The Rural Improvement Program was a series of projects aimed at restoring Cambodia's rural infrastructure. The program was implemented by the Ministry of Rural Development of the Kingdom of Cambodia from 2005 to 2018 with the support of the German Government.

Several JEB employees have participated in the projects, performing surveys, designing and supervising the construction of rural roads, water crossing structures, and markets.

At the request of Total Energies Renewables Cambodia, JEB performed a structural assessment and provided the complete structural analysis of the roof and load bearing members of a garment factory located in Phnom Penh. The project objective was to determine if the factory structure had the capacity to support the additional load of roof-mounted solar panels.

Following the fieldwork and in-office analysis, it was determined that the factory required structural strengthening works in order to support the added load of roof-mounted solar panels. Structural strengthening design using steel structural tension rods along with a cost estimate were developed and accepted. PESTECH Cambodia then hired JEB to implement the structural reinforcement and strengthening.

752kW solar panels are now being installed on the roof of the factory. Once complete, the factory will begin reducing its carbon footprint utilizing renewable energy!

Grundfos, the contractor for the Prek Po Pump Station (MOWRAM), requested JEB’s mechanical and electrical consulting services for the technical aspects of the project: validation, testing, commissioning and construction management.

Between 2010 and 2013, several JEB employees participated in the Cambodian Railway Rehabilitation Project: 163 kilometers on the southern line from Phnom Penh to Sihanoukville, 48 kilometers on the northern line from Sisophon to Poipet, and 32 kilometers from Phnom Penh to Bat Deng.

The southern line railway is a 1-meter narrow gauge, single-track line rehabilitated with concrete sleepers. The northern line was rehabilitated at a low cost by keeping the existing steel sleepers.

Jeremy lead six topographic surveyor teams and managed the project through all design, earthworks, structural works, track installation, tamping, and as-built phases.

A private property along the Mekong river in Prek Dambang was losing approximately 50 meters of land due to natural erosion. Jeb managed the entire project scope (surveys, analysis, design, and construction) to rehabilitate the riverbank through the use of geotextiles and earthworks such as toe protection, slope filling and protection, and galvanized gabions (14,122 m3 of stone, 6,403 m3 of geotextile, and 1,120 m3 of gabion). These protective measures minimized land losses and increased the owner’s property value.

In 2017, the Ministry of Infrastructure Development of the Solomon Islands wanted to prepare for road and bridge construction as well as wharf development in six different provinces.

JEB teams performed topographic and bathymetric surveys as well as hydrologic studies. These studies are crucial for the long-term sustainability of island infrastructure which is often threatened by cyclones and other climatic problems.

We conducted two aerial surveys, LiDAR and photogrammetric, over the Sihanouk International Airport and surrounding area to study the airport’s flood protection and drainage capabilities. The survey area was approximately 800 ha and required four flight days to complete.

Cambodia's largest garment factory complex, employing over 15,000 people, had a habitual/recurring flooding issue every year.

In 2019, JEB performed a topographic survey to build storm and sanitation models. We identified critical bottlenecks in the drainage system after analyzing the models and using our local hydrological knowledge.

The client received two different solutions to solve the flooding issues: a quick and affordable short-term repair solution and a long-term storm drainage concept and design taking into account any future complex expansions.

Since 2018, JEB has been consistently upgrading the topographic knowledge of the Sihanoukville airside area. Cambodia Airports requested a high-accuracy topographic survey of the airside, runway, and apron. The site is made of mangrove and marsh making the surveys particularly challenging. A reaffirmation of the airport boundaries was also performed to protect the site from land grabbing.

In 2019, JEB surveys & engineering provided an architectural and a non-destructive structural survey work for Phnom Penh train station. We provided drawings with the exact building geometry and all the necessary documentation to conduct an up-to-date structural analysis.
It able the Architect to prepare the renovation and refurbishment to commercial use to one of the oldest and most iconic building of Phnom Penh.

Properties along the Mekong River to the north of Phnom Penh are subject to substantial erosion and slope degradation. Several areas are losing up to ten meters of land every year.

JEB has provided bathymetric surveys and civil engineering design services for several properties. We have the capacity to produce protective and rehabilitative measures that minimize the effects of erosion.

To prepare for the 800-meter extension of the Sihanoukville International Airport runway in 2018, JEB carried out geotechnical investigations. The investigations, performed in the southwestern area of the site, covered 1500 meters of ground soil with over 75 tested locations (by CPTu or borehole drilling and sampling).

