2. Viability study of the urbanization project in the 'Vereda de San Cayetano, La Calera (Colombia)’
Purpose of the Study
 Urban development design with 52 parcels
 A study of viability is needed to check the proper design of roads and the accesses to the
parcels due to the rough ground
Original Design
3D View

3. Viability study of the urbanization project in the 'Vereda de San Cayetano, La Calera (Colombia)’
 The Road 1, the Road 4 and the Main Road have been modified to adjust to the maximum
to the contour lines
 It has been done a detailed study of the surface with Civil 3d to check how it affects the
development and apply solutions
Modified Design
Road 1
Road 4
Main Road

4. Viability study of the urbanization project in the 'Vereda de San Cayetano, La Calera (Colombia)’
 It has analysed all roads doing longitudinal and cross ground sections, keeping in
mind the plots accesses
 It has proposed an grade line to each road trying to respect the Colombian Roads
Regulation who establishes as maximum slope 18% for tertiary roads and sheer
ground
Modified Design

 More than 150 meters difference between the
Eastern and Western side of the residential area

Road 1
Road Axis with Accesses Longitudinal Section
 Two study axes, one flows from the beginning of the road until the centre of the
roundabout and the other one is on the roundabout to study the two accesses
 We put stations every 20 meters and in the accesses to parcels
 Depending on the cut or fill height, we design retaining wall to avoid landslides
 In the longitudinal section we observe the height of cut or fill necessary in the centre
of the road

Cross Section: 0+040.00 Road Section Detail
 We can establish where is needed a
retaining wall checking the cross sections
 There are designed when the height is
over than 1,5 meters

 Circular axis of half roundabout
sited in the edge of the sidewalk

Road 2
Road Axis with Accesses Longitudinal Section
 Important fill zone at the beginning of the road due to the influence of the main road
Roundabout Cross Section: 0+008 Cross Section: 0+120.00

Road 3
Road Axis with Accesses Longitudinal Section
 8 accesses from the road 3 because of the grade line is close to the surface line
Roundabout Cross Section: 0+003 Cross Section: 0+040.00

10. Viability study of the urbanization project in the 'Vereda de San Cayetano, La Calera (Colombia)’
Road 4
Road Axis with Accesses Longitudinal Section
 High volume of cut ground due to the Main Road
Roundabout Cross Section: 0+020 Cross Section: 0+000.00

Main Road
Road Axis with Accesses
 The Main Road, with 1,300 meters
of length, is covering completely
the area overcoming 150 meters
of difference of elevation
 There will be problems to design Forest
Area of the road due to the high slope
 The roundabout is modified from the
original design

Main Road
Longitudinal section
 The Main Road, with 1,300 meters of length, is
covering completely the area overcoming 150
meters of difference of elevation
 From 920 until 1,020 meters there is an important
ground fill, being maximum at 1,000 meters, more
than 5 meters of height
 From 1,020 until 1,080 meters there is an important
ground cut, being the maximum 3 meters of height
 To solve this problem it will be necessary to build
important retaining walls in the forest area

Main RoadCross section: 1+000
 Necessary a retaining wall of 7 meters
in the fill side
Cross section: 1+040
 Necessary a retaining wall of 6 meters
in the cut side
Cross section: 1+040
 Access to R28 house from the
Main Road
 Necessary retaining walls to
keep the ground in both sides
