Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Can a COntractor hold on to the approved logic of a project schedule as one of its contractual rights?

The logic I am referring is the proposed sequencing of work of a certain project, which have been approved by the project consultant. During the course of evaluation for Time Extension, the approved logic was deemed illogical with respect to predecessors and successors of some activities. For example, the logic presented that plastering works cannot start unless the installation of air-conditioning units is completed. In which case, if the duration for installation of air-con is increased due to increase in qty (or it started late due to factors attributable to the owner), the start of plastering works will automatically move forward contributing to longer than expected extension of time. The Consultant would not agree using the same logic of schedule that was previously approved and suggested to re-arrange the logic to make it appear more logical.

The Contractor initially insisted on its Contractual right to use the original logic because it passed the required processing for approval. During the negotiation, the COntractor conceded to re-arrange the schedule if only to preserve its good relationship with the consultant and owner. Hence a shorter extension of time was achieved. This however corresponds to reduce time extension claim on the part of COntractor.

I am just curious whether the COntractor has valid claim assuming it will push on his initial claim for contractual right to use the original logic of approved schedule.

Hi Caline

This is an interesting case and no doubt those who have to provide learned judgement will have to take the specific aspects of each matter into account.

However, to add my mere opinion, I do not think it is sensible for logic errors that may have been made in the initial compilation and/or approval of a baseline programme to be perpetuated ad infinitum. I find it bizarre that a decision would be made in such a way when, to award damages (or the equivalent extension of time in this case) there has to be a causal link demonstrated between the event and the delay to the project. Where there is an error in the programme the causal link may also be eroneous.

In the UK the Society of Construction Law Delay and Disruption Protocol attempts to give some guidance on this matter (SCL Delay & Disruption). Section 2 is ‘Guidelines on preparing and maintaining programmes and records’

2.2.1.4 … Acceptance by the CA merely constitutes an acknowledgement by the CA that the Accepted Programme represents a compliant, realistic and achievable depiction of the Contractor’s intended sequence and timing of construction works. Acceptance does not turn the Contractor’s programme into a contract document, or mandate that the works should be constructed exactly as set out bin the Accepted Programme … Disagreements over what constitutes the Accepted Programme should be resolved straight away and not allowed to continue through the project. …

2.2.1.5 The contract should require that the Accepted Programme be updated with actual progress using the agreed project planning software and saved electronically at intervals of no longer than one month … The purpose of saving monthly versions of the programme is to provide good contemporaneous evidence of what happened on the project, in case of dispute.

2.2.2 The Accepted Programme (which then becomes the Updated Programme) should be the means by which actual against planned progress is monitored and (as will be seen later) can be used as a tool for determining EOT. …

2.2.3 The Contractor may wish to change or develop the Accepted or Updated Programme, either to expand or develop the detail of activities that it had not fully planned at the time of acceptance of the programme or (where necessary) to change the logic or sequence of activities. …

2.2.4 Actual construction and the Contractor’s current intentions should always be reflected in the most recently submitted copy of the programme. …

Keith Picavance cites an unreported case (Delay and Disruption in Construction Contracts – second edition. Keith Pickavance. LPP Reference Publishing (2000), p 416.):

the Arbitrator held that ‘… the approach of (the expert for C) in correcting inconsistencies, illogicalities and adding logic to the programme to produce the base-line from which to deduce the impacts is the proper procedure to adopt…’.

As for whether Contractors actual progress should be taken into account when assessing delays the SCL Protocol says at paragraph 4.8

Time impact analysis is based on the effect of Delay Events on the Contractor’s intentions for the future conduct of the work in the light of progress actually achieved at the time of the Delay Event and can also be used to assist in resolving more complex delay scenarios involving concurrent delays, acceleration and disruption. It is also the best technique for determining the amount of EOT that a Contractor should have been granted at the time an Employer Risk Event occurred. In this situation, the amount of EOT may not precisely reflect the actual delay suffered by the Contractor. That does not mean that time impact analysis generates hypothetical results – it generates results showing entitlement. This technique is the preferred technique to resolve complex disputes related to delay and compensation for that delay.

Details of Time Impact Analysis can be found in my paper ‘A methodology for assessing construction project delays’ (David W Bordoli & Andrew N Baldwin. Construction Management and Economics (1998) 16, 327-337)

Ok Caline ,
Let us do it in a summery way:
1- The schedule is a contract Document unless an explicit clauses in the contract stating that.
2- When the contractor forced by the owner or the consultant to give up his rights to get a claim of time, then the contractor has to make balance of the two matters.
Will he stick to his rights to make and win the time claim or he will leave his rights for another benefits or some extra compensation from the Owner.
It is his decision.

