BIM-based tools provide new methods of mitigating safety hazards and risks through the integration of 3D models by taking into account of construction procedures and safety knowledge. The implementation of BIM in design stage is believed to predict and prevent any possible construction accidents. Likewise, time-related information and 3D models data (4D BIM) linkage could further enhance the site safety through the utilization of simulation and visualization features. Besides, the visualization feature could ease designers for effective detection on time-space conflicts that able to prompt hazard recognition (e.g. fall identification), and enhancement on communication among designers and builders (e.g. virtual reality safety dialogue).


4 Steps of Risk Evaluation & Mitigation in Design Phase

a) Safety risk quantification for design elements and construction activities

  • Risk was firstly quantified by using survey results from construction field personnel at activity level, then the cumulative results were used to assess the risk in accordance to each design element.

b) Incorporation of risk scores with 4D BIM Model

  • Linkage of quantified risk values with corresponding design elements in the 3D model
  • After unit risk and quantity information gathered, the risk associated with an object can be quantified or calculated

c) Project risk simulation and risk assessment analysis

  • Visualization of construction sequences on a timeline for the entire project and promote collaborative environment for both designers and constructors including unscheduled design elements recognition
  • Synchro PRO as the 4D Modelling software enable the daily risk for each task to be calculated

d) Design alternative selection

  • Revision on the design at object level could be done by designers with collaboration of contractor to adjust the project model and schedule to mitigate the accumulated risk (Process of revising design could be repeated until identified risk is acceptable)

BENEFITS of BIM Modelling (4D) for:

Designers Contractors
Gain idea on risk levels for each building system & design option Discover deficiencies in schedule and offer input during early stage of project to improve effectiveness of risk assessment
Acknowledge the presence of high-risk tasks Enhance on safety resource allocations within high-risk period or work area
Adjust designs to eliminate the hazards / substitutes in less hazardous materials or design components Use risk information to re-sequence high-risk activities through risk levelling in construction

Why use 4D safety planning?

Safety planning methods that are currently in practice have reached or are very close to reaching their practical safety improvement potential. To further bring down the number of safety incidents in the construction industry, a breakthrough in safety planning that surpasses current best practices is required. Virtual design and construction (VDC) enables the visualization of construction activities before they occur, it could be the tool that makes this breakthrough possible. Thus, construction safety research has recognized that the ability to influence safety in a project is highest at the earliest stages of that project such as the design and planning phases. This concept can and should be applied to shorter timelines such as the look-ahead window, the workweek, the workday, or even at the operation level of each activity (e.g. in power plant component replacement planning)because every bit of safety matters.

Case Study: Safety Planning with Synchro at Pearl Harbor Hanger Renovation

The Safety Lead, Blake Mead, and VDC Lead, Angelo Lago, for Hensel Phelps Pacific Region had plan and successfully execute the renovation of a hanger in Pearl Harbor, HI with increased safety and more efficient production by using Synchro Software. Blake and Angelo had discuss to improve safety planning using Synchro as Blake became fimiliar with BIM and Virtual Design and Construction (VDC).

The project is a renovation of a 260 x 100 sq. ft. hanger on Ford Island in Pearl Harbor, HI. The project removes all hazardous materials, upgrades the structure to Anti-Terrorism/Force Protection (ATFP) blast rating, improves overall structural capacity, repairs roof damage, adds beams to the attic space, removes piping fire sprinklers and updates interior finish.

To visually show safety hazards in the model, safety icons created by Synchro were placed in the location and time of the hazards. Their regional VDC leads regularly meet to share best practices and push the implementation of 4D Planning, which is part of the VDC toolkit.

Upon reviewing the initial plan sequence in Synchro, it was apparent that they could perform specific studies and alternate sequences before the roof demolition to optimize the plan. The initial plan seemed great, but visualizing it showed that the order of replacement caused additional hazards. Thus, the plan was simplified, made more productive and safer in overall.

The project requires safety meetings with all trades for each phase three weeks prior to the start of work and walk through the sequence to identify any hazards in the environment or the job procedure so that each step of the entire job can be done safely and efficiently. By showing the Synchro model live, they were able to expand the Gantt view, show dates and tasks, and the objects that are related to them. The trades can immediately react, like when a warning line was not safe enough and they needed to use fall protection to get access.

There is simply more clarity looking at the visual plan. In addition, the trades were more calm and confident- and calm, confident sites are safer sites. As part of the renovation, the VDC team performed a laser scan of the high bay, mezzanine level, attic and roof to create an accurate as-built BIM model. An as-built model was created in Revit and then imported into Synchro to show the sequencing of work for the attic and roof.

