When it comes to complex building projects, Building Team member firms that deliver design, engineering, and construction services bring very different perspectives to the job.
This presentation is a must for owners, contractors, and engineers who are (or soon will be) working on a project using the GMP format of project delivery, want to enhance their practical working knowledge of GMP contracts, and seek to avoid the pitfalls of this innovative project delivery format. 10 Things to Consider when Contracting with MEP’s on a GMP Basis Using a lump sum contract is a typical approach to contracting with mechanical, electrical or plumbing (MEP) subcontractors. Assuring Best Value in Progressive Design-Build WHITE PAPER The prevalence of Progressive DB, which utilizes and subcontracts. Additionally, the owner is able to receive a full accounting of all other project related costs including any contingencies, overhead and profit. develop a Guaranteed Maximum Price (GMP). The GMP.
Design is all about possibilities. Engineering is about rooting those ideas in reality. Construction is about getting the work done.
As a result, when a building moves from design to engineering to construction, inherent hurdles and inefficiencies must be overcome.
Change orders create delays and add cost. Accountability and ownership can be ambiguous. Key details can be lost in translation. Yet all the players share the same goal: Design-assist DA is a procurement method by which one or more subcontractors are retained, prior to the completion of design, to assist the architect, engineer, or construction manager in the development of the design and construction documents.
This is not always an obvious solution. The project owner may engage a CM for preconstruction services to provide insight into the overall cost, sequencing, and constructability. When the design is completed, the construction documents are published and turned over to subcontractors for bidding.
Subcontracts are awarded, and the process of coordination, shop drawings, and procurement begins. As discrepancies arise, the design team is called upon to answer requests for information or modify the construction documents, often resulting in delays, change orders, and added cost.
Too often, design-bid-build fails to fully capitalize on the strengths of all parties and often creates adversarial relationships among the various entities.
The DA process changes this dynamic.
With DA, the Building Team determines how each party can best contribute at each stage and when transitions should occur to maximize efficiency. DA subcontractors typically do not assume design liability; they assist the architect and engineers of record with input as the design develops.
They do, however, understand and embrace the project goals and priorities and assume some degree of ownership of the design. In most cases, this results in a reduction in coordination-based RFIs and change orders.
Its benefits include improvements in design efficiency, cost management, speed to market, and constructability. DA is best leveraged when early engagement of certain subcontractors is most beneficial for the project.
Involvement of DA subcontractors earlier in the design process reduces redundancy inherent in the traditional design-bid-build process and helps subcontractors detect and resolve constructability issues before construction starts.
The result is a reduction in design-related RFIs during construction, when the potential for budget and schedule implications is the greatest.
The structure was steel frame with composite concrete slabs. The skin was architectural precast concrete with some curtain wall and glass. Four design-assist contractors were needed: A request for qualifications was issued; then, the owner, the architect, and the CM narrowed each trade down to the three most qualified firms.
The responses to the RFP were reviewed, interviews were held, and the final selection was made.
The four firms were brought on board at the end of design development. At that point the Building Team decided to convert the steel and precast work to a lump-sum contract. The mechanical and electrical contracts continued as GMPs throughout construction.
In retrospect, the decision to incorporate DA subcontractors at the end of Design Development may not have been the best. Due to the complexity of the project especially the MEP systemsdoing so still proved beneficial, but it might have been better to have had the subcontractors on board at the beginning of Design Development.
All four contractors were able to stay within the original project budget. Care should be taken during the subcontractor selection process to understand how familiar a subcontractor is with the process of managing a cost-plus contract. Design-assist also creates a collaborative environment for the design and construction team to work toward a common goal of producing the best building for the owner.
Communication is improved throughout the project by ensuring that all members of the Building Team fully understand the goals and priorities of the project.• The MEP/CMP/GMP gates can be more clearly defined by increasing the Progenitor Cell gate to include the double negatives.
This increases the CD population and is a useful guide for gating. 10 Things to Consider when Contracting with MEP’s on a GMP Basis Using a lump sum contract is a typical approach to contracting with mechanical, electrical or plumbing (MEP) subcontractors.
