  "task": "Model a villa ground floor roof beam and slab framing plan",
  "domain": "CAD",
  "application": "Autodesk Revit",
  "description": "Build a structural model of the ground floor roof framing for an east-facing residential villa (East Villa, 222 sq. yd), following the supplied dimensioned diagrams diagram_01.png, diagram_01_detail01.png and diagram_01_detail02.png. Work in imperial units (feet and inches).\n\nCreate a level for the ground floor roof and model the reinforced concrete beam grid with columns at the beam intersections shown. Every beam is 9\" wide. Use beam types for the three depths that appear: 9\"x18\", 9\"x24\" and 9\"x30\". Identify each beam by its mark as shown on the plan:\n- B1 (9\"x24\") along the north edge\n- B6 along the west edge: 9\"x24\" in the north bay and 9\"x18\" in the bays below\n- B11 / BR11 (9\"x30\") along the east edge\n- B5 and BR5 (9\"x30\") along the south edge\n- B4 internal east-west beams: 9\"x24\" in the west portion and 9\"x18\" in the east portion\n- B2 (9\"x18\") south of the staircase\n- B3 (9\"x18\") in the west bay\n- B7, B8, B9, B10 and BR10 (9\"x18\") as internal north-south beams\n\nSet out the bays to the clear dimensions shown. The northern bays are 13'-2\", 4'-7\" and 12'-8\" wide. The central row is 13'-2\" and 18' wide. The southern bays are 5'-6\", 10'-4\" and 14'-7\" wide. Vertical spans include 18'-3\", 7'-11\", 9'-8\", 10'-5\", 16'-6\", 12'-7\" and 15'-1\".\n\nModel the roof slab over the framing with these features:\n- A staircase opening in the north-east bay, approximately 12'-8\" by 10'-5\".\n- Two 12\" sunken slab areas: one in the 4'-7\" bay in the north and one in the 5'-6\" bay in the south-west.\n- Slab projections at beam top along the south edge: a 5\" projection over the 18'-6\" western length, and a 12\" projection over the 16'-4\" eastern length that returns up the east side for 15'-1\".\n\nTag the beams with their marks and sizes and dimension the bays in the roof framing plan view. Include North, South, East and West elevation markers around the plan.",
