About

Tim Nzali

Calcis was founded by Tim NZALI. Tim has qualifications in Geophysics, Hydrogeology and Engineering geology, with 20 years' experience in a broad range of projects in Europe, Middle East and Africa.

Tim started his career as geologist, working on magmatic and metamorphic rocks. He has worked as Hydrogeologist and Engineering geologist with two main activities: (1) modeling groundwater flow and contaminant transport and (2) acquisition, interpretation and integration of geological, geophysical and geotechnical data for engineering projects and quarries.

Tim has spent a few years working on port and coastal development projects focusing on wrecks and unexploded ordnances detection, seabed investigations for dredgeability assessment and geotechnical investigations.

Before founding Calcis, Tim was responsible of on land site investigation and has handled training of on-site geotechnical operation supervisions.

 

Mission

It is well documented that insufficient investigation can result in misleading information and can create the risk of not finding hazards and unknown geological conditions. It is also known that with inaccurate and unreliable geotechnical information, design and planning decisions may be incorrect. These situations can seriously delay or stop construction works with claims and costly consequences.

Ideally there should be no condition that comes as a surprise during construction. On the opposite, the most comprehensive site investigation cannot hope to reveal all the significant geological features.

Therefore, Tim, with a large multidisciplinary site-based experience, has founded Calcis to conduct two main missions for clients:

  • To make every effort to acquire high quality and reliable ground information;
  • To deliver an engineering geological model, synthesis of all available data of a site, consistent with the principles of value engineering.

In other words, Calcis's mission is to reduce ground risk and allow leading a safe and economic engineering project.
