The tendering in construction is frequently perceived as the process where contractors provide prices, and the winner is declared the one who offered the lowest cost. However, this approach ignores a very important point: tendering starts with a project definition and the quality of the tender documents depends on the quality of the received bids.
Incomplete and poor-quality tender documents cause mistakes in pricing and misunderstanding and conflicts further down the road. Contractors cannot price something they do not understand, hence the gaps in documents cause the need for assumptions, which leads to problems later. On the contrary, a complete and accurate set of tender documents helps contractors to price the same scope of work the same way and compete fairly. According to the research findings, insufficient and inconsistent tender documents account for no less than 71 percent of the fundamental reasons of disputes in construction projects.
What Are Construction Documents and CD Sets?
The construction documents are the set of drawings, specifications, BOQs and other information which is used to communicate a project scope and requirements to all stakeholders. Construction documents are an intermediary step between building design and its construction, they are the tool which provides instructions how the solution should be implemented physically.
CD sets (construction document sets) are the complete set of drawings and specifications that sufficiently describe a project. Usually, they include architectural drawings, structural drawings, MEP drawings and the specifications which provide detailed descriptions of materials, installation, methods and quality standards of construction. Before the tendering process the CD sets should be checked and coordinated carefully to make sure that the documents provide full information about the scope and requirements.
Why Precise Documentation is Important Before Tendering
Precise documentation is the basic element that makes projects successful. If documents are precise and complete, they will improve scope definition and reduce the need for assumptions, which will help to price correctly. The contractors are able to estimate labor, materials and equipment needs properly when the scope is well defined.
The consequences of the poor quality of tender documentation may be significant and include the mistakes in cost estimation that leave the project over- or under-budgeted. They may cause delays because of submitting of requests for information (RFI) to clarify the ambiguities. Moreover, the documents' mistakes and gaps may cause variation claims later, as the contractors will try to get additional compensation for the work that was not included in the initial scope. The quality of technical specifications in tender documentation serves as an important mediating variable that influences the project performance in terms of time, cost and quality.
Improvements of Tender Outcomes Thanks to Accurate Documentation
Better documentation helps to receive more comparable bids. The use of precise documents helps the contractors to price equally, without the need to make assumptions about the scope of work and requirements. This makes the process of evaluation of bids much easier for the owners and consultants.
The use of accurate documentation also helps to increase the trust between project stakeholders. The contractors submit competitive and confident bids if the scope of work is well defined and they are not forced to price unknown work or to take some risks. This confidence often leads to the more accurate pricing, since there is no need to increase the bid in order to cover the risks.
Risks of Tendering With Deficient Documentation
The risks of starting the tendering process with the deficient documentation are significant:
Mispricing caused by missing details: If the drawings do not have dimensions, the specifications do not specify the material requirements or the BOQs are inaccurate, the contractors are not able to estimate the cost precisely. They must make assumptions or add the contingencies, inflating the price.
Scope gaps that lead to variation claims: The missing elements in the documents are variation claims later on, as everything that was not included in the scope should be done at an additional cost.
Delays due to RFIs and clarifications: All ambiguities in the documents generate RFIs that require time to be answered. It leads to delays in the procurement, scheduling and construction activities.
Rejection or poor quality bids: The bidders often submit non-compliant bids or reject participation in the process if the documents seem to them as unclear or incomplete.
Project disputes after the award: Probably, the most dangerous risk is the dispute in case contractors claim the misleading documents, while the owners are sure that the work was supposed to be done according to the tender documentation.
What Should a Good Tender Document Package Contain?
The good tender document package should contain the following elements:
Drawings: the complete and coordinated architectural, structural and MEP drawings with all dimensions, locations and relationships of the building elements.
Specifications: the written description of the materials, installation methods, quality standards and performance requirements mentioned in the drawings. Specifications and drawings should complement each other, neither of them should take the precedence over the other.
Bill of Quantities (BOQ): the quantified list of work items that is used by contractors to price their work. The BOQ should correspond to the drawings and specifications.
Scope of work: the definition of what is included and excluded from the contract and defines the contractor's responsibility.
Contract conditions: the proposed contractual terms, including the payment conditions, delivery timelines, warranties and the procedure for resolving disputes.
Any additional information that helps the bidders to understand project requirements and limitations. Instructions on how the bids should be prepared and the deadlines. All bidders should work with the same information and the complete package will help them to compare their bids fairly.
Role of Professional Construction Documentation Services
Professional construction documentation services are useful for the developers, architects, contractors and consultants who require precise and coordinated tender packages. Such services help to improve the consistency of documentation and increase its quality and efficiency for the bid stage.
The use of the third-party document review may be especially helpful. According to the research findings, the independent review of tender documentation before its usage for contractor selection helps to identify the mistakes and deficiencies that are not detected by the internal team.
Modern documentation services usually use the technological solutions, such as BIM, to generate the coordinated and clash-free model and reduce the possibility of errors and misunderstandings among the stakeholders. Modern technologies provide 3D visualization of the projects.
Benefits of Accurate Documentation for Contractors and Clients
For clients
Precise documentation helps to receive more reliable pricing because the contractors are able to price bids based on complete information and not on assumptions. It reduces disputes because the ambiguities are eliminated and helps to compare bids better, making the evaluation process objective and efficient. Finally, it allows smooth project implementation, as the construction team does not have to look for clarifications and unexpected scope gaps.
For contractors
Clear scope definition helps contractors to estimate work accurately, reducing the probability of under- or overbidding. Better estimation allows increasing profitability, as the contractors will price work accurately and without excess contingencies. It also reduces the risk as the scope of work is well-defined and the contractors are not responsible for the work that is not specified in the documents. The contractors are able to submit confident bids working with the precise documents.
This correlation between the quality of the documentation and commercial and operational success is very significant. The quality of technical specifications serves as an important mediating variable influencing the project success in terms of the Iron Triangle of time, cost and quality.
Best Practices to Ensure Documentation Accuracy
Several recommendations can help to ensure the accuracy of the documents before tendering:
Coordinate the drawings and specifications before issuing tender sets: Make sure that what is shown in the drawings is reflected in the specifications and vice versa. The discrepancies between the documents cause misunderstandings and claims.
Check for missing dimensions, inconsistencies and outdated revisions: All missing information, inconsistencies and outdated documents that are not revised should be found during the thorough check.
Make sure that BOQs are up-to-date and correspond to the current design intent: The BOQ should match the drawings and specifications. Discrepancies between the BOQ and the design documents cause mistakes in the pricing.
Perform peer review or third-party check of the documents: The independent review by the professional that was not involved in the documents' preparation can help to find mistakes that internal team could not see. The verification process that checks the factual correctness and absence of omissions can be very effective.
Establish the tender clarification process: Define the formal process of asking questions and receiving clarifications from the contractors during the tender period.
Accuracy in Tendering Documents is the Key to Success
Accurate construction documents in tendering are not only formality but also a valuable advantage. Proper preparation of documentation prior to tendering will protect budgets and reduce the risks of failure of the bidding process. The quality of documentation will determine the quality of bids received by the owner and create an atmosphere of transparency for the whole construction process.
With accurate and proper documentation, owners will get precise and reliable prices and smooth project execution. Contractors will be able to bid successfully and earn money on the project. There will be no disputes, and the success of the project will become more predictable. Accuracy in construction documentation is necessary for success in such a risky business as construction.
