Construction project-management skill

The Construction skill turns Nexma into a project-management platform for built infrastructure. It models phases, activities, resources, and dependencies, and schedules them under capacity and budget constraints.

What it covers

• Entities. Project, Phase, Activity, Resource, Material, CostItem,

Risk, Schedule. Each carries typed properties (duration, cost, crew size, material quantity).

• Relationships. TaskDependency (FS, SS, FF, SF), ResourceAllocation,

MaterialRequirement, CostAssignment.

• Constraints. Schedule feasibility under resource capacity, budget caps per

phase, safety-clearance rules between concurrent activities, weather windows for outdoor work.

• Constants. PMBOK process areas, RSMeans cost defaults (where licensed), OSHA

safety-clearance tables.

• Layer config. Project sites as 3D extruded footprints, activities as colored

blocks on a Gantt overlay, crews as labeled markers on the map.

• Toolbar tools. Generate schedule, level resources, run critical-path analysis,

export Gantt or P6 XER.

Typical workflow

1. Scope. Define the project polygon and the phase structure.
2. Activities. Bring an existing WBS or have Jax decompose phases into activities

from a template library.

1. Generate. Ask Jax: "Schedule this project assuming two crews, six-day weeks,

and weather windows from the local forecast. Hold the budget under $4.2M."

1. Inspect. Click activities for predecessors, lag, and float; hover crews for

utilization across the schedule.

1. Refine. Move activities, change crew size, adjust dependencies — Jax re-runs

CPM and reports new completion dates.

1. Validate. Resource-leveling check, budget rollup, safety-clearance audit.
2. Export. Microsoft Project XML, Primavera P6 XER, or CSV from `Project →

Export`.

What Jax is good at, in Construction specifically

• Schedule generation under capacity constraints with calendar-aware leveling.
• Critical-path analysis with float reporting and risk-weighted alternatives.
• Material take-off from drawings and quantity rollup against unit costs.
• Safety-clearance audits between concurrent activities on the same site.

Standards

PMBOK 7th edition, ISO 21500 project-management terminology, OSHA 1926 construction-safety rules (US).

What it does not do (yet)

• BIM model authoring (consume IFC inbound; no native authoring).
• Detailed fabrication-shop drawings.
• Subcontractor procurement workflows.