Synchro makes safety planning proactive, easy to communicate and engaging for the trades.

4D Construction Planning and Scheduling is the new way to enable digital creation of the approved project delivery approach. It facilitated through the development of specific project plans and schedules that combine 3D data and time data into a single integrated model.

In other words, 4D puts the project plan into real context, requiring the deployment of a clearly specified 3D Construction Planning and Scheduling process together to improve the delivery team’s ability to identify, manage and remove the multiple and compounding instances of waste caused by errors, confusion, and inefficiency in the planning and execution of projects.

OBJECTIVES

The focus and purpose of 4D Construction Planning and Scheduling is to enrich the planning and scheduling process to achieve improved communications and stakeholder participation. It enables the creation of a robust delivery approach that can be understood, validated and reliably implemented by the project delivery team.

Owners should insist on seeing a 4D Plan as part of the Contractor’s BIM Execution Plan and the 4D Plan needs to include more than just a series of animations. It also generates visual reporting of construction schedule through the entire life of the project, including jobsite status updates. Synchro 4D Planning tool provides Real-Time Advanced Graphic Simulations, Real-Time Collaboration, Dynamic Communications, Baseline-Actual Comparison, Lean/BIM Integration, Dynamic & Static Clash Detection and Optimize Delivery Approach. For owners, the bottom line is simple-without 4D they are missing a big opportunity to save time and money altogether.

EXAMPLE OF BENEFITS

  • Reduction in lost time in the project execution due to – Time lost in dealing with rework in the field caused by unplanned workspace clashes; Time lost in the field due to extra meetings convened to “talk through” the confusion in the schedule; Time lost in the field due to the occurrence of unplanned safety events that could have been avoided
  • Reduction in mistakes in the field caused by lack of needed information due to – Assuming a construction plan can be developed based solely on review of the design model; Assuming the initial schedule forecast is suciently accurate based on unverified/ unreview inputs; Assuming a construction sequence is flawless without a thorough review by all stakeholders of site logistics and temporary works
  • Reduction in the margins (cost avoidance) by removing unnecessary conservatism due to – Additional “float” in scheduled activities to account for “assumed delays”; Additional space allocated for activities to account for the possibility of congestion; Additional time for contractors to be on site

Linking BIM to project management tools in an accessible and affordable way brings huge benefits to the planning process and the efficiency of construction. 

4D-Planning in construction management is a method of visualizing the schedule. This method is based on Building information modeling (BIM) which is a process that came to revolutionize the work -flow of the Architecture, Engineering and Construction (AEC) Industry. The fourth dimension of BIM focuses on linking the 3D geometrical models with time and scheduling. The visualization of the schedule using 4D planning methods if combined with other scheduling methods facilitates communication and decision making throughout planning and construction phase. The opportunities of 4D planning also improve procurement management and spatial constrains reinforcing and supplement the location-based scheduling. Another approach that gains more and more ground is the linkage of 4D BIM with the Lean construction practices. This article investigates the values and benefits that 4D Planning intends to create simultaneously with the barriers and constrains that need to be addressed to minimize the cost and time of construction projects and maximize the benefits and effectiveness; how 4D planning supports some of the most common scheduling practices is also a matter of interest.

By combining 3D models with scheduling tools in one application, 4D Planning and Controlling enables you to use the visual power of 4D planning to:

  • Model-based scheduling and model-based estimating help the team to work on measurement details of the structure. 4D immediately increases the predictability and profitability of the project, delivering them on budget and on time.
  • Ease even the biggest of projects’ way from sketch to actual construction using 4D. Taking the advantages of 4D to bring out the most effective communication among the building team members.
  • Identify problems that may not be visible via traditional schedules
  • Run scenarios to assess feasibility of execution and find the best solutions
  • See the impact in the 3D view as you update the Gantt chart
  • Study how the build process will appear at different project stages
  • Integrate as-built information
  • Create better tenders, faster
  • Optimize your budget by careful scheduling

What is Building Information Modelling (BIM)?

It is a process for creating and managing information on a construction project across the project lifecycle. One of the key outputs of this process is the Building Information Model, the digital description of every aspect of the built asset. This model draws on information assembled collaboratively and updated at key stages of a project. Creating a digital Building Information Model enables those who interact with the building to optimize their actions, resulting in a greater whole life value for the asset.

How can BIM helps you?

It assembles all of the information about every component of a building, making it possible for anyone to access that information for any purpose. Thus, the risk of mistakes or discrepancies is reduced, and abortive costs minimized.