J Trust Royal Bank approached JEB to obtain a detailed structural assessment of one of their bank branches in Phnom Penh, Cambodia. To do so, we conducted a visual examination of the structure, bored concrete slabs in several locations, lab tested the extracted cores, and installed crackometers for periodic monitoring. A detailed structural drawing and analysis were provided.

In 2019, JEB's survey, engineering, and laboratory teams participated in the renovation of the LRU Apron Project at Phnom Penh International Airport. The LRU Apron consists of 12 parking areas for Class C airplanes like the A320 or the B737.

The teams conducted all necessary surveys and investigations to prepare the designs and develop the shop-drawings. Then they guided the paving team to lay 15,300 tonnes of asphalt to the correct geometry and proper quality. The teams were also responsible for the marking and lighting stake out, the arrangements for connecting to the runway, and the setting of drainage.

The Cambodian Ministry of Agriculture, Forestry, and Fisheries was planning the design of a new governmental building in 2019.

JEB performed a topographic survey and soil investigation at the request of the project's architect, The Room Design Studio.

The project, funded by the Food & Agriculture Organization (FAO), was successfully completed under the scrutiny of the United Nations Development Programme (UNDP).

JEB performed topographic, bathymetric, and aerial surveys to prepare a port feasibility study and concept design. The survey area consisted of an area of approximately 11 hectares partially on land and partially under water. From the survey data and analysis, detailed 2D and 3D drawings of the location were produced enabling the design of the clients personal port.

In 2019, JEB provided civil engineering design services for a residential and industrial park. This includes roads, earthworks, drainage systems, electricity and water supply, and wastewater management. As these projects are still under development, the Clients have requested to remain anonymous.

In 2020, contractors on a 220-hectare plantation in the south of Cambodia needed soil and volume information to organize their work plans and make adjustments to the final land levels. A photogrammetric survey was performed to estimate the volume of soil needed while keeping costs down.

JEB conducted a structural assessment and analysis at the Sportex factory to determine if the structure had the capacity to support the load of solar panels. A strengthening design and cost estimate were created following the geometrical survey of roof frames and complete structural analysis of the roof and load bearing members.

JEB performed a large topographic survey with a combination of traditional topographic surveying methods and drone photogrammetry. The work included the survey of the property boundary, a detailed survey of all areas within the boundary including several buildings, manmade reservoirs, and multiple natural features, and an aerial survey of the area to produce orthophotography of the site.

Grundfos reached out to JEB for technical support on a warranty case concerning Takeo's local water supplier. Our M&E specialist, Robert-Jan, conducted an emergency investigation and reported back with solutions. JEB was hired to resolve the technical issues and to conduct testing to ensure the system was operational.

A private client tasked JEB with designing concepts for a private port to be located in Kampot, Cambodia. The port requirements were to store two large vessels under cover, out-of-water, and with the ability to be lifted, secured, and transported to another location. Before designing the port, JEB first conducted a topographic and bathymetric survey. Following the analysis, JEB designed and presented seven different concepts. The chosen design demonstrated the construction of a boathouse equipped with a gantry crane, boat ramp, and boat lifts, the boathouse being accessible via a concrete channel into the river and a private jetty for short term storage.

A private company approached Jeb to determine the amount of land to be flooded due to the construction of a nearby dam. An aerial lidar survey was performed as the land area was quite large. The survey required seven days to complete. The final result was the production of several detailed maps depicting the quantity of land at risk of flooding and the topography of the site.

JEB provides topographic survey and soil investigation services for private owners and land developers. Topographic surveys are used to determine accurate project boundaries as well as drainage and utility connections. Soil investigations are used to determine foundation designs. The team is especially careful to provide correct and detailed information as per the client's requirements.

2015, the Consultant models the drainage for the 4.4ha MINIBEA Factory (Phase III) on behalf of the Contractor SATO-KOGYO. The result were later implemented into the concept design phase to be included in the factory design by the Contractor.

In 2021, JEB was commandeered by BECIS Industrial Solution to provide the civil engineering design for a boiler to provide a sustainable source of energy to the brewery. JEB was responsible of the entire civil engineering design encompassing all surveys, topographic geotechnic and of the existing facilities, as well as the structural and MEP design in coordination with the boiler supplier VYNCKE, and the industrial architecture.

