Absolute Planker is an achievement that requires the player to upgrade their plank box to hold 100 of each plank. This requires a total of 500 contract credits earned while doing Construction Contracts. The plank box costs 50 contract credits, the first upgrade costs 150 contract credits and the second upgrade costs 300 contract credits. These can all be bought from the Estate Agents Shop.
Since the maximum amount of credits per contract is 5, the minimum number of contracts to finish the achievement is 100, which is the same amount needed for the last achievement in the chain: Construction Contracts V.
