I. FORMWORK PLAN
2
It indicates the shape, dimensions and positions of thestructural elements that make up the slab.
It represents the plan view of the slab at the level of a
horizontal section through the vertical elements.
Sectioned elements (columns) should be hatched.
The vertical dimensions of the plate and beams are
indicated by cutting some transversal sections that are
then rotated into the plane of the slab. The horizontal
sections should be rotated downwards, while the vertical
sections should be rotated to the right.
It should show all dimensions that are necessary to
indicate the position of structural elements in respect to
the axes of the building.
It should show all the dimensions of the formwork panels
for plate, secondary and main beams.
The elaboration stages are:

II. REINFORCEMENT PLAN

It is obtained by representing the reinforcement over theformwork plan. The interior dimensions are no longer
represented in order to clear the space.
In order to be viewed, the rebars are represented as
rotated in the plane of the slab. The rebars are represented in the same order they are
placed inside the formwork.

II. REINFORCEMENT PLAN
12
The top rebars should extend on each side of the beamfor a distance of 1/4 from the largest adjacent clear
spans.
The inclined rebars start to descend at a distance of 1/5
from the respective clear span.
Distribution reinforcement, at least 4φφφφ6/m, has to beprovided perpendicular on the main reinforcement.
!!! At the top side of the slab, the distribution reinforcement will be provided
only in the zones where top main reinforcement is present (in order to create a
mesh of rebars)

Top reinforcement, at least 5φφφφ8/m OB37, should beprovided perpendicular on the main beams in order to
resist the negative bending moments developed on the
long direction. It has to extend on both sides of the main
beam for a distance of 1/4 from the clear span on theshort direction of the slab.

The dimensions of all straight segments of the inclinedrebars should be provided.
The slab reinforcement plan should also contain the table
of reinforcement that provides the main characteristics ofall the reinforcement marks: the diameter, the length and
the geometry of the rebar, the steel grade and the
number of identical rebars.
At the bottom side, the table of reinforcement has topresent the summation of the lengths of all reinforcement
marks for each diameter and the total quantity of
reinforcing steel.
