The need to predetermine the capacity of a contractor to deliver a project prior to the contract award/commencement of such a project getting more evident in Nigeria based on the rate of failure of contractors to deliver. This, therefore, calls for analytical form of evaluation to pre-determine the capability of a contractor before award of contract is made. This work applied the Mankilik’s modified C-rating technique originally developed for determining the readiness level (for combats or routine operation) of the military via sub-resources, to a civilian environment. The modified C-rating technique is termed “λ-Method”. Four (4) levels of readiness exist namely, C-1 for fully ready, C-2 for substantially ready, C-3 for marginally ready, and C-4 for not ready.

In particular the technique was used to determine the levels of readiness of three (3) contractors (1.2. and 3) that bade, each for three (3) jobs, namely a drilling, a pipeline construction and supply projects. It was found that for the drilling project, Contractor 2 was not ready while contractors 1 and 3 were above substantially ready and almost substantially ready, respectively. For the pipeline construction project it was found that contractor 1 is almost fully ready, contractor 2 almost substantially ready and contractor 3 above substantially ready. For the supplies project, all the contractors were fully ready as they all possessed the requisite sub-resources to deliver the services required.
