Construction/Interior Site Schedule Example (incl. JSON Template)

Characteristics of the Construction and Interior Industry

Construction sites or commercial space interior works are industries that are highly sequential and bound by physical constraints. You cannot start the 2nd-floor floor construction without finishing the 1st-floor pillars, and you cannot lay the flooring if the ceiling paint hasn't dried. In other words, Finish-to-Start (FS) relationships, where the successor task can only proceed when the predecessor task is 100% complete, account for more than 90% of the entire project.

Also, since numerous field workers from various subcontractors (electrical, carpentry, painting, plumbing, etc.) are deployed in narrow spaces, if processes get tangled or workspaces overlap, fatal Idle Time occurs. This directly leads to an increase in field labor costs and becomes the biggest cause of eating into the project's profitability. Therefore, precise daily schedule management and shortening the construction period are evaluated as the core competencies of a site manager.

Features of Interior Construction WBS Structure

The WBS of a general commercial space (office/cafe) interior construction has the following flow:

• Demolition & Temporary Works: Tear down existing structures and remove waste. Since it generates a lot of noise, this schedule is often placed on weekends or at night.
• Plumbing & Electrical: Foundational work to relocate electrical wiring and water pipes that will be hidden inside the walls.
• Carpentry & Metal Works (Framing): Build partition walls (lightweight partitions) and do ceiling louver work to outline the space. If this process is delayed, it's a critical path that stops all subsequent finishing work.
• Painting & Finishing: Apply paint after putty work and do wallpapering. Since drying time is required, Lag time must be reflected in the WBS. Then flooring and lighting fixtures are set up.

Shortening Construction Period and Reducing Costs using Rudia Gantt

Rudia Online Gantt perfectly supports the 'Include Weekends' feature and the Specific Holiday Registration feature, accurately calculating the schedule of rush construction sites that run without days off.

By looking at the timeline of Rudia Gantt, the site manager can find tasks that do not overlap in pathways (e.g., bathroom tile work and main hall carpentry work) and place them in parallel, thereby drastically shortening the overall construction period. Also, by printing a neat PDF schedule generated by the Export feature and sticking it on the wall of the site container office, communication errors with foremen can be reduced to 0%.
