Bangalore (Kempegowda)

International Airport

The Bangalore (Kempegowda) International Airport airport expansion will increase the airport’s capacity to at least 65 million passengers per annum. Phase 1A of the new Terminal currently includes an estimated 46 elevators, 29 escalators, and 17 moving walks.

In addition to the new Terminal, a multi-level car park is being constructed to accommodate an estimated 2438 passenger vehicles after Phase 2. In addition to the vehicle stalls, there is capacity for an estimated 450 taxi’s after Phase 2. A Metro connection to the Terminal is also planned following Phase 2 expansion, for which elevating provisions are currently being made.

HH Angus’ client is Skidmore, Owings & Merrill LLP (SOM) from New York, with whom we worked previously on a joint-venture architectural team with Adamson Associates and Moshe Safdie on Terminal 1 at Toronto Pearson International Airport.

Bonaire, 14 MWe Power Station

The island of Bonaire (formerly the Netherlands Antilles), has been a special municipality of the Netherlands since 2010. It lies in the Leeward Antilles chain of Caribbean islands, with an area of 288 square kilometers (111 sq.mi.)

With the commissioning of its sophisticated new sustainable wind-diesel hybrid power plant, Bonaire became the first Caribbean island capable of 100% renewable energy. This project’s aim was to transform today’s largely fossil fuel-based energy supply infrastructure in Bonaire into one based on the application of 100% sustainable energy sources within five years (bio diesel extracted from algae).

The Bonaire project featured a 14 MWe turnkey power station with site work, roads and electrical connections. HH Angus was responsible for all mechanical, electrical, civil structural engineering, including various piping systems (heavy fuel oil, light fuel oil, lubricating oil, compressed air, etc), high and low voltage distribution, and PLC control systems. All mechanical detailing was completed with 3D CAD software, with related materials captured in Excel for the bill of material procurement.

Our design scope covered a capacity increase to 20 MW (designed for future use) and was based initially on Heavy Fuel Oil (HFO) as the principal fuel, and light fuel oil (LFO) as an alternative. The plant was designed with the capability to be converted to operate on biofuel in future. Also included in the project was an extensive tank farm with storage of HFO, LFO and lubricating oil.

The plant consists of 5 X2.85 MWe MAN Diesel generating sets at 11kV, and was designed as a base load plant with parallel displacement production from a windfarm generating system. Each genset is selectable to dual busbar systems that each step up to 30kV for island distribution.

This is the only power plant on the island. The diesels supply voltage regulation, as well as VARs and power production to supplement the island’s needs when wind production has been harvested to maximum benefit.

Special care had to be taken to integrate the control systems of the wind turbines and the diesel engines, as the grid performance has to be maintained through fluctuations of the wind resource. The diesel engines have to respond to the changes in output from the wind turbines in order to maintain electrical grid balance.

Ariguanabo Cuba, ~23 MWe Power Generation Plant

In 2006, the government of Cuba began an ambitious $2 billion program to modernize its decaying Soviet-era energy infrastructure.

For this ~23 MWe turnkey power station in the town of Ariguanabo, approximately thirty miles from Havana, HH Angus was engaged to provide all mechanical and electrical detailed design, including various piping systems (heavy fuel oil, light fuel oil, lubricating oil, compressed air, steam tracing, etc.), as well as high and low voltage distribution.

The power plant consists of twenty ~1.15 MWe MAN diesel generating sets and was designed as a continuously operating plant.

Generation is at 13.8kV onto a double-ended station (10 generators/bus), stepping up to 34.5kV for distribution across the entire island of Cuba. The plant was designed to operate as a base load plant. The site included extensive tank farm storage of heavy fuel oil, light fuel oil and lubricating oil. Steam tracing was provided on HFO systems. The main fuel is heavy fuel oil, with light oil as the backup.

Bermuda Magistrate’s Courthouse & Hamilton Police Station

This 128,000 ft2 facility for the island nation of Bermuda includes five courtrooms, police facilities, an underground parking garage, detention cells suitable for overnight and weekend accommodations, a sally port, staff change and locker facilities, offices for court and police staff, and interview facilities.

HH Angus’ scope included mechanical and electrical engineering, IMIT, and AV design. The building is equipped with air conditioning and water retention tanks and is fully sprinklered. Water tanks collect rain water for both potable and fire protection requirements. Cooling equipment consists of air-cooled condensers and indoor compressors to minimize the exposure of equipment to the corrosive effects of salt-laden sea air.

The electrical scope included a high voltage power service, emergency power generator and corresponding dual distribution systems. Selected lighting, equipment and duplex receptacles were connected to emergency power.

The fire alarm system has dual annunciators. Smoke detectors were provided for each individual cell and located to avoid potential vandalism. Detectors were individually addressable in order to rapidly locate individual detectors triggering an alarm.

Fully-integrated closed circuit television, card access and door security monitoring systems were designed. The structured cabling system was a single mixed-media network to all information traffic - voice, video and data.

The latest audio visual technology was installed in the courtrooms: active sound reinforcement system, video system for the presentation of evidence, paging system for the judges, videoconferencing system for remote testimony and deposition, and digital recording system for proceedings recording. In addition there are dedicated elevators for prisoner transfer and additional retention cells adjacent to courtrooms.

Barclays Bank Headquarters & Computer Centre

Barclays Bank was named as one of “the 30 most significant buildings constructed in the past 30 years” in 2008 by the respected ‘Building Services Journal’.

The Barclays Bank building was singled out for its robust design, which featured a high standard of sustainability and energy efficiency, rare attributes for a high technology building. It also earned the UK's "Breeam Excellent" rating, comparable to LEED^® Gold.

The tower consists of a main operations facility, data centre and trading floor with 32 floors above grade, 1,000,000+ ft2 of computer centre, trading floor and high technology office space. HH Angus provided an overall electrical and mechanical design that ensures there are no single points of failure.

Mechanical services were designed to achieve high quality practical solutions for the high cooling loads, while ensuring flexibility for subtenants and office churn. The systems boast dual risers and split plant for the majority of services in order to provide continuity of service for maintenance or in the event of failure.

Electrically, the building has an extremely resilient service provision with dual incoming electrical supplies, 8 MVA of UPS power and 12 MVA of generator power available. The design included dual 11 kV service entrance, a dual 11kV APS systems (12MW), a 2(N+1) UPS topology (8x800kW). All electrical services were provided in a dual riser and split plant format, providing continuation of service under failure or maintenance.
