Description

The Regional Water Supply St. Gallen (RWSG) is currently constructing the new Riet II lakewater plant. As part of this project, the municipality of Goldach has the opportunity to make use of the new lake water intake and thereby establish a thermal network providing. Using large-scale heat pumps, lake water can be utilized as a renewable energy source to provide environmentally friendly heating for households, public buildings and commercial premises.

The project is divided into two sub-projects:

Sub-project 1 – Energy Centre

Sub-project 2 – Distribution Network

The contract covers SIA sub-phases 32 (construction project) to 53 (commissioning) for sub-project 1 – Energy Centre.

The general planner’s mandate comprises the following services and specialist areas:

- Overall management and coordination of specialist areas (including construction management)

- Chief site management

- BIM management

- Civil engineering, including specialised civil engineering

- Building construction/structural engineering

- Piping (heating/cooling), including building connections

- Architecture

- Landscape architecture

- Fire protection

- Plant engineering

- HVAC

- Electrical and low-voltage systems

- Building automation

- Building physics

- Geology

Suitability criteria

  1. EK 1 Technical capability in the tendered disciplines (company references)

    A corresponding reference from the tenderer must be submitted for each suitability criterion (EK 1.1 to EK 1.5). Several suitability criteria can be demonstrated by a single project, provided that the respective requirements are clearly evident. Alternatively, separate reference projects can be submitted for individual suitability criteria. The submitted company references must demonstrate services comparable to the tendered project in terms of task, state of the art and complexity, and must mandatorily fulfill the requirements listed below: EK1.1 Overall management / overall coordination (incl. construction management) - SIA partial phases 32-53 - Project completion within the last 10 years - Total construction costs > CHF 3 million EK1.2 Civil engineering - SIA partial phases 32-53 - Project completion within the last 10 years EK1.3 Building construction / structural engineering - SIA partial phases 32-53 - Project completion within the last 10 years - Construction costs in the discipline > CHF 2 million - Volume > 3000 m³ EK1.4 Plant engineering - SIA partial phases 32-53 - Project completion within the last 10 years - New construction of a heat pump with a thermal output of more than 2 MW and a natural refrigerant - Boiler with a thermal output of more than 5 MW EK1.5 Geology - SIA partial phases 32-53 - Project completion within the last 10 years For areas EK1.1-EK1.5, it is expected that SIA partial phases 32 to 53 are completed or have been realized in essential parts. If these requirements cannot be met by a single reference project, two references may be submitted which together cover all requested phases. The company references for EK1.2 - EK1.5 may come from a sub-planner. In this case, the tenderer must enclose a confirmation from the sub-planner stating that they will execute the work if awarded the contract.

  2. EK 2 Appropriate ratio of contract amount per year to the turnover of the relevant corporate unit (i.e. relevant division according to the present project) per year (max. 30%)

    The average annual fee for this contract must not exceed 30% of the average annual turnover of the corporate unit or division responsible for the project. The calculation is made for all tenderers on the same basis: Annual fee: Total offered fee including incidental costs and minus discount, excl. VAT, divided by three. Average annual turnover: Sum of turnovers for the years 2023, 2024 and 2025, excl. VAT, divided by three. The annual turnovers must be stated in document C. In the case of planner consortia, the turnovers of the participating corporate units are added together for each year. The three years form the fixed calculation basis for this suitability assessment.

  3. EK 3 Sufficient proficiency in the BIM methodology

    1 project reference demonstrating experience with the BIM methodology in a comparable task. The project reference must have completed SIA phase 3. If the required reference comes from a sub-planner, the tenderer must enclose a confirmation from the sub-planner that they will execute the work if awarded the contract. The BIM platform is to be provided by the tenderer. The specification of the selected BIM platform must be enclosed with the bid and the details in document C2 must be filled out.

  4. EK 4 Organizational and financial capability

    Signed self-declaration C1.

Award criteria

  1. ZK 1 Price · Weighting 30 %

    Total fee and incidental costs incl. discount; the lowest bid receives the maximum grade; bids that are 100% or more above the lowest price receive 0 points; scoring between is linear

  2. ZK 2 Order and project analysis · Weighting 30 %

    Project challenges and opportunities; Presentation of the 5 most significant project-specific challenges as well as possible measures to manage them, and the 2 biggest opportunities including their impact on the project (max. 1 DIN A4 page) (10%). Procedural planning and organization: Presentation of the planned procedure, schedule risks and possible measures to mitigate them, as well as the planned organization including expected interfaces and BIM (max. 1 DIN A4 page + schedule + organization chart) (10%). Measures to promote sustainability and circular economy: Identification of the most important ecological aspects in the project and presentation of innovative measures for their implementation (max. 1 A4 page) (10%).

  3. ZK 3 Competence of key personnel · Weighting 30 %

    Information on the education and professional experience of the designated key personnel: 1 project reference with comparable complexity and task of the key person involved in the project. The specified references should essentially demonstrate the function, the main focus of tasks and the experience gained. The (partial) phases processed by the key person and specified as a reference must be completed. If the required references come from a sub-planner, the tenderer must enclose a confirmation from the sub-planner that they will execute the work if awarded the contract. German language skills (native language or at least language competence level C1) References must be provided for the following key personnel: Overall management / coordination Plant engineering specialist Chief site manager

  4. ZK 4 Presentation · Weighting 10 %

    With the designated key personnel, the tenderers present their order and project analysis. They also explain their reference projects and answer open questions from the client. If, after the evaluation of the submitted bids, there is no prospect of an award for tenderers, the awarding authority reserves the right not to invite these tenderers to the presentations. There is therefore no entitlement to a bid presentation.
