Construction Scheduling Software

free construction scheduling | PriMus KRONO | ACCA software

The Construction scheduling software that helps you improve project efficiency and optimize work execution costs.


Try the software together with free technical support for a month, then choose the subscription plan that suits you best.

With PriMus KRONO you have all the tools for Project Time (Gantt), Economic and Financial planning.

Automatically produce Project Time Schedules directly from the project's cost estimate document prepared with PriMus, compare the estimate against works execution activities, monitor tasks, costs, timing and resources, get summary reports and diagrams and export them to Word® and Excel®.

Time-Schedule preparation | PriMus KRONO | ACCA software

Time-Schedule preparation

PriMus KRONO is the software for creating a works time schedule including the analysis of timing, costs and resource requirements.

The software allows you to manage:

  • the design stage with GANTT charts, financial diagrams and resource reports;
  • the build stage with the execution GANTT chart, reports together with cost and timing variation diagrams.

A specific step by step procedure guides the user in defining the Time Schedule Plan, from creating the work item to defining quantities in the GANTT report.

Activities and Work Sections (Folders) allow the user to sub-divide time schedules into multiple levels and according to the most appropriate structure.

Activity data can be inserted either using analytic data entry dialogs or even graphically with features that allow the user to:

  • shift activities along the timeline;
  • define activity duration;
  • sub-divide them into multiple periods;
  • manage connections with critical paths.
Time Schedules from a DCF file | PriMus KRONO | ACCA software

Produce Time Schedules from a .DCF file. and activity Drag and Drop

The Time Schedule can be generated by importing “.DCF” file produced with PriMus.

When importing a “.DCF” file (price list, BoQ or construction cost management documents) the generated time schedule document automatically acquires the necessary data, (general data, activities and unit rates, quantities and amounts and work sections).

You can import activities from other PriMus KRONO time schedules or from PriMus construction estimating with simple drag and drop actions.

Time schedule and financial plan management | PriMus KRONO | ACCA software

Time schedule and financial plan management

PriMus KRONO allows you to:

  • manage and customize climate conditions;
  • configure the calendar setting up work days and bank holidays;
  • choose the time scale;
  • define the schedule layout;
  • define a new commencement date for activities, periods or for the whole time schedule;
  • graphically represent work suspensions;
  • customize the graphical styles for each task bar.

By means of the financial definition of the project, PriMus KRONO allows the operator to control lead times, advances in work, guarantees, payments, etc.

With the economic and financial diagrams, daily productivity based data can be viewed filtered down to a given date, both during the planning and the works execution phases (work in progress).

Planned and Works Execution time-scheduling | PriMus KRONO | ACCA software

Planned and Works Execution time-scheduling

PriMus KRONO handles both the Planned and Works execution time-schedule in the same document: simply indicate the real works start date to get the works execution time schedule.

The execution time schedule is generated automatically from the project. It can be easily adjusted by shifting tasks or changing their duration. The works execution time-schedule indicates the amounts of work actually completed.

The completed work amounts can be displayed graphically or analytically by entering for each Activity or Period, the completed Quantities.

Printing Time-schedules and Reports | PriMus KRONO | ACCA software

Printing Time-schedules and Reports

PriMus KRONO allows you to print the planned or works execution time schedule with the Table of Activities and Table of Dates and Amounts.

These documents can be printed or exported to Word, HTML or PDF file formats.
An internal word processor lets you create and manage your Time-schedule Report and the Works execution Report.

Reports can be printed on normal paper or exported in RTF format.

Rate Analysis work sections | PriMus KRONO | ACCA software

Rate Analysis of work sections

PriMus KRONO also integrates with the PriMus software taking full advantage of the Price List Management features: a list of time schedule activities can be opened as a normal PriMus Price List document and modified in its dedicated internal editor.

Any changes (for example rate percentage updates) are then re-aligned with the PriMus KRONO document.

The PriMus KRONO integration process with PriMus, makes it possible to edit work items and activity analysis (resources, quantities, costs…) or create new ones which will be automatically updated in the time-schedule.

Control of lead times and advances in work | PriMus KRONO | ACCA software

Control of lead times and advances in work

By means of the financial definition of the project, PriMus KRONO allows the operator to control lead times, advances in work, guarantees, payments, etc.

With the economic and financial diagrams, daily productivity based data can be viewed filtered down to a given date, both during the planning and the works execution phases (work in progress).

Printing Reports and management | PriMus KRONO | ACCA software

Printing Reports and their management

PriMus KRONO allows you to monitor the Project and Works Execution Time schedules at any moment, providing all the necessary data to assess effective resource availability to carry out the planned works on schedule.

In particular, specific Reports allow:

  • to view specific activity requirements even for user-defined intervals of time;
  • to evaluate material requirements deriving from work activity analysis (materials, labour, freight, etc.) and for certain date ranges;
  • to compare the Works execution time schedule with the Project time schedule to detect and underline changes (duration, Start and End dates);
  • to query Works Execution time schedule to highlight executed work amounts at a certain date, deviations from planned amounts specified on a given date or the programmed termination of the works date (i.e.: amounts still necessary for completion of works).

PriMus offers you a free conversion service for price books and price lists.

If your database is in the Excel format, you can import it directly into PriMus. Alternatively, the conversion tool, PW-CONV, already provides you with various procedures for converting price list or price book databases (for which you must detain the license for use) into a format which is compatible with PriMus.

If the conversion procedure isn't available yet, you can always request a conversion using our dedicated service available in the program's Home section. Our team will then evaluate the feasibility of the conversion process.

The PriMus suite is composed of single stand-alone software solutions designed to meet every kind of specific need:

  • PriMus, for construction cost estimates, bills of quantities and works estimates;
  • PriMus KRONO, for construction project management, time scheduling and planning;
  • PriMus TAKEOFF, for preparing Cost Estimates and Bill of Quantities from CAD and PDF files;
  • PriMus IFC, for construction cost estimates from BIM Models.
