Calling For: Slurry Wall Solutions

Abstract Slurry cut-off walls are increasingly being used to control groundwater flows for geo-environmental or geotechnical purposes. The most important performance criteria of slurry cut-off walls are strength and permeability. This criterion makes it costly and time consuming. The objective of this problem statement by HSL Constructor Pte Ltd is to create an open platform for renowned international consultants (individual / firm) to submit a proposal on an alternate solution for cement bentonite slurry cut-off wall that overcomes the existing limitations. Problem Statement Addressing all limitations of a cement bentonite slurry wall in terms of permeability, durability and constructability, a suitable alternate/feasible/cost-effective option for slurry cut-off wall shall be developed and submitted including but not limited to the following considerations. 1. Hydraulic conductivity / permeability criteria less than 1 x 10-9 m/s 2. Unconfined Compressive Strength (UCS) - greater than 100KN/m2 and less than 300KN/m2 Submittals & Remuneration We welcome suggestions of alternate solutions for the mentioned problem statement and please contact us with your detailed profile/track records on or before 31st Jan 2018 via email. Remuneration will be commensurate with the professional proposal that meets our objective and specification criteria.