In 2019, JEB conducted a comprehensive feasibility study for a phased, mixed-use development spanning 50 hectares in Phnom Penh. The envisioned project will integrate commercial and office spaces, residential areas, and light industrial zones, with a network of roads seamlessly connected to the existing city infrastructure. The development is planned in two phases: the first phase, covering 6 hectares, is scheduled to commence next year, while the second, more extensive 50-hectare phase, is targeted for development by 2025.

The Client has requested a full feasibility proposal encompassing:

• Review and assessment of the existing topographic survey for the entire site.
• Hydrogeological and environmental studies, including detailed flood risk analysis, identification of the highest flood levels, and evaluation of seismic, wind, and other potential hazards.
• Conceptual drainage design for both development phases.
• Site reconnaissance and due diligence for essential utilities, including potable water, electricity, and internet, with recommendations for necessary extensions and guidance on permitting processes with local authorities.
• Shallow soil investigations to assess subgrade conditions for road and drainage design, accompanied by road design recommendations in accordance with Cambodian standards.

The Client has expressed particular concern regarding flooding, noting the increasing urban development in Phnom Penh, where many drainage outlets, rivers, and canals are inadequately maintained or encroached by informal settlements. This study aims to provide a robust, resilient, and forward-looking strategy to mitigate such risks while supporting sustainable urban growth.

This survey project took place in Kep National Park and was conducted in collaboration with the Ministry of Environment to determine the locations of trees based on specific criteria. Two remote sensing methods were employed for the survey of the densely vegetated hill, LiDAR and Photogrammetry.

Following the survey and data processing phases, we analyzed the spatial data to select trees based on the criteria and extracted other information such as tree canopy size and tree heights. The resulting topographic maps contained plan views, section views, contour lines, and tree and canopy color maps.

We participated in the newest high-rise building development in Phnom Penh, The Sunwah Pearl.

A dilapidation survey of the surrounding area took place, ensuring all parties have documentation concerning the existing state of buildings. This type of survey provides all stakeholders with proof to minimize liability during construction in urban areas which often causes strong vibrations.

Following the dilapidation survey, we launched a geotechnical investigation using boreholes and laboratory testing. In addition, we provided the Contractor with survey secondment until the completion of the foundation phase of the project. One of our survey teams was embedded within the Contractor's team for six months to perform various checks and to set out locations for piling works.

In 2018, JEB conducted a comprehensive feasibility study for a multi-phase mixed-use development project covering 50 hectares in Phnom Penh, Cambodia. The proposed project will integrate commercial and office spaces, residential areas, and light industrial zones, with a road network connected to existing urban infrastructure. The development is planned in two phases: the first phase, covering 6 hectares, is expected to begin next year, while the second, larger phase, covering 50 hectares, is scheduled to be developed by 2025.

The client requested a full feasibility proposal including:

• Review and assessment of the existing topographic survey for the entire site.

• Identification of various utility networks, including potable water, electricity, and internet, with recommendations for necessary extensions and guidance on permitting procedures with local authorities.
• Soil studies to assess the conditions of surface soil layers for road and drainage design, accompanied by recommendations for road design in accordance with Cambodian standards.

The client expressed particular concern about flooding, highlighting the rapid urban development in Phnom Penh, where many drainage outlets, rivers, and canals are inadequate.

JEB has engaged to develop a comprehensive proposal for the concept design of drainage system improvements, the existing drainage network, primarily based on a pond and pumping system, was documented only in hard copy, limiting its accessibility and usability for analysis. Recognizing the increasing flood risk, the Client emphasized the need for a robust and future-proof solution, particularly given the rapid urban development in Phnom Penh. The city’s drainage outlets, rivers, and channels are increasingly affected by inadequate maintenance and encroachment by informal settlements, heightening flood vulnerability. JEB Surveys & Engineering proposed an integrated approach, combining detailed system assessment, hydraulic analysis, and sustainable design solutions to enhance flood resilience and ensure long-term functionality of the drainage infrastructure.

In 2021, JEB was commissioned by the Client to provide comprehensive technical support for the feasibility study of a 176-hectare solar farm in Trapeang Ruessei Commune, Kampong Svay District, Kampong Thom Province. Our expert team conducted a full suite of field investigations, including detailed topographic surveys, flood risk assessments, geotechnical soil studies, and resistivity surveys, delivering accurate and actionable data to inform project planning and design.

