2 Contractor’s Pricing for Preliminaries - Overview
1. There is no hard and fast rules to price preliminaries. 2. The purpose of this seminar is to cover the basic principles of building up cost and eventually pricing for preliminaries. 3. The speaker will share his experience in pricing preliminaries for submitting tenders of building projects. 4. A Sample Case will be discussed for compiling the preliminaries cost (not exhaustive) of a sample building project.

3 Method of Pricing Preliminaries
1. To allow % mark-up (based on similar previous projects) on the estimated cost of the project. 2. Build up the cost of preliminaries items (with significant cost implication not covered in BQ/SOR) in detail.

4 Factors to be Considered When Pricing Preliminaries
Standard preliminaries items (See Sample Case) Contract requirements Statutory requirements Payment method for preliminaries items Maximum % of preliminaries stated in the tender documents Type of Contract (Lump sum with or w/o quantities) Contract period (and actual construction period) Amount of LD (and EOT clause) Reputation of the Employer and Consultants Mode of Sub-contracting Location of the Site Ground condition Market condition Contractor’s resources, financial capability and workload Contractor’s pricing strategy

5 Prices to be Included in Preliminaries or BQ/SOR
Prices for some items that may be included or absorbed in BQ/SOR. Examples: - 1. Items Included in BQ/SOR ● Hoarding ● ELS works ● Some testing items (e.g. water test for waterproofing and windows & performance test for curtain walls, etc.) ● Safety management ● Attendance on NSC works 2. Contractor’s Pricing Practice ● Mobile crane (included in the rates of structural steel works) ● Scaffolding (included in the rates of ceiling works) ● Wet cleaning (included in the rates of tiling works)
