Civil Engineering

NHL offers a wide range of consultancy and other services in the civil engineering discipline.

Bridge Foundation Design/ Consultancy, where our experience lies in designing work bridges, cofferdams and retaining walls (design against slide, uplift/overturning moment, lateral earth pressure…)

Roads and Highways Design/Consultancy

Quality control of  road surfacing material is usually called ‘asphalt concrete’; we offer our service in pavement engineering – a branch of civil engineering that uses engineering techniques to design and maintain flexible (asphalt) and rigid (concrete) pavements. This work includes streets and highways and involves knowledge of soils, hydraulics, and material properties; pavement engineering uses new construction as well as rehabilitation and maintenance of existing pavements. NHL uses engineering judgment to make maintenance repairs with the highest long-term benefit and lowest cost. Design of permeable paving – also called pervious paving or porous pavement – is the term used to describe paving methods for roads, parking lots and walkways that allow the movement of water and air through the paving material.

Slope Rehabilitation Design/Consultancy

The field of slope stability encompasses using software analysis of static and dynamic stability of slopes of earth and rock-fill dams, slopes of other types of embankments, excavated slopes and natural slopes in soil and soft rock.

PROJECT MANAGEMENT

NHL offers effective project management to achieve all of our project goals and objectives while adhering to classic project constraints—usually scope, quality, time and budget. We optimize the allocation and integration of inputs necessary to meet pre-defined objectives.

Quality Control for Foundations/roads and other Design details

Ensuring products or services are designed and produced to meet or exceed customer requirements, we provide inspectors with control tools such as sampling and control charts making inspection organization more efficient.
