The firm has its own geo-technical section which carries out field and laboratory investigation to establish foundation requirements and materials for pavements, buildings, roads and other major structures.
The firm has been involved in many Airports, Roads, Bridges and Water Transportation studies, either as self contained projects or in support of the wider engineering services provided by the Firm.

Air Transportation
In the area of air transportation, the firm has been involved among others in planning, economic and engineering feasibility studies, preliminary and final engineering designs of a number of airport projects.

Details of some selected projects are listed below viz.

           Planning, survey and engineering design of Obudu Airstrip:

           Final engineering design for the Terminal and Buildings for the Kano International Airport;

           Planning, economic and engineering feasibility studies for the 2nd phase Airports Development in Nigeria involving 8 airports (in association with SOFREAVIA, Paris);

           Design review and supervision of construction of aeronautical area and the access road at the Akure Airport.

           Planning and final engineering of Minna Airport complete with terminal facilities;

           Survey, sub-soil investigation, planning and preliminary engineering for earthworks and pavement for Owerri Airport (in association with SOFREAVIA, Paris);

           Planning, survey and final engineering for earthworks and pavement including access road for the Makurdi Airport;

           Site selection studies, planning, survey and final engineering for the earthworks and pavement including access road for the Onitsha Airport.

Roads and Bridges Roads

The firm has been involved in the study, investigation, survey, planning, engineering designs and construction supervision of well over 40 different road projects all over the country. The scope and size of these projects are varied, ranging from Federal Highways to Estate Roads and in lengths from 20km to 200km.
Details of some selected projects are listed below:

    Planning, investigation and   preliminary design of the Abakaliki-Ikom-Cameroun Boarder highway including the design of 20 bridges (in association with Garnet Fleming Corrdry & Carpenters. U.S.A.); Preliminary and final engineering  design and construction supervision of road networks for 22 Federal Government Colleges.     Feasibility studies for the Seme Pogi - Cotonou Road in the Republic of Benin for the Federal Ministry of Works.     Location survey and final engineering design for the 230km Beni Sheik-Damboa-Uba Road including bridges.

Bridges The firm has undertaken the design and construction supervision of many bridges either as separate projects or in combination with a road project. Notable projects that the firm has undertaken in this field include:

      Final engineering design and supervision of construction of the 8km section of the third axial road (third mainland bridge) into Lagos (Maroko to Oworonshoki) of which 5km is elevated above the Lagos Lagoon including the five bridges of the Oworonshoki Interchange. (In association with NIDAN consult);

      Final engineering design of the 3rd road bridge over the River Kaduna. It comprises of 2 bridges each of 300m long dual carriageway (in association with NIDAN consult);

      Final engineering design of the 225m long pre-stressed concrete bridge over the Cross River on the Udi-Ugep road;

      Planning, final engineering design and supervision of construction of the 150m long Imo River Bridge on Port-Harcourt to Aba road. Design was based on Cantilever and Drop-in concept.

Water Transportation

Water transportation is the most economic mode of transport in Nigeria where the cost of petroleum fuel is relatively high. Some parts of Nigeria are fairly well endowed with rivers, creeks and streams which have potential for the development of water transportation.

Some of the projects that the firm has been commissioned for include the following projects:

• The Development of the River Niger for Navigation, carried out in association with NEDECO and Royal Bos Kalis Westminister Group for the Federal Ministry of Transport. The project involved a comprehensive study of the River Niger from Lokoja to Warri for Navigation Development. It was considered that such a river navigation development should take into account the provision for other purposes of river improvement. e.g. flood control, domestic and industrial water supply, irrigation, fishing and agricultural use, electricity generation etc.;
  
• Studies, field investigation and design of works involving flood control and channel regulation to improve navigation in the Stubb and Widenham Creeks for the Inland Waterways Division, Federal Ministry of Transport;

• The development of the Oguta Port access navigation channel. Relevant aspects of the project involved studies and design of flood protection measures at the River Niger entrance bay to the Navigation Channel;

•    The development of the Ajaokuta Port involving the studies and design for flood protection at the site of the commercial port on the River Niger at Ajaokuta. The influence of the port on the regime of the river and the effects on the near-by bridge was studied and integrated into the design.