I am truly grateful for everybody’s opinion.

Although this case may not be something truly debatable that a case rarely (or maybe never) proceeded further to arbitration, this too deserves serious attention. We know that in every project, a significant amount of money is lost due to delay.

Tomas Rivera actually explained the point very well and I should not elaborate further but I want to say my piece as well since I started this issue, and after about 6 months since I started it, I gained more information regarding the issue.

Firstly, I must say that without explicit clauses in the contract stating that a Schedule is not part of a Contract, then it is part of a Contract. If without explicit statement as above, then it should be classified under “Any other documents forming part of the Contract”, this we normally see on a Contract section regarding Contract documents. Among others, correspondences, duly signed site progress report, documents showing approval of shop drawings, materials, proposals, minutes of meetings, just like approved baseline schedule (unless superseded), are all categorized under these “Any other documents…”.

Tomas is right. How then can we make all members of an organization responsible enough and ensure their commitment if a schedule is not part of a contract? Hence, in any standard Construction Project Contract, a schedule is normally part of a contract.

But going back to the original question, can a Contractor stick with the baseline schedule though each party admittedly find it not so logical?

I observed in the succeeding opinions that the issues have not merely focused on the legality of sticking to the baseline schedule, but likewise on whether this thing is fair. Maybe I over simplified my explanation in my initial thread. Perhaps I have to elaborate the situation further although I’m not sure if I can explain it clearly.

The project had been delayed due to many issues mostly attributable to the Owner. So, it was already expected that there will be time extension, the only thing to be discussed about was how much time extension should be given. Due to the urgency of the project, the Contractor was doing its internal re-arrangement of schedule to mitigate further delay, while at the same time the Contractor, the Consultant and the Owner were discussing about the time extension deserved by the Contractor. To complicate it further, the Owner assigned a target date of project completion. So the issues involved were not only time extension, but also include probable work acceleration (this was assuming that the time extension is determined to be beyond the target project completion).

The re-arranged schedule actually being implemented at site (to meet the target date of completion) have not been officially concurred by all parties pending agreement on what will be the basis of time extension and work acceleration. The Contractor initially insisted on its right according to baseline schedule regardless of the actual progress at site. The Contractor said, “lets establish the time extension first, then we can determine the acceleration period”. But Consultant and the Owner insisted, “let us base it on the actual progress at site”.

A claim may sometimes be unfair by human standard of fairness when we read the Contract in black and white. As Rex said, the logic was not smart but anyway it was not impossible, this is the Contractor’s prerogative and the Consultant approved it anyway. But in actual application, if I am an experienced Project Manager, I will not follow the approved logic if I find it not smart so that I can actually finish the work even ahead of the target date set on the baseline schedule. This I need to coordinate with all concern, such that the original logic will have to be changed officially. But why will I choose to finish the work ahead of schedule without some extra compensation from the Owner?

Now, assuming the project is delayed (on paper only) and I am a Contractor who is looking at the contract in black and white. I may pursue my case, anyway I have a basis. To the Owner’s point of view, this is highly unfair. (This is Joe’s point that the Owner would pay for the hypothetical delay).

Let us look on the Contractor’s point view based on the situation discussed earlier. The Contractor exerted all its effort to meet the Owner’s demand despite that no official agreement is reached yet with respect to time extension and a guarantee for compensation of cost acceleration, if any. The Contractor absorbed mostly if not all the impact brought by this internal re-arrangement, such as the sudden change of delivery schedule of materials, getting more staff to complete all the required drawings, importing more manpower at site, among many others. All this internal re-arrangement involved cost, and without a truly good and well implemented project monitoring system, this cost cannot be readily quantified. Because of the complicated situation, the Contractor now find it hard to determine which should govern, the actual progress at site(which was actually accelerated) or the baseline schedule? If the Contractor decided to stick on the baseline schedule, is it becoming unfair to the Owner? Without accurate data to support each one’s contention, it is hard to establish who is becoming unfair in this situation.

But let us be grateful, the Contract exists to protect each party’s right. When it was conceived by the Owner, it was deemed fair to protect the Owner’s rights first and foremost. So I must say the Contractor has the option to pursue its case and as Taher have said, “it will absolutely win a claim of time”.

But lets face it still that in most cases, even though we are bind by the contract, we cannot get away with our sense of individual fairness. Again, let us be grateful because there is a term called “negotiation” (or even arbitration) to settle this.

