What was CH3's role in the São Lourenço II complex?

At the São Lourenço II complex, CH3's involvement began long before construction. The challenge, taken on together with the real estate developer, was to carry the development from the drawing board to final delivery, meeting every requirement.

Before construction: feasibility and approvals

The initial stage was handled by CH3's technical specialists: a market feasibility study, macro analyses of phased construction, and municipal, environmental and legal approvals. This work began in 2010 and took a year and a half before construction could start.

Construction

Infrastructure work on the site of almost 1 million square meters began around 2014, including the dam and the road system, applying the principles of diverting water and returning it to its natural bed.

Next came the logistics warehouse, with more than 80,000 m² of built area. The job mobilized hundreds of technicians, engineers, foremen and workers to move tons of earth and erect precast, composite and concrete structures, columns and metal roofs with standing-seam panels. The floor was laser-leveled, with above-average flatness.

For the water, sewage, air and energy systems, CH3 built:

• a water reuse system for washing the yard, landscaping and toilet flushing
• 5 kilometers of sewer line to the city's treatment plant
• a system providing three air changes per day, by density, with natural thermal comfort
• a daylighting design that cuts energy consumption by up to 30%

Delivery of the first phase

The first phase opened in September 2022 and includes, in addition to the warehouse, the 3,000 m² administrative building, two armored gatehouses, a certified helipad, parking and an outdoor truck yard. CH3 led the whole project from start to finish, guided by the principles of the leading certifications, such as LEED.
