Construction Scheduling. Do you Really Need a Scheduler to Develop and Manage the Schedule?

Does an experienced contractor really need a professional scheduler to create the baseline schedule and manage the update and revision process? Not necessarily, many projects can be scheduled using a worksheet or a simple program to model the activities and bars against a timeline.

But, does that typically provide the best schedule for managing the project? Can the contractor benefit from having a schedule professional on their team? Or at least as a third-party consultant?

Budget constraints, lack of staffing, or bad experiences with project scheduling can be some of the reasons a contractor will not have a scheduler on the project team. And, make no mistake, there is cost to this

I can understand why a contractor may be reluctant to use a professional scheduler, to a point. Some projects are simple enough and can be managed this way. Some owner-contractor relationships are strong enough that both parties trust the other will compensate them for delays or late completion.

What about the projects that really should have a schedule professional supporting the contractor with schedule development techniques, best practices and an understanding of what the schedule specifications actually require? What value do they receive when they have that support in place?

First, they should benefit from having the scheduler review the RFP specifications, prior to submitting the proposal, to review and quantify what the schedule specifications require and assist with the budget for schedule development and management. Many contractors see the specification requirement for a “CPM” schedule and assume it means a “P6” schedule or a fully resource and cost loaded schedule. A professional scheduler can interpret the schedule specification and explain the requirements for the development of the baseline schedule and schedule updates. There is much more to it than most people think there is.

Almost all contractors pride themselves on knowing how they can and will build the project, better than their competitors and for less cost than they budget for. I do not doubt this. I’ve met some great Project Managers and Superintendents and they know how to do amazing things when it comes to coordinating work and managing subcontractors.

But, they are great in their area of expertise. They are not necessarily project controls experts or professional schedulers or cost estimators. Those are specific “trades”, just like being a Carpenter or an Electrician. Most of us in the construction industry can do a little of several “trades”, but we cannot be a specialist in many trades. A few can, but I’m not one of them.

That said, a schedule professional can work with the contractor to put their plan in the program, correctly utilizing the program settings and schedule best practices, to model the plan for use by the entire project team. If done correctly, with input from all the trades and the owner, the schedule becomes a map to the completion of the project.

The schedule professional provides this map with the quality and integrity to be accepted by the owner and used to manage the subcontractors, submittals, procurement, deliveries, mobilization, and the coordination of work. The schedule also provides the Project Manager the ability to manage change order impacts to the schedule and measure performance of the various project team players.

Often, owners require the schedule to be updated and maintained as part of the invoice process. The professional scheduler supports this process by applying the actual progress to the schedule and helping the project team with identifying production slippage and schedule impacts as well as modeling revisions as necessary to revise the plan going forward.

A contractor can possibly manage a project without a schedule professional on their team. But, would they manage a project without field superintendence or materials coordination, or subcontractors for specialized work?

It’s tough to quantify what value a professional scheduler brings to the contractor’s team, but there are definitely costs to not having one. A questionable baseline schedule, the inability to project work with confidence, and the inability to accurately quantify change order delays are only a few basic functions that would be lost.

I know many of you can offer additional comments and war stories, for all of us. I welcome your comments and input. My goal, as always, is to help our industry and help the projects we support….

Construction Scheduling. What Value do Schedule Professionals Bring to a Project Owner?

Many construction project owners have specifications for the project RFP which, at the very minimum, require a CPM schedule and a specific schedule progress update process. This tells me that they take the project schedule development and management very seriously.

But, do owners always have a schedule professional on their team? Perhaps in-house, with the CMa contractor, or at least as a third-party consultant?

More often than you would think, they do not.

Maybe it’s budget constraints, lack of staffing, or bad experiences with project scheduling in general, but some owners choose to receive a simple schedule Gantt Chart pdf from the contractor and call themselves managing the project schedule.

I can understand this, to a point. Some projects are simple enough and can be managed this way. Some owner-contractor relationships are strong enough that both parties trust the other will compensate them for delays or late completion.

What about the projects that really should have a schedule professional supporting the owner with schedule oversight? What value do they receive when they have that support in place?

