Before joining UAP, he headed a development company as its Managing Director in Dhaka; worked as a consultant (foundation and structural design) in Dhaka, the Manager Technical Services (Geotechnical Engineering) at Terra-Mar, Inc. in USA and a design engineer at Design Associates Ltd. in Dhaka, Bangladesh.

As a Graduate Research Associate at The University of Oklahoma, USA, Mr. Haque performed extensive experimental and numerical analyses on cracking characteristics of CRCP, (Continuously Reinforced Concrete Pavements). He devised a tensile loading arrangement using a Universal Testing Machine to simulate inherent shrinkage cracks in CRC pavements and also developed a two-dimensional model of the CRC slabs using FLAC, a commercially available software package based on the finite difference method.

Mr. Haque had been involved in many industrial, commercial, residential, private housing and public projects in the city of Houston, Beaumont and Austin in Texas, USA. Scope of works under these projects included extensive field and laboratory investigation and geotechnical analyses and engineering recommendations for the design and construction of under reamed drilled pier foundations, pile foundations for single and multi-span bridges, retaining walls, communication towers, pavement thickness design and subgrade preparation, underground utility lines and lift stations. He performed extensive slope stability analyses to evaluate the stability of existing and proposed slopes and provided recommendations regarding geometry, preparation and drainage to construct/maintain safe and stable slopes for numerous landfills, lakes, retention ponds and bayous in Texas.

He has been involved in the geotechnical investigation, foundation and structural design as well as pile load tests of numerous multi-storied residential and commercial projects, shopping complexes, effluent treatment plants in Dhaka Division.

At UAP, Mr. Haque currently teaches courses like Engineering Mechanics, Soil Mechanics, Engineering Geology and Geomorphology, Foundation Engineering and Soil Mechanics Lab. His research includes calculation of bearing capacity of foundations, assessment of geotechnical properties of Dhaka subsoil.
