Bermuda International Airport
Redevelopment and New Terminal
The L.F. Wade International airport is the world’s gateway to Bermuda, and the redevelopment of its existing Passenger Terminal Building (PTB) was a high priority for the small island country. Because the current terminal is prone to flooding, it is susceptible to damage from major Atlantic storms, which could seriously impact Bermuda’s vital tourism industry.
The PTB redevelopment was undertaken as a P3 project. HH Angus provided mechanical engineering and vertical transportation design for all systems serving the airside and the PTB, working with a local affiliate to deliver contract administration services during construction.
The vertical transportation scope for the project included five new machine-room-less (MRL) traction passenger elevators and four escalators.
Some of the interesting challenges of the project included its profile as an international project on an island; adapting to local authorities having jurisdiction; resistance to hurricanes; flood mitigation; and the island’s water strategy–Bermuda's building code requires that all rainwater be captured and re-used, and the new PTB represents the largest roof area in the country. Also, salt-laden air and accelerated corrosion require the use of non-traditional materials as compared, for example, to similar buildings in Canada.
Among the features of the engineering design, the high water table easily allowed for geo-thermal heat rejection for the cooling plant.

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.
