Carriageway resurfacing works

Tender description

Resurfacing of the Main Deck of the Tamar Bridge, including the north and south cantilever lanes. The successfully appointed contractor will also be required to manage the subcontract element of this project, which will involve liaising with the specialist manufacturer to safely remove the existing installed series of illuminated lane studs and being responsible for the timely installation of their replacements, as a key part of the overall resurfacing project. The work is anticipated to take place over a period of up to 9 months from the currently anticipated start date of 1.4.2020. The resurfacing overall is concerned with implementing Stage 2 of the current resurfacing strategy and follows on from the resurfacing Stage 1 of the Plymouth side span in 2011. The stage 1 works just replaced the worst section that had failed prematurely due to onerous loading conditions. Stage 2 of the resurfacing strategy, which includes the main deck centre span and the Saltash side span and north and south cantilever lanes, was based on a policy of lifetime maximization of the existing surfacing system until such a point when noticeable and problematic degradation commenced. At the time it was anticipated that the remaining areas would achieve their anticipated design life span in excess of 12 years and at the then anticipated levels of degradation was expected to last for another 3-7 years (2014-2018). It is now the point where the maximum life has been extracted from the remaining surfacing and replacement is required, commencing in spring 2020. Suitably experienced and qualified companies are invited to attend a supplier information event, to be held at the Tamar Bridge Offices, commencing from 10:00 a.m., on Thursday 5.9.2019, to find out more about the project and ask pertinent questions, before we look to formally advertise the opportunity in late September. If interested in attending this event, please confirm your intended attendance at this event by detailing your name, organisation name, job role and email address via the Portal messaging system for this project and initially we will be limiting participation to no more than 2 attendees per organisation. It is envisaged that the client will develop and enhance the agreed specification and scope of works, in collaboration with a likely maximum of 3 contractors, to be selected to discuss possibilities and options through a formal Competitive dialogue procurement process, to arrive at an optimum working solution for the most suitable surfacing application of the limited known options. Over an agreed period of time. It is intended to use the following objective criteria for selecting the limited number of candidates to take through to the competitive dialogue stage of the overall process based around clarity of their capability, availability and agreement on contractual preliminaries. More specifically an expectation that prospective contractors can meet or demonstrate the following mandatory requirements: 1) A successfully completed pre-qualification questionnaire including an expression of interest confirming willingness to participate in the proposed competitive dialogue process for its full duration; 2) Confirmation of suitability of previous experience to undertake such works and a clear understanding of health and safety and traffic management requirements; 3) Confirmation of availability of adequate resources to undertake the works commencing with design and planning in early 2020; 4) Contractor’s initial views on proposed form of contract, intended to be NEC3, tender period, liabilities and insurances to assist with achievement of a short but productive series of dialogue meetings, prior to tender submissions, tender assessment and governance approval periods prior to contract award.
