A multi-purpose EMMA should have been utilized for vast majority of work that is associated with a physically quantifiable unit of construction work scope to be measured in tens, hundreds or thousands. As for instance, large earthmoving or excavation works; the set up of underground piping systems (eg drainage or water reticulation); a network of roads & paving; concrete foundations & structures; buildings & finishes; or boundary security fencing, etc.

The EMMA consists of 3 'pages', such as 'INPUT' (Basic data that should be inputted to make EMMA operative), 'TABLES' (Spreadsheets for inputting target & actual progress percentages, man hours etc), and 'CHARTS' (Where inputted spead sheets are demonstrated similar to S-curves & histograms). The EMMA is utilized for the following purposes :-

• To arrange a target rate of progress (S-curve);
• To arrange an estimation of man-hours that will be transformed to manpower requirements (histogram);

• To record units estimated as complete each month;
• To record man-hours spent every month, in this manner automatically comparing the genuine rate of advancement and real utilization of manpower, with planned rates.
• Besides, unacceptable trends can thus be recognized and work re-scheduled, together with automatic amendments to manpower requirements that will result in achieving of target completion.

Preliminary needs for inputting are given below:-

• The projected total quantity;
• Interpretation of the unit (eg m3);
• A calculation of man-hours necessary per unit;

• The average number of hours executable each day;
• The average number of days executable each week.

Subsequently, inputting should be compliant with notes submitted. NOTE: For the EMMA to work, values should have been inputted to all lines in Sheet 2 TABLES, from Month 1.

The application of an EMMA will be useful for anyone who takes the liability to finish a work scope package on or ahead of schedule.
