Trustworthy survey data provides the project teams with a standard of reference to use in planning, construction, measurement and handover. Co-ordinates, levels, limits, features on the site and works done should be recorded and shared in a way that designers, contractors and clients are able to make decisions based on the same site information.
Best international contracting Company offers land survey services to Saudi Arabia project owners, contractors, consultants as well as industrial facilities to have defined construction and site requirements. Our survey staff assists in topographical mapping, setting-out construction works, and level control, underground utility location support, and as-built documentation and GNSS-based control work in accordance with the agreed scope.
All surveys are initiated with the purpose required, coordinate system, control information, accuracy, deliverable format and area of work. The results of the surveys are dependent on the available circumstances and information during the work. The interpretation of the design, certification of legal boundaries and engineering approval are not part of the contract unless stated otherwise by the pertinent authorised authorities.
The needs of the survey evolve during the project life. Initial work can be on the existing terrain features and site features. Construction phases involve setting-out, level checks and verifications. Final coordinates, elevations, dimensions and as-built drawings may be needed to complete the final closeout.
Since KSA project teams are a construction survey company, they may be assigned to appropriate projects as required, BIC liaises the work of the survey with the approved drawings, site access, workfront release, control points, required tolerances and reporting process.
Work on surveys cannot be carried out based on unconfirmed sources. The approved coordinate system, benchmark, grid, datum and control network should be identified by the project prior to the establishment of construction points.
Topographic Surveys
A topographic survey takes note of the visible topographic features and ground levels of a specific area. The survey can capture spot levels, contours, roads, kerbs, structures, fences, drainage, utilities visible on the surface as well as other pertinent objects depending on the extent of the area covered.
The customer must ensure the necessary boundary, grid spacing, contour interval, coordinate system, feature list and output format are required in case of a topographic survey Saudi Arabia project. Access restriction, traffic, standing water and concealed features may influence what is captured, vegetation.
Construction Setting-Out
Construction setting-out conveys approved information of the design to the site. It can contain building lines, column centres, foundation points, road alignments, utility routes, levels and offsets, anchor positions and other specified references.
The drawings that are issued should be approved to be built and in line with the project control. BIC defines the agreed information and establishes the differences where there is no agreement on coordinates, dimensions or levels.
Level Surveys and Benchmarks
Level surveys facilitate excavation, formation, concrete, roads, drainage, installation of structures and equipments. Approved references ought to provide temporary benchmarks and levels which should be guarded in the course of work.
Accuracy required, closure checks and identification of benchmarks and the need to have independent verification before critical construction should occur should be defined in the project.
Route and Alignment Surveys
Linear works such as roads, pipelines and utilities, fences and other works might be in need of centreline, offset, chainage and profile data. The points and intervals required is dependent on the approved construction and design process.
The results of the survey can consist of coordinates, longitudinal profiles, cross-sections and setting-out data where these deliverables are given in the scope.
Underground Utility Survey Support
The available services below the ground can impact on excavation, piling, foundation, road works and construction of utility. An underground utility survey Saudi Arabia project might be a combination of the available records, visible features on the surface and approved detection methodologies to identify or trace available service routes.
The outcomes of the detection process ought to be handled within the mentioned limitations and confidence. Deep, non-metallic, congested and inactive services, or poorly documented ones might not be identified reliably. Prior to excavation trial holes or other verification may be necessary.
As-Built Surveys
As-built surveys are used to document work that has been completed in such a way that the project can compare the positions, levels and dimensions that have been constructed with the approved requirements. Appropriate assignments can include foundations, structures, roads, utilities, chambers, and pipelines, equipment bases and other finished work.
BIC offers as built survey services which KSA project teams may utilize to verify progress, and provide inspection support and closeout documentation. Before starting the survey, the necessary items, tolerances, format of drawing and approval procedure must be verified.
GNSS Control and Coordinate Surveys
Where sites and satellites are favorable, GNSS equipment can be used to aid in control establishment, site grids, transfer of reference points, large area surveys and capture of coordinates.
