What is the Construction Management

* In making a building green, apart from reducing the energy requirements, its positive impact on

economy and productivity also should be considered.

Construction Management

* Successful execution of a project depends upon—management, money, manpower, machinery and

material.

* Average of cost of civil works for a building at various levels are foundation: 10–15%, walls,

stairs and roofs: 30–40%, doors and windows: 12 to 18%, flooring 10–20%, Finishing 8–20%,

water proofing 8–12%. A provision of about 30% of civil works is required for water supply and

sanitation (12.5 %), electrification (12.5 %) and external work (5%).

* Commonly employed methods of planning in construction are bar charts and network method. In

network method one can adopt Program Evaluation and Review Technique (PERT) or Critical

Path Method (CPM). PERT is suitable in the management of works where previous data and

experience are not available. For building construction CPM is the best method.

* Elements of a network: Activity is defined as number of small jobs to be performed in a sequence

to complete a job. Event is an activity that takes place at a particular time. A dummy activity

neither requires any time nor any resource. It is used only to identify a dependency between

various events.

* Development of a network involves identifying various activities, finding out proceeding and

succeeding activity about each activity and drawing network. For each activity duration required

in terms of days or weeks is then worked by consultation with junior and senior engineers and

contractors. Then the following details are
