Q Q Fast production (150 m per rig shift) enables clients choosing to fast-track their project to reduce P&Gs and bring forward cash- flow generation from early completion (e.g. tenant occupancy rent). Q Q Restricted access sites: Q Q Fewer personnel undergo (often lengthy) on-boarding Q Q On-boarding schedule can often be shortened, enabling faster overall works completion at a lower overall cost to the client. Q Q Where site entrance, headroom and/or working space is limited: Q Q Compact TRM piling rigs can enter 3.5 m width/height and install piles under 7 m headroom Q Q Versatile TRM piling rigs can access tricky working posi- tions (e.g. in site corners, between live overhead electrical cables, or past exposed service pipes) reaching down into pilecap excavations. Q Q Sites with variable and/or challenging soil conditions and/or limited geotechnical information: Q Q Encountering unexpected, unstable soil and/or shallow ground- water has no impact on TRM pile installation speed or cost, avoiding potentially significant delays and expenses incurred by other piling systems using casings or slurries Q Q Simply adding TRM pile segments overcomes unexpected deeper bedrock, with pile depth automatically adapting to the in-situ bedrock level and quality at each pile position Q Q The versatile TRM Piling System is not deterred if actual geo- technical conditions differ from those expected and, if required, can seamlessly switch design and installation between end- bearing and friction piling systems in minimal time and without major additional costs. Q Q Sites with existing adjacent structures sensitive to vibration from piling works: Q Q The TRM piling system is virtually vibration free, making it an ideal choice near heritage buildings. OTHER NOTABLE VERIFIABLE BENEFITS Other notable, verifiable benefits enjoyed by clients who choose TRM piles include: Q Q The TRM Piling System is inclusive of all pile head trimming works as TRM piles are cut off at the specified final cut-off level during the pile installation Q Q Being a full displacement piling system, TRM piles improve and compact sub-soil making no piling spoil or mess, making them advantageous at “reused” brownfield sites with possible soil contamination Q Q Lightweight TRM piling rigs significantly reduce the working plat- form preparations required Q Q Compact TRM piling rigs require less working space, enabling more rigs to be safely operated simultaneously on site to accelerate the construction programme Q Q TRM piles require far fewer site operatives than other piling systems Q Q Designs are performed in-house and signed off by a professional engineer (Pr Eng) at TRM Piling along with experienced design engineers at Tiroler Rohre GmbH in Austria, making reference to the substantial technical database compiled over 40 years of TRM piling projects internationally Q Q TRM ductile piles are approved and detailed in EURO codes and standards adopted in South Africa, and have been comprehensively tried and tested in African conditions, including many successful load tests Civil Engineering March 2022 5 TRM pile installation close to a running conveyor on a mine Rebar cage ready and placed almost immediately after pile installation TRM piling rig fitted with track pads allowing tracking along roads without causing damage to the road surface