This is needless to say, my experience had been mostly in construction engineering, design and work methodologies. Contracts and Claims is my newest baby(about 3 years old), but I find it the most interesting because apart from the more predictable construction and design engineering, which are mostly based on established parameters, project management, contracts and claims involves varied unpredictable thoughts from countless interesting people, such as this group. Maybe we can discuss some more issues later. I’m truly pleased to meet you all. Call me Caline next time…

Let me say that we are talking generally. I agree that in some contracts, the programme is included, but generally it is not.
It is worth noting here that I made references to writings by experts on this matter. The replies did not. It would be interesting to refer to experts saying the opposite.

Another thing, as to breaking soft links in determining delays, I would like once again to refer to the FIDIC contract, and the book by Edward Corbett stating:
"There is no express obligation upon the Contractor in this clause (44) to take all reasonable steps to mitigate the effect of delays, such as would be found in many English standard forms. There is an obligation in clause 44.1 (Commencement of Works) to proceed "with due expidition and without delay" but, it is submitted, it is the phrase "such as fairly to entitle" which ensures that the Contractor will not receive extensions of time for reasonably avoidable delay."

Joe,
We don’t have to forget the 1st question sent by Carolina it was:
(Original Logic of Schedule)
(Can a Contractor hold on to the approved logic of a project schedule as one of its contractual rights?)
The answer is very simple " Regarding that the schedule is a contract document, all the contract I am working with the schedule is a contract document, then the contractor can hold on to the approved logic schedule"
And he will absolutely win a claim of time.
But as I said before not for ever he must resubmit a revised schedule avoiding the logic mistake, if any, and this submittal will be also a contract document after approved it by the consultant.
I didn’t rush it but I think it is very clear now.
Thank you for your valuable discussion and best regards.

Taher, why rushing to “nothing to say after that”!

Thank you all for your replies.

Your replies tackled one point only, the programme being a contract document or no. The second one, on breaking soft links in delay evaluation, is I believe a very important point to discuss also. I would appreciate some experts’ opinions.

Let me say that here we agree that the programme is the tool for monitoring progress and claim evaluation. However it does not have to be a contract document for it to be used as such.

You all know very well that the programme is dynamic; it is not a rigid thing like BOQs or drawings. Durations, floats, relationships in a programme are not always based on solid logic, but rather on most probable, most likely, most preferred logic. There is large room for difference in interpreting the programme between the Contractor and the Employer.
In most cases, a good detailed programme is too complicated to be understood by the high level signatories of the Contract. They are not planners; they are business men or women.

I agree with the philosophy Tomas described, but let us define first what a contract document is.
The way I understand it, contract documents are all documents signed together with the submission of tender or the signature of the Contract.
The programme is not “normally” made before the tender is accepted. It is usually a requirement in the Conditions of Contract. Its approval or consent after the start of the contract does not make it a contract document.

In my country, the FIDIC 4th edition is the most commonly used form of contract, with changes made in the particular conditions.

In the book “The FIDIC Form of Contract” by Nael G. Bunni, the author states in page 357:
“..The Employer or the Engineer on his behalf must be fully acquainted with the Contractor’s programme and with its details which must be provided in such a manner as to enable a proper assessment of its achievability or otherwise.
This is a difficult task in view of the fact that the programme is not a contractual document but only a valuable guide, and that it is required to be submitted after the acceptance of the tender and the formation of the Contract.”

In the book “FIDIC 4th, a practical legal guide” by Edward C. Corbett, the author states in discussing Clause 14 “Programme to be submitted”:
“If the Contractor’s programme or method statement is a contractual document, any ability to execute the works in accordance with the programme or method could give rise to a claim by the Contractor for a variation and costs.”
“If the Contractor submitted a programme with his tender, that programme may well form part of the contract as “The Tender” is one of the documents contained in the definition of the Contract. This could give rise to the argument that the tender programme is a contract programme with the consequences set out above. As this is clearly not the purpose or intention behind a tender programme, the parties, particularly the Employer, would be well advised to ensure that the version of the tender that is accepted by the Letter of Acceptance is one which excludes the tender programme.”
“Under clause 51.1 (Variations), the Engineer is entitled to order a change to “any specified sequence or timing of construction.” Thus, if the programme was part of the contract, it would represent a specified sequence or timing and any change to that could entitle the Contractor to a variation and payment.”

I am of the opinion of Bernard, “I would base my position on whatever was specifically agreed in the contract”.

My name was invoked, so here I am.