First, they should benefit from bringing the scheduler in early, prior to issuing the RFP to review and refine the schedule specification. Many owners use the same specification over and over and have not updated to the current schedule program outputs or schedule best practices. A professional scheduler can help develop a schedule specification that will provide the requirements for the development of a quality schedule which can be used to manage the project.

Second, they can review baseline schedule submissions and verify the contractor is meeting the requirements of the schedule specifications and following best practices to produce a valid baseline schedule.

This may require multiple iterations of the development and review process, depending on the contractor’s ability and willingness to actually develop a quality schedule. But once this is accomplished, the entire project team benefits from a baseline schedule which can be trusted to provide a sound basis for change order management and work management.

That said, a schedule professional adds value to the update process as well. They review the progress update for errors in updating the schedule such as actual dates in the future and the coordination of percent complete, duration changes, calendar changes, resource changes, schedule revisions to correct out-of-sequence work and revise the contractor’s plan going forward. The schedule has to be validated each update to maintain the integrity of the schedule network.

The schedule professional also provides the owner’s analysis of delay impacts submitted by the contractor for change orders or delays by the owner. This is not possible without all of the supporting work listed above for baseline development and update validation.

What about when the contractor is not meeting the planned production rates and the scheduled activities are getting pushed back in the schedule each update without the scheduled finish date being affected? Seems like that would be obvious to the owner’s team, but often it is a slow creep of slippage that is hard to pin down. The schedule professional knows how to quantify the slippage and identify the work driving the slippage. This is handy when discussing miracle options with the contractor.

An owner can possibly manage a project without a schedule professional on their team. But, would they manage a project without a cost estimator for scope planning or change order management? What about an inspector for quality assurance? Would an owner manage a project without being able to monitor and validate the quality of the construction?

It’s tough to quantify what value a professional scheduler brings to the owner’s team, but there are definitely costs to not having one. A questionable baseline schedule, the inability to project work with confidence, and the inability to accurately quantify change order delays are only a few basic functions that would be lost.

Construction Scheduling. Reviewing a Time Impact Analyses, TIA or Change Order Fragnet. Or, “Is this for real??”

Surprise I am sometimes bewildered by the reaction some owners have when they review the Time Impact Analyses, (TIA) or change order time extension request they receive from the contractor.

What I see, sometimes, is the owner being completely surprised that the contractor believes there was any time impact by the change order or delay. We all know that many change orders do not affect the project schedule critical (longest) path. But when they do, it gets interesting….

Let’s say the owner has delayed some part of the project in some way, but only for 3 days. When the contractor submits their TIA or change order time extension request for 5 days, the immediate reaction is usually not so good.

I find this happens more often than not because the owner does not understand how work days and calendar days work and their effect on the contract finish date.

If the 3 days happen to be 3 work days delay to the start of work on a 5 day work week calendar, it is most likely going to push the work out to include a weekend “non-work” period, perhaps even a holiday. If this happens, it will most likely push the scheduled finish date out 5 calendar days. (Most contracts have the liquidated damages based on calendar days.) In this particular case, the impact to the schedule is 5 calendar days, not 3 days.

This is can also the case when weather-sensitive work is pushed into time periods with more expected and accounted for weather days. As it should be.

How can we, as professional planning and schedule consultants help owners better understand the TIA’s and change order time extension fragnets they receive?

There are best practices and white papers devoted to the development of “fragnets”. As professional planning and schedule consultants, we should follow these best practices. But, we also need to review TIA and time extension requests to verify the “fragnet” correctly models the impact and is inserted into the most recent updated or revised schedule with reasonable logic.

Then we need to explain that to the owner to refute or validate the request. I find that once the owner understands what is driving the time from “behind the scene” in the schedule network, they tend to be more comfortable with the request. Then the negotiations can start!

None of this is possible, of course, unless there has been a disciplined process of managing the schedule development and update/revision process to maintain a valid schedule for use in validating the requests.

What other methods have you found to help with this issue?

Construction Scheduling. Key Requirements for your Schedule Specifications. Or, Owners Beware…

CPM Consultant Professional Project Management — Project Management

Do you ever find yourself pulled into projects with schedule specifications lacking even the most basic requirements necessary to establish a schedule development and management process which will produce acceptable results?

In a perfect world, we, as Professional Planners and Schedulers, would be involved in the schedule specification development. Unfortunately, more often than not, a schedule spec from a previous project, which was pulled from a previous project is used without much review for completeness or relevance to scheduling methodologies and software currently in use and endorsed.

