Technical requirements: Scottish Borders Council (the Council) intends to take forward a series of flood protection measures in Hawick town centre which will protect over 900 business and residential properties against the effects of the 1 in 75 year flood event in the River Teviot. The works will comprise around 6 km of flood defences walls and embankments, new culverts, surface water pumping stations, Hawick waste water treatment works pumping station, replacement of 3 footbridges and the provision of new landscaping and reinstatement of the riparian corridor. Further details of the proposals, including a list of organisations who have registered an interest in becoming part of the multi layered supply chain that will deliver this project can be found at www.hawickfloodscheme.com
The Hawick Flood Protection Scheme (HFPS) will provide a significant benefit to the residents and businesses of Hawick by virtue of alleviating the effects of a major flood event in the River Teviot. The town has suffered from flooding in the recent past, including large numbers of properties inundated in 2005 and 2015, causing significant economic and human adverse effects. The HFPS will comprise the construction of nearly 6 km of entirely new flood defences, the great majority of which are flood defence walls. The walls will generally be sheet pile cored to a depth of between 4 and 12 m below ground level, with reinforced concrete pile cap and stem. Exposed concrete will either be clad in natural stone or finished with a formlined pattern. Around 60 glass panels, each 2,5 m wide and up to 1,4 m deep are to be set into the floodwalls. Approximately 1,8 km of the defences will require to be constructed directly within the watercourse. A short section of embankment will comprise a sheet pile core with locally won granular shoulders. 8 entirely new automatic surface water pumping stations will provide further protection, comprising wet wells up to 6 m deep and 5 m diameter, valve chambers up to 4 m deep and 6 m diameter and GRP kiosks to house the power and control units. The MEICA design for the surface water pumping stations will be the main contractor design element. The discharge capacity of the submersible pumps will vary within each pumping station, with the largest requiring to deliver up to 450 l/s. A 9
Construction of the HFPS will be subject to a number of environmental and pedestrian/traffic management constraints, including restrictions on the time of year when works can be carried out within or adjacent to the river channel in order to reduce the impacts on salmon migration, and restrictions on which roads and footpaths can be closed simultaneously.
The Council are currently carrying out an advance works contract which comprises the diversion of a large number of existing public utilities and the felling of the majority of trees which may be impacted by construction of the project. This procurement exercise will still require the protection and small scale diversion of some public utilities and a small amount of tree felling.
The Council intend to appoint a main contractor to carry out the construction of this project under the terms and conditions of NEC3 (Engineering and Construction Contract) Option A contract.
Bidders must pass the minimum standards of the ESPD within Sections 4A, 4B and 4D of the PCS-t Qualification envelope.
Bidders must complete the scored element of the ESPD within Technical and Professional Ability at Section 4C which can be found in the PCS-t Technical envelope.
Section 4C will be scored as per the scoring methodology detailed below. Bidders must score 2 out of 4 (50 %) or above in each question of the technical envelope to be considered for short-listing to the Invitation to Tender (ITT) stage. Subject to passing this minimum standard the sum of the Section 4C weighted scores for each bidder will be used to create a final shortlist based on the minimum and maximum number of bidders to be invited to the ITT as stated above.
0 = 0 %: unacceptable, nil or inadequate response or fails to demonstrate previous experience/capacity/capability relevant to this criterion.
1 = 25 %: poor, response is partially relevant and poor. The response shows some elements of relevance to the criterion but contains insufficient/limited detail or explanation to demonstrate previous relevant experience/capacity or capability.
2 = 50 %: acceptable, response is relevant and acceptable. The response demonstrates broad previous experience, knowledge and skills/capacity/capability but may lack some aspects of similarity e.g. previous experience, knowledge or skills may not be of a similar nature.
3 = 75 %: good, response is relevant and good. The response is sufficiently detailed to demonstrate a good amount of experience,knowledge or skills/capacity/capability relevant to providing similar services to similar clients.
4 = 100 %: excellent, response is completely relevant and excellent overall. The response is comprehensive, unambiguous and demonstrates thorough experience,knowledge or skills/capacity/capability relevant to providing similar services to similar clients.
It is noted that the capability of bidders will be assessed on their previous experience of undertaking any major civil engineering project which has involved works in or adjacent to a river or coastal environment and which has been undertaken in or has had an impact on an adjacent or nearby major road.
