At present we believe the three main tank construction challenges are:
Location
Construction methodology
Construction costs

LAGUNA Project Challenges - LocationLAGUNA Project Challenges - Location
Three unique locations which are all underground, each of which present individual access restrictions
Access restrictions will impact on design, construction method, construction duration and costs
Working environment will have to be carefully considered with regard to the health and safety of the workforce

LAGUNA Project Challenges - LocationLAGUNA Project Challenges - Location
The size of the cavern and the access tunnels or shafts providing access to it will restrict and determine:
Transportation of the tank components to the workface
Limitation of height and work area within the cavern
Lay-down areas for materials and construction equipment
Available size and type of lifting equipment
Allowable construction sequence of other works

LAGUNA Project Challenges - MethodologyLAGUNA Project Challenges - Methodology
Proven above ground construction methods can be transferred and adapted to below ground working
For each location under review we will have to consider:
Developing cavern and tank design concurrently to establish most suitable solution
Tailoring tank design to construction methodology as well as location
Best fit tank construction method
Integration of the above methodology with regard to other services required, e.g. piping, EC&I, etc

LAGUNA Project Challenges - CostLAGUNA Project Challenges - Cost
Construction costs will be greater than an equivalent above ground tank
Construction costs must not become prohibitive for the project
Major challenge will be to reduce these costs to an acceptable level

LAGUNA Project Challenges - CostLAGUNA Project Challenges - Cost
Minimising construction costs will be possible by ensuring that:
An integrated design and construction team is developed at the earliest possible stage of the project
All operational and maintenance requirements are understood at outset of design
Current above ground storage tank construction technology is used wherever possible
Automated construction equipment is used wherever possible to reduce labour resource required
