How to design an access ramp: the step by step procedure, reproduced with a BIM software and inspired by the Marble & Bamboo project
This week’s i nsight will analyze some architectural solutions from the Marble & Bamboo project, a contemporary residence located in the north of Madrid and built by A-cero studio.
In order to make a better use of a BIM software we will reproduce some planning stages that result of particular interest.
We will see how the access ramp connecting the basement floor to the main road has been created.
Marble & Bamboo: the architectural project
The Marble&Bamboo project is a single-family residence extending on a rectangular-shaped surface of 2800 sqm and surrounded by numerous oaks and pine trees.
The building shape has been adapted to the surrounding environment so to be able to preserve pre-existing spaces and vegetation.
The entire facade has been built in white travertine marble tiles and with bamboo elements creating a volume effect and a colour harmony.
Marble&Bamboo spaces architectural distribution
The construction is built on 3 levels.
On the ground floor there is the living room area, the kitchen, the closet, the main bedroom and a changing room.
The rooms on the back side of the residence are directly connected to the external area and to the swimming pool through a strip window that runs along the entire façade.
On the upper floor there are 3 bedrooms with en-suite bathroom.
The materials have accurately been selected for each area of the house.
An oak wood floor has been used in the private areas of the first floor for a warmer environment while white polished marble and more sober colours have been chosen for the common areas of the ground floor.
On the basement level we can find the other services and the garage connected to the main road through an access ramp.
The pedestrian access develops from the ground floor, while from the basement it is possible to access to upper floors through internal stairs.
The ramp path has a “S” shaped planimetric course going up towards the main road.
On the ramp sides, a not much sloping escarpment has been created. Vegetation has the purpose of holding the terrain movements and at the same time to embellish the surrounding view.
Let’s see how designers have faced this architectural solution using the BIM software Edificius.
Access ramp implementation with a BIM software
Let’s model the access ramp to the garage in the Edificius terrain section by selecting the “Ramp” object. In the relative editor we use the (radial) MagneticGrid2D to set up the width of the curved landing and the corresponding snap points.
In the properties tool-box we insert the ramp by setting up geometric parameters like width, internal radius and the curve angle. We can use several curved ramps with different directions (left sided/right sided) so to get a “S” shaped planimetric course.
In the 3D view we define the altimetric course of the ramp, first connecting the starting landing to the garage entry threshold and then to the ending one of the road.
In order to correctly position the ramp we use the Transparent terrain function allowing to temporarily hide the terrain so to connect the grips.
We perform an Earthwork that follows the ramp perimeter to generate the escarpments along its sides.
Let’s draw the perimeter of the terrain movement first in the shape of linear segments and then we proceed to their transformation in curvilinear segments by right-click mouse on the same segment and selecting the option Convert to Arc.
We add the escarpment using an automatic generating Add escarpment tool with the aim of connecting the ramp with the surrounding land and the building .
We thus modify the generated escarpment using the grips of each stretch in order to achieve the desired configuration.
Let’s insert small curbs on the side of the ramp using the Solid on Terrain tool. Let’s select a rectangular shape in the properties toolbox under the profile item.
Let’s then define its planimetric course in plan view and let’s set the elevation of the single segment from the 3D view.
Let’s assign a texture (grass) to the previously created escarpment.
We can complete the ramp reproduction inserting some vegetation on the escarpment selecting the models from the corresponding catalogues.
Subsequently we proceed inserting garden lamp posts on the side of the ramp as “3D Blocks”, properly picking the model in the BIM Objects Library BIM Object Library.
