▲ = pick over 85% of interpolated chart capacity. Teaching values only, not for lift planning. Crane chart: Liebherr LR 1300 SX product guide (Maxim Crane) , luffing jib lift charts No. 2316, 273,400 lb counterweight + 125,700 lb carbody counterweight. Sections are typical callouts from the framing plans by member type and level, not a piece-by-piece takeoff. Weights are plf × length. Radius is from the crane's walk line south of grid 1. Crane is a Liebherr LR 1300 SX, main boom plus luffing jib (No. 2316), walking a line 50' south of grid 1. Capacities interpolate the published reference chart for 88° or 83° main, 66' or 105' main boom, 135' and 174' jib columns, less 2 k rigging; the cab chart governs. Luffer working range 78° to 15°.

Ghost compares what is in place today against what the baseline said should be in place. Red is behind, green is ahead. With no baseline loaded it compares against the original dates, so any sequence you slip shows up immediately.
The sample steel and concrete schedules share one column set. Handoffs are found from Level and grid extents, never from predecessor IDs; the Preds column is only read afterward to see whether the planner tied them.
Column What it is ID, Activity, Trade, GroupGroup = erection sequence (steel) or pour (concrete). Rollup unit. LevelFND, B1, L1 ... RF. Elevated pours and deck releases must share a level to match. GridX0, GridX1, GridY0, GridY1Grid extents by label. Zero-width (a wall on grid E) matches anything touching that line. Start, Finish, Dur, PredsISO dates, workdays, ID;ID+2;ID-1. Type, Roletask / milestone. Role drives the rules and the drawings: raise, deck, release, pour, slab_release. RefOptional. Sheet numbers and member callouts for the group, shown when you tap a sequence or pour.
Rules
Concrete to steel. Every steel raise that starts on foundations needs every foundation pour whose footprint overlaps it. Available = pour finish + cure days (the OSHA 1926.752 75% letter). Need = raise start.Steel to concrete. Every elevated pour needs every steel release at the same level whose footprint overlaps it. Available = milestone date. Need = first activity of the pour (pour stops / rebar).Stacked trade note. A pour placed while ironworkers are still decking a higher level in the same footprint gets flagged, not failed.Crews. One ironworker gang of 8: on a raise day 6 on the iron and 2 hooking on in the yard, the rest to decking, then bolt-up, then weld-out. Concrete crews by activity: 8 carpenters forming, 8 rodbusters on deck prep, 10 finishers on pour day, 2 on cure and strip. Two trades in the same footprint on the same or adjacent level turn red.Pump and crane. The pump sets up on the north side at the pour's center and reaches to it (170' class boom). A pour day that overlaps a crane raise in the same bays gets flagged: shared airspace, hose and boom under the swing.Missing tie. If the needed activity (or anything in its group) is not upstream of the needer's predecessors, the handoff is marked. Dates can look fine today and still break the first time a pour slips.
Sample set
Grid A to J by 1 to 4, about 260' x 94'. Sector 1 (A to E) on spread footings with slab on grade (S1.11); Sector 2 (E to J) has a basement at 84'-0" with concrete walls and pilasters (S1.02, S2.03). Levels: L1 100'-0", L2 118'-0", L3 134'-0", roof deck bearing 150' to 152'. Columns W24x162/192 in the lower tier with W24x104 above (S2.01/S2.02), so erection runs in two tiers: basement lid first, tier 1 to L2, tier 2 to roof. SidePlate perimeter moment frames (W36x160 at L2, W24x76 at L3, W24x68 at roof), W18x35 (30) infill at 30' bays, W33x291 (110) girders cambered 3/4", unshored composite deck type D6R. Elevated pours break at D and G, so each middle pour straddles two erection zones. Numbers in parentheses on members are shear stud counts.
