Analysis, Claims, Disputes, Resolution)
The Protocol (Structure)
The Protocol (Aims and Achievements)
Challenges in Implementing the Protocol
-
7/29/2019 Challenges Protocol
3/96
Contracts and Project Delays
Contracts have completion dates and liquidated
damages are tied to completion date
Extension of Time clauses maintain LD provisions
where there has been breach by Employer
If Employer causes a delay and there is no EOT
clause, time can (not universal) become at largeand LD clause fails.
EOTs also relate to financial matters including
bonus situation
-
7/29/2019 Challenges Protocol
4/96
Contracts and Project Delays
Contract provisions define the basis of entitlement
Contracts are imprecise as to how to demonstrate
delay and prove entitlement
Debate about actual delay and contractual
entitlement
Hence Delay Analysis Methodology has
developed
SCL Protocol advances Delay Analysis
Delay to be on the critical path

Extension of Time Methods
Estimate or Model Methods (investigate the EVENT
and its potential impact)
Actual Methods (identify the DELAYperiodand
investigate what caused it)

Prospective and Retrospective
Approaches P looks forward and anticipates delay
(Preventative; forward looking)
R looks back and establishes cause ofdelay (Curative; allocation of blame)
SCL Protocol offers another approach to
R; put yourself back at the time of theevent and re-assess what might have
happened had things been done
differently.

CORE PRINCIPLES
Good Programme Systems and Management
Good Record Systems and Management
Contemporaneous, incremental, assessment of delays and
award of Extensions of Time
Time Impact Analysis is the preferred methodology
Float Project owns, Contractor receives compensation
Concurrency Contractor receives Time but no Money
Retrospective delay analysis Re-live the Project; contradicts
usual assessment of damage?

Extensions of Time after the Project (Retrospective)
Four Methods
Updated/Revised Programmes Balance taken re time/costs
Consider the terms of the Contract
Factual analysis or Entitlement driven?
Placing oneself back at the time of the delay
-
7/29/2019 Challenges Protocol
70/96
THE PROTOCOL
-AIMS-
Not intended as a contract document
Offers specification terms for programme
management and record keeping
Offers guidance in the management of delay and
disruption that is, in the management of change
Extensions of Time should be dealt with at the time Time Impact Analysis is the recommended method
-
7/29/2019 Challenges Protocol
71/96
THE PROTOCOL
-ACHIEVEMENTS-
Hoped that Contracting Parties would adopt its
recommendations Prospective X
Hoped/Attempted to have industry contractingbodies adopt it Prospective X
Attempted to have the Courts adopt it
Retrospective X Delay Analysts adopt it
Added to knowledge; Great Debate!
-
7/29/2019 Challenges Protocol
72/96
THE PROTOCOL
-CHALLENGES-
Must be Industry/Profession/Employer led
Main Contractors would be unwise adopting it with
Subcontractors
It reduces risk pre-set rules/outcomes
It increases riskassumes one solution for all cases
Early delays tend to over-compensate the Contractor
Protocol needs re-drafting to remove optional aspects
-
7/29/2019 Challenges Protocol
73/96
THE PROTOCOL
-CHALLENGES-
Needs to deal more practically with constructive acceleration
Should advance a debate on the fairness of condition
precedent clauses
Does it amend the basis upon which damage is normally
assessed?
English law focussed; need to consider other legal systems.
-
7/29/2019 Challenges Protocol
74/96
THE PROTOCOL
-CONCLUSIONS-
Drafting requirements
Commercial implications; risk issue
Methodology greatly influences outcomes
Practical implications; skills and resources
required
Not widely adopted yet on live projects
Authors to be complemented for creating
Great Debate
