Sample project
Erection Plan
Play the schedule to see steel deliveries build a buffer before erection starts.
Explore a simple eight-deck building in 3D, plan, and elevation. Play or scrub through the schedule to see setup-week deliveries build a steel buffer, then follow the raising gang and planned man-hours, tons, and picks. Select a sequence to jump to its midpoint. Earlier decks are shown as erected; later decks remain transparent.

Raising gang schedule
One setup week, then one gang working five 10-hour days per week.
Live sequence breakdown
Production through the schedule
Cumulative planned quantities at the selected time. Man-hours cover the six-person raising gang working 10-hour days. Tons and picks are spread evenly within each sequence; displayed values are rounded to whole numbers; calculations retain full precision. Setup and follow-up crew hours are excluded.
Weekly production
Tons, pieces and picks by workweek; raising gang hours trace the available crew time.
Work mix and labor
Ratios by sequence, indexed to S1 = 100 so their changes can share a time axis. Exact values appear for the active sequence.
Assumed loaded labor rate: $120/MH, blended for the five-tens schedule. Planned erection man-hours × $120; no additional overtime multiplier. Illustrative labor only, excluding cranes, materials, setup, follow-up crews and other project costs. This is not actual spending.
Erection logistics plan
Building grid, crane operating area, temporary access, laydown, trailers, parking and hoist access.
Site elevation and access
Tower crane, buck hoist, deck elevations and the active erection sequence.
Sequence data
Select a row to show that sequence in the model. W = workweek; D = workday. Week 1 is setup. Date ranges show the workdays touched by each sequence.
| Sequence | Schedule | Tons | Pieces | Picks | Picks/ton | Crew-days | Erection MH |

Take the plan with you
Create a three-page PDF for the selected workday. It includes the 3D model and schedule, production charts with the selected sequence's work class breakdown, plan and elevation views, and the planning basis.
Connect the work to the schedule
Each deck represents a sample work package. The schedule links those packages to planned time, giving a simple 4D view of the work. The timeline connects that view to planned man-hours, tons, and picks.
This view uses the workbook baseline.
About this example: This is a simplified planning illustration, not a structural design or erection instruction. The blocks show sequence locations; the workbook quantities are illustrative and are not a takeoff of this building. Access and shakeout locations are schematic; truck turning space and deck storage capacity are not checked. Details needed for a real project have intentionally been left out.