My experience in this part of the planet (Mexico) and having worked with international clients like american, korean, japanese and french; also, having worked as contractor and consultant to owners and contractors; I can tell you my opinion:

First of all, let me answer your question. Any document, the schedule included, is part of the contract if the contract agreement states so. If the contract agreement does not say so, then that document is not part of the contract. There might be cases in which the contract defines a procedure, say for defining and agreeing upon a schedule, and hence the schedule becomes part of the contract. In any way, this is a legal question and a lawyer should verify whether the schedule is part of the contract or not. Also, there might be cases in which the schedule is not part of the contract, but both parties to the contract use that schedule as a tool to manage the project and make decisions. And in doing so, the schedule becomes binding to the contract parties, depending on the laws of the country. I do not recall seeing a contract that does not include the schedule as part of the contract agreement.

To elaborate a little on the subject. All the contracts I have seen focus on 3 main concerns: cost, time and quality. Nowdays, projects are becoming tougher: owners want their projects at less cost, finished earlier and very important, a guarantee that you are going to comply. This requires very clear rules of the game. The project estimate or budget is the document that first determines if you are playing. The project schedule is generally in second place and sometimes in first place. If the contract does not include a schedule as part of the agreement, we are playing a very risky game, both the owner and the contractor.

Remember that many projects are serious matter, they are not a game, we are dealing with a lot of money, many times we are dealing with big penalties. We want to make sure everybody understands how the project is going to be built. We want to make sure the project has a solid plan. We want to make sure that it is executed according to the plan, since the start of the project. We want to make sure to identify any deviation as soon as posible and be able to correct it on time. We want to make sure our project, whether I am the owner or the contractor, has the highest probability of being succesful. We want to make sure we have a way of enforcing the success of the project. How can we have this assurance if we do not clearly have a schedule that is agreed upon by both parties to the contract right from the start of the project? How can we enforce this schedule if it is not part of the contract?

Somebody might have a way around it when the schedule is not a contractual document. But I ask another question: Would it not be better if the schedule were explicitly part of the contract?

One example from the contractor´s point of view. If your schedule is part of the contract, and hence enforceable, you are in a better position to claim for owners´ delays. Either or both, get paid or get an extension of time for that delay.

An example from the owner´s point of view. If the schedule is part of the contract and the contractor fails to meet the schedule earlier in the project, the owner might have the option to substitute this contractor for another earlier in the project and not at the end when there is no time to correct.

Why would somebody not want to include the schedule as part of the contract in a explicit and clear way?

In all the projects I worked on, the schedule was part of the contract as an amendment of the basic contract.
Few days ago I saw also that Ron Winter is of the same idea.
And I want to point out that I worked only on Contractor side (from PM to scheduler), while Ron from the Client one, approving or asking clarification time by time.
You can find some useful documentation from Rom at his web page
http://www.ronwinterconsulting.com/published.htm
If is not a contractual document but You out in your schedule that to be able to meet the contractual delivery date You need the cleint to approve some delivery in 10 working days and in the contract is writen 21 working days.
On what You will base Your possible claim if You go in delay also because Your Client approved the delivery in 21 working days?
How will pay the early mobilization of some sub-contractor?
As per Your statment only YOU or better Your company.

Taher,
About the programme being a contract document, I still insist on my point that it is not. If you know of any reference stating the contrary, please let me know. I repeat that the programme of works are not normally approved but rather consented on.

As to what you call mistakes by the consultant, soft or preferential links are not considered mistakes in a programme. Consultants cannot reject them, they are still the Contractor’s prerogatives that show his intention for completing the Works.
An Employer event may happen hitting the critical path. If this path contains soft links, I don’t think it would be fair for the Owner to pay for delays just because this is what the programme reads. If it is not a delay that could be physically seen on site, the owner would be paying for a hypothetical delay. I see this as highly unfair.

While appreciating Taher’s interventions, I would like to hear from other people on this subject (particularly Ron Winter, Tomas Rivera, Bernard Ertl, and others).

Joe,
You miss understand me, I’ll make it clear (Schedule is a contact document) and it is a good base for claim the consultant must pay for his revision mistake but,
Not for ever.
The contractor has to immediately submit a new schedule, avoiding the logic mistakes of the old one, for approval and this one will be also a contract document from its approval date.
Thank you

Taher,

I disagree with you that the consented program is a contract document. This does not mean that it cannot be used as a basis for a claim.
If it was a contract document, it would be binding to the Contractor and he will loose his flexibility for using any method he sees fit.
Living in the middle east, I suppose you are familiar with the FIDIC contracts. I recommend that you read the "FIDIC 4th - A Practical Legal Guide" by Edward C. Corbett, particularly the commentary of Clause 14 of the Red Book.
Other references can be easily found.

