Section II: Object of the contract

LUL are therefore looking to develop an Escalator Control System procurement strategy for the fleet of escalators for which they are responsible. The development of the strategy covers:
(a) the replacement and subsequent maintenance of approx 33 Escalator Control Systems for escalator sizes ranging between 11 m and 28 m vertical rise. It is scheduled to replace these systems from May 2014 to end of 2017.
(b) the maintenance of approx 187 existing Escalator Control Systems.
To assist in the development of a new strategy for Escalator Control Systems, LUL are looking to have a Technical Dialogue with interested parties to assist in the understanding of their ability to supply and maintain systems that are compatible with heavy traffic volume operations and be compliant with LUL procedures, and other relevant standards.
The technical dialogue will involve:
1) Reviewing and assessing the effect of any differences between LUL’s specifications (for both supply & installation and maintenance) and the suppliers’ proposed solutions.
2) Understanding what (if any) elements of LUL’s operational and assurance requirements would require a specialised approach from suppliers.
3) Receiving suppliers’ views and ability to provide Escalator Control Systems compliant with reference to LUL’s EMC environment.
4) Receiving suppliers’ views and ability to provide Escalator Control Systems compliant with reference to LUL fire performance requirements.
5) Receiving and assessing suppliers’ role and interest in maintenance of the systems (replaced and existing), and its extent in respect of scope of maintenance, minimum volume and duration.
The replacement of Escalator Control Systems may involve, but not be limited to, the provision of the following components and elements for a particular escalator being refurbished:
— New AC motor, coupling and adaptor bedplate.
Note: The existing reduction gearbox, drive sprocket and mechanical operational brake will be retained.
— New ‘Castell’ key (or equivalent) interlocked fused isolator assembly, providing independent, escalator specific, safe means of isolation.
Note: The existing incoming power supply arrangement will be retained. A busbar with local isolation (or equivalent) will be required where a single incoming power supply feeds more than one escalator.
— New VVVF drive and control system with facility to transfer status and alarm data through Industrial Ethernet to a remote panel.
Note: The VVVF drive shall be of the Active Front End type, in order to limit the harmonics drawn from the supply.
— New Field wiring and peripheral switches, safety devices and associated mechanical assemblies.
LUL are looking for suppliers to confirm interest in providing the following:
(a) Design, supply and installation.
(b) One or two years maintenance of replacement of Escalator Control Systems, after which it then devolves to another maintainer.
(c) Maintenance for full life of the replaced Escalator Control Systems.
(d) Maintenance of the existing Escalator Control Systems.
(e) Combination of the above.
In addition, LUL are interested in your comments on the following:
(a) the minimum / maximum number of replacement of Escalator Control systems per annum / duration
(b) scope of maintenance
— Planned Preventative Routine maintenance.
— Emergency call-out with an hour response time (1st line response).
— Fault Fix response (2nd line response).
It is the purpose of this Technical Dialogue to provide LUL with information on what is currently available in the market place, thus enabling decisions to be taken to ensure the new LUL strategy is further developed in the full knowledge of what the participating suppliers have to offer while still meeting the needs of LUL.
It is expected that LUL will initiate a competitive process fairly soon after it has completed the strategy review so that LUL can relatively quickly gain suppliers’ product experience and commence in-service performance review of individual designs.
If suppliers express an interest in participating in the Technical Dialogue then they will be sent a Project Briefing Document, outlining in further detail the questions that LUL are posing. The deadline for receipt of completed responses is 12:00 noon on 8.5.2013
It is anticipated that interested parties will initially submit a written response, although there may be some areas of clarification required. LUL may then request a presentation from interested parties at which point further questions can be tabled by both interested parties and LUL.
Whilst LUL do not wish to ask for any sensitive or proprietary information associated with suppliers’ equipment, any information supplied of a commercially/technically sensitive nature will be treated in the strictest confidence.
It is hoped that interested parties will assist LUL to formulate its new Escalator Control Systems strategy and subsequently be able to participate in the various competitive processes for the requirements that fall under the control or guidance of LUL.
This is not a stage in a formal competitive process and it should be stated that not participating in this Technical Dialogue will not restrict interested parties’ ability to participate in any future competitive process run by LUL for new Escalator Control System purchases. It is probable that LUL will use CompeteFor to advise smaller companies of our intent.
Any dialogue that has already taken place, outside of this Notice, will be considered as a partial submission, until confirmed as fully responded by those suppliers.
The outline timings for these processes are as follows:
Responses received to Notice 28.3.2013.
Project Briefing Document issued 3.4.2013.
Project Briefing Document returned 8.5.2013.
Complete clarification and presentations 28.5.2013.
Once the Technical Dialogue process is complete LUL will look to quickly finalise its future requirements to decide what competitive processes it will adopt to feed into upcoming competitive processes in 2013 and beyond.
