Reliable power and intelligent building controls are the nervous system of every modern facility. Urban Engineering Limited delivers the full electrical utility service chain — from high-voltage substation design and underground cabling to low-voltage distribution, motor control, and building-wide lighting automation — as part of integrated turnkey project delivery or as standalone engineering services.
What sets us apart is our capability to extend beyond conventional electrical contracting into smart building technology: IoT-enabled monitoring, DALI-protocol automated lighting control, Building Management System (BMS) integration, and SCADA for industrial facilities. We deliver systems that do not just power buildings — they make buildings smarter, more energy-efficient, and easier to operate.

Modern buildings in Bangladesh are requiring far more than conventional electrical installation. Facility managers, garment factories, corporate campuses, and government buildings increasingly demand real-time visibility of energy consumption, automated control of lighting and utilities, and the ability to control building systems remotely. Our team delivers these capabilities through proven automation platforms and IoT architecture.

Comprehensive connected load schedules, maximum demand calculations, power factor correction analysis, and harmonic distortion assessments — ensuring transformer and switchgear sizing is accurate and utility tariff structures are optimised.
Short-circuit fault level calculations, protection relay setting coordination studies, and arc flash hazard analysis — ensuring switchgear ratings and protection settings correctly discriminate and safely interrupt fault currents at every level of the distribution system.
Design of earthing systems (TN-S, TN-C-S) to IEC 60364; soil resistivity-based earth electrode sizing; touch and step voltage analysis; and lightning protection system design to IEC 62305 for buildings and critical infrastructure in Bangladesh's high-lightning-incidence environment.
Factory acceptance testing (FAT), site acceptance testing (SAT), insulation resistance testing, earth loop impedance testing, protection relay testing, and full system commissioning with witnessed tests and documented test certificates prior to energisation.

Common questions about electrical utility installations, lighting automation, and smart building systems in Bangladesh.
Obtaining a utility power connection in Bangladesh involves several steps managed through the relevant distribution company — BPDB (outside Dhaka), DPDC (Dhaka south and central), or DESCO (Dhaka north). The typical process requires: application submission with a site plan and load schedule; a load approval letter from the distribution company specifying the maximum permitted demand; design and installation of the customer's substation or service entrance equipment to BPDB/DPDC specifications; inspection and testing of the completed installation by the distribution company's engineers; and metering arrangement and connection agreement. For commercial and industrial customers requiring dedicated 11kV substations, a separate MV connection agreement is needed. Urban Engineering manages this entire process — from load application through substation design, installation, and final utility inspection — on behalf of clients.
Lighting automation replaces simple on/off switching with intelligent, programmable control of luminaires. Key technologies include: occupancy and vacancy sensors that automatically switch lights off in unoccupied areas; daylight sensors (photocells) that dim artificial lighting when sufficient natural light is available; time schedules for after-hours switching; scene control for meeting rooms, lobbies, and production areas; and DALI or DMX protocol networks that give individual control over any luminaire in the building. Combined with LED luminaires (which are 60-70% more efficient than fluorescent alternatives), a well-designed lighting automation system typically reduces lighting energy consumption by 40-60% compared to a conventionally switched fluorescent installation. The payback period in Bangladesh's commercial sector, with current electricity tariffs, is typically 2-4 years.
A Building Management System (BMS) is a computer-based control and monitoring platform that integrates a building's electrical, HVAC, lighting, fire alarm, and access control systems onto a single supervisor. For large buildings — commercial towers, hospitals, hotels, factories — a full BMS is a powerful tool for fault detection, energy management, and maintenance planning. For smaller buildings (below approximately 5,000 sq.m), a full BMS may be unnecessarily complex and costly. However, smaller buildings can still benefit significantly from IoT-based sub-metering (energy monitoring at circuit level), standalone DALI lighting control, and smart thermostat controls — which provide much of the visibility and energy savings of a BMS at a fraction of the cost. Urban Engineering specifies the right level of building controls for each project's size, budget, and operational requirements — not the most complex or the cheapest, but the most appropriate.
Power factor is the ratio of real power (kW) doing useful work to apparent power (kVA) drawn from the supply. A low power factor — common in facilities with large numbers of induction motors (pumps, compressors, air conditioners, lifts) — means the distribution network must carry more current than is strictly necessary for the real power demanded. In Bangladesh, BPDB and DPDC tariff structures for commercial and industrial consumers include a power factor clause: consumers with power factors below a threshold (typically 0.85 to 0.90 lagging) may incur surcharges on their electricity bills, or conversely receive rebates for maintaining high power factors. Beyond tariff penalties, low power factor causes excessive current in cables and transformers — increasing losses and reducing available capacity. Power factor correction is achieved by installing capacitor banks, which supply the reactive power locally rather than drawing it from the grid. Urban Engineering includes power factor analysis as standard in all commercial and industrial electrical designs and sizes correction equipment to bring the installation to unity or the required minimum power factor.
