How to Carry Out an Accurate Site Survey

336

An accurate site survey is essential to any construction plans. By getting it right the first time around, you can save valuable time and money by avoiding revisiting and remeasuring the site or creating inaccurate drawings. There are several rules in order to carry out an accurate site survey, which are listed here:

  1. Take the Right Tools

When it comes to embarking on a site visit, it is imperative that you take the right tools with you to complete your survey. This will include a camera, so that you can take detailed photographs of the whole site which you’ll be able to refer back to later and use in your CGIs. You will also need a notebook and pens so that you can draw sketches and write down any important information that comes up as you go. Most importantly, you will need to take the appropriate measuring instruments in order to get accurate dimensions for the site. Usually, this will include a laser measure or distomat, a tape measure, and possibly some more specialised items depending on the specifics of the site in question.

  1. Be Observant

There are a number of things that you’ll need to take note of when performing a site visit. These will include the current surroundings of the site, including roads, buildings, vegetation, architectural context, and any hazards that are in close proximity; access routes to the site and accessibility; the positioning of the site, in terms of which sides face the sun or get the best views; and circulation of traffic and pedestrians around the site, including any noise or pollution which occurs as a result of this. You will also need to consider how the materials, surfaces and levels of the site might affect your design, as well as the location of existing cables, pipes and drainage systems. Be sure to measure both the inside and outside of the building, including the roof heights, and get into the attic too where relevant. Sketches and elevations are often a useful way to create a visual that you can refer back to on returning to the office. You should take clear photographs of any brickwork which will allow you to count the bricks and make accurate measurements.

  1. Do Your Homework

Following your site visit, you will need to do some extra research. This will include finding information on the status and history of the site, such as whether it lies close to any listed buildings or conservation sites, as this may result in certain regulations being imposed. You will also need to inspect aerial images of the site using tools such as Google Maps, as these may reveal things that were unclear at ground level. Further research into the precise sun exposure of the site may also be useful.

When it comes to carrying out a site survey, accuracy is everything. Inaccurate measurements can cause innumerable issues further down the line, which will only result in the waste of time, money and resources. By taking great care in your measurements, being observant, and measuring absolutely everything, you can be sure to carry out an accurate site survey.
