Multi-element Analyses of Soil and Stream Sediment Samples by X-Ray Fluorescence Spectroscopy (XRFS)

 

 

 

()1.1.    Introduction

 

 

 

A regional geochemical survey of soils, stream sediments and stream waters in the border region of Ireland was recently completed by the Geological Survey of Ireland (GSI)[1]. Further stream sediment sampling at approximately 10,000 sites and soil sampling at approximately 10,000 sites will take place in the period 2016–2019.

 

 

 

This RFT is for geochemical analysis of these stream sediment and soil samples: (a) preparation of fine powder pulps into pressed powder pellets and (b) chemical analyses of the pressed powder pellets for major, minor and trace total element concentrations by X-ray fluorescence spectrometry (XRFS) analyses. Samples of milled sample material, each to be pre-prepared to pulps of nominal fraction size <32 μm, are to be transported from GSI in Dublin, Ireland, to the Contractor’s chosen facility to be prepared into pressed powder pellets designated for analyses by a combination of energy-dispersive (ED) and/or wavelength-dispersive (WD) XRFS chemical analytical methods. The number of samples to be collected in the period 2016–2019 is estimated to be of the order of 10,000 soil samples and 10,000 sediment samples. Collection of these samples is dependent upon successful completion of separate sampling contract(s).

 

 

 

Tenderers who propose alternative methodologies to those specified are reminded that the required specifications herein must form the basis of any proposed technical methodology. Alternative and superior technologies may be considered, and any deviation from the requirements set out here shall be evaluated against the Award Criteria.

 

 

 

Tenderers should note that only compliant and qualifying tenders shall be evaluated. The Qualification Criteria are set out in Part 3, Section 3.2 (pages labelled 16–20 of this RFT) and the Award Criteria, including minimum required scores, are set out in Part 3, Section 3.3 (pages labelled 20–23 of this RFT). Note also the Tenderers’ Statement (Appendix 3) and Tenderers’ Aide-Memoire (Appendix 5).

 

 

 

The absolute total number of samples is estimated and the final quantity will depend, inter alia, on sample collection by a third party under a separate contract and on sample preparation by a third party under a separate contract, and the availability of funding in 2017 and later years. It is estimated that 2,400 samples (±10%) will be available in late Autumn 2016. A single sample price is required in the pricing schedule. Some stream sediment samples are anticipated to be available for immediate collection and start of works upon award of contract. Time is not of the essence and the timing of sample availability is dependent on completion of the separate sampling contract.

 

 

 

Tenderers must respond with a proposal for the entire works.
