Geomatics engineers, also known as land surveyors and mappers, design, develop, and operate systems for collecting and analyzing spatial information about the land, the oceans, natural resources, and man made features. The tasks more closely related to civil engineering include the design and layout of public infrastructure and urban subdivisions, as well as mapping and controlling surveys for construction projects. Undergraduate students will utilize a wide range of technologically advanced tools like digital total stations, Global Positioning System (GPS) equipment, and computer-based geographic information systems (GIS).

Concrete is the most widely used construction material. Its quality depends on the quality of its ingredients, the mixture proportioning and its manufacture process. 
The construction materials laboratory enables to determine the properties the different components of the concrete: cementitious materials, fine and coarse aggregates as well as the properties of fresh and hardened concrete according to ASTM and AASHTO standards.
Tests on cementitious materials are performed to avoid any abnormal behavior such as early stiffening, delayed setting, or low strengths in concrete.

Tests of aggregates have two major purposes:
(1) to determine the suitability of the material itself for use in concrete, including tests for abrasion and soundness against saturated freeze-thaw cycles;
(2) to assure uniformity, such as tests for moisture control, relative density (specific gravity), and absorption.
Tests of concrete are made to evaluate the performance of available materials, to establish mixture proportions, and to control concrete quality during construction. These tests include slump, air content, temperature, density (unit weight), and strength.


Covered topics
-Cement testing: 
Soundness, Specific Gravity, Density, Normal consistency, initial and final set, Compressive strength.
-Fine and coarse aggregates testing: 
Specific Gravity, Absorption, Bulk Unit Weight and voids.
-Concrete testing: 
- Tests on fresh concrete: Slump, VEBE, Compacting factor, air content.
- Tests on hardened concrete: Compression test, indirect tensile test.



Available instruments:
-Pan type mixer 300L for preparing concrete mixes



-ADR Touch 2000 Standard compression Machine for computing the compressive and indirect tensile strength of concrete specimens.




 -Slump cone and accessories for determining the slump of fresh concrete.



 -Buoyancy balance for determining the specific gravity of coarse aggregates and concrete specimens.


Beirut Arab University (Tripoli campus) soil mechanics and geotechnical laboratory offers its wide range of experimental facilities for education, research and for collaborations with different companies. One can provide identification and complete characterisation of soil behaviour following specific experimental protocols and standards (ASTM, and AFNOR)

Covered topics:

The soil properties that can be determined in BAU Laboratory are:

  1. Physical properties: water content, Grain size analysis, Atterberg Limits
  2. Hydraulic Properties: soil permeability
  3. Mechanical properties: study of the compressibility and shear resistance of soil

Available Equipments:

Automatic sieve shaker and hydrometer:

In order to determine the particle size distribution curve two types of tests are available:

  1. Sieve analysis—for particle sizes larger than 0.075 mm in diameter,
  2. Hydrometer analysis—for particle sizes smaller than 0.075 mm in diameter.

The Hydraulics Laboratory occupies an area of about 80 square meters in the basement floor of block E. The facility houses the basic equipment used in standard experiments, such as fluid friction in pipes and flow channel, which are normally present in hydraulic laboratories. Laboratory experiments are offered as part of the three basic undergraduate courses: Hydraulics I (CVLE 341), Hydraulics II (CVLE 342), and Thermo-Fluid Laboratory (MCHE 429). Besides laboratory demonstrations, students are divided into groups to perform pre-set standard hydraulic experiments using instruction manuals made available to students.
