Public Prosecution Office Building

Project Description

Over a land area of 18,053 m2, the Omani Public Prosecution Authority office building was built in El- Erfan City. With a built-up area of 14,772 m2, the building consists of a ground floor and five floors. To achieve functional independence among users, the building has five separate entrances: one for the Attorney General and VIPs with a panoramic elevator; one for the conference hall; one for visitors; one for employees connected directly to the parking area, in addition to a service entrance.

The building floors are designed as open-space areas to accommodate the requirements of the Omani Public Prosecution Authority for various departments with associated services comprising:

  • Office for Attorney General
  • Administrative offices
  • A conference hall with capacity of 200 persons
  • A reception hall for VIPs
  • Waiting areas
  • Three employee elevators
  • Other facilities including male/ female restrooms and prayer rooms, kitchen, exit stairs and service elevators.

The conceptual design of the castle-themed building associated Omani architectural heritage, with modern design elements and functionality.

ECG is well-known for its dedication to environmental sustainability which was adopted by our client through incorporating the latest infrared technology applications. This technology aims to analyze electricity and water consumption, consequently reducing its carbon footprint and contributing to the environment.

The environmental elements, topography of the site and existing natural slopes, provided us with beneficial factors to utilize; through creating an additional floor and decreasing excavation and backfilling works, resulting in reducing construction duration and cost.

The building’s courtyard was covered by “skylight” to provide internal illumination, to minimize energy consumption and maintain internal cooling.
