WLC Material Coring and Testing Framework Agreement

Overview

Lots (4)

• Sampling and Testing of Civil Engineering Construction Materials

  Award of Lot which will primarily encompass the sampling, testing and analysis of a variety of road construction materials including, but not limited to, the following: - Unbound stone/aggregate materials; - bituminous pavement materials including surface dressing; - bituminous pavement characteristics (e.g. skid resistance, texture depth, surface regularity); - fresh concrete materials and kerbs; - soils/sub-base/formation materials to determine ground conditions (e.g. grading, moisture content, shear strength, density, compaction, CBR testing etc). It is expected that the bidding laboratory will have a current UKAS accreditation but bids from non-UKAS accredited labs may be considered if they can demonstrate they have adequate quality management systems in place.. Re: SPD Q3D.1, 3D.2 and 3D.3 Bidders should answer these questions on Environmental, social and labour law in relation to compliance with the regulations covering Scotland and the UK.

• Coring and testing to determine Coal Tar Content in bituminous pavements

  Award of lot which will cover the sampling and testing of bituminous road pavement materials (generally by extracted road pavement core) to determine if coal tar is present within the layers of the road pavement. The procedure will include for an initial test (generally using the PAK marker paint method) to determine the presence of coal tar and, if coal tar is indicated, laboratory analysis to determine and confirm if coal tar is present and, if so, the amount of coal tar present. The principal testing objective is to determine: - if coal tar is present in the samples; - that coal tar indications are not ‘false positive’ indications caused by contaminants such as diesel, kerosene, petroleum-based materials etc; - when coal tar is found, the concentration levels of Benzo[a]pyrene and coal tar expressed as both a percentage and mg/kg. We will, in general, be following “The Transport Scotland Guidance Note: ‘Dealing with coal tar bound arisings” for the methods of coal tar sampling, sample preparation, testing and reporting of results. Bidding laboratories will be expected to work in accordance with that guidance note and our own specific requirements. Further detail is provided under the Schedule of Tests, Clause 3. The Guidance Note requires that the laboratory involved in the sample preparation and testing must be UKAS accredited as a minimum..

• Investigation of concrete structures

  Award of Lot which is primarily targeted at the testing of existing concrete structural assets such as road bridges and underpasses. The work will include the sampling and analysis of hardened concrete and structural paint coatings and will include a range of (mostly non-destructive) tests. The tests will include, but not be limited to the following: - The determination of chloride content, sulfate content, depth of carbonation and the cement and aggregate content of hardened concrete. - Cover meter survey (to locate reinforcement in a structure and measure the depth to the reinforcement from the concrete surface). - Half-cell potentiometer testing (to determine condition and corrosion of reinforcement in hardened concrete). - Schmidt/Rebound spring driven hammer survey (to measure surface hardness of concrete as a means of estimating the concrete strength). - Petrographic sampling, testing and analysis of concrete (to determine mineralogical and chemical characteristics and to determine whether the aggregates therein are susceptible to Alkali Silica Reaction). Also required will be the sampling and testing of structural coatings including paint sampling and analysis for lead content, paint thickness testing and paint adhesion/pull off testing.. Re: SPD Q3D.1, 3D.2 and 3D.3 Bidders should answer these questions on Environmental, social and labour law in relation to compliance with the regulations covering Scotland and the UK.

• Site Investigation

  Award of lot which will encompass a small range of site investigation services, that will include, but not be limited to: - Trial pits to determine ground conditions, material layers, and for material sampling in both superficial deposits/soils and in bituminous pavements. - Extraction of soil samples using hand auger techniques. - Ground Penetrating Radar survey to identify changes in ground conditions and voids. All services to include for the technical reporting of findings with all reports and test certificates to be provided to the Client within 3 weeks of testing..