BIM data can be used to exemplify the entire building life-cycle, from cradle to cradle, from inception and design to demolition and materials reuse. Spaces, systems, products and sequences can be shown in relative scale to each other and, in turn, relative to the entire project. And by signalling conflict detection BIM prevents errors creeping in at the various stages of development/ construction.

Construction companies began adopting CPM in the late 1950s and early 1960s. Critical Path Method (CPM) is project modelling technique developed in the late 1950s. By the late 1970’s and early 1980s, the personal computer made CPM affordable and accessible to the masses; so how has construction performance fared since CPM became the standard for construction planning and scheduling? For years, we have all seen the numbers and charts put up for debate showing no evidence that the original hopes and excitement of CPM is living up to its original expectation.

In construction, the CPM model is based on the input of individuals who use personal experience and historic project performance to inform their work. People must read 2D design documents showing what the project looks like first at the start (existing conditions) and what the finished project will be on completion.

To be clear, the construction delivery approach, the field operations plan, is created from the imagination of a person(s) who is required to envision the activities, duration, and dependencies of the specific project from seeing the existing conditions at the start and the construction design for the completed project at the end. Once created, they can review the delivery approach with others using the Gantt chart or network diagram.


It will never going to be enough to improve construction performance if CPM alone. Project today are more likely to end in a dispute or claim rather than be completed on time or on budget, lawyers love the baseline versus actual CPM artefacts to help sort out the mess. CPM should remain part of the foundation for planning, scheduling and the controls systems required for managing construction operations and it will continue to be required for the foreseeable future.

How can we improve performance?

Start by recognizing that 3D design changes everything and drives complexity, and for at least 60 years all engineering lead industries have known it. BIM is organised and structured by 3D spatial model. Today, many construction projects utilize 3D models for the final integrated product design’s spatial coordination to avoid fabricating and installing any component in the wrong location before production operations begin.

When it comes to 4D, the industry falsely led to believe that creating a schedule by reading 2D drawings and keyboarding into the legacy CPM software and then linking the CPM to the 3D model is right. SYNCHRO Software is doing 4D. Creating construction operations directly from 3D model at any level of 3D model detail is where 4D is the best. The critical path network and 2D documents are the derivative, they are outputs of 4D. 4D leads construction companies’s workflow and has envolved their construction management processes into the modern digital age.

Critical Path

Critical path project management (CPM) is a technique used to complete projects on time by focusing on key tasks. One path through all the inter-connected tasks is the fastest avenue to take when completing any project. By focusing on the tasks that make up the critical path, the project manager maximizes the chances of completing the project on time.

Longest Path

The Longest Path is the longest continuous path of activities through a project, which controls project early completion. It is possible for otherwise defined critical path activities to not be on the longest path and longest path activities to not show calculated critical float.

Is there overlap between Longest Path and Critical Path?

Let say it this way – the Longest Path is a Critical Path, but not all Critical Paths are the Longest.

Because we can alter Critical Path through constraints, actuals, deadlines and other mechanisms, often we end up with a path that has more Critical activities than would be on the Longest Path.

If you start with a baseline schedule that has no actuals, no constraints and no deadline, and you perform some CPM scheduling on it, the path of 0 Total Float will be the Longest Path. If you add up the durations of all activities on that 0-float path, it will have the longest Total Duration.

If you calculate the Longest Path for a project that does have actuals, constraints, a deadline, etc, you will come up with a path of activities that are “important”, need I say “small-c critical” to the timely completion of the project.

Which one should I use?

I would strongly suggest you get to know your project’s Longest Path and monitor it. What the client wants to see might be something else, but the timely completion of Longest Path activities leads to your project finishing on time.

Most software packages let you track both Critical Path and Longest Path. Track both.

Lastly, I would advocate educating yourself on how the software that you use defines Critical Path and what sorts of things (constraints, relationships, lag,  etc.) will affect an activity’s Total Float.

It is the path of 0 Total Float Through the project

Critical path project management (CPM) is a technique used to complete projects on time by focusing on key tasks. One path through all the inter-connected tasks is the fastest avenue to take when completing any project. By focusing on the tasks that make up the critical path, the project manager maximizes the chances of completing the project on time.

No Project Deadline

By setting a deadline on the project (a Must Finish By date in Primavera P6), it results in the appearance of negative Total Float if you are late, and positive float if you are early.

No Constrains

Constraints affect an activity’s Total Float value. Constrained activities can show negative Total Float and can drive negative float to their successors or predecessors. Applying constraints throughout a project will affect what activities are Critical. And so, again the path of 0-total float through the project eludes you.

No Actual

A project with actuals may not show a path of 0-float either. The actuals and the order of execution can affect the activities’ Total Float as well.