The fieldwork was executed with precision and efficiency to ensuring timely delivery without compromising quality. By integrating advanced surveying techniques with thorough environmental and geotechnical analysis, JEB Surveys & Engineering provided the Client with a solid foundation to advance their renewable energy project with confidence. This project exemplifies our commitment to combining technical excellence with sustainable development, supporting initiatives that drive Cambodia toward a cleaner, greener future.

In 2021, JEB was commissioned to conduct a comprehensive topographic survey of a 22.5-hectare site in Tonle Bati, Cambodia, supporting the Client’s development planning and land management objectives. Our team employed state-of-the-art photogrammetric survey techniques to deliver highly accurate and detailed site data. Key tasks included establishing and verifying land boundaries, producing a high-resolution ortho-mosaic of the entire site, and generating a precise Digital Terrain Model (DTM) to capture all elevation variations.

The survey provided critical insights into the site’s topography, enabling informed decision-making for future development projects. Fieldwork was efficiently completed over a span of just three days (March 22–24, 2021), combining speed with meticulous accuracy. By integrating cutting-edge technology with expert field surveying, JEB Surveys & Engineering ensured the delivery of reliable, actionable data tailored to the Client’s specific project requirements.

We surveyed and mapped a five-kilometer stretch of the Mekong River in Phnom Penh. We used our LiDAR to survey the riverbanks of Phnom Penh and Koh Dach. Our Echo Sounder was used to survey the riverbed. In addition, we used our electromagnetic meter to determine the current velocity in different areas and at different depths.

The topographic and hydrographic surveys produced more than 4.5 million survey points with X, Y, and Z coordinates. This point cloud was cleaned using manual processes and machine learning algorithms to generate terrain models. The models were then combined to create plan and section views of the Mekong, from bank to bank.

This was a very unique hydrographic survey project. Due to the size and shape of the area to be surveyed, we could not use our usual boat, DGPS, and echo sounder setup. We designed, built, and tested a custom device to enable the survey. The project was a success resulting in thousands of survey points and a map that proved to be valuable for the Client.

On behalf of the Phnom Penh Water Supply Authorities' request, we conducted an initial soil investigation in 2022, involving 5 boreholes, 5 CPTus, and laboratory testing in the Phnom Penh Special Economic Zone.

In 2023, the project extended to include 4 additional boreholes and 4 CPTus, aiming to determine soil and rock stratigraphy to a depth of 40m, assess physical and mechanical properties, and analyze groundwater chemical properties. This data informs the foundation design for the PPWSA project to ensure it’s structural integrity.

This structural assessment involved evaluating three buildings at the Lycée Français René Descartes School. We tested the foundation, structural members, slab and concrete quality using the Schmidt Hammer and Ultrasonic Pulse Velocity (UPV) tests. While the analysis was conducted with the ETABS Building Analysis and Design software. This enabled us to thoroughly examine the structural integrity of the existing buildings and offer practical recommendations for the strengthening of the existing structures, adding extra floors and choosing suitable materials.

At the request of VINCI Construction Grand Project, we conducted two As-Built bathymetric surveys at the water treatment plant intake in Bakheng. These surveys were carried out in conjunction with the riverbank rehabilitation project under construction.

The surveys were conducted one month apart, offering the client a comprehensive cross-sectional perspective of the rehabilitation work and the changes in the riverbed around the intake.

We performed a structural assessment on two SHEICO factory buildings to assess their ability to support the installation of photovoltaic panels. We conducted an on-site investigation to verify the dimensions of the structural members and confirmed the steel hardness using a hardness tester. The data collected was used to create building models for further analysis.

Following our assessment, we provided the client with our expert evaluation, which included recommendations for suitable locations and methods for solar panel installation on the roofs, and outlined potential strengthening solutions where they were deemed necessary.

In this project for Immersive Angkor, we conducted a complete feasibility study for the land development, starting with the topographic survey of the entire land, the verification of its boundaries. Next an assessment on flood risk was done and we provided the remedial solution to prevent it.

Afterwards, a soil investigation involving two Cone Penetration Tests (CPTus), reaching a depth of 22 meters. The on-site test results informed a comprehensive report detailing the soil's stratigraphy. The data gathered enabled us to offer our client with foundation design recommendations and soil improvement strategies to ensure a customized and well-informed strategy for the project's specific foundation requirements.

Combining the flood risk assessment and the geotechnical investigation result, it was decided to backfill the land of 2m by technical backfill and to improve the soil below to able the construction of large span single storey building and parking. JEB supervises the construction of the backfill and assure that the compaction was done according to the specification.

