10 Steps for Construction Scheduling

How to Start Your Construction Project with Merlin Project

Construction Scheduling

Scheduling and monitoring of dates of construction sequences is done in so-called construction schedules. They serve to coordinate and control all crafts of building projects. Read on to learn how to develop a construction schedule in 10 easy steps. Launch Merlin Project and open a new blank document.

1. Entering the start date of the project

Click on »New Project« to replace this default title with one appropriate for your construction project.

Enter project title

Two columns over enter the expected start date of the construction into the field »Given Earliest Start«. You will need to scroll sideways to get there.

Enter expected start date

2. Transferring positions from the service specifications to individual project activities.

Add new activities by pressing »cmd + N«, via the menu item »Insert > Activity« or by clicking on the plus symbol in the upper left corner of the window.

Insert activity

Enter the positions from the service specifications, by craft or stage of construction, as the respective titles of the new activities.

Enter title for the activity

3. Enter into Merlin Project the work days for the individual activities of the construction schedule by adopting them from the quotation costing (targeted hours). I.e. earthwork: 96 hours

For the activity »earthwork« type into Merlin Project's column »Given Work« 96 hours, respectively 12 days (96 hours : 8 hours/day). Proceed in this fashion with any further activities.

Enter work days for the activities

4. Determining crew size, i.e. earthwork:

Supposing you had three workers (resources) and were to assign »worker 1«, »worker 2« and »worker 3« to the activities.

Add the required resources by clicking the plus symbol in resource view. Name the resources meaningfully. I.e. »worker 1« etc.

Enter resources

5. In Merlin Project 5 resources can be assigned to an activity. They are planned to do the work of said activity.

Drag and drop the resource to the appropriate activity or check the respective »Assign« check boxes in the resource dialog.

Assign resources

6. Merlin Project determines the durations (man days) of activities. I.e. 8 hour work days for earthwork:

96 hours : 8 hours/day = 12 days : 3 workers (resources) = 4 days duration.

When assigning multiple resources to one activity, by default they share work proportionately.

Resources share the work of an activity

7. Labor cost is automatically calculated according to resource specifications in Merlin Project.

In the »Resources« view, give as »Standard Rate« the labor cost for a resource. I.e. 70 €/hour.

Enter labor costs

8. Checking stipulated costs. I.e. for earthwork:

Summed net services 6720 € : 96 targeted hours = 70,00 €/hours

Merlin Project computes the total from the given standard rate of the assigned resource and displays it in the column »Planned Costs« of i.e. the view »Plan/Actual Comparison (Cost)«.

check stipulated costs

9. Optimizing time intervals between activities and checking for parallel tasks

You may link activities and groups logically in order to visualize dependencies of the progressing construction project. Most common is the »End to Start« linkage representing linearity.

link activities

10. Grouping multiple thematically related activities. I.e. crafts and their respective positions.

»View Options« offer a check box called »Group Boundaries« for this purpose.

Group Boundaries

A concluding tip: You can even follow these steps with the free demo version. And if you don't have any time, just download the example project.
