Method Of Statement for Survey Works

(1) – Purpose

This statement outlines the procedure for conducting thorough site surveys of installation facilities and civil works in accordance with project specifications. It includes technical specifications, procedural instructions, and quality control criteria for creating comprehensive site plans for engineering drawings of upcoming projects, or detailed feature mapping of completed facilities. Method Of Statement for Survey Works.

Method Of Statement for Survey Works

(2) – Scope of Work

The project will include the surveying of slope embankments and ground levels utilizing GPS / TPS survey methods as deemed appropriate by the Contractor.
Additionally, the project will entail mapping the topography of the site with respect to a fixed datum – Ordnance Survey GPS Active Network.
All activities will adhere to the guidelines and protocols that govern contractors operating within / on the site, which will be provided during the induction process.

(3) – Hazards Identified

The dangers associated with working in the environment will be outlined in the risk assessment, which include, but are not restricted to.

Underfoot Conditions: Slip/Trip Hazards
Moving Vehicles/Machinery.
Overhead Services.
Stockpiles.
Open Water Bodies Adjacent to site.
Vegetation.
Public Vehicles.

(4) – Equipment & Tools

The following equipment shall be used to the undertake survey:

Leica Smart Rover GPS system or the any other suitable brand.
Leica TS15 Total Station or the any other suitable brand
Leica auto level or the any other suitable brand.

(5) – Working Methods

All survey work will be conducted by the surveyors using GPS Survey receivers, Total Stations, and Auto-level, or any one of them as appropriate.

Sufficient detail must be surveyed to determine the overall topography of the site.

The level detail should be recorded at intervals of 100, 50, 20, or 10 meters, depending on the specific area being surveyed.

All survey instruments must be positioned in a way that minimizes disruption to the ongoing work and ensures the safety of the workforce.

The surveyor should adhere to the safety guidelines provided by the site management team, working within the designated ‘zone of safety’ and maintaining constant communication with the site management staff.

The surveyor is responsible for establishing survey control points to facilitate the collection of all necessary data. New control stations should be installed, marked, and documented according to client specifications.

These stations should be located in GPS-friendly areas with clear sky visibility to reduce errors and interference.

In case of any extension of the survey area, a minimum of two control points must be established within the new boundary. For total station work, the instrument should be set up over a known point, referenced to another known point, and a check measurement should be observed and recorded.

The collection of topographic data should be done systematically to ensure efficient data collection and the safety of the surveyor.

All control stations must be observed for at least two epochs of 3 minutes each, with a minimum separation of 20 minutes.

The control stations can utilize either a quick-release tripod or a wooden tripod for stability.
