You and the planners can therefore be totally sure of what you will be getting before we make anything.

We are happy to offer you alternatives and to work with a range of materials to suit your needs. We can provide a turnkey solution including foundation design and installation of the structure.

Structural ServicesSite/Tower Survey & Structural Analysis

FLI have a strong engineering team, with all work being carried out, or supervised, by Chartered Engineers. We are able to offer many consulting/design services including:

· Analysis of standard products to support a non-standard loading configuration· Structural Analysis· Site Surveys· Geotechnical Surveys· Foundation Design· Tower surveys

Structure Installation & Rigging Kits

With dedicated installation teams and a manufacturing labour force also trained as installers, FLI can install any of our structures or provide guidance to our customers installers.

In addition to standard erection using a crane, FLI are also able to offer a hand installation service for some of our structures. This type of install requires the use of specially designed ’Derrick’ poles that are used to lift either elements or modules into position. These rigging kits are also available for sale to other installation companies and are supplied with detailed drawings & method statements describing their use.


Additional ServicesFLI can provide you with a full turnkey solution, with additional services listed below. Upon review of the borehole data, one of our Chartered Engineers will innovate a solution to your specification. Our focus on innovation has been recognised by Network Rail, with FLI winning the Innovation Award in 2009.

Geotechnical InvestigationsSite / Ground Investigations are carried out by us in accordance with the specifications for deep pile foundations, i.e. to minimum depth using dynamic probes and window sampling rigs.

Pile TestingTension, compression and lateral pile load testing is available. Sacrificial piles can be installed and tested to failure if required.

Steel FabricationOur fabrication workshop contains state of the art CNC machinery for efficient & quick production. Welding is carried out by Lloyd’s Certified welders and all our products carry CE certification.
