How to Create a Survey Level Sheet:

 A Detailed Guide

 

Introduction 

Creating a survey-level sheet is essential for accurately recording and assessing the elevations and changes in a construction project. This guide breaks down the process into three main sections, each vital for documenting the details, intervals, and verification of the survey data.
 

 1. Detail Section
The first section of your survey-level sheet involves capturing essential project details. Here’s what you need to include:
 
Name of Layer: Specify the particular layer or surface being surveyed.
Change of the Layer: Note any changes to the layer since the last survey.
Date: Record the date when the survey was conducted.
Request Number: Include any reference or request numbers associated with the survey task.
Back-sight Reading (BS): The initial reading taken from a known point.
Bench Mark Elevation (BM): The elevation of a fixed point used as a reference.
Height of the Instrument (HI): The height at which the surveying instrument is set up.
 
 2. Measurement Intervals Section
The second section focuses on the intervals at which measurements are taken along the surveyed path. Typically, these intervals are every 10 or 20 meters. Include the following details:
 
Change Intervals: List the distances at which measurements are taken.
Height of Instrument (HI): Reiterate the height at which the instrument is set up for each interval.
Intermediate Sight (IS): Readings taken between the back-sight and fore-sight for additional points of interest.
Previous Level: The elevation from the last survey or previous reading.
Existing Level: The current elevation at each interval point.
Thickness: Measure and note the thickness of the material or layer at each interval.
Required Level: The target or desired elevation.
Difference: The difference between the existing level and the required level, which helps identify areas needing adjustment.
 
 3. Verification Section
The final section is for authentication and verification of the recorded data. This includes:
 
Signature of Site Surveyor: The surveyor who conducted the survey on-site should sign here to confirm accuracy.
Signature of Consultant Surveyor: The consultant surveyor’s signature is required for verification and approval of the survey data.

 

 Step-by-Step Process
1. Prepare the Sheet:
   - Create a template that includes all three sections.
   - Ensure enough space for detailed entries in each portion.
 
2. Fill in the Detail Section:
   - Start by entering the name of the layer, date, request number, and other relevant details.
   - Record the back-sight reading, benchmark elevation, and height of the instrument.
 
3. Conduct the Survey:
   - At each interval (e.g., every 10 or 20 meters), measure and record the height of the instrument, intermediate sights, and levels.
   - Calculate the difference between the existing and required levels to determine any necessary adjustments.
 
4. Complete the Verification Section:
   - Once all data is recorded, the site surveyor should review and sign the sheet.
   - Submit the sheet to the consultant surveyor for final verification and signature.
 
5. Review and Store:
   - Ensure all entries are accurate and complete.
   - Store the survey level sheet securely for future reference and project documentation.
 
By following this detailed guide, you can create a comprehensive and accurate survey level sheet that captures all necessary data for your construction project. This process ensures precise measurements, facilitates better project planning, and helps maintain high standards of quality and compliance.