Perhaps it would be easier to just insist on a few key requirements that at a minimum should always be in the schedule specifications. We could then edit and add additional requirements for each project as appropriate.

Each planning and schedule professional will have their own preferences for these basic requirements.

However, for me, the first thing I would add is the requirement for a CPM schedule.

This would list the requirement for complete logic to allow the production of a critical path for the project. In this requirement, I would also add the requirements for a restriction of activity durations and total float values to force the breakdown of work into enough detail to plan, manage and track the work. I would also severely limit the use of SS and FF relationships and positive lags for the same reason. I would not allow the use of SF relationships or negative lags.

Second, I would require the development of the schedule based on a WBS. This would help ensure the complete project scope was included in the schedule and make it easier for the owner’s review and verification.

Finally, I would only allow two activities to be constrained; all activities percent complete type set to physical; development of appropriate calendars for weather and other non-work days; and require manual updating of progress with correction of out-of-sequence relationships and any other schedule revisions done in a two-step or bifurcated update process with the submission of the update only and then the revised update as separate parts of the update package to allow owner review of actual progress and the impact of this to the existing schedule with follow-on review of plan corrections.

We could address resource, crew, cost, and activity code requirements as needed for each project. But at least we could start with the basics for schedule development and management.

This would help all of us in the industry.

What other requirements would you add as basic requirements to help with this issue? What requirements would you not include?

Construction Scheduling. How do we, as Schedule Consultants, “Value” our Services?

Question Do you provide proposals to contractors or owners for your schedule development and management services? Do you provide a lump sum hard bid based on the project? Or, do you provide an hourly rate for your services? Which is best? Are there circumstances that make one the better choice?

I still struggle with this issue.

At some point, all of us are asked to propose on a project.

So, what do you do? What do you use as your guide for setting a lump sum price proposal? Do you estimate your hours based on past, similar projects? How do you account for relying on a new project team for input and reviews?

Do you provide an hourly billable rate? How does your client budget for you services? Do you provide a budget estimate of hours and your rate for their use?

I typically provide a budget estimate based on my estimated hours and billable rate. But even then, coming up with the hours for a new client and team, and hoping for proactive input for development and updates/revisions is very subjective. But I do my best to provide a budget estimate they can have confidence in.

There must be a better way to go about pricing our work based on the value we bring to the project.

What works for you? Have you figured out a “safer” way to price the project scheduling services you will provide?

I believe that we, as planning and scheduling professional consultants, should strive to provide the best possible schedule support to assist the project team with providing a successful project.

The question is: As consultants, how do we “value” this?

We must always maintain our integrity and be honest with our client.

What has your experience been?

Real scheduling is messy. But we all deal with issues all the time…..

Construction Scheduling. Why are there no schedule requirements in the RFP?

person-question-300x300 Are you ever asked to develop the project baseline schedule and find out there are not any requirements for the schedule in the contract documents. It could happen…..

Or the requirements are “fuzzy” at best or so limited as to be of little value.

At some point, all of us have come across this scenario, or soon will.

So, what do you do? What do you use as your guide for setting the critical path, activity and duration types, and resource and cost loading? Does your company have guidelines for this situation? Do you have a preferred method you fall back on in these situations?

I have a couple of guidelines based on useful schedule specifications I’ve worked with in the past. But I have to find out what the project team wants from the schedule before I can decide which requirements to employ.

Does your client want to project and track progress using resources? Does the owner? Does your client want to use cost loading? If so, by unit cost or lump sum? What does your client expect or understand about setting the critical path? Will the project be resource driven? Or will durations and logic rule with resources handled via logic? What about constraints? Calendars and weather days?

There are many more variables we work with every day. Without schedule requirements for the project, we are left deciding which settings and approaches are best for the specific project. With experience, we can become comfortable with this situation. But what if the project is a new industry or contract type for you?

How do you approach these situations in your company?

I believe that we, as planning and scheduling professional consultants, should strive to provide the best possible schedule support to assist the project team with providing a successful project.

The question is: As consultants, how do we accomplish this?

We must always maintain our integrity and be honest with our client.

What has your experience been?

