Engineering Surveying

At New Global Geographics we have a background in design engineering, contracting and civil engineering projects, giving us a detailed understanding of the survey needs and requirements of the design team. As experienced engineering surveyors, we have a proven record of providing accurate engineering surveys for use in design and construction of structural, infrastructure, transportation, environmental and civil engineering schemes.

We can provide accurate and reliable dimension data throughout the construction process from the base topographical survey, cross-sections and ground modeling information to cut and fill calculations, dimensional control to setting-out on-site and finished as-built drawings. The range of projects undertaken have also include more specialist engineering surveying such as railway projects, coastal erosions, tunneling and restricted access site.

GPS Surveying

GPS (Global Positioning System) Surveying is the most advanced positioning and data recording technology available to the Land Surveyor today. Using available Satellites (Minimum 4), the Receivers record satellite signals and internal receiver software, sub-centimeter accurate horizontal and vertical positioning data is provided about any point or feature. This data can be related either to the National Grid Co-ordinate system or to your project’s own Local Grid.

The recorded data can be processed and manipulated by various software applications, depending on client requirements. The processed data is then available to the Project Team in various forms to ensure everyone has the highest quality information to hand.

The satellites send signals to earth; GPS receivers on the ground pick up these signals. The receivers use the signals from a number of satellites to calculate their own position on the earth’s grid reference system with accuracy ranging from 15mm to 35mm depending on the equipment used.

The equipment we use is mainly the Trimble R10 GNSS GPS and Leica VIVA GS 15 GNSS GPS Smart System with back-up if necessary using Trimble R8 GNSS Model 3, dual frequency, RTK (Real Time Kinematic) system. These are versatile systems, which are capable of bringing control points accurately to the site.

Topographic Surveys

When developing or redeveloping a property the architect / engineer / planner requires an accurate and comprehensive map of the site, indicating a wide array of relevant information. Exact ground elevations, roads, buildings, utility services, trees and significant landscape and drainage features are all indicated on a Topographic Survey. The map is produced according to strict requirements outlined by the municipal, county and other regulations. Our topographical surveys are carried out in accordance with the standard ‘topographical survey specifications’ as set by the Survey Department of the Concerned Municipality.

Surveys that are generally conducted along main roads and streets require great attention to detail. Along with our normal survey considerations, there are usually issues such as traffic and personnel safety to consider, especially where large amounts of time is required in the road, because of extra detail required such as; white lines, yellow lines, lane information and central reservation information. Roads are normally surveyed to extents of highway boundary, although clients sometimes require, with permission from property owners, to give them information on building positions of trees and other relevant detail when planning, large ‘above road’ structures.

GIS Data Collection

GIS software adds intelligence to spatial data, whether the data is generated in the field with GPS or remotely with lidar and photogrammetry. You can enter raw data, measurements, and field sketches directly into the GIS, enabling you to efficiently manage your data in a geodatabase with other spatial information.

You can use GIS technology for collecting, importing, converting, and storing spatial measurement and computational fabrics. You can integrate computations, such as COGO and traverse least squares, and preexisting networks as well as import spatial data feature classes and relationships.

With GIS software, you can bring data straight from the field into a geodatabase in a seamless workflow and take GIS data back into the field via a data collector or laptop computer. GIS software is customized to best meet your needs by optimizing functionality needed to complete a job.

3D Laser Scanning

Laser scanning is a relatively new technology, having been used as a precise survey instrument only since 1998. Now, it is quickly becoming the new industry standard as a way to make very accurate measurements in complicated environments. This is precisely why using this technology is the best solution for measuring as-built conditions inside buildings. The Latest Model in 3D scanner we have available here is the FARO Focus3D X 330, High Definition Scanner.

sc5

This instrument can collects survey data points at a rate of 50,000 points per second. It has an effective range of 400’ to 500’. With several “scan” setups inside a room or of a building, a complete 3D model can be made of the existing conditions. These models are then used to create 2D civil or architectural drawings, 3D computer models, and final survey documents.

The FARO Focus3D X 330 is specially designed for outdoor applications due its small size, light weight, extra-long range, extended scanning possibilities even in direct sunlight and easy postioning with to the integrated GPS receiver.

  • Distance accuracy up to ±2mm
  • Range from 0.6m up to 330m
  • Noise reduction 50%

Gate Level Computation & Fixing

The Gate Level Computation is often used for deciding the Gate Level of the Plot comparing to the nearest As-Phalt Road/Ground Level. The Gate Level Computation can be done using the GPS which is tied with the Concerned Datum like Dubai/Abu Dhabi etc and using the Automatic Level Machine, which is rarely using if the GPS is not receiving ay signals.

Our Standards will include:

  • As applicable, the survey will indicate interlock/asphalt/etc.. around the plot
  • At least two neighbor road levels or gate levels of 2 neighbors (if available) and if there is no asphalt road around the plot, then at least three points from the nearest asphalt road will be indicated
  • Photo records of the each plot.
  • Approval from the concerned Municipality.

In addition, we will provide the services for the Gate Level fixing in order to confirm the Municipality approved level for fixing the gate for the property on the site during the progresses of the construction and a filed report will be issued.

Demarcation Surveys

As qualified and experienced land surveyors we are constantly involved in every element of property boundaries and demarcations; whether it is positioning undefined boundaries or assisting in resolving boundary disputes between neighboring owners. Whatever the intended use, a combination of GPS (Global Positioning System) and Total Station equipment is generally used to carry out boundary surveys.

