Diagnosis and Inventory Updating of the Road Network in Bogota City.  This project involved three types of activities as follows

• Diagnostic and Inventory of urban road network (232.7 Km-carriageway).
• Diagnostic and Inventory of new urban roads to be included in the road network database (33 Km-carriageway).
• Diagnostic and Inventory of new rural roads to be included in the road network database (70.3 Km-carriageway). Unpaved roads.

This inventory, also included  geometrical and distresses inventory, measurements of roughness with Laser profilograph and measurement of deflection with Falling weight deflectometer (FWD) (measurements for urban roads), traffic study, core extraction to determine the layer thickness, georeferenciation of new roads among others.

Consultancy Services to develop the Phase II of Calibration of Deterioration curves in pavement structures in Bogota D.C.  The scope of the project included calibration test tracks with traffic study, geometric inventory, pavement distress inventory, measurement of roughness (IRI) using laser Profilograph RSp L5, measurement of deflection with Falling weight Deflectometer (FWD), core extraction to determinate the layer thickness.   In addition, it was determinated the diagnosis of tracks with calculation of MDR (modified distress rating) using PAVER Models and calculation of OPI (overall pavement index).

Complementation to the Inventory and Diagnostic of sidewalks, bycicle-routes (bikeway), median areas and street furniture and fixtures associated to the principal and intermediate urban road net of Bogota City.  This project included inventory and diagnostic of street furniture as bus stop, telephone booths, cans, lighting, tree protectors, benchs, etc, inventory and diagnostic of trees (geometric and physical condition).  Additionally, it was developed a database compatible with SQL server.

Inventory and data collection of the national pavement network road (aprox. 8.500 km) and all the bridges of the country. This inventory includes visual defects, deflections with NDT equipment FWD (Falling Weight Deflectometer), roughness measures and rutting with laser profilograph RSP, pavement thicknesses evaluation with georadar (GPR), traffic study, GPS, video images, geometry, drainage, vertical and horizontal signalling, walls, separators; additionally, it was signaling with milestone (Monumentation) georeferencieated with distance in kilometer, Development and implementation of a Road Management and Valuation System of the national network using World Bank model.

The project included the updating of the Inventory and condition of the Interurban Road Network (8500 km of paved and unpaved roads and 1384 bridges), carrying out a traffic study, and the development of an Integral Road Management System. Data collection included mainly NDT (non destructive testing)  measurement of deflections with FWD (Falling Weight Deflectometer), roughness measurement with RSP (Road Surface Profiler), distresses surveys, video inventory, soils study, inventory of geometry, drains, slopes and pavimento characteristics, traffic study (origin - destiny surveys) and a bridge inventory. 

The development and implementation of the Road Management System SAVIAL(Software), this software allows to establish a routine and periodic maintenance work plan considering as a fundamental element the existing budget and using HDM-4 models.

The project included: Inventory and data collection of all the paved Road network (2445 Km), the Unpaved network (3033 Km) and all the bridges of the country (1153) carrying out a traffic study and Development of an Integral Road Management System.  Data collection included mainly NDT (non destructive testing), measurements of deflections with FWD (Falling weight Deflectometer), Roughness measurements and rutting with Laser Profilometer RSP-L5, evaluation of pavement thickness with Georadar GSSI GPR, inventory of geometry, drainage, vertical and horizontal signalling, video images, GPS (Global positioning System), traffic study.

Besides, the Design, Development and Implementation of the Pavements and Bridges Management Computarized System; investment Program based on the HDM4 model (World Bank).  

Inventory of Bosa, Tunjuelito, Usme, San Cristobal, Ciudad Bolivar, Fontibon and Rafael Uribe Localities in Bogota City to evaluate and to prioritize the intervention strategies on the roads, in a lenght of 2317 Km-carraigeway.  The project involved geometric inventory, distresses inventory and data collection of different kinds; Analysing existing databases and systems, development of the Urban Road Administration System - SAVU.