Do you just default to the simplest methods and settings?

Do you advise your client to convene a team meeting with the owner to see if they can agree on some basic requirements?

Do you just pull one of you favored specifications out of the drawer and run with that?

Real scheduling is messy. But we all deal with issues all the time…..

Construction Scheduling. Which Baseline Schedule is the Project Baseline?

Ideas All projects run into change orders and delays. We also need to measure and track progress against the original plan. Baseline Schedules are necessary for this.

But, how do we manage baseline schedules?

There are those that believe we always measure against the original baseline. This would be fine if the project never incurred a change order that changed the scope, worked out of sequence for whatever reason or suffered a delay of some kind.

The ugly truth is that no project or schedule is immune to change. As a planning and scheduling professional consultant, we see the proof of this all the time.

What does this mean for the Project Baseline Schedule?

Part of what we do, as a planning and scheduling professional consultant, is to help the contractor develop the Project Ideas Baseline Schedule. We also update and maintain the schedule over the life of the project

Each time the schedule is updated and accepted for use as the schedule update for the period, the updated schedule essentially becomes the “new” baseline schedule. This update represents the plan to execute the remaining work on the project and as such is now the “new” plan or baseline.

Sure, we can always refer back to the original project baseline schedule, but to what end?

If a change order is added to the work which significantly changes the scheduled work or a delay is allowed, we need to “re-baseline” the schedule. The team reviews and agrees to the “new” or “revised” baseline and we keep the project moving.

Construction Scheduling. How do we, as Schedule Consultants, Best Serve the Client?

schedule1 As I start working with new clients, I seek to understand how I can best help them?

What do they expect to gain from me? I know they want a project schedule developed and approved for use on the project. That’s only part of it…….

A large part of what we do, as a planning and scheduling professional consultant, is add to our clients’ knowledge base. We teach the importance of using schedule best practices, ways to better manage and use the schedule, and how to better understand what the schedule update is telling us.

I enjoy all of it.

I believe that we, as planning and scheduling professional consultants, should also improve the clients’ understanding of scheduling in general. We should improve the clients’ ability to deliver the project. We should help the client understand better how the project schedule integrates with their cost and resource management.

What has your experience been?

Do most of your clients already integrate their project schedules with their resource and cost control practice? Do they only need your expertise with the software and schedule techniques?

Or, do you sometimes find your efforts resisted due to your clients’ lack of schedule knowledge or project management maturity? If so, how? And how do you deal with that?

Do you often feel pressured to develop the schedule based completely on best case scenarios? If so, how do you deal with that?

What client management techniques have you developed to better manage and help your clients with their schedule development and management?

Schedule Consultants. What should a Project Owner Consider when Deciding which Planning and Schedule Consultant to Choose?

How does a project owner, working in an organization without an in-house planning and schedule professional, know what to look for in a planning and schedule consultant? You are going to trust this person to monitor and report on the contractor’s schedule development and updates and revisions for your project. How do you know which schedule consultant from the multitude of schedule consultants to choose?

Cost should definitely not be the deciding factor.

Cost is not indicative of the quality of service you will receive.

Should you go to a large multi-disciplined construction management (CM) firm or an independent expert (schedule consultants) in the field of scheduling?

If you have other work you need assistance with and the CM firm has the expertise to provide it, then it makes sense to use the CM firm, if you don’t mind the markup on the services. If all you need is assistance with the project’s schedule management, then it may be a better idea to go with the consultant.

There are many consultants providing schedule oversight and management services. Most are very good and it is really a matter of how comfortable you are with the individual. However, there are schedule consultants that specialize in software operation, but not so much in understanding construction sequencing and methodologies. It’s hard to find an old project or construction manager that became a scheduler. That would be the best, provided they learned all the Association for the Advancement of Cost Engineering International (AACEi) and other industry best practices. Unfortunately, many of the old project and construction managers knew how to manage the project but didn’t understand how the schedule was developed or how to recognize the application of the AACEi and industry best practices in their schedules. If you can find a Construction Management Association of America (CMAA) Certified Construction Manager (CCM) or Project Management Institute (PMI) certified Project Management Professional (PMP) with an Association for the Advancement of Cost Engineering International (AACEi) Planning and Schedule Professional (PSP) certification or PMI-SP certification, you have found someone with proven project management and schedule development skills. This would be a great choice.

