FOUNDATIONS (GROUND BEAM)

A ground beam is a reinforced concrete beam for supporting walls, joists, etc., at or near ground level, itself either resting directly upon the ground or supported at both ends by piers.

In Revit, the ground beam is drawn using a Wall family which provides quantity, length, area and volume measurements to SkyBIM’s Product Editor.

Example: Ground Beam 150mm wide x 730mm deep

Typical Ingredients for Ground Beam

Excavation in earth (730mm deep)
Volume = Foundation wall length (from Revit) * Excavation Width (enter manually) * Excavation Height including 50mm Thick Blinding (enter manually) See SkyBIM’s Consumption Formula Editor

Excavation in hard rock based on 5% of volume of excavation
Volume = Excavation volume * 5%

Excavation in soft rock based on 2% of volume of excavation
Volume = Excavation volume * 2%

Cart excess earth from trenches
Volume = Foundation Wall Length (from Revit) * Excavation Width (enter manually) * Excavation Height including 50mm Thick Blinding (enter manually)

Backfilling to trenches
Total Excavation Volume – Total Volume Carted Away

Back excavation in earth for working space
Area = Sides of Foundation Wall Area (from Revit) * 2

Risk of collapse to sides of excavation
Area = Sides of Foundation Wall Area (Revit) * 2

30 Mpa reinforced concrete in foundation ground beams
Volume = Revit Volume

15 Mpa mass concrete in blinding 50mm under foundation ground beams
Volume = Foundation Wall Length (Revit) * Ground Beam Width (Manual) * Blinding Thickness (Manual)

Rough formwork to sides of ground beams
Area = Sides of Foundation Wall Area (Revit) * 2

Mild/High tensile steel reinforcing to concrete ground beams
KG = Ground beams concrete volume x 150kg = total reinforcing to ground beams

ROOFS (CONSTRUCTION AND ROOF COVERING)

Basic Roof with Double Roman Concrete roof tiles

Roof

New house roofs are mostly framed with trussed rafters, although rafters are still used. Office and commercial buildings usually have a reinforced concrete slab, while factories and warehouses use portal frames or girders with northlights. Roofs can be flat or pitched and have many different types of roofing.

Roof Covering

Roman tile is a British single-lap tile. The single Roman tile is not standard and has one waterway. The double Roman tile is standardized and has two waterways separated by a central roll.

In Revit, the roof truss is drawn using a structural truss family which provides a count and length measurement to SkyBIM. In addition, the roof covering is drawn using basic roof family which provides pitched area measurement to SkyBIM.

Example: Basic Roof with Double Roman Concrete roof tiles

SkyBIM Product Editor Ingredients

Double Roman concrete roof tiles
Sloping Area = Revit Basic Roof Area. See SkyBIM’s Consumption Formula Editor.

CEILINGS

6.4mm Thick Herculite Suspended Ceiling

The visible upper surface of a room, which can be an open slab soffit, or any type of dry lining fixed to floor joists or ceiling joists, or a suspended ceiling, or a stretched covering. A roof light can form part of a ceiling. Ceilings are usually painted white or a light colour.

In Revit, the ceiling is drawn using a Ceiling family which provides count, area and perimeter measurement to SkyBIM.

Example: 6.4mm Thick Herculite Suspended Ceiling

SkyBIM Product Editor Ingredients

6.4mm Thick Herculite ceiling fixed on 38x38mm Brandering
Area = Revit Room Area

EXTERNAL ENVELOPE (Window)

Durowin Window, size 1 022 x 949 mm high

A window has an outer frame, a sash, and its glazing. There are many types: hinged casements, vertical sliding sash windows, horizontal sliding windows, pivoted sashes, tilt-and-turn windows, vent-lights, hopper windows, etc. They are mainly of timber, aluminium, steel or PVC.  Factory – finished windows are usually made to go in a sub-frame.

In Revit, the window is drawn using a Window family which provides a count measurement to SkyBIM.

Example: Durowin Window

INTERNAL DIVISIONS (Internal Hollow Core Door)

Internal 44mm Thick Hollow Core Door, size 813 x 2032mm high

The doorset in a wall opening, for walking through, or on a cupboard. External doors are used for access and internal doors for communicating. Single and double doors are usually side-hung, but there are other types, e.g. flexible, sliding, swing, revolving, folding, and up-and-over. Special doors are used against fire or smoke.

In Revit, the door is drawn using a Door family which provides a count measurement to SkyBIM.
