El Cemsa se desarrolla en tres manzanas independientes con circulación compartida por medio de una gran plaza central de 550 metros lineales que atraviesa los tres conjuntos y un ancho de entre 20 y 24 metros la cual comunica peatonalmente los accesos a los edificios y los locales en los primeros pisos donde están situados restaurantes, cafés, bancos y servicios complementarios. Además, conecta peatonalmente el centro comercial Gran Estación y el edificio de la Gobernación de Cundinamarca. En cada súper manzana la plaza central cuenta con cerca de 4.000 m² y bajo cada una de ellas hay tres sótanos de parqueo con una capacidad aproximada de 2.500 cupos en cada una.[10].
Avianca Tower
As part of the growth plans of the Colombian airline Avianca, the company's directors decided to move its headquarters to this real estate complex that began construction in 2007 and ended in 2009. This was the first building to be inaugurated at Cemsa. Parking of the vehicles of the tower owners and visitors. On the first floor there are 8 commercial premises directly connected to the central square, on the second floor there is a large auditorium serving Avianca and the rest of the floors are used for the offices of the company that owns the entire building.[1].
CCI Tower
The Colombian Chamber of Infrastructure brings together several companies in charge of the construction of roads and infrastructure in general in Colombia. The entity made the decision to bring together in a single building 20 of the companies affiliated with it in the second Cemsa tower, which began construction in 2008 and ended in 2010.[1] The building is 10 stories high, has three basements for 499 parking spaces for the vehicles of the owners of the tower and visitors. On the first floor are the commercial premises connected directly to the central square. The tenth floor facilities have conference rooms and virtual offices for members who require this service.
The building has a bioclimatic design on the façade, whose glass reduces light and heat, which reduced investment in cooling equipment and energy consumption. Additionally, it is the first business building that uses technology proven by the industry, with eight micro gas turbines that produce the electrical energy and air conditioning that the building requires.[12] Among the infrastructure companies that have their headquarters in the building are the National Hydrocarbons Agency, Autopistas del Café, CCFC, Civilia, Coviandes, Conconcreto, Coninsa Ramón H, Convel and Grupo Odinsa, among others.
Argos Tower
Those that were known in the design as towers 3 and 4 became the Argos complex or tower, a structure that from the outside appears to be a single building, but nevertheless the operation of these towers is independent. The Argos tower became the third and fourth Cemsa tower that began construction simultaneously in 2009 and finished in 2011.[13] The building is 10 stories high, has three basements for 836 parking spaces for the vehicles of the tower's owners and visitors. On the first floor are the commercial premises connected directly to the central square. The inauguration of this tower served to complete the first central pedestrian plaza of the three that make up the project.[1].
The construction of towers 3 and 4 received the LEED pre-certification provided by the United States Green Building Council (US Green Building Council), which is awarded to works that contribute to sustainable development. The precertification was obtained because the towers capture rainwater for use in bathrooms and irrigation of green areas, the towers were equipped with low-consumption urinals and toilets, equipment with low energy consumption such as intelligent elevators was used, the lighting is based on motion detectors and the extraction of gases from the basements is activated by concentration sensors.[5].
Colciencias Tower
Towers 7 and 8, also known together as the Colciencias tower, are located on the block where the Grand Hyatt Bogotá Hotel and the convention center that Cemsa will have are being built. The "L"-shaped building is made up of three basements with capacity for 782 vehicles and 16 floors of offices, unlike the previous towers inaugurated that have 10 floors each. The design of the building is bioclimatic like that of the Argos tower. The structure has a large lobby for the two towers that operate independently, each with its own reception and elevator system. They have a central cooling system, natural ventilation and efficient windows. On the roof of each tower, green areas with gardens and terraces were installed with access for officials and employees of the offices that use the towers. The first floor has commerce and corporate use spaces that serve the towers and the public that circulates through the second pedestrian plaza.[14].
The foundation and structure of the tower were built in reinforced concrete following the requirements established by the Colombian Regulations for Earthquake-Resistant Construction (NSR-10), the seismic microzoning of Bogotá and the recommendations of the soil study. The foundation is made up of a set of slab and piles, the slab controls bottom forces and the piles transmit the loads to the ground at a depth of 50 meters. Each tower has evacuation stairs, one of which is pressurized with direct exit to the outside.[15].
The construction of towers 7 and 8 or Colciencias tower carried out the LEED certification process by reducing environmental impacts and reducing energy consumption. Hydrosanitary facilities were implemented for the use of rainwater with the aim of reducing operating costs, all equipment is integrated and monitored by a security and automation system, the windows are efficient and ventilation is natural, in addition, the towers' elevators operate with a system of high efficiency motors that reduce energy consumption.[1].
Hotel Grand Hyatt
In June 2012, the directors of the hotel firm Hyatt signed an agreement to build the first Grand Hyatt hotel in Colombia and the third in Latin America after those built in Santiago de Chile and São Paulo, and in June 2014 construction of the five-star hotel began,[16] Finally, the hotel was inaugurated on August 29, 2018.[17].
The hotel has 373 rooms on 14 floors and 850 parking spaces in 3 basements. It also has a 1200 m ballroom, two restaurants with views of the eastern hills "Cerros Orientales (Bogotá)"). It also has a swimming pool, spa "Spa (health)") and heliport. The hotel was designed to contrast with the rectilinear office buildings found at Cemsa, and is configured as an ellipse with an open atrium in the center. The building is clad in a high-efficiency glass and aluminum curtain wall, with solid stone panels at the base and ends of the building.[18].
The foundation of the Grand Hyatt Hotel consists of 516 piles with diameters between 0.60 m and 0.80 m, it also has 364 m of perimeter screens with a depth of 20 m and 21 units of bars with a thickness of 0.40 m and a depth of 45 m.[19] It was built in the development of the second block of Cemsa. The cost of the work was approximately 250 million dollars and it has a total constructed area of 78,000 m.[20].
Towers 5 and 6
In May 2024, construction began on the towers initially named 5 and 6. These towers are located at the western end of the Cemsa complex.
The 16-story project will integrate sustainable architecture by architect Rafael de la Hoz. It will have a total of 24,977 m built, 800 m of common areas, 550 m of green areas on the terraces, 550 m for commercial spaces on the first floor and around 500 parking spaces. It will have a BMS control center (Building Management System) that will supervise each subsystem of the towers such as the backup power supply, the control of mechanical ventilation or the operation of the elevators.
The construction of the towers is in the process of LEED certification given the sustainability characteristics that it will have such as low-emissivity glass that protects occupants, optimization of natural light, mechanical ventilation with filters and UV lamps for cleaning and better air quality, efficient air conditioning for common areas, reuse of rainwater in toilets and 100% of irrigation, bicycle racks and electric vehicle charging infrastructure.[8].
Convention Center Project
In December 2013, the District Institute of the Arts (Idartes) announced that a 40,000 m² cultural complex is planned to be built in the second block of Cemsa. It has been announced that it would have two auditoriums, one with capacity for 1,400 chairs and the other for 400 chairs. There would also be a restaurant, a gallery, a store specialized in culture in addition to the service areas required for the operation of the convention center. The start date of the works has not yet been defined.[7].
