Its Electrifying!

Spie ENS have appointed ScrewFast to assist them in the delivery of the Kirkby Orrell project, on behalf of Electricity North West to design, supply and install a combination of helical piles and Grip piles for 41no. wooden transmission line foundations and associated anchor stays, on the Kirkby to Orrell line.

Our works commenced on site at the end of March 2014 and are scheduled to be completed within a 9 week programme.

Foundations for the Olympics – Our Statistics

  • Lee Valley – 12,000 seats, 1067 piles to 8m. (8.5 kilometres of tube installed, uninstalled and recycled)
  • Eton Dorney – 500 seats, 61 piles
  • Hadleigh Farm – 500 seats, 190 piles
  • BMX – 2000 seats, 118 piles
  • Water Polo Venue – The building housed the pool and 5000 seats. 405 piles to average of 8.5m (3.5 kilometres of tube installed, uninstalled and recycled)

Note all sites were installed, uninstalled and recycled.

We provided foundations for 20,000 temporary seats at the Olympics.

Design Smart Motorways

ScrewFast Foundations were appointed by Costain, on behalf on the Highways Agency, to undertake the detailed design of 70 no. helical pile and Grip pile foundations for the M1 J28-31.  Structures encompassing MS4′s, MS3′s and Portal Gantries.

The scope of works also includes the production of Approval in Principle, Departure From Standard and Geotechnical Design Report Addendum documentation.  The design work got underway In December 2013 and is scheduled to be completed by July 2014.

Design Magic

Halcrow Hyder JV appoints ScrewFast to M1 J39-42 Design Smart Motorways, to complete the detailed design of helical pile and Grip pile foundations, for:

  • MS4′s
  • Superspan Gantries
  • Secondary Cabinet Platforms
  • ADS/DS Signs
  • CCTV structures

There are 86no. structures in total.

The scope of works also includes the production of Approval in Principle, Departure From Standard and Geotechnical Design Report Addendum documentation.  The design work began in May 2013 and is scheduled to be completed and approved by May 2014.

Barking Substation

ScrewFast have successfully completed the design, supply and installation of helical piles and steel grillages at Barking 400kV Substation, supporting numerous structures throughout the site.  The works were completed in 2 phases spanning 2012-2014.

Comparisons where taken between the use of steel and concrete, considering the whole life and direct project benefits.  Helical piles demonstrated significant gains in Value for Money, Installation and Performance.

During the works, tests were performed to investigate the effects of stray current and the steel pile and grillage acting as sacrificial member. Following some collaborative design innovation with our client (SEESA) the tests conclusively removed any doubt of the possibility of stray current.

The SEESA Team at Barking Substation recently collected the SEESA Project of the Year Award. ScrewFast have been thanked for their valuable contribution to the scheme.

Portal Gantry Foundations.

Portal Gantry Foundations like MS3 & MS4 Motorway sign Foundations can be fixed using the traditional Concrete Pilling method however industry experts have, for quite some time, preferred to utilize ScrewFast`s Helical Pilling method due to massive savings in cost, manpower, materials, and time combined with the health and safety and ecological benefits that this process provides.

Helical pile Portal Gantry Foundations Support many structures that we encounter in our daily lives and provide completely safe, solid bases that can be rapidly installed at considerably less cost than their Concrete pile counterparts.

The above Road and Railway structures are a perfect example of situations in which the ScrewFast Helical Pile Portal Gantry Foundation method can be used in the modern world where safety, cost and rapid installation and removal are at the very top of the general public’s requirements and expectations.

What are GRIP Piles?

Piles are used in many forms of construction where deep, secure fixings are required in soil or rock for foundation purposes enabling engineers to safely and securely attach structures or materials to the protruding end of the embedded Pile fixing.

The patented steel GRIP Pile technology is a variation on the commonly used micro-pile offering a significant advantage over the micro-pile primarily due to the fact that its design negates the need for a grout pump.  Instead, GRIP Pile technology utilises a nylon tipped plunger which creates many times more pressure that any grout pump is capable of producing to force the site-mixed grout into the open pile tubing and out of specially designed exit holes, at the end of the pile tubing.

The extreme pressure created by the above mentioned GRIP Pile nylon-tipped plunger ensures that a competent and consistent column of grout encases the pile shaft in all types and consistencies of soil.

Cost effective Helical Pile Method for MS3 & MS4 Foundations.

For many years the standard procedure for MS3 Foundations and MS4 Foundations has been the tried and trusted method known as Concrete Pile. While this is form of foundation fixing is perfectly adequate for its intended purpose it is very time consuming and labour intensive compared to the ScrewFast Piling method for Gantry Foundations.

ScrewFast`s Helical Piling method for MS3 & MS4 Foundations can be completed form start to finish in 1/3 of the time that it takes to complete a project using the concrete piling method thus reducing the need for traffic management and inconvenience to motorists.

Compared to the Concrete piling method ScrewFast`s Helical Piling Method for MS3 and MS4 Foundations offer the following time and financial savings…

  • Time – The Helical Pile method offers a 66% time saving over the Concrete pile method and, unlike the concrete pile method the work can be carried out in all weathers.
  • Labour – ScrewFast Piling Method requires a 5 man team to complete the entire process compared to the Concrete piling method which requires approximately 16 workmen from various trades throughout the process.
  • Plant Hire – Helical Pilling greatly reduces the need for Plant throughout the entire process.
  • Soil Removal – Due to the fact that the Helical Pile method uses specially designed steel bars that are literally screwed into the ground it eradicates the need for soil removal before and after preparing the foundation.
  • Materials and Deliveries – ScrewFast`s Helical Pile method eliminates the need for concrete in the foundation and offers a massive saving on various other materials.

It is clear from the above information that there are considerable financial savings to be made by utilizing the Helical Pilling method when installing MS3 and MS4 Foundations; Savings that have transpired from using Steel over Concrete have been up to £50,000 per site.
