Most important ability required for Project Management is to plan the whole construction project = ability for work preparation.
It is to plan the project without any type of waste (time, money, resources, etc.) and troubles.
A project manager needs to understand needs and wants of all relevant parties including clients, the head contractor, SUBs, Neighbors, property Buyers.
After all, if some part of the project is planned unreasonably the project will be eventually delayed or get stack.
Also it is important to understand the whole picture of supply chains.
Major important works needs to be done by a Project Manager
Develop a detailed project plan with some schedule allowance
Assign a right job to a right person
Prepare a backup plan
Manage project budget
Manage project schedule
Communicate relevant parties effectively
Overall, a good Project Manager is capable to do:
Understand the whole picture of a construction project
Act systematically based on an effective strategy
Make things happen
