Integrated testing, thermography and commissioning

The commissioning and testing service of the installations aims to certify that an installation was properly delivered by the installers and in full operation, in this stage individual tests, performance tests and thermography of the equipment and systems that make up the infrastructure are carried out. This process includes performance, start-up tests, transfers, alarms and simulation of operation at full load with or without the use of a load bank.

BIM Management, Virtual Reality (VR) and Augmented Reality (VA)

Identification and management of clashes
Compatibility, budget, planning, or management facilities
Model development for visualization in virtual reality (VR)
Model development for visualization in augmented reality (AV)
Development and planning of BxP (BIM Execution Plan) identifying model configurations and levels of detail (LOD)

Survey and 3D Scanner

We have a survey service through a scanner capable of raising 3D, color images of all existing installations
It features high speed with extra-long range, it can scan objects up to a range of 330 meters, even in direct sunlight
With its built-in GPS receiver, the laser scanner is capable of correlating individual scans in post-processing, making it ideal for topographical survey-based applications.
3D scan data can be easily imported into all commonly used software solutions such as architecture, civil engineering, construction, topography, and facility surveys

Management and monitoring of works with Power BI

Managing the triple constraint: time, cost, and scope + quality
Management of disbursement curves / “S” Curve
Status reports
Construction and monitoring of schedules and deadline-reduction techniques
Use of “tayloring” techniques, that is, we believe that the best management is the one that unites the best existing methodologies, tools, and templates to what the client needs; always depending on the size of the project/work to be managed
Elaboration and monitoring through the Power BI tool, of all management variables, using the added value technique
Monitoring of change requests
Identification, analysis, and responses to risks and opportunities – SWOT
Stakeholder management (power x interest)

CFD study - (computer fluid dynamic)

LZA, among its services, performs fluid dynamic simulation through the 6 Sigma room software

Powerful and innovative

Undoubtedly, an important tool for diagnosing the operation and system performance of an environment mainly with high densities of powers - of a site or improve the performance dramatically. The most common application of this tool has ultimately reached large capacity data centers and LZA Engenharia has achieved results that guarantee efficiency, reliability and availability even in the design phase of the project

For indoor and outdoor environments

You can simulate intake and exhaust temperatures, pressure, humidity, air distribution, equipment efficiency, zone of influence, among other features related to air conditioning. It is possible to configure CRAH, Chiller, Cooling Towers, Floor Grilles, fans, sensors, controllers, filters, heat exchangers, pipes and ducts connected to the system

6Sigma + VR

6Sigma room also allows the creation of videos with air movement according to equipment in operation, report with video and the most interesting: the user can "navigate" the site and simulation through the plug-in VR View (Virtual Reality)

Projects with certifications

LZA Engenharia is the company that has most certified data center projects throughout Latin America. There are more than 50 projects with the Uptime Institute (American institute that analyzes the reliability, availability and security of data centers) and also some with TÜV Rheinland. In addition, the company also has approved projects taking into account sustainability certifications, such as: LEED, Aqua and CEEDA. Combined with the best sustainability practices, we are constantly improving and tuned in to remain pioneering when it comes to investing in ESG policies (sustainability, social impact and governance), and how the Brazilian market will adhere to zero emissions / carbon credit in their facilities in the future