Regards

Joe,
I disagree with you any approved document is a part of the contract and it has its power from this point, or there will not be any dispute if it isn’t.
So the program is a part of the contract and from my point of view as arbitrator the consultant as he is the owner representative must pay for his mistake but the contract must resubmit a new program with the correct logic to get the approval from the consultant and replace it with the old one.

Hi Mansour: Such issues have not been seen so far in any arbitration or courts. These are minor issues only relates to prepare EOT baseline schedule to make it logical, not discussed in detail in any Legal Forum.

The programme is not normally a contract document, according to many references.
Secondly, the consultant is not normally required to approve a programme, but to give consent to it.

Does anybody know a court or arbitration case where this was the issue?

Jose,
There is another point of view approved schedule is like any other contract document.
What will happen if the consultant or the contractor found a mistake in a civil drawing? Can he construct it and say I have an excuse (It is approved before). I don’t think so!!!
Finally the contractor has to claim for time extinction for this consultant mistake but he must immediately submit new schedule avoiding this miss logic to get the consultant approval for it.

Leon,

You are true that Extension of Time is only determined on the basis of Baseline Schedule not the original schedule which is prepared by incorporating all the delays encountered at site beyond the Contractor’s control.

Mitigation of such delays is only possible if we use soft link or preferential link as required.

Joe,

I think you should use both.(extension based on approved baseline schedule or extension after breaking the soft links on the longest path?) But there should be an statused baseline schedule i.e. current schedule

Ex. If Finish date of approved baseline schedule is apr 20,2004
And Finish date of statused/current schedule is Apr 27, 2004

And Finish date after breaking soft links is Apr 20,2004
Thus extension of time is equal to 7 days.

It is really important that any basis for extension of time is based on a current schedule.

Joe,

I would resist any changes to a programme that has been approved; as you say there are no serious ligical mistakes.

I would propose that (a) for an extension of time, use the approved programme, but (b) for compensation for delay, base this on the approved programme with the ’soft link’ changes if these are realistic and acceptable.

Suppose the baseline schedule approved by the Consultant contained no serious logical mistakes.
In the assessment of the claim for extension of time, the consultant would ask the Contractor to mitigate delays by de-linking soft or preferential links.
What would you consider the Contractor’s entitlement is: extension based on approved baseline schedule or extension after breaking the soft links on the longest path?
Should the longest path determining the extension be very solid logically, or it should be adopted as is from the impacted schedule?

Let me guess.

Your consultant did not hire a professional planner/scheduler at the time they approved the schedule.

The contractor has all the right to claim for extension because it can be assumed from your schedule that both parties agreed to install the aircon after plastering works has been completed which is anyway practically possible to do but not smart. In case the logic is practically impossible to do, I believe the contractor is obligated to correct his mistakes.

Having thought about this a little more!

If I’m Dan the Plastering contractor and I’m given a programme. The only thing I am going to look at is when I need to start an activity and when I need to finish an activity.

Your not going to tell me that Dan has a P3 Planner sat in his office scrutinising the logic links. In the real world he does not.

If he is delayed in starting he will have a right to redress. That is to say if he incurrs any additional expense or needs to seek an extension of time he will be entitled to do so. He must however, be very clear and notify his client in writing at the time that the delay occurs.

The moral of this story is to review and understand the Baseline Schedule before you accept it. By the time the first schedule update is submitted, the Scheduler has preformed roughly one half of the scheduling job. Once a delay has occurred, it is too late to go back and review the previously accepted logic.

If the contractor has conceded on the logic within the original (baselined) programme. Then I think he would find it very hard to claim for an extension of time unless he had agreed by way of correspondence to re-schedule the works with a view to ascertaining the cost/time impact at a later date.

In summary he can only really claim for an extension of time if he had agreed this when the programme of works had changed, if he did not inform his client that he was in delay then I dont see how he can seek recompense retrospectively.

I amcurious however, if the AC units had an impact on the plastering. Were the external windows, doors and all the power supplies/distribution units, a.c ducting etc supposed to be complete aswell ie was this a plaster curing issue ??

Based on the information in your email, in my view the contractor has a valid claim for an extension of time.

Providing the original logic was available with his approved programme then this should be used as a base for the analysis for extension of time entitlement.
