    The quality of the drawings were quite poor and appeared to have been done in a rush with very little care taken. I got the impression he just wanted to grab a quick dollar and was happy to submit CAD drawings where the lines didn't even meet , so it was totally useless. After receiving his first submission from saranga86 I decided to give the job to a second freelancer ( ranjan82)who did a great job .

    Project Description:I require 5 simple 2D CAD drawings created from 5 sketches of abstract people figures / sketches. I would like this project completed within 2 days . The freelancer will require some art/sketching skills to fine tune the sketches , and then trace them into 5 separate CAD drawings ...

    Contractor claimed that his computer is not working and that he will deliver the project within 24 hours several times. The original bid is 2 days but the project has been delayed more than one month. In his last message he claimed that he will deliver within 24 hours, I waited for 7 days and again there were no results. I give him several chances on his 24-hour promises and now decided to cancel the project all together due to lack of communication and failure to deliver. I have given him many chances and it is now time to move on.

A Study on Soil-Steel Bridge Structures (Long Span) in Southern Highway in Sri Lanka for the Effects of Using Relieving Slab as a Structural Improvement

W.A.S. Gunathilaka

The Soil-Steel Bridges have been used as the underpasses and drainage structures in the Southern Highway Development Project for the first time in Sri Lanka. The Ring Compression method, which is based on two dimensional plain-strain idealizations, was used as the structural design philosophy to analyse the structure. The collapsing of a bridge led to controversy about the structural stability and the suitability of the structures to Sri Lankan climatic conditions. Meanwhile the structural improvements were
