Before embarking on any project, rea list ic planning and, consequently,a control proced ure must be in place to enab le the parties to manage the pr oject with sufficientdegree of author ity and certainty.This paper addresses issues associated with the implementation of project plann ing and control,identificati on of impacts in the implementa tion of proj ect pla nn ing and the critical successfactors of project planning. A qu estionn aire survey was conducted on construction profession alsand contractors involved in the ru nning of cons truction projects. The survey results showed tha tcommon problems associated with the project plann ing and control are the lack of experiencedstaff and poor coordination by the contractor.During site ope ra tion, a delay in de cision making aggravates the effect of po or planning andcont rol and mu ch of the effect of pro ject planning rests on the pro-activeness of expe riencedsta ff. The posit ive impact associated with proper planning and contro l is the high probabil ity offinish ing the project on time whil e the negative impac t is that it is a time-co nsuming and cos tlyprocess. The critica l success factors identified from the survey are Excellen t Teamwor k andExperienced Team.
