Supervision of building construction, hydraulics structures such as dams, irrigation infrastructures, and water reservoirs

Among others, the site supervisor (site manager) mainly does the following:

  • Define the work in accordance with the drawings and specifications and guide the junior technical teams (junior staff),
  • Solve technical challenges, monitor security issues and regulate quality,

Usually, concretes designated as M10, M15, M20, etc. indicating the concrete resistant in N / mm2 on the 28th day. It also checks on the appropriate concrete mix proportions ((1: 3: 6), (1: 2: 4), etc. ...).
  • Controls on the placement of bar schedules, and,
  • Make decisions regarding changes to the detail drawings provided by the contractor.

A topographical survey is essential in the construction sites to locate and measure features, elevations, and slopes to ensure that the terrain is suitable and convenient for the proposed construction projects. It offers valuable insight into the planning of the prospective utilization of the land for industrial, commercial, residential buildings, schools, or various other structures such as dams, irrigation infrastructure, etc. Along with contours map and boundary survey, topo maps utilized by architects and engineers to make accurate designs based on existing features and attributes.

The benchmarks, staked out by the surveyor will be used as a reference point to guide the construction of the project. At the outset of the construction process, the surveyor layout the paper plan on the terrain in order that the contractors to get started on construction. On top of that, a survey is going to be carried out at the end of the construction to validate that the work completed is in accordance with the specifications set on plans. Therefore, surveying is an important part of any construction project.

Although technological innovations have helped to improve the accuracy of surveying, a skilled surveyor or civil Eng. ensures the reliability of the results. Our staffs are certainly well-qualified and capable of carrying out Total stations survey and delivers computer plotted topographic and contour maps with details and accuracy for any desired project sites.


The role of a hydrologist in a society is significant as it deals with water. Hydrologist examines and interprets hydrological data/information. For instance, assess flood risk, drought and formulate a strategy to deal with them. Investigate the effects of land use such as irrigation and deforestation in a specific area and analyze the repercussions. Besides, assess water budget of a catchment and prepare water use plan.

Monitor data collection and evaluate it employing hydrological and statistical skills. Work with hydrometric to set up, maintain and calibrate equipment such as water levels, rainfall and sediment monitoring devices or structures.

Prepares inundation maps, predict rainfall and runoff and subsequently formulate or recommend strategies how to manage them.

Hydrologist operates in collaboration with other engineers in irrigation, roads, dam, and water reservoir projects and so on.

Our staff members are dynamic and up to date. Able to employ technologies and other advanced as well as widely accepted hydrological models.  Most importantly, work closely with other leading experts and scientists.
