Construction Survey Services

CCSO Services offer an adaptive and modern approach. We have a background in Civil Engineering and working on design projects. Using only the best technology, we guide commercial and industrial construction of new roads, buildings and structures, working closely with our clients. Our surveyors can rapidly collect large quantities of accurate, co-ordinated, three dimensional data, from the surface of remote features. With this experience we take great care with all our work and consider thorough checking of our work and data to be a large part of the finished process.

Types of surveys we carry out on Construction sites are:

  • Topographic
  • Structural staking (gridlines, piles, anchor bolts, bridges)
  • Civil surface works (site grading, concrete for structures, curbs and flatwork)
  • Earthwork quantity tracking and verification
  • High precision surveys and control networks
  • As-constructed reporting
  • As-built Survey
  • UAV (quantities, site progress reporting, asset management, aerial site imagery)
  • Structure Survey Control Points (high accuracy & precision with quality & assurance)
  • Volume Calculations
  • Stockpile Surveys
  • Drone Surveys

Future expansion for Construction survey services shall include:

  • Deep and shallow utility locating services (sanitary, sewer, water, gas, electrical, telecom)
  • Deformation monitoring
  • Terrestrial laser scanning (floor and wall flatness, feature location verification, site progress)
  • Construction layout and as-built pipes
  • Tunnel control and alignment surveys

HORIZONTAL CONSTRUCTION MONITORING SURVEY
(Roads, Bridges, Drainage etc.)

Horizontal and vertical construction surveys are developed to create a framework to which other surveys can be compared. The most fundamental aspect of a successful survey and all subsequent activities is accurate, reliable and precise survey control. It is highly recommended that Vertical Control and Horizontal Control surveys are used in the preliminary stage and also during the execution of a project. Specifically during the following construction phases: underpinning, dewatering, excavation & demolition. This enables construction teams to act quickly, if necessary, urgently make adjustments and changes where appropriate. Whether they are on the ground, in the open sea or at the top of a tall building.

CCSO specializes in obtaining all the required measurement and monitoring data, analyses materials, develops new methods and techniques, and transforms the resulting information into clear reports. Our ultimate aim is to achieve the highest possible degree of certainty.

CCSO works with our client during the construction planning phases to ensure all parties understand and agree, on the requirements for horizontal and vertical control datum. This reduces the likelihood of datum mismatch that can be extremely costly for any project. Lessons learned are transformed into solutions, which are then deployed to resolve new issues.

VERTICAL CONSTRUCTION SURVEY
(Building, towers & other vertical structures)

CCSO are looking closely at vertical alignment systems that perform better — more accurately and more efficiently — than traditional alignment systems based on optical surveying and/or laser plumbing. We have modern systems that take full advantage of current global navigation satellite systems (GNSS), data streams from inclinometers and other sensors, onsite communication systems and real-time computation are unquestionably better than traditional systems.

DAM SITE SURVEY & DEFORMATION MONITORING

Driven by progress in sensor technology, computer methods and data processing capabilities, 3D laser scanning has found a wide range of new application fields in recent years. Particularly, monitoring the static and dynamic behavior of dams has always been a topic of great importance, due to the impact these structures have on the whole landscape where they are built.

Geodetic displacement measurements have long played an important role in the analysis of structural deformation. The accuracy, versatility and capacity for self checking and accuracy analysis make survey measurements from equipment such as total stations a popular choice & important source of monitoring data for many years to come.

CONSTRUCTION STAKING

Construction Staking, also known as a Site Layout Survey, is the process of interpreting construction plans and marking the location of proposed new structures such as roads, buildings and any other structural footprint layout.

Construction staking is performed to ensure a project is built according to engineering design plans. The staked reference points guide the construction of proposed improvements on the property, and will help to ensure the construction project is completed on schedule, on budget and as intended.

Our measured building surveyors have live ‘on-site’ drawing technology giving us the ability to produce close to final drawings on site, thus enabling a high level check process.

Using Civil 3D survey processing software along with AutoCAD drawing software, we are able to produce in-depth, accurate drawings with a number of different survey outputs.

Route Alignment Survey

An initial survey to determine the alignment of the road should consider the most appropriate route. An alignment is defined by a series of points, lines and curves. In order to build a road, you need to know exactly where it is located on the earth. We use an alignment to show where that road will be placed. There is the horizontal alignment and the vertical alignment. Typically, the alignment follows the centerline of the road.

LINE AND GRADE SURVEY

When building roads, buildings, pipelines and other projects, it is a common task for surveying engineer to mark locations on the ground according to a project. The marks placed are usually wooden stakes. These wooden stakes serve as reference points for either vertical or horizontal positions, or for both.

  • The vertical location (elevation) is called grade.
  • The horizontal location is called line.

The line and grade must be established in a reasonable distance (1 to 3 m) from proposed construction prior contractor starts work. Craft persons (skilled workers) can draw positioning of constructions using rule and hand level then.

GEOTECHNICAL LOCATION SURVEY

CCSO offers Geotechnical location survey to locate the exact position of the borehole & test/trial pits. It includes the process of marking the location of proposed new borehole/test pit location.