The GNSS survey service we plan to execute in Saudi Arabia will be based on the project coordinate system, accuracy required, control available, method and quality checks of observation. The approach chosen can be influenced by obstructions, buildings, structures, interference and limited visibility of the sky.
Quantity and Progress Survey Support
Data of surveys can assist in the determination of the defined measurement of excavation, filling, stockpiles, completed surfaces or progress areas. The data collection must be agreed on before the actual data is collected by the measurement method, reference surfaces, boundaries and calculation responsibility.
The authorised project parties have the commercial certification and contractual approval of the quantity. Survey data give quantified data within the scope of the agreement.
Service boundary: Measuring survey, setting-out and survey deliverables are discussed on this page. Their dedicated services are still on civil construction, excavation, ground improvement, foundation work, road construction, utility installation and engineering design. Legal cadastral or boundary certification is only provided where authorised appropriately and indicated.
Topography data is usually demanded prior to design, tendering, site development or modification work. The survey ought to be representative of the agreed area and it should contain the features that are of interest to the planned project.
The field observations of BIC are planned based on the access, visibility, traffic, terrain and detail required. Site features are captured with control and reference points being checked. The restriction is noted where access is unsafe due to areas or features are hidden.
The final deliverable can be in the form of survey points, contours, drawings, coordinate schedules or digital data as per the agreement. When the customer orders the file, they should verify the type of file they require, the layer names and standard of the drawing prior to production.
The surveys of construction join the approved drawings and physical work. Surveyors should be able to work based on existing revisions, know the amount of point or line that is needed and communicate references in such a way that the site team understands it unambiguously.
Being a construction survey company that the KSA customers can address to a specific construction project requirement, BIC can assist in preconstruction control checks, setting-out, the establishment of offsets, the transfer of levels, work-stage verification and the measurement of the completed works.
Design modifications on-site are not approved by the surveyors. In case drawings do not conform, control points are disrupted or the real condition does not match the information issued, the project needs to give technical guidance prior to the provision of revised points.
Utility detection is a risk-reduction measure, and does not guarantee that all buried services will be located. The available as-built drawings, operator records, visible chambers, markers, route knowledge and detection equipment are to be taken into consideration.
In the survey plan, the services of interest, the area of investigation, and access, the format of required marking or drawing and whether suspected routes or not should physically be verified should be discussed. The results can be indicated on the ground, as survey points or on a utility plan.
The concerned project team ought to utilize the necessary permit, clearance and verification procedure before excavation or drilling. In cases of uncertainty, controlled trial excavation might be required under a different approved civil-work.
The collection of as-built information needs to be made at the appropriate stage. The underground utilities, embedded objects and hidden work can be to be surveyed prior to being covered. Delays due to the need to wait till its completion may render significant details unavailable.
BIC is capable of documenting the completed coordinates, levels, dimensions and visible features to the agreed survey schedule. The client is expected to determine the assets needed to be surveyed, the naming system needed, tolerance, process of drawing revision and format of closeout.
As-built survey data records conditions which are observed. It is not itself an affirmance of the performance of the engineer or of the quality of the material or of an acceptance under contract unless such performance or quality performance is specifically specified.
In cases where the site is in an area with good satellite visibility and the accuracy needed is reasonable with the observation technique, GNSS techniques will enhance efficiency. They are especially effective in controlling sites, far-off topographical projects, roadways and distributed project characteristics.
The coordinate reference system, transformation parameters, quality of control, length of observation, source of correction and field verification should be taken into consideration in the survey method. Checks against approved control are independent checks that are used to detect reference or setup errors.
Where buildings, heavy industrial machinery, limited sky visibility (or interference) with GNSS accuracy, total-station or level-based techniques can be employed alone or together.
Control should be clearly identified in all the work on project survey. Accepted control points should be given by the customer or he must authorise the process of establishing it. The physical condition and datum information should be recorded as well as the description of points, coordinates, levels and so on.
