Our Building Service Team of skilled electrical engineer for such these services, this allows us to provide our clients with environmentally sustainable, world-class designs and expert electrical engineering. Our services are offered at different stages: from project inception to final design, site technical support and completion.
Low voltage (LV) systems, distribution boards and switchgear
Lighting System
Indoor & outdoor Lighting systems are provided based on substation design criteria and the submitted design shall achieve the optimum illumination requirements for each indoor space and outdoor area.
Detailed drawings for lighting system will be prepared based on the lux study calculation report for each space or outdoor area.
The details & technical descriptions of each luminaire shall be attached with the lux study documents and all proposed luminaires types shall be matched with project requirements.
Luminaires types are selected based on the application and space requirements.
Small Power Distribution
Design drawings for Power network are prepared for each building and outdoor area according to project technical specifications with considering maintenance requirements.
Mechanical power supply shall be considered in power network design drawings according to mechanical design requirements, equipment list shall be prepared with all necessary information to complete the design of power network.
Cables Sizing Calculation
Such this calculation shall consider and cover the project technical specifications
Some information shall be provided by site team such as thermal resistance of native soil to consider these values during cables sizing calculation in case of direct buried cables.
The cables calculation report shall be done in accordance to relative international standards and verified cables calculation software.
Main Distribution Board & Sub-Distribution Loading Calculation Schedules
Detailed documents/drawings shall be provided according to building design package with indicating more information about panel total connected loads and demand loads between branch circuits as per project design criteria.
Communication lines, telephones and IT networks (ICT)
Voice and Data System
The voice system shall be based on IP telephony technology or other conventional system as per project technical specifications.
The scope of work is extended to passive network components and all active component.
The voice and data system shall cover all project areas as indicated on design drawings.
The extent of work of the network is described by the project documents as indicated on Drawings, in schedules and on single line diagram of the project
Public Address
The public address system (PA) shall be used to provide background music and public announcements.
The public address system shall be also used to broadcast paging live messages and mute the Background Music (BGM).
The public address system shall receive control signals from fire alarm system in case of fire.
Voice evacuation messages and alarm tons shall be broadcasted by the Public Address system using the appropriate hardware and software modules required for interfacing between the Fire Alarm (FA) and the PA systems.
Interface equipment shall be included in the public address system to communicate with the FA system for receiving command of announcements. Supervisory signals shall be sent from the PA to the FA to confirm healthy situations or indicate fault.
The public address system main component as the following:
- Audio Matrix and workstation
- Preamplifiers (if required), power amplifiers
- Program sources (CD player, double cassette, tuner and paging microphone)
- Loudspeakers
- Monitor module panel
- Racks
MASTER CLOCK SYSTEM
In this section, we shall make a solution to maintain correct synchronized time and transmit time-correction signals over dedicated system wiring from a master clock to PCs connected to the structured cabling network or Secondary Analog Synchronous Clocks.
In substation Project, it’s controlled by substation control system through GPS antenna as we have level of remote substation control which controlled by country electricity national grid authorizations.
Lightning protection
Please note that the risk assessment report is very important to minimize the total cost of this item and the required factors is various as per project location and country regulations
Earthing system
Soil enhancement material may provide as proper solution to achieve a lowest ground resistance as per project requirements and relative standard, such as LOW‐RESISTANCE EARTHING COMPOUND & BENTONITE.
Fire detection and protection
The provided fire alarm system shall be suitable for type of occupancy as defined by international standards and as per the local fire Authority for each country.
The fire alarm system shall be used to detect early start of fire in any location in the project and initiate the appropriate annunciation, alarm, interlocking and counter measures commands as described in the project design criteria.
The Fire Alarm system shall supervise all the functions of the equipment and devices including the connected safety related systems such as firefighting monitoring and control equipment, etc.
Fire Alarm solution shall consider Audible alarms, voice evacuation message and visual strobe lights will be used for annunciation.
The Design of Fire alarm system shall be interfaced with Public Address system, Elevators, smoke control equipment, emergency power systems and all other related systems.
Also, design drawings/documents shall include all necessary hardware and software for integrated complete and operable system in accordance with the requirements of the project.
Security and alarm systems
CCTV
The hybrid based (IP / Analogue) CCTV system shall be used for security surveillance having color video cameras.
The CCTV System shall cover project areas as indicated on the detailed drawings which prepared based on the project technical specifications.
The proposed solution of video cameras locations shall be at suitable positions, which make them cover the intended fields of vision.
Also, during the design stage, it’s a must to verify spaces for equipment, based on actual dimensions of equipment furnished.
CCTV system shall be interfaced with security systems, and all other related systems.
INTRUSION SYSTEM
The intrusion detection system is a security system, which shall control access to certain areas and give alarm in case of unauthorized activities in order to achieve maximum-security in the project.
Intrusion Detection System shall be based on hardware (panel/s, detectors, panic buttons, interfaces, servers, workstations, printers, etc.) and related software.
All devices of the system shall be addressable to be monitored and controlled.
The optimum solution will provide a totally integrated system in case of having multi-vendor equipment and interfacing between the different components of the system and the other related systems.
