## Tendering & Bill of Quantities
- Overview of fundamentals, process stages, and measurement logic in construction projects.

## What is a Tender?
- Definition: A formal competition where an authority announces a project.
- Goal: Select proposals based on scope, cost, and quality.
- Distinction: 'Tender' is the document; 'Tendering' is the process.

## Stages of Project Tendering
- **Inception:** Economic analysis and feasibility study.
- **Tender Stage:** Design and BoQ preparation.
- **Pre-Contract:** Technical and financial evaluation.
- **Contract & Execute:** Signing and monitoring.

## Types of Tenders
- **Open:** Publicly announced to all.
- **Selective:** Invitation only (usually around 3 companies).
- **Negotiated:** Direct discussion; higher risk.
- **Staged:** Shortlisting technical proposals before financial review.

## The Submission Process
- Includes pre-bid meetings and site visits.
- **Two-Envelope System:** Technical proposals (experience/qualifications) are opened first; financial proposals (pricing) are opened only if technical criteria are met.

## What is the Bill of Quantities (BoQ)?
- Translates engineering drawings into measurable items.
- Purpose: Scope definition, standardization for price comparison, and organization.

## Structure of the BoQ
- Standard columns: Item No., Description, Unit, Quantity, Rate (Price), and Total Amount.
- Example: Masonry walls (10cm thick), 150 m² at $20/unit = $3,000.

## Measurement & Contingency
- Works are categorized (Civils, Masonry, Woodwork).
- A Contingency Allowance (usually ~10%) is added for unforeseen issues.

## Transparency & Local Context
- Discussion on ideal transparent processes versus regional variations (e.g., Palestine).
- Role of the Quantity Surveyor (QS) in global vs. local contexts.

## Real-Life Example: Beit Surik Art Center
- Case study of a design services tender including design, licensing, restoration, and finishing.
