Contracting models
ISG manages the entire project, from the beginning, to delivery of the datacentre, to ensuring our client is ready to host IT equipment, always under a planned commitment.
In this construction model, all costs are ‘on the table, open books’, meaning that the client has the option to directly purchase equipment after receiving consultancy from ISG on the best technical and economic options available to them.

Our work
The works developed by ISG are as follows:
The different construction systems shall be adapted to the needs of the datacentre.
We must mention for the High Security Data Processing Centres, the combined-protection precincts, high material consistent and high electromagnetic, physical and fire safety systems.
In ISG, we address the Construction of Data Processing Centers (DPC), Housing and Hosting Centers, Telecommunications Nodes, Switching Centers, Call Center, Television Studios, Clean Rooms and Laboratories, all of which are framed as "MISSION CRITICAL" FACILITIES ", where the Continuity of its Operation is Critical for the Importance of its service.
ISG believes that electrical panel data monitoring is crucial in the panel design for an electrical consumption control, including the final distribution panel PDUs, where we can integrate a consumption reading for each output individually into the control system.
The existing uninterruptible power supply units are adaptable depending on CPD magnitude, flexibility and growth, and the response time from the facility network switching operations.
Among the conventional static systems, the modular systems of 10, 20, 30, 40 and 50 kVA are noteable, and can be expanded in the same UPS cabinet to 250 kVA, without system voltage drops. Ideal for average CPDs with scalable growth.
Dynamic UPS units with functioning based on kinetic power storage through an inertia system, are an alternative to conventional-battery UPS units.
These systems are worth mentioning for their low maintenance and precise coordination with the ancillary supply switching systems.
ISG studies various air conditioning systems and is always looking for the best technical and economic option adapted to the data processing centre.
The type of system is based on size, space availability, access, geographical location and other factors.
Air-refrigerated direct expansion systems
Water-refrigerated direct expansion systems (dry cooler)
Water-cooling systems with free cooling option
Mixed systems with separate cooling units, direct expansion and water system
Indirect free cooling systems, through exchangers
Direct air free cooling systems
Absorption-machine water systems
The advanced early fire detection systems must install CPDs, as their high sensitivity and fast response provide an efficient fire preventive action.
The use of new inert and synthetic gases, such as NOVEC, which are innocuous for people and the environment is part of the facilities built by ISG.
The choice of gas depends on the costs and availability of the spaces for the location of gases.
Water-mist extinguishing systems are an alternative to gas extinguishing systems, as they have a higher initial installation cost and lower repairs cost. These systems are advisable for big CPDs where each discharge may require a high repairs cost.
Other complementary systems, such as smoke-washing, are systems that avoid the distribution of smoke through the facility in case of fire, via a suction system and pipeline route through the raised floor, which extracts smoke as fast as residual water.
Systems against intrusion, closed circuit television systems (CCTV), advanced biometric technology access control systems, highly precise dew point detection systems, and any facility that helps the functioning of the CPD are being increasingly used nowadays.
Access control systems interconnected with lighting systems provide the power-on and off of the rooms in order to save energy.
With a test protocol standard, ISG tests and checks that all facilities operate correctly, and ensure that the facility’s power rate is real. These include:
Real UPS discharge tests
Real air conditioning load tests
Switching test
Emergency system checks
Extinguishing gas discharge
ISG’s commitment is to fully document and certify all performed facilities, including the follow-up and necessary regulations with official bodies.
