Tender Evaluations: Automate Construction Bid Comparison From Email

Construction bids rarely arrive in one consistent format. A procurement team may receive prices in email text, Excel schedules, PDF quotations, and supporting attachments. Descriptions differ between bidders, while currencies, payment terms, lead times, exclusions, and alternatives make direct comparison difficult.

Tender Evaluations turns incoming supplier and subcontractor emails into a structured bid-comparison workflow. AI extracts specifications, prices, terms, and exceptions, then normalizes them into a side-by-side matrix for commercial review.

The application reduces manual copying without transferring the award decision to software. Procurement and project leaders remain responsible for scope alignment, clarifications, risk assessment, and final approval.

Key takeaways

• Forward supplier bid emails to a controlled tender intake address.
• AI reads email text and attached Excel or PDF quotations.
• Items, currencies, payment terms, delivery dates, and exceptions are normalized.
• Weighted compliance scoring can compare more than the lowest price.
• Concolabs lists a USD $1,500 one-off setup and implementation fee for one large tender package.

What is Tender Evaluations?

Tender Evaluations is a Concolabs procurement product for contractors and construction procurement teams. It extracts bid information from incoming emails and supporting files, then creates a normalized comparison grid.

The system is designed for tendering and sourcing across the Middle East and Sri Lanka. Concolabs lists an implementation period of approximately one week and an email-intake deployment model.

Rather than asking every bidder to re-enter a quotation into a separate supplier portal, the product works with the communication method many trades already use: email. This reduces supplier friction while giving the buying team a consistent evaluation structure.

Why does construction bid evaluation take so long?

Bid evaluation begins with data preparation. Procurement staff download attachments, find the relevant rates, copy them into a spreadsheet, align item descriptions, convert currencies, and identify missing scope.

The work becomes harder when bidders structure quotations differently. One supplier may price a complete item while another separates labor, materials, delivery, and accessories. A low total may exclude work included elsewhere.

Commercial terms also affect the comparison. Payment conditions, validity, warranties, lead times, taxes, delivery terms, and proposed alternatives can change the evaluated cost and project risk.

Concolabs describes tender packages with more than 20 bids taking days to normalize manually. The product is intended to reduce this process to hours by automating extraction and alignment.

How does Tender Evaluations work?

The Tender Evaluations workflow uses email intake, AI parsing, normalization, and compliance analysis.

1. Forward incoming bids

Supplier and subcontractor quotation emails are forwarded to a custom tender intake address. The controlled address creates one collection point without requiring bidders to adopt a new portal.

The procurement team should define the tender package, closing rules, authorized mailbox users, and acceptable submission channels before bids arrive.

2. Extract rates, specifications, and terms

The AI parser reads information from email text and attachments. Concolabs states that the product supports free-text rates and complex Excel or PDF quotation files.

Extracted information can include item descriptions, prices, technical specifications, payment conditions, delivery information, warranties, and stated exclusions.

3. Normalize the bid information

Tender Evaluations pairs comparable items even when bidders use different descriptions or parameters. It places the results into a side-by-side matrix for review.

Normalization should never hide an assumption. If two items aren't genuinely equivalent, the matrix should identify the gap and require clarification.

4. Compare currencies and commercial terms

The multi-currency parser can convert bids using live conversion rates or project-defined limits. The system also compares lead times, payment terms, and warranty exceptions.

The evaluation should record the currency source, conversion date, rate, taxes, and any commercial adjustment. That preserves a clear basis for the comparison.

5. Score compliance and review the award position

The product can score bids against criteria beyond price. Weighted rules can consider delivery, payment, technical compliance, warranty, and other project requirements.

The output supports the award decision. It doesn't make that decision independently. Authorized stakeholders should review the normalized data, unresolved exceptions, and supplier capability before approval.

What information can Tender Evaluations extract?

Concolabs describes extraction from incoming emails, free-text quotations, spreadsheets, and multi-page PDF attachments. The comparison engine is intended to organize:

• Supplier or bidder identity
• Item descriptions and specifications
• Quantities, units, and rates
• Currency and tax information
• Payment terms
• Delivery dates and lead times
• Warranty terms and exceptions
• Exclusions and qualifications
• Alternative offers
• Compliance against tender requirements

Extraction should retain a link to the source email or attachment. Reviewers need to verify important values rather than relying on a detached summary.

How does side-by-side normalization improve bid comparison?

Normalization creates a common structure for quotations that were prepared differently. The aim is to compare the same scope, quantity, unit, and commercial basis across every bidder.

A useful comparison matrix should separate four types of information:

1. Directly comparable prices
2. Missing or excluded scope
3. Alternative technical proposals
4. Commercial qualifications and risks

Adjustments should be visible and traceable. If an allowance is added to one bidder for missing scope, the matrix should show the value, reason, and reviewer rather than silently changing the total.

