What is Integrated Project Delivery (IPD) and how does it contribute to total team collaboration? Think what it would be like if key stakeholders on capital projects got together to proactively plan issues in advance, equally sharing risks and rewards for success. Having all the parties involved from project conception can be the difference between project delays that cause a budget nightmare or a smooth, timely venture that stays on task and can even save money.

Why Integrated Project Delivery?
This process uses the insights and talents of the capital project team to process design and construction issues in a collaborative way. The three key project stakeholders, usually the owner, contractor and architect/engineer, are legally connected through a joint contract, becoming joined-at-the-hip, for better or for worse. In this way, each party has a truly vested interest in the performance of the other parties. This new business practice is leading a new wave of sustainable project delivery by avoiding missed communications and misunderstandings that have long marked the industry.
How Does IPD Work?
Using the IPD project delivery method, all parties involved on a project are assembled as early as possible, before anything is designed, to provide their collective expertise to the development of a project. To incentivize the different entities, contracts are established upfront with shared risks and shared rewards, with the understanding that all parties are working together for the good of the project.
This type of integrated project uses innovative business models to support collaboration and efficiency. All project team members must agree to basic principles of collaboration in order to succeed. Most importantly, there must be a high level of mutual trust, with respect, open communication, understood mutual benefits and project-focused goals. To strengthen these elements, the key stakeholders need to have straightforward conversations about project issues and share their experience and knowledge to proactively steer desired, positive outcomes. These discussions bring clarity of management decisions, purpose and team cooperation to build trust from the inception of the project.
Transparent information sharing is extremely important for seamless collaboration to occur. One tool that is frequently used is Building Information Modeling (BIM). BIM is a digital representation of physical and functional characteristics of a built project. It serves as a resource of shared knowledge and forms the shared basis for decisions during its lifecycle, from project inception through operation. In addition, programs and tools that help to transparently distribute, mark-up and manage project drawings and documents can be extremely useful to share the same information at the same time.
Most important, however, is the need for reliable and proactive leadership from all key parties that looks for win-win solutions and seeks to understand underlying interests, needs, and positions.
How Does IPD Manage Risk?
For IPD to work, risks should be equitably allocated between the collective parties and balanced with rewards. IPD turns the standard contracting language around through a blending of "transactional" and "relational" contracting.
A "transactional" contract is simply where exchanges are made for goods and services. The structure of a typical transactional design or construction contract can have hidden "costs" by inhibiting coordination, stifling cooperation and innovation, and rewarding individuals for reserving good ideas and optimizing their performance at the expense of others. In contrast, "relational" contracting aligns project objectives with the interests of the key project parties.
By blending both transactional and relational contracts, the parties externally enter a classic transactional contract with the client, some suppliers, and internally, members are bound by a relational contract that is described in a "pact." By binding the parties together in a partnership for the duration of the project the pact minimizes the hidden costs of transactional contracts.
What Do the Results Look Like?
By collaboratively aligning the team, the project excels through minimizing waste, loss of time and poorly utilized resources. The effectiveness of all the design and construction phases is markedly improved. The integrated team process produces lean logistics, shorter time schedules and better management. Projects are improved from the beginning and green design ideas are better understood within the whole team. The projected results of integrated project delivery are a higher quality project for a lower cost.
Keys to Success
The key to a successful project that uses the Integrated Project Delivery method is to assemble a team that is committed to building trust and using collaborative processes to work together effectively. Thus, the essential skills of leadership and communication are essential. While these skills can be taught, because of the very nature of this process, these skills must be carefully evaluated and selected at the outset. Project stakeholders must be particularly fastidious to consider not just a company's or individual's resume, but also call references to get BIM modeling the "real scoop." With IPD, one bad apple may not just destroy a project, but the entire project team!
By now we all know that BIM stands for building information modeling though it's easy to dismiss it as just a new software for MEP modeling faster and to extract drawings more easily. In truth, there is a lot more the MEP design element of the project than simply the modelling phase. As MEP (mechanical, electrical and plumbing services) are at the heart of BIM any conscious construction manager would be wise to produce MEP drawings from a real 3D model as this is the only way to reliably manage clashes and generally handle the complexity of coordinating MEP with the architectural and structural direction of the project. This is known as MEP Design and 3D MEP Coordination.
In practice, MEP is not just about modeling the components the various disciplines involved require. This is because in any moderately complex scenario, quality MEP Design Services, properly implemented, can insure the client that the drawings delivered will be workable by the contractor without costly subsequent changes. Such changes are a typical occurrence on a worksite, primarily stemming from fabrication difficulties that can easily arise. In this sense a BIM approach is, again, the only obvious choice. But implementing MEP design requirements isn't often straightforward.
Different use case scenarios impose significantly different requirements, often mandatory by local laws and regulations but in any case aligned with best practices, focused on delivering an efficient and ergonomic building. Specialists providing MEP Design Services will have all the know-how required to compute the sizing and distribution of MEP equipment and will insure compliance with any regulations. What they can't do is know in advance how exactly will everything fit together, especially for a project that is at least moderately complex. Complexity can come from the size of the project but also the future use of a facility can generate complexity. At this stage, MEP 3D Modeling becomes important and BIM modelers will step in and work on data provided by the MEP design team. It's here where much can be gained from close interaction between the two factions. As the model progresses, innovative, more ergonomic and/or often more practical solutions can take shape and save the client money and construction time by adjusting the design to account for the actual spatial constraints. Such constraints can suggest the relocation of piping or clustering HVAC equipment alongside other installations when shafts are over-sized, for any reason, and many more similar core design decisions. In some cases the most effective 3D MEP Coordination solution is achieved when the MEP Design Engineering team collaborates with the MEP 3D Modeling team closely.
Given the complexity of MEP and the deep specialisation that it requires, outsourcing is a valuable tool for design specialists and consultants especially as collaboration under a BIM work environment is becoming increasingly more frictionless. It's seldom that an MEP design firm will have the market conditions to justify investing on in-house MEP modeling resources and in some cases even an extensive Design Engineering team. In this scenario outsourcing becomes the norm although too often this is limited to a narrow, local talent pool while significant costs can be saved by searching globally. Also when looking locally, the outsourcing ends up being split between MEP design and MEP BIM services. Here, fragmentation is something that can end up costing valuable time, and subsequently money, on the part of the managing party. In this scenario it becomes evident that the best practice would be to rely on a specialist that can handle both MEP Design Engineering and MEP 3D Modeling. In this way any gap between design and modeling is closed and any problems can be solved in an iterative fashion. The same iterative process that will also ensure quality MEP Coordination on site. Having both departments working together enables all the benefits mentioned above. Having a competent and all inclusive service provider outsourced brings yet another set of benefits.
In conclusion, outsourcing MEP services can be done in a variety of ways. Not all of them are equal and finding a reliable partner that will communicate efficiently and coordinate with the contractor should always be balanced by the ability of that partner to handle both MEP design & MEP BIM services so as to ensure a smooth implementation of one of the most important aspects in the construction of a project.