Control points should be excavation, traffic, material storage and construction disturbance resistant. It should not be assumed that replacement or transfer based on a single observation, but this should be checked via an approved survey procedure.
Coordinate system mixing, local grids, drawing grids and geographical coordinates may result in severe site errors. Project survey basis must be agreed in writing prior to the commencement of setting-out.
The survey instruments are chosen based on the task to be accomplished, accuracy, distance, visibility, environment and deliverable. Appropriate assignments can involve the utilization of total stations, digital levels, GNSS receivers, utility-detection devices and data-processing software.
The equipment must be properly maintained and verified as per the project need. This should be done through field procedures that entail setup checks, backsight or reference checks, closure or repeat observations and proper data backup.
The way must be work front practical. Technologically advanced instrumentation does not eliminate the necessity of stable installation, visibility and good control as well as proficiency in the field.
Accuracy needed is dependent on the activity. Topographic mapping (in general), earthwork levels, location of structures, anchor location, equipment location may be in very different tolerances.
The investigation must include the necessary tolerance and acceptance. In cases where the drawings or specification does not spell this out, then the matter needs to be clarified prior to fieldwork.
The values observed should be differentiated with the design values and any deviation in the agreed format should be identified in survey reports. The authorised project team can still decide on the acceptance or corrective action.
Majority of the time surveyors have to work around traffic, mobile equipment, excavations, facilities in operation, uneven ground and construction in progress. The site permit, access and safety arrangements should be coordinated with survey activities.
The work plan must take into account the line-of-sight requirements, exclusion zones, banksman support, work at road crossing, confined restrained areas, night work and instrument protection control point protection.
Safe and unauthorised places should not be entered just to make a measurement by survey personnel. A different position on observation or an amended work arrangement ought to be negotiated in which access is limited.
The field observations have to be done and presented in a manner that can be reviewed and utilised by the project. Examples of deliverables can be coordinate schedules, level sheets, point reports, topographic drawings, utility plans, cross-sections, as-built drawings or digital survey files.
Before the preparation of the deliverable, the file format, drawing template, precision of coordinates, units, structure of layers, naming convention and revision requirement should be agreed upon.
Checking Survey data must be done to ensure that they are complete and consistent. It should be made known any assumptions, areas or limitations that are inaccessible.

BIC views survey work as a controlled project service, which links approved information, field observations and deliverables to be used. We establish the purpose of the survey along with the output in advance of mobilisation so that the field team gathers information as required by the project.
Our experience in civil contracting assists our survey teams to have knowledge on construction sequencing and work front interfaces. Survey services will not be dependent on the scope of execution unless the two are part of a well-organized proposal.
We also have a clear separation between survey measurement, design responsibility, legal certification and construction approval to ensure the customers are aware of what the service entails and what it does not entail.
The land survey enquiries may be consulted in regard to appropriate projects in Saudi Arabia. Projects in the wider Eastern Province of Jubail, Dammam, Khobar and other areas can be evaluated based on scope, access of site, control information, mobilisation of equipment, deliverables and programme as well as projects in Riyadh and Jeddah.
The BIC is able to assist topographical surveys, setting-out of construction, level survey, route surveys, utility survey support, as-built surveys, GNSS control and defined quantity measurements.
Yes. Drawings, coordinates, benchmarks and project control information may be used to complete setting-out.
Yes. The enquiry should also include the necessary boundary, features, and contour detail, coordinate system and deliverable format.
No method guarantees detection of every service. The project risk controls should be used together in terms of available records, surface evidence, detection results and physical verification.
Survey has to be done prior to the covering of concealed work and at various other phases that the project close up schedule demands.
The suitability of GNSS is based on the visibility of the satellites, interference, quality of the control and accuracy needed. In case the conditions do not allow it, other instruments can be employed.
Cadastral or property-boundary certification Legal Cadastral or property-boundary certification is only provided where the authority required, records and professional authorisation, is provided and indicated in the scope.
Depending on the task, deliverables can be in the form of coordinate lists, level sheets, point reports, drawings, profiles, cross-sections, utility plans and digital survey files.