This structural assessment was performed to determine if extra classrooms can be built on the third floor terrace of the Institute Francias du Cambodge school.

To perform this analysis, we carried out a survey of the second floor, including testing structural elements with the Schmidt Hammer and Ultrasonic Pulse Velocity (UPV) tests, as well as visually inspecting the steel components.

After modeling the building using the data we collected on-site, we provided the client with practical recommendations regarding building materials and space usage to ensure safety.

Our project in Yamoussokro, Côte d'Ivoire, involved providing technical documentation for the civil works construction of the Yamoussokro airfield. We delivered design plans for various components, including the runway, runway end safety area (RESA), taxiway, taxilane, and parking.

These plans included contour lines with 0.1/0.5m intervals, slope analysis, earthworks plans, cut and fill calculations, as well as profile and section drawings, offering our client a comprehensive and practical framework for the construction process.

At the request of the project Consultants, JEB conducted a topographic survey on the 6-hectare plot of land and a tidal survey near the site, located in Hawaii Beach at Sihanoukville.

The environmental study on tides and sea levels contains recent observations and projected tidal levels during the survey period as well as data collected over the past 15 years for coastal management, cross-referenced with the Sihanoukville port authorities and surveys conducted at Ream Airport. This data informed our estimations of pressure and surge storms, wave dynamics, currents, climate change implications, and evaluations of extreme events.

We then provided jetty and coastal platform level recommendations to the client.

In addition , JEB completed CPTu testing on 18 locations at this private property. The tests were completed up to a finishing depth of 9.8 meters and able to obtain information on the physical and mechanical properties of the subsoil layers and stratigraphy. A comprehensive bearing capacity report was delivered to the designer in order to plan shallow foundations for their future projects.

The Client, ENSEAS Cambodia, tasked us to assess the structural design proposed for a 19.2 x 4.8 meter billboard installation at Phnom Penh International Airport.

To conduct this assessment, we conducted a survey involving the inspection of columns and horizontal bracing, as well as measurements of span, length, and spacing of structural elements. We also tested the footings for concrete strength using a sclerometer.

Using the data collected during the site visit, we created a model of the billboard and provided recommendations for strengthening structural members, improving footing connections, and enhancing bracings to ensure safety.

In this project, we focused on developing a riverbank protection design for a 35-meter stretch along the Mekong River. Our initial step involved conducting a topographic and bathymetric survey of the site to assess the current condition of the riverbank.

After completing the survey, we used the gathered information to deliver a comprehensive riverbank reinforcement design to our clients. These drawings included detailed designs and cross-sections for the upcoming construction phase of the project.

On behalf of Nihon Suido Consultants, JEB conducted an extensive survey encompassing topographic, bathymetric, and soil investigations of the Ta Khmao Bridge. This survey aimed to collect data for the execution of the Nirodh Water Supply Expansion Project, financially supported by the Japan International Cooperation Agency (JICA).

The soil investigation involved employing two CPTus, one on each side of the bridge to a 40 meter depth. The topographical assessments spanned from the roundabouts on both sides of the bridge, while the bathymetric survey was performed on the area beneath the structure.

We then provided the client with a Digital Elevation Model (DEM) with the data gathered on site for the design phase of the Ta Khmao water treatment plant to facilitate efficient project planning.

This topography project was conducted at the Bakheng Water Treatment plant. The survey stretched from the channel of the bridge No.7 on National Road No.6 to the riverbank located in at Bakheng, Phnom Penh.

A Digital Elevation Model (DEM) with 0.2 meter contour line interval range and 16 cross sectional drawings were prepared and provided to the client.

In this project, we conducted a topographic and bathymetric survey of the Prek Ho Bridge and the Prek Thnaot River along National Road 2. For the topographic survey, we employed DGPS RTK Survey mode and Total station Sokkia Set IM-101. Simultaneously, the bathymetric survey utilized an echo sounder single beam and DGPS Spectra.

We provided our client with a Digital Elevation Model (DEM) with 0.5 interval contour lines detailing the bridge and 60 meter stretch of road on both sides of the bridge.

This project at the National Bank of Cambodia Kampot Branch, involved a comprehensive land and boundary survey, coupled with an architectural survey of the building.

We provided our client with a Digital Elevation Model (DEM), a survey map featuring 0.2-meter contour line intervals, detailed floor plans of the buildings, and front and side view elevations of the structure. These outputs provide our client with a comprehensive and detailed understanding of the site, aiding in their remodeling endeavors.
