ha-1. However, above pH 6.2, root colonization is low (31 to 61%) and plant height ranges from 27 to 39 cm with 4 to 6 pods for a yield between 631 and 1479 kg ha-1. The effect on plant response of 25kg P2O5 ha-1 in combination with AMF inoculation was statistically significant for all measured parameters. Finally, this study compared the efficacy of inoculum produced on three different way on colonisation efficiency of beans. Inoculum produced by using Plantago lanceolata as host species contained more spores and resulted in better-colonized roots compared to inoculum coming from Sorghum vulgare or clay inoculum.
