Residential Building Projects
We analyze drawings, bill of volumes etc. of 25 concrete buildings in Istanbul.•
Ratio of security expense towards total building expense is 1.9per cent based on 2013 rates.•
Protection expense per man-hour is 0.85 USD and security cost per device location is 5.68 USD.•
We compare our outcomes with an investigation that centered on 30 jobs in Istanbul.•
Due to the fact building location increases, the share of protection expense decreases.
Fatal construction accidents tend to be significant problem in Turkish building industry. Although brand new extensive legislation happens to be inured recently; standard of consciousness on the market is unsatisfactory and protection is regarded as an extra expense. Small or middle scaled residential projects have a big share in the industry and most of the fatal accidents often take place on such work sites. Focus for this research is small and middle-scaled domestic construction web sites. Drawings, technical requirements, costs of levels of 25 concrete domestic structures with total areas that differ between 230 and 118, 200 m2 in Istanbul had been examined. Website visits and information gathering had been done from website engineers. This study aims to offer a method for security cost estimation for initial phases of construction bidding stage using threat evaluation activities and building task scheduling by focusing on building tasks. Also, a price evaluation was carried out in addition to results had been compared and reviewed with a former task that focused on 30 concrete domestic tasks in Istanbul. Primavera P6 was utilized for scheduling, and risk assessment was performed with the techniques applicable for building tasks (in other words., L matrix and Fine-Kinney). Eventually, activity-based strategies were used for expense estimation. The outcomes of this research expose the percentage of protection expense on total building cost is 1.92percent. In addition, to comply with the existing legislation and minimize dangers; 0.85 USD per man-hour must certanly be spent relating to 2013 rates and security expense per device location had been found as about 5.68 USD.
