In the field of industrial workshop construction design, choosing the appropriate bidding method plays a crucial role in ensuring transparency, efficiency, and quality of the project. According to the 2013 Bidding Law, there are four main bidding methods, each with its own characteristics to suit different types of bidding packages. Let's explore them with BIC in this article!
This method is typically applied in the following cases:
- Bidding packages that fall under open bidding or limited bidding, primarily related to consulting services or small-scale procurement of chemicals and construction;
- Bidding packages that require competitive bidding, including non-consulting services, procurement of chemicals, and construction;
- Designated bidding packages, applicable to consulting services, non-consulting services, procurement of goods, and construction;
- Direct procurement bidding packages, usually applied to goods;
- Cases of selecting contractors through designated bidding.
Contractors participating will submit a single bidding document, which includes technical and financial aspects as required by the bidding invitation documents. The bid opening is conducted once, applying to the entire content of the bidding document.
This method is suitable for tenders that are more diverse in nature and is used in the following cases:
- Open or restricted bidding, applicable to consulting services, non-consulting services, procurement of goods, and construction;
- Open bidding for investor selection.
Bidders need to prepare two separate envelopes: one for the technical proposal and one for the financial proposal.
- First envelope opening: The technical envelope will be opened immediately after the bid closing time to evaluate the technical requirements.
- Second envelope opening: Only those bidders who fully meet the technical requirements will have their financial proposals opened for further evaluation, leading to the selection of the most suitable contractor.
This method is typically used for large, complex tenders or those with specific technical requirements, such as procurement of chemicals or large construction projects.
- Stage 1: Prepare the bidding documents with the main technical products and financial plan but excluding the bid price. This document will be evaluated and discussed with the bidders to identify necessary adjustments, thereby refining the documents for the next stage.
- Stage 2: Bidders who have passed Stage 1 will be invited to submit their official bidding documents. This includes technical proposals, financial proposals, bid prices, and bid security for price evaluation and selection.
This method is suitable for bidding packages that require high technical standards, modern technology, or are of a specialized nature, such as complex goods procurement and construction projects.
- Stage 1: Simultaneously prepare two envelopes, including the technical proposal and the financial proposal. After the bid closing time, only the technical documents will be opened for evaluation. Based on the evaluation results, technical requirements will be adjusted to finalize the bidding documents for Stage 2.
- Stage 2: Contractors who meet the technical requirements of Stage 1 will be invited to submit their complete bidding documents, including the bid price. The financial documents from Stage 1 will be opened along with the bidding documents for evaluation and selection of the most suitable contractor.
With the four methods above, the bidding process not only ensures transparency and fairness but also helps select capable contractors who best meet the requirements of each specific bidding package. Each method guarantees transparency, competitiveness, and economic efficiency, while also assisting investors in choosing the most suitable contractor. To ensure success in the bidding process, understanding and correctly applying regulations is a key factor contributing significantly to the success and sustainability of the project.
