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,
Measures and assesses quantities jointly with the quantity surveyor (quantity expert),
It controls materials purchased or ordered if it complies with the designated requirements,
Validates and confirms that the drawings of the finished works supplied by the contractors,
Verifies that the contractor performs tests / evaluations on the materials before using them, for example, resistance tests on concrete, water tanks, water pipes, sewers and other materials of Construction. 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.
Our office can help you provide qualified supervisors and help you achieve your goals
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 lay out the paper plan on the terrain in order that the contractors 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.
HYDROLOGICAL STUDIES AND DESIGN
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.
Our staff contains specialists in engineering hydrology, civil engineering, and irrigation domains; as a result, we predominantly offer professional services in these areas. Additionally, we often work with outstanding experts who are leaders in their respective fields as well.
Our staff has considerable practical experiences in Eritrea, Ethiopia, South Africa, and Switzerland in the areas of design hydrology and catchment studies, Hydraulics, irrigation infrastructures, 3D building Modeling, dam, and supervision of building construction.
The vision is to add values to communities and putting the proficiency attained in more than 20 years of experience into practice. Particularly we presume that we are able to play a part sufficiently in the sectors such as hydrology and hydraulics, Modeling, irrigation, dams, river training works as well as housing construction.
We are smaller in size aspiring to expand in the near future and provide services in the Geneva area in collaboration with partners and associates.
We would like to work jointly in the areas where we are able to add considerably to bring in a difference in communities or simply be of importance. Our objective is always to improve our service quality and our engineering endeavors by teaming up with local or regional agencies.
The use of hydrological and mathematical models proficiently, employing advanced engineering instruments in our tasks, having access to technologically advanced support systems, and access to advanced lab tools, the capability to implement up-to-date engineering software programs render us a competitive edge in our profession.
With an urge to serving our clients best, the “hydro engineers” work in association with networks of regional experts who are able to bring in their competencies whenever collaboration needed.
We are a dedicated team striving to convey progress into our community, we foresee needs and deliver every pledge we made.
