1. 1. Life Cycle Assessment of Borehole Thermal Energy Storage

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Saga Karlsson; [2022]
   Keywords : ;

   Abstract : Borehole thermal energy storage (BTES) is a technology used to store energy between seasons. It could therefore be a solution to the seasonal mismatch between the use and production of (renewable) energy, which can be used to increase energy efficiency and reduce greenhouse gas emissions.

3. 2. Pore water pressure and settlements generated from water driven DTH-drilling : - A field study

   University essay from KTH/Jord- och bergmekanik

   Author : Moa Asplind; [2017]
   Keywords : DTH drilling; hydraulic drilling; settlements; pore pressure; Venturi effect; Sänkhammarborrning; vattendriven borrning; sättningar; porvattentryck; Venturi effekten.;

   Abstract : Foundation work can cause damage to adjacent buildings and infrastructure. Drilling is performed in sensitive areas in urban projects and where the ground conditions are difficult. It is important to be aware of the installation effects from drilling. READ MORE

4. 3. Pore pressures and settlements generated from two different pile drilling methods

   University essay from KTH/Jord- och bergmekanik

   Author : Rasmus Ahlund; Oscar Ögren; [2016]
   Keywords : DTH; bored piles; pore pressure; settlements; over-drilling; sänkhammarborrning; borrade pålar; portryck; sättningar; överborrning;

   Abstract : For piling works in sensitive soil, especially in inner city projects, it is essential to be aware of the available methods and to choose the most suitable method to minimize the risk of damaging existing buildings or endanger the workers at the construction site. Down-the-hole drilling of piles is a relatively safe method and can be separated into drilling with air powered hammers and water powered hammers. READ MORE

5. 4. Uncovering Hidden Needs in Ground Engineering : Case Study of LKAB Wassara

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : IGOR KORDAS; [2016]
   Keywords : ;

   Abstract : Detta examensarbete utgick både från behovet av bättre förståelse för grundläggningsmarknaden av LKAB Wassara – ett innovativt företag som har utvecklat den nya tekniken av hydraulisk DTH-borrning; och från insikten att åstadkommande av kundnöjdhet genom uppfyllandet av dolda behov i byggbranschen är en lovande men samtidigt utmanande uppgift. Utmaningen som behandlas i detta examensarbete är tvåfaldig: dels leder de konventionella marknadsundersöknings metoder ofta till att de dolda kundbehoven inte erhålls, trots att dessa behov är mycket viktiga för produktinnovation; och dels är det en brist på fallstudier som utforskar de explicita eller dolda behoven i byggbranschen.

6. 5. Uncovering Hidden Needs in Ground Engineering: Case Study of LKAB Wassara

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Igor Kordas; [2016]
   Keywords : Hidden needs; customer satisfaction; ground engineering; Outtalade behov; kundnöjdhet; grundläggnning;

   Abstract : This thesis stemmed from the need for better understanding of the ground engineering market by LKAB Wassara - an innovative company that developed a novel technology of hydraulic DTH-drilling; and from the insight that achieving customer satisfaction through fulfilment of hidden needs in the construction industry is a promising yet challenging endeavour.  The challenge addressed in this thesis is twofold: firstly, the conventional market studies often lead to the hidden customer needs being lost, while these needs are important for product innovation; and secondly, there is a lack of case studies exploring the explicit or hidden needs in the construction business that might be partially explained by complexity of interrelations of products, services and stakeholders inherited to the construction market.