Boundary demarcation survey reports can be carried out for any one of the following reasons:

  • Property Sub-Division
  • Adverse Possession
  • First Registration
  • Boundary Setting Out
  • Rights of Way
  • Lease Plans
  • Boundary Disputes

GPR Underground Utility Survey

Radiodetection techniques are unable to detect non-metallic buried services such as plastic water and gas pipes, fibre-optics and drainage pipes that we cannot introduce a sonde into. To overcome this potentially hazardous situation, we combine the use of Radiodetection with Ground Penetrating Radar (GPR)

GPR is able to detect non-metallic as well as metallic pipes. It will also give an indication of the location and depth of buried services but will not identify them.

We have also been commissioned to used GPR on a number of occasions now to locate the extents of the roots of Cables, this is invaluable for a site where there are TPO’s in force in the vicinity of the development.

GPR does NOT trace services, but indicates the presence of voids, disturbed ground, trenches, pipes and cables under the surface. GPR works by emitting a short pulse of energy into the ground. Echoes are returned from the different interfaces between different materials in the ground.

The benefits of using Ground Penetrating Radar

GPR is able to detect metallic and non-metallic services such as polyethylene water and gas pipes as well as utilities such as fibre-optic cables which are not normally traceable using any other method.

gpr1

Using GPR alone we cannot guarantee finding or identifying all buried services, but when used in conjunction with Radiodetection the most complete answer available is produced.

Deliverables:

Deliverables would comprise an annotated drawing (DWG & PDF formats) illustrating the service location and a short form of a written report.

As-Built Surveys

Unlike many land surveys, done before buildings or other improvements are added to the land or after these additions are complete, as-built surveys are utilized during the middle of a construction project. Requested by many industries, as-built show improvements to the land, as they appeared in a particular point of time.As-built surveys may be used for commercial or residential properties. Surveys are crucial tools in the construction industry from the planning stage to the actual construction and future maintenance. A construction project begins with a site plan or plot plan, laying out the plan for the project from beginning to end. This plan incorporates any conditions already imposed on a given site.

As-built surveys are conducted several times throughout the duration of a construction project. Their frequency and the number of surveys undertaken depends on the scope of the construction project. The purpose of an as-built survey is to verify to local and state boards that the construction work authorized has been completed according to the same specifications set during the planning stage and shown in the site plan. The as-built survey is most often used to show the building inspector that a project under construction is conforming with zoning regulations. As-built surveys may be required for nearly every type of land project, from roads and trails to utility improvements and building construction.

Accurate as-builts are important not only as a bureaucratic measure. An as-built survey shows exactly what has been completed to date, a useful tool in adjusting the schedule of a large construction project. An as-built survey provides an important tool to manage the building as it is under construction and after it has been completed. As such, they may be requested by the project supervisor or others who are invested in the completion of this project. They may be used to document what has been completed by a specific date or work out payments to contractors, for example. Often they are used to verify the floor plan and evacuation plans, utility and cabling plans, or other subsequent steps in the building process.

Many forms of construction surveys, including some as-builts, are considered civil engineering, which may require additional degrees in addition to certification as a land surveyor. Within the field of as-built surveys, there are several survey types undertaken for very specific purposes. For example, a foundation survey ensures that the foundation is constructed in the right location on the plot of land, and has been built in the manner outlined in the site plan. Once the project is under construction or after it has been finished, a Deformation Survey can determine if it is changing shape or moving over time by creating a three-dimensional image of the structure at two different points in time.

Update Surveys

We can return to site and update surveys to reflect subsequent changes as and when required. When carrying out topographical surveys our surveyors generally establish plenty of site control (particularly away from the working area), that can be used later to re-establish on site to the original site datum & grid. This is also helpful to the site contractors as datum / reference points in more secure areas. Permanent Ground Markers (PGMs) / Earth Anchors can also be installed if required.

We can attend site and update surveys carried out by others, if required, by utilizing their site control, using survey station data as provided by the client. In certain cases the control may have been destroyed by site activity etc.. If this is the case, we will do our best to help, by utilizing GPS equipment or resurveying points of detail as required.

We are often asked to return to site to carry out update surveys, where material is constantly being moved to the site, for example; quarries & land-fill sites, and also construction sites where new site levels have been established

Measured Building Surveys

sc11

As a task specific investigation or part of an integrated measured building project, Survey Solutions can provide accurate structural details of key elements in buildings and strctures. Taking detail observations we can produce sections through any alignment to clearly show the various elements and how they relate to each part of the structure in position and level.

GPR Radar surveys can be used to map and position structural details such as rebar, reinforcement mesh and steelwork within the floors, walls and columns of concrete structures to locate existing features to confirm construction processes or avoid striking.

Data can be collected in a number of ways: The tried and tested method, generate an accurate building footprint with internal control points and then sketch and measure the internal layout before constructing the CAD plan from measurements recorded during the site visit.

Using hand-held computers and tablets the surveyor can input spatial data directly from a reflectorless Total Station, hand-held Bluetooth laser measuring device, or manually from a steel tape, constructing and verifying the bulk of the survey whilst on site.

Utilising our own 3D Laser Scanners, facades and structures can be accurately captured in a matter of minutes before being imported into our specialist software systems and converted into 2D CAD drawings or 3D models in CAD.
