This project is the biggest in LDA's history and there are a number of firms involved who have been given the the task of purchasing the land from land owners and handing it over to LDA. LDA is not directly responsible for compensating the land owners. I read a news report on Dawn a few months back. The land owners on whose lands LDA City is going to be built were demanding compensation.
First of all the project is massive, I doubt LDA can pull it off, considering their last major project was the Johar Town fiasco. I don't expect this project to be completed in even 15 years. Corruption is going to be rife, it is a money minting scheme more than a public benefit project. I expect the prices of files to fluctuate wildly. Scandals are to be expected. If it was my money, I wouldn't put it in this cesspool.
