03 - BID DOCUMENT ANALYSIS

OBJECTIVE

Carefully analyze the Bid Document and compare it with the Technical Specifications, drawings, contractual requirements, and any other available project information.

The purpose of this phase is to understand the project before beginning detailed cost development.

A complete review helps the estimator identify the real scope of work, required resources, contractual obligations, technical risks, and possible inconsistencies between documents.


KEY POINTS TO REVIEW

The analysis should consider, at minimum:

• Project scope.
• Construction sequence.
• Technical requirements.
• Contractual restrictions.
• Required resources.
• Special execution conditions.
• Site limitations.
• Access restrictions.
• Schedule requirements.
• Quality requirements.
• Testing and inspection requirements.
• Safety requirements.
• Temporary facilities.
• Owner-supplied materials or equipment.
• Contractor responsibilities.
• Subcontracted activities.
• Technical and commercial risks.


DOCUMENT COMPARISON

Do not review the Bid Document in isolation.

Compare it against:

• Technical Specifications.
• Drawings.
• Scope descriptions.
• Bill of Quantities.
• Addenda.
• Clarifications.
• Meeting minutes.
• Contract conditions.
• Owner requirements.
• Vendor information.
• Previous project references when applicable.

The objective is to detect differences, omissions, duplicated requirements, or conditions that may affect cost.


QUESTIONS THE ESTIMATOR SHOULD ANSWER

Before proceeding, the estimator should be able to answer:

• What exactly must be supplied and installed?
• What work is included and excluded?
• Who is responsible for each activity?
• What resources will probably be required?
• Are there special construction methods?
• Are there access, schedule, or operational restrictions?
• Are testing, commissioning, inspections, or certifications required?
• Are there temporary works or support activities?
• Are there specific brands, standards, or technical requirements?
• Are there activities that should be subcontracted?
• Are there risks that may require contingency?


WHY THIS IS IMPORTANT

Many estimating errors originate from an incomplete understanding of the bid documents.

A quantity may be correct but still produce an incorrect estimate if an important technical or contractual requirement was overlooked.

For example:

• Special access equipment may be required.
• Work may need to be performed during restricted hours.
• Materials may require special certification.
• Existing facilities may need protection.
• Equipment may require commissioning.
• Mobilization or transportation conditions may significantly affect cost.

These requirements may not always appear directly in the quantity list.


ORGANIZE THE BID STRUCTURE

After understanding the project, organize the Bid Document structure so it can be used efficiently in ZUCOST.

The items should be arranged in a logical order that reflects the project's sections, titles, groups, and executable items.

Verify that:

• Each item has a clear identification.
• Descriptions are understandable.
• Units are consistent.
• Quantities are available or identifiable.
• Titles and executable items can be distinguished.
• The order of the bid document is preserved whenever required.


IMPORTANT

Do not begin assigning resources before understanding the scope of the item.

The objective of this phase is not to calculate costs yet.

The objective is to understand what must be estimated.


RECOMMENDATION

Complete the Bid Document analysis before beginning detailed Matrix construction.

A few additional minutes spent understanding the project at this stage can prevent major corrections later in the estimating process.
