Life Cycle Analysis

Early involvement of the preconstruction services team allows systems specialists to look beyond the initial project construction costs and into the issues of operation costs, maintenance and replacement costs of alternate systems. The result of this analysis is the identification of the best long-term system investment for the project. Evaluation of first costs vs. overall cost over the life of the system is the focus.

Cost Estimating

The key to every project’s success is the establishment of a comprehensive budget. We work with the designers to understand the key elements of the design, and prepare a narrative of the overall project system by system so the scope is clearly communicated. We develop a preliminary schedule for design, procurement and construction activities to determine what critical information is needed. Our team of estimators develops a initial budget based on the current documents or narratives. We clearly itemize every assumption or plug number, whether shown on the documents or not. We review our assumptions with the project team and make necessary adjustments. Once we agree that the assumptions are valid, the estimate becomes the benchmark against which all future decisions are made and this constitutes the team’s target budget. The target budget is updated at specified milestones. Often specialized estimates are completed to analyze alternatives to specific building systems. Every line item is held to its target value. If one item exceeds its target value, the team must find a way to reduce another line item to offset it, or the design decision must be reconsidered.

Constructability Reviews

HMH conducts continuous constructability reviews (CCR) throughout  preconstruction, Our project manager and superintendent review the progress drawings and provide on-going feedback for any issues that could impact the project. The process draws on our extensive construction knowledge and experience and guarantees that the following questions may be addressed:

• Can the project be built as designed?

• Can the project be built in a more efficient manner for less cost?

• Can the project meet schedule requirements, particularly long-lead procurement needs?

This process reduces the number of change orders and has proven to be a trusted cost-saving tool for many owners.

Building Information Modeling

Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. BIM processes revolve around virtual models that make it possible to share information throughout the entire building industry. These virtual models are embedded with data which, when shared among design team members, greatly reduces errors and makes the process of designing, constructing and operating buildings more efficient. In addition to architectural information, the complete BIM contains all of the building’s information, from wall systems, structural systems, HVAC equipment, plumbing fixtures, door and window schedules, and finishes, right down to the manufacturer, supplier, and square footage of every material specified on the project.

One of the greatest benefits of using BIM is the cost savings to the owner. The majority of the life-cycle cost of a building does not come from the design and construction phase, but from operating the building over 20 to 50 years. BIM has the potential to improve efficiencies throughout the life-cycle of a building. BIM allows the team to analyze building data early on, minimizing changes in the field and expediting the project.

MEP/Trade Specialists

The mechanical, electrical, and plumbing (MEP) systems within a building normally make up a significant portion of the building cost and directly impact the user’s satisfaction with the building. HMH has in-house specialists dedicated to MEP systems.

This portion of our staff is comprised of professionals with design engineering or subcontracting backgrounds. Their function is to act as your advocate in the design and construction of these integrated building systems to ensure they operate as intended.

In addition to standard mechanical, electrical, and plumbing (MEP) systems, your project may include:

• Energy management

• Fire suppression

• Fire alarm

• Security

• Communications

• Specialized and process piping

• Uninterrupted power supply (UPS)

• Specialized lighting and lighting control

• Nurse call

• Life cycle analysis

• Other low voltage expertise

These systems may be extremely complex and are usually interconnected. With our experienced staff, HMH Builders takes the lead to integrate these systems, focusing on performance, results, and owner/end user satisfaction.
