The BAM Construction<\/a> team (part of the Royal BAM Group) used FARO<\/a> laser scanning hardware along with FARO\u2019s BuildIT Construction software to demonstrate construction compliance<\/h2>\n

BAM used FARO laser scanning hardware and the BuildIT Construction software to showcase how the construction was in compliance with the strict specified dimensional tolerances, subsequent to the construction of the concrete pool tank and before the pool\u2019s tiles were fitted to ensure critical success factors of the project.<\/p>\n

Upon opening in 2019, the impressive new \u00a326m Dover District Leisure Centre will feature a competition standard eight-lane swimming pool \u2013 and for competition swimming pools, build accuracy is paramount.<\/p>\n

Appointed in 2016, BAM Construction was charged with delivering a first-class sports facility over an extensive site \u2013 they knew a good quality build was going to involve an element of BIM process<\/a> supported by technology to quickly verify asbuilt pool dimensions and closeout risk.<\/p>\n

In addition to the standard features of pool design such as ensuring that the structure is obviously watertight and can withstand the pressure generated by the volume of water, as it is a competition pool, a variety of other criteria needed to be met. Demanding dimensional tolerances state that the pool\u2019s walls should be parallel and at right angles to both the swimming course and the water surface and that the pool length should be certified. In elite sporting events, poor construction tolerances can mean the difference between gold and silver\u2026<\/p>\n

The structural engineer provided their model which formed the basis of the setting out and construction of the pool tank.<\/p>\n

Furthermore, throughout the construction period, a collaborative effort from the design team resulted in a well co-ordinated, project information model of the facility.<\/p>\n

The BAM Construction team then added 4D (time) related data to the project information model to demonstrate the build programme and to ensure the logistics were planned effectively to ensure deliveries and subcontractor trades were in line with the programme.<\/p>\n

Subsequent to the construction of the concrete pool tank and before the pool\u2019s tiles were fitted, BAM Construction team used FARO laser scanning hardware along with FARO\u2019s BuildIT Construction software to demonstrate that the construction was in compliance with the dimensional tolerances required.<\/p>\n

Daniel Brenchley, BAM construction project manager, commented: \u201cThere would have been considerable time and cost implications if dimensional errors in the pool were found after the tiles were fixed, great care and attention was paid when forming the pool tank.\u201d<\/p>\n

BuildIT Construction allowed BAM to verify as-built dimensions.<\/p>\n

The design team had specified tile thickness and the nominal adhesive thickness required enabling BAM to build the pool tank to meet the finished dimensions.<\/p>\n

Brenchley continues: \u201cIn accordance with our \u2018right first time\u2019 objectives, to confirm that all of the faces of the pool tank were correct and that no \u2018buckling\u2019 had occurred after the removal of the pool tank formwork, prior to tile fixing we conducted a detailed laser scan<\/a> of the pool tank\u2019s faces and used FARO\u2019s BuildIT Construction software to make comparisons with our 3D model.<\/p>\n

\u201cOur construction approach was vindicated by the results achieved by the laser scans and the reports delivered by our BuildIT Construction software. As we\u2019d planned, no pool tank wall \u2018intrusions\u2019 were found, but several shallow \u2018hollows\u2019 were detected.<\/p>\n

Through the use of BuildIT Construction, the identified areas were highlighted in a graphic report and the accurate XYZ coordinates of the hollows enable the team to precisely locate the areas and resolve the issues.\u201d<\/p>\n

As the process of scanning and verification using BuildIT Construction software is so quick and effective, BAM was able then to repeat the procedure to demonstrate once again that the completed, tiled pool met the stringent Olympic certified criteria.<\/p>\n

This single rapid and repeatable, on-site workflow enabled by the use of FARO\u2019s BuildIT Construction software at the Dover Leisure Centre pool consisted of:<\/p>\n
