The document outlines the construction tender process between clients, contractors, and subcontractors. It discusses the various stages a contractor goes through when submitting a tender, including reviewing project details, conducting site surveys, developing cost estimates and bills of quantities, considering available resources and equipment, and ultimately submitting a bid package. The tender process depends on the type of tender (open or selective) and involves the contractor strategically planning and scrutinizing all available tender documents.

Each stage has a systematic set of interfaced proceedings,

3. Clients Tender Invite – Process
Instruction/Invitation to Tender sent to contractor (need to
identify which tender approach as they are different)
Contractor receives the request for bids (open or selective)
Tender Assessment by Contractor (strategic board review,
dependant on size of project and tender type)
De-briefing of tenderers (scrutinise)
Client issue Letter of Intent (may be optional, depending on tender
type, selective or open)
Award Construction Contract
Project, Goods and/or Services delivered (depending on contract to
be used; (lump sum, cost reimbursement, etc)
Project Payment and statutory document realized
Project Closure
4. Invites contractors (open or select contractor) to submit
the price for which they are willing to carry out a project
(e.g., business, technical, economical, management)
Typically depends on type of competitive, open or selective
tender; contractor relies on level of information contained in
tender, pre-lim drawings, specifications , bills of quantities
prepared on behalf of the client (e.g., architects, consultants).
Tender type (dictates the level of design, cost and construction)
Open (anyone, may include 2 stage pre-qualification )
Selective (usually have worked with the client)
One or two stages, closed (combination)
Client Tender - Invite Contractor
5. Client advertises openly in press or trade publications inviting
contractors to apply for the project
Contractor that is able to under take the project would request a
tender document (depending of type of tender)
After receiving the tender (open or selective) from the client (e.g.,
clients architect, design team, procurement department),
contractor may need to give deposit to ensure a bona fide tender.
Filter out the contractors who are not interested in submitting a
tender.
Open tender is sent to contractor, treated as offer to do work for
assured sum of money, generally preceded by a prequalification
document and statement of works, lists, requests, etc.
Clients Process - Approach
6. 1) Introduction to Tender (purpose reviewed at board level to attain
decision)
2) Project background (scope , location, size), quantity Survey
3) Legal issues (type of contract), Tender scrutiny
4) Maintaining issues (acceptance criteria)
5) Contractor / Supplier response required (contract period; topically
90 days)
6) Timetable for choosing contractor / supplier (program, planning &
scheduling)
7) Requirements (standards, specifications, IT, resources)
8) Preliminary Designs (basic schematics for taking off)
9) Bill of Quantities (high level quantities and measurements)
10) Miscellaneous: Other Issues (risk, quality H&S, performance,
control, etc)
Typical Tender Process - Contractor
7. It is assumed that the contractor possesses the in-
house capacity to carry out for example; all designs,
bills of quantities, topological, geographical and site
surveys , sewerage and drainage (utilities).
The contracting company possesses the equipment
necessary to carry out basic tasks with its own
specialized equipment such as haulage, cranes, JCB’s
and scaffolding.
Making Assumptions
8. Contractors Process – High-Level
Typically starts with contractor reviewing / planning tender
(systematic scrutiny of tender documents)
Typically involves site survey to establish project scope,
type, location, geotecs, cost estimate and quantity take offs
Planning Tender & Building Site Survey (contractor)
Bill of Quantity:
materials,
resources (technical abilities)
Equipment (plant – tools)
Labour
9. Construction Tender - Road Example
Contractor / trade contractor collects information needed to
work out the tender bid, and then complete the bid.
Completion of the bid takes place primarily by filling in bid
schedules and drawing up a covering letter to the client.
