Private initiative, central Costanera motorway, phase II studies

Sector: Transport
Client: OHL
Years: 2014 – In progress
Description: BAC is currently drafting the advanced preliminary design of the private initiative for the central Costanera motorway, which includes the engineering works necessary before the invitation to tender for the concession.

The main objective of the central Costanera motorway project is to solve the traffic problems between the Sur Oriente sector (communes of La Florida, Puente Alto, Pirque and San José de Maipo), including the communes adjacent to the alignment of this road (Peñalolén, Macul, San Joaquín, San Miguel and Pedro Aguirre Cerda), and the central and western areas of Santiago de Chile.

Therefore, this project plans to extend the central Costanera motorway towards the city centre and up to its connection with the future Américo Vespucio Oriente motorway, which, together with the Central and Sol motorways, will ensure fast and fluid transit through any point in the city.

The total length of the alignment is around 21.6 km.

Construction of the Avenida Pie Andino connection

Sector:   Transport
Client: SERVIU (Department of Housing and Town Planning)
Years: 2013 – 2014
Description: The project comprised opening up and extending the current profile of Avenida Pie Andino by providing a dual carriageway from Calle Eyzaguirre to Avenida Domingo Tocornal, where it connects with Avenida de México in the Puente Alto commune, thus improving the latter’s transport links.

The characteristics of the project required the participation of several specialisms, such as: Civil Engineering (Soil Mechanics, Hydraulic and Road Engineering), Structural Engineering, Transport, Electricity and Urban Design. Their implementation was coordinated as the project progressed.

Improvement of public transport corridor in intermediate ring road

Sector:   Transport
Client: SERVIU (Department of Housing and Town Planning)
Years: 2013 – 2014
Description: The aim of the project was to optimise the current capacity of the corridor formed by Las Rejas Norte and Avenida Sergio Valdovinos by improving public transport facilities as effectively as possible. One of the project outcomes is an improvement in the quality of life of the residents and users of the system since the daily journeys they need to make will now mostly take less time. Consequently, the outline proposal focused not only on detailed engineering for the specialisms directly related to the project (such as road network and transit), but also on urban design, lighting, rainwater drainage, etc., which, as a whole, besides the profile for the bus-only corridor separated from private vehicle lanes, provides spaces for pedestrian traffic and landscaping of green areas in keeping with the safety requirements and standards that a project of this magnitude requires.

The corridor in question is located in the Nor-Poniente sector of Santiago and it is approximately 2.5 km long in total.

Construction of the Sargent Menadier corridor: Avenida Santa Rosa – Avenida Concha y Toro section

Sector: Transport
Client: SERVIU (Department of Housing and Town Planning)
Years: 2013 – 2014
Description: The project consisted of continuing the Sargento Menadier corridor from Avenida Santa Rosa in the west to Avenida Concha y Toro in the east by means of a dual carriageway connecting sections that had previously been interrupted. It included the preparation of strips of land for possible future development, profile extensions, a bridge over the Southern Access Motorway to Santiago and a viaduct crossing a quarry. The total length of the project is approximately 5 km.

Two noteworthy structures included in the design are a viaduct over the southern access to Santiago motorway, which is approximately 194 m long, and a bridge for crossing a quarry, which is around 55 m long.

The project involved a series of sub-projects associated with each of the specialisms to open up, connect and extend the existing profile of this corridor. These included: changes in utilities, traffic lights, lighting, pavement, geometric design, landscaping, etc.

Padre Renato Poblete River Park Project

Sector:   Transport
Client: Ministry of Public Works
Years: 2011 – 2012
Description: The aim of the Padre Renato Poblete River Park, an emblematic project for the city of Santiago, was to make the Mapocho River accessible to residents by constructing a large urban park around an artificial branch of this river.

The BAC team’s participation focused on the detailed engineering of the park, including some special hydraulic works, such as the design of inflatable dams in the course of the Mapocho River, diversion works towards the river branch inside the park and works to return the water to the river. In addition to the engineering works, we designed all the equipment, buildings and facilities for the park in coordination with the architectural team from BOZA Arquitectos.

Engineering project. Improvement of public transport corridor, San Pablo. Sections 1 and 2

Sector: Transport
Client: SERVIU (Department of Housing and Town Planning)
Years: 2013 – 2014
Description: The project consisted of the detailed engineering of the specialisms required for the complete overhaul of a public transport corridor in Avenida San Pablo, along the stretch between Calle Antonio Ebner in the east and the Américo Vespucio motorway in the west. It is approximately 8.3 km long and crosses three communes in Gran Santiago.

The characteristics of the project required the participation of several engineering and urban development disciplines, such as: Civil Engineering (Soil Mechanics, Hydraulic and Road Engineering), Structural Engineering, Transport, Electricity, Architecture and Landscaping, etc. Their implementation was coordinated as the project progressed.

The corridor in question is located in the Nor-Poniente sector of Santiago and it is approximately 2.5 km long in total.