The lowest submitted price and the lowest evaluated price may be different. A transparent matrix helps stakeholders understand why.

How does multi-currency tender evaluation work?

Tender Evaluations can read and convert currencies automatically. Concolabs states that the system can use live bank conversion rates or custom project limits.

Projects should define the conversion policy before bids are compared. The policy may specify a base currency, approved rate source, effective date, hedging assumption, permitted tolerance, and treatment of taxes.

Currency conversion is only one part of normalization. Reviewers should also assess payment timing, advance requirements, retention, validity, escalation clauses, and exposure to exchange movement.

The audit record should preserve both the original quoted amount and the normalized value. This prevents the comparison from losing the bidder's submitted commercial position.

Can bids be evaluated on more than price?

Yes. Concolabs describes compliance scoring that considers delivery dates, payment terms, and warranty exceptions. Weighted project rules can extend the comparison beyond the headline bid total.

A construction tender evaluation may consider:

• Technical compliance
• Scope completeness
• Evaluated price
• Delivery or program
• Payment conditions
• Warranty and defects obligations
• Supplier experience and capacity
• Safety and quality requirements
• Proposed alternatives
• Commercial exceptions

Weighting should be approved before evaluation begins. Changing the criteria after seeing prices can undermine fairness and governance.

What happens when suppliers quote alternatives?

Alternative offers should be separated from the compliant base bid. The evaluation can extract different options and place them into the comparison, but reviewers must decide whether each option satisfies the tender requirements.

Use distinct columns or scenarios for the base offer, approved alternatives, and non-compliant departures. Record the technical and commercial effect of each option.

An attractive alternative price may introduce design changes, approval requirements, program effects, maintenance implications, or warranty limitations. The decision should include the responsible technical reviewer, not only the procurement team.

How does Tender Evaluations compare with spreadsheets and supplier portals?

Manual spreadsheets offer flexibility, but they require repeated downloading, copying, matching, formula checking, and version management. Concolabs compares a one-to-two-day manual process with an automated result prepared in hours.

Supplier portals can structure information at source, but smaller subcontractors may resist creating accounts or retyping quotations into unfamiliar forms. Portals may also struggle with free-text offers and established supplier documents.

Tender Evaluations keeps email as the intake method and adds structured parsing after receipt. It aims to reduce friction for suppliers while improving consistency for evaluators.

Does Tender Evaluations choose the winning bidder?

No. The system extracts, normalizes, and scores bid data. The award decision remains with authorized project stakeholders.

Reviewers should still assess:

• Tender compliance and scope gaps
• Arithmetic and pricing assumptions
• Technical submissions and proposed alternatives
• Delivery and program commitments
• Supplier capacity and previous performance
• Payment terms, warranties, and exceptions
• Clarification responses
• Financial, safety, and quality risks
• Conflicts of interest and approval authority

The software should create a better evidence base for judgment, not replace procurement governance.

How should confidential bids be protected?

Tender information contains sensitive supplier prices, commercial terms, and procurement decisions. The product page describes audit logs and bid sandboxing as part of the automated approach.

The implementation should define restricted mailbox access, user permissions, bidder separation, audit records, retention, deletion, and approval rights. Shared comparison files should not expose one supplier's confidential data to another.

Buyers should confirm hosting, encryption, access controls, backup, incident response, and data-location requirements directly with Concolabs. The deployment must align with the tender rules and the organization's security policies.

What does Tender Evaluations cost?

As of August 2026, the Tender Evaluations product page lists USD $1,500 per tender. This is described as a one-off setup and implementation fee for one large-scale tender package.

Concolabs also offers an annual enterprise plan with custom volume licensing for developers and commercial main contractors. Buyers should confirm current pricing, tender volume, intake configuration, document support, user access, currency rules, scoring setup, and support terms.

The commercial case should consider evaluation time, transcription corrections, clarification effort, and the cost of missed exclusions—not only the setup fee.

How should a contractor pilot Tender Evaluations?

Choose a completed tender package with known bids, clarifications, and an approved evaluation report. Include different quotation formats, currencies, descriptions, exclusions, and alternatives.

Forward the original submissions into a controlled test intake. Compare extracted and normalized information with the approved manual evaluation at item level.

A useful pilot should measure:

1. Email and attachment ingestion success
2. Price, quantity, and unit extraction accuracy
3. Description-matching accuracy
4. Currency-conversion accuracy
5. Detection of terms, exclusions, and alternatives
6. Compliance-scoring consistency
7. Traceability to source documents
8. Time required for expert review
9. Permission and audit-log performance
10. Quality of the final comparison report

Acceptance criteria should prioritize missing or incorrect commercial information. A small percentage error can still be serious when it affects a high-value item or major exclusion.
