About Us

Geospatial Surveying, Engineering & Construction Services

Our History

Construction Technological Services (CTS) was established in 1994 by our founder and former Managing Director, Mr. D.M. Thilakarathne. Initially, Mr. Thilakarathne founded CTS to provide specialist engineering survey-related services to clients in the private and public sectors. In 2013 we developed a strong relationship with the public sector in their irrigation engineering projects.

Subsequently, the company was involved in the engineering survey and design aspects. As a result, CTS has adopted the most advanced technologies in engineering surveys and strengthened its human resources with the most experienced and capable workforce.

Being involved in such nationally significant projects meant that interest in our company and the services we offer expanded substantially, enabling us to become the multi-disciplined engineering consultancy we are today.

The growth and success of CTS is driven by an absolute focus on two groups of people; our clients and our employees. We intend to form long-standing partnerships with our clients, supporting them with industry-leading solutions to their problems and an unrivaled level of service. In addition, we recruit the best people in our industry, support them in developing their skills and encourage them to grow with the business.

CTS Provides Engineering Consultancy services for Construction Projects. This includes conducting preliminary surveys, environmental and social impact assessments, initial estimation and design, bathymetric surveys, topographic surveys and construction services. In Addition, CTS provides design and estimate services for Irrigation projects.

Drone Surveying

Using Unmanned Aerial Vehicles (UAV) for Surveying has driven modern surveying into the next era. It's relative cost-effectiveness and the capability to capture data with multiple sensors such as RGB, multispectral cameras, or LiDAR sensors has allowed surveyors to bring surveying into the 21st century. In addition, drones can capture data in hazardous, hard-to-reach places with unparallel detail and accuracy. CTS has been an early adapter and the pioneer in the Sri Lanka drone survey segment.

Monitoring

Structural and Geodetic monitoring is vital in keeping lives safe while increasing environmental well-being. CTS provides tailor-made manual and automated monitoring systems for projects depending on their client's needs. CTS uses modern geodetic and geotechnical instrumentation and software to monitor and study structures. In addition, CTS has established monitoring systems for structures with national importance.