A few of the things you should consider when deciding which schedule consultants to use are:

Has the consultant scheduled or managed work similar to the project you need help with?
Has the consultant scheduled or managed projects of the size project you plan to have them help you with?
Does the consultant have the time to devote to the development phase of the planning and scheduling process?
Is the consultant approachable? Ethical? Going to look after your best interests?

Once you have decided on which consultant to go with, you will need to provide them with some contract information and will also want to be involved with the schedule review and analyzation process. This will help you understand what construction schedule consultants are looking at and why. Schedule consultants will analyze the software calculation settings, types of activities used, calendars, resource loading, use of lags, total float values and the reasons for anomalies, and many more detailed items that work behind the scenes in a critical path method (CPM) schedule. You really need to stay involved in order to understand what is being found and the impact it has on the schedule. Professional planning and schedule consultants will produce a report that lists any problems in the schedule construction or settings or approach that in their professional opinion is a concern which should be reviewed with the contractor. The schedule consultant does not want to cut corners or create strained relationships that will undermine the project team’s effectiveness. Listen to what they recommend. Schedule consultants only want to provide you with their analysis of the schedule, based on AACEi and industry best practice and your contract requirements.

Scheduling Consultant. Why would a Project Owner need a Professional Planning and Scheduling Consultant? Isn’t the Contractor Responsible for the Schedule?

It is surprising that many project owners don’t obtain any assistance with managing the general contractors’ schedule. They have PM’s on staff who look at the Gantt Charts and perhaps ask about milestone completion dates or basic duration or logic details. Universities, financial and medical groups usually employ a Construction Manager as Agent (CMa) to help with very large projects; other times they choose CM at Risk as the project delivery vehicle. Only they don’t have anyone as their schedule advocate after the project goes to construction. Or if they have medium and small projects, they don’t employ any CM assistance with at all.

The Gantt Chart is not much value to the owner if they don’t know how the schedule settings and calendars and logic are set up. Most PM’s on the owner’s team don’t have the background, training or experience to look at the schedule and check these. They really need someone to help them review the schedule development and update process to work as their advocate. That someone is a Professional Planning and Scheduling Consultant.

Without having the ability to open the schedule and analyze the settings and data, the owner has no way of validating the schedule as presented. While contractors don’t intentionally produce schedules that do not meet the contract requirements, it happens all too often. The only way to know is to have the training, experience and ability to analyze the schedule file.

The owner really needs to know what the schedule calculations are set for. Is it retained logic or progress override? How is the “critical” path determined? By longest path or a total float value? Are calendars established, and if so are they assigned to activities? What type of percent complete is selected? What type of activities are in use? Are there lags in use? All of these settings and selections impact how the schedule calculates. The owner should have specified requirements for these, and other items. The owner also needs to be able to check these.

The contract typically requires the use of a minimal set of activity codes. If it does not, the contractor should include at least a few activity codes for their own use. There is no reason the owner can’t use these activity codes to help group, filter and sort the schedule activities for their own use in analyzing the schedule for resource usage, area congestion, and activities specifically coded to the owner for responsibility. The owner can always request this from the contractor, but why shouldn’t the owner be capable of performing these tasks? Even if it is through the use of a professional scheduling consultant. That way they know exactly what the filter, layout, and grouping is set for.

And finally, why can’t the owner use the most recent update to run “what if” scenarios? Perhaps, in addition to creating a preliminary cost estimate for a potential change order, the owner creates a draft fragnet and adds it to the schedule to see what the potential time impact could be? This would certainly help with documenting and supporting the business decision to issue a request for proposal for a change order. How many times has an owner issued a request for proposal only to determine the price or schedule impact is too great after the contractor develops their proposal with time and cost included? This just wastes the contractor’s resources, often results in the contractor holding the start of the work being changed to prevent rework, and allows the owner more control over the project’s change management.

This is a simplified version of the topic of owners using a scheduling consultant or CMa services for schedule oversight and intended only to create thought and discussion of the issues surrounding this topic. Many owners aren’t aware of the benefits which having the ability to really analyze the schedule will provide. They have gotten by with looking at Gantt Charts so far, why should they change now?
