Measured building survey
Trafford Palazzo, Manchester

Laser scanning delivers essential floor plan data to meet retail safety standards

Surface regularity is a critical factor in ensuring the safety and functionality of retail unit floors. The British Standard has clear definitions on surface regularity, which is why we were asked to produce a measured floor survey of three retail units in Manchester’s Trafford Palazzo shopping centre.

A leading retail brand already occupies 65,000 square feet of retail space in the centre, but was interested in creating a homeware store in three empty units on the ground floor. The property’s owners, Peel Land and Property, requested a floor level survey of these units to ensure it meets with retail standard SR2. SR2 allows for a tolerance of plus or minus five millimeters over a two-meters span. Therefore our task was to provide floorplans with level readings at two meter intervals.

One of the units presented a challenge due to the presence of debris on the floor, but this was addressed with the use of laser scanning technology. The laser scanner’s automated capabilities enabled it to identify and navigate gaps around debris and objects on the floor, whilst also eliminating the potential for human error and ensuring the accuracy of our results.

Benefits of laser scanning.

  • Using a laser scanner offered several advantages over traditional surveying methods, such as a total station.
  • Speed: Laser scanning is notably faster than traditional methods, allowing us to complete the survey efficiently
  • Accuracy: The laser scanner’s precision ensure that we met the strict SR2 requirements, delivering reliable data to our client.
  • Future-proofed data: Laser scanning captures comprehensive data, enabling us to provide additional measurements or readings if required by the unit’s owner or occupier in the future, without the need for a return site visit.

Upon returning to our office, we processed the raw data using specialised software. This software allowed us to create a 2D floor plan and a grid that included the required level readings at two meter intervals. Additionally we generated a heat map to provide visual representation of the data, aiding our clients understanding of the surface regularity of the units and helping the retailer make informed decisions regarding the expansion of their space.
