At Center Point Survey Work 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

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.
Our standard surveys are generally based on the following criteria:-
Horizontal and vertical controls are both arbitrary, unless required to be co-ordinated to the Ordnance Survey Grid System and Datum. Detail varies according to size and type of site and is always adjustable to the client needs. Our basic surveys will always include boundaries; trees with a diameter generally greater than 150mm will be measured and identified according to species; levels across the site are taken as a 10m grid with additional spot heights taken to account for undulating topography. Presentation is at scales from 1:50 to 1:500 depending on the clients' needs - typically on A3/A1/A0 size sheets of stable base material or colored paper copies. Digital data is supplied for use with AutoCAD in DWG/DXF and PDF formats.
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.
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-built 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-built, 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.
