2.0 DETAILS
2.1 The scheme comprises:

· Taking up and relaying the existing kerbs to proposed levels.

3.0 FINANCIAL IMPLICATIONS & RECOMMENDATIONS
3.1 Seven conforming tenders have been submitted from the following Contractors from the Council’s Standing List:
1. RMC Surfacing
2. AE Yates Ltd
3. Tarmac Ltd
4. Aggregate Industries UK Ltd
5. Urban Vision
6. Westshield Ltd.
7. Bethell Construction Ltd.
3.2 The values of the tenders submitted are as follows: -
£580,238.63
£594,121.00
£645,784.48
£688,143.99
£699,347.98
£713,937.01
£771,120.88
3.3 The lowest conforming tender was submitted by Urban Vision in the sum of £580,238.63.
3.4 However, in accordance with the City Council’s Instructions for Tendering an additional alternative tender was submitted by Aggregate Industries UK Limited in the sum of £566,905.77. None of the remaining contractors chose to submit an alternative tender.
3.5 The alternative proposal is that:
· The hot rolled asphalt binder course as specified will be replaced with ‘Bardon Superflex’ binder course.
· Omit the geogrid asphalt reinforcement layer.
3.6 This tender has been checked and the alternative design investigated thoroughly and the potential advantages and disadvantages are detailed as follows: -
TABLE 1
Advantages
Item
/Discussion
1 / Laboratory tests results provided indicate that the material performs equally as the specified materials.2 / The material has been recommended by industry experts
3 / Omission of the geogrid will enable the material to be laid in the conventional manner reducing traffic disruption due to it being laid in a shorter period of time.
4 / Potential for shorter contract period hence reducing congestion.
5 / Omission of the geogrid will also reduce weakening/damage from future service trenches, over which the geogrid is not replaced.
6 / Reduction in the contract cost.
7 / The material has been used by other Local Authorities on major roads.
8 / Possible sustainable benefits due to reduction in materials used and improved durability.
TABLE 2
Disadvantages
Item
/Discussion
1 / ‘Bardon Superflex’ is a new product that has a limited history of its long term performance.2 / It has not been directly compared to a hot rolled asphalt reinforcement system.
3 / It is a proprietary product that does not yet have HAPAS certification (Industry Standard) guaranteeing long-term performance.
4 / Salford has no experience of using this product.
3.7 From the above, it can be seen that although there are many “advantages” to the alternative material there are also a number of “disadvantages” which increase the level of risk associated with using the product. However, notwithstanding these concerns it is believed that with the appropriate safeguards the potential risks can be minimised and consequently the alternative material should be used.
3.8 The financial implications are as follows: -
Works £566,905.77
Fees £38,516.00
TOTAL £605,421.77
3.9 The scheme will be funded from the Block 3 Transport Capital Programme 2005/06.
4.0 CONCLUSION
4.1 Resurfacing of the A5082 Cleggs Lane has been identified as necessary in the 2005/06 Block 3 Transport Capital Programme and this scheme will improve the condition of the Primary Route Network within Salford.
