Over 140 Years in the Industry

A Strong Foundation Begins with Quandel.

We strive to earn your trust every day, and we pride ourselves on partnerships and our growing list of repeat customers. Our success is defined by the long-lasting relationship we share with our clients long after the project is complete.

​We treat each project as our most important job. An executive of the company is personally involved with every project we undertake to address our clients’ interests effectively, ethically, and economically. Because our approach is comprehensive, each project is managed with the maximum combination of experience, technical knowledge, and management representation, regardless of scale, schedule, or complexity.

We are dedicated to creating dynamic learning environments that provide opportunities for students to collaborate and inspire  intellectual and physical activity and social connections. We keep current with educational trends and supplement our project experience with independent research initiatives and post-occupancy evaluations. In addition to building instructional and research spaces that are responsive and adaptable to the program needs, we also place a great deal of attention on “in-between” spaces to foster social interaction and the cultural attributes of the academic community. We realize the value of a close working relationship as we collaborate with you and the design professionals to refine and monitor program scope, cost, schedule, and quality. We construct facilities that serve the needs of your students for decades to come.


The hospitality industry focuses on creating positive and memorable guest experiences and building popular destinations. Hotel, restaurant, and entertainment venue construction work should not get in the way of that. We have experience meeting the needs of hospitality clients and executing multimillion-dollar renovations and additions with minimal interruptions and fast-tracked operations where needed. We do this with our in-house team and working with trusted subcontractors. Careful management of our construction sites allows us to deliver confidence and quality with each project.


​Having constructed millions of square feet in industrial projects, our construction professionals take on complex projects regardless of circumstances or scale. From distribution facilities to processing plants, we understand the challenges clients face. With a hands-on construction approach, we simplify complexities while reducing costs and provide clients with peace of mind that their facilities will be completed to their specifications. From large site development projects to existing facility expansions, our team focuses on achieving the best possible outcome for clients and their businesses.

Multi-Family / Mixed-Use

From market-rate multi-family housing to PHFA tax credit housing, we construct living spaces where your clients come home to relax, recharge, and live their lives. Whether planning a traditional townhouse complex or mixed-use apartment building, our experience and trade contractor network will provide value to you as we develop budgets, establish project phasing, and identify product alternatives that achieve your vision. Our experience extends to providing construction services for renovations, additions, new construction, and other types of work for commercial residences, including older and historical buildings repositioned for multi-family housing.

Non-profit / Community

We believe that every person should have access to well-built spaces where they can thrive. From churches to shelters to youth centers, we partner with the community and non-profit associations to build spaces where people can grow spiritually, become healthier, be better educated, and increase economic mobility. We care about the lasting impact on partner communities.


Every school building program sets out to achieve a mission. This  mission aims to establish a foundation that enables students to gain the skills necessary to become productive and successful adults. Likewise, We realize that a winning project begins with a team approach. From planning through occupancy, we will work with you and your design professionals to refine and monitor the scope, cost, schedule, and quality of your project, which will serve the needs of your students for decades to come.


Our firm has a special understanding of religious construction and experience in working with clergy, building committees, and congregations. We approach the construction of places of worship with reverence and apply our liturgical understanding to the design of worship centers to enhance the action of your worship practices. Our construction considers the liturgy, how worship is conducted and applies the function of the programming requirements throughout the building.


Our work in retail spaces includes a range of projects across many types of businesses and construction phases. We perform buildouts, renovations, additions, and new construction projects on everything from grocery stores to small boutique storefronts. With the experience of our skilled, attentive staff, and trusted subcontractors, we know how to keep foot traffic moving and finish the project according to a schedule that works for your business. Tight deadlines are well within our capabilities, and we work within a broad scope for reliable, quality retail construction.

Senior Living

Our senior living construction professionals are capable of building facilities that meet the needs for independent living, assisted living, memory care, and skilled nursing, as well as active adult communities. We build to the location, lifestyle, and services required for your campus. We understand the physical, emotional, and aesthetic needs of seniors. Relying on this knowledge, we provide solutions that address regulatory requirements and that your residents are proud to call home. Our experience creates positive results for senior living owners, operators, and developers throughout the industry by understanding their businesses and the needs that come along with them.

Quandel ConstructionVirtual Design & Construction

Keeping Projects on Track
See digital models of your buildings and job sites before construction even starts. Our Virtual Design and Construction (VDC) team focuses on creating a collaborative environment with our clients to deliver customized and innovative construction solutions. We use the latest technology in our VDC process to streamline the delivery of our projects in an integrated and Lean approach. This approach allows for enhanced communication, efficient collaboration with our trade partners, and the effective use of Building Information Modeling (BIM) expertise for overall project coordination.

BIM is a digital representation of a structure’s physical and functional properties. This technology enables us to design a project virtually, track progress, optimize processes, minimize waste, and validate installations. This allows for improved quality as well as a decrease in risk as workflow becomes more efficient. By using BIM during the design process, we can identify conflicts, address coordination issues, and create clear metrics against the program’s goals.

We work together with stakeholders to determine optimal outcomes. We sit down with your team and develop a BIM execution plan for the project. We approach BIM as a process to mitigate risks. During this process, we use digital tools to create virtual models of buildings. The model acts as a single source of information containing existing condition details, proposed designs, and coordinated work plans during construction. These digital models are then evaluated before ground is broken, allowing project teams to optimize building construction. Through 3D digital modeling, stakeholders can see and address issues before they ever become a reality, preventing costly mistakes during construction. By integrating forward-thinking designers and contractors into the BIM process, conflicts are detected and corrected quickly saving you money and time.

Alternative Delivery Methods

A Better Way to Build
Choosing the best delivery method for your project does not have to be a difficult task. Depending on your project needs, desire for involvement in decisions, and risk tolerance, there is a delivery system that is right for your project. Some considerations when determining your project approach include:

  • Is it a strictly cost-driven approach?
  • Is it a schedule-driven approach?
  • Who will hold the risk?
  • Who will ultimately be accountable?

A linear design-bid-build process where the Owner selects an architect/engineer to fully document the project criteria and design prior to bidding. The lowest responsive and responsible general contractor (single prime) is awarded the contract. Bids are based on the original plans; any changes to the plans and specifications are administered by change order above and beyond the bid.

Construction Manager At-Risk
A contractor is hired through a best value selection process before or during the design phase. The Owner, architect, and construction manager are a collaborative team from planning through construction with a primary emphasis on integrating design and construction. The construction manager provides a guaranteed maximum price (GMP). The construction manager solicits competitive bids from prequalified subcontractors holding the subcontracts for construction.

Construction Manager Agency
A construction manager is hired as an Owner’s agent through a qualifications-based selection process during the design phase. The construction manager provides estimates before or during design, assists with bidding, and coordinates prime contractors during construction. The Owner bids and holds the construction contracts. The construction manager agent is paid based on hourly rates or a fee. This is in addition to the general contractor or prime contractor fee.

An Owner contracts and collaborates with a single design-builder for the project. The design-build team includes the architect, engineer, and construction manager. The design-build team complete the design and a guaranteed maximum price (GMP) is provided. The design-build team solicits bids from prequalified subcontractors and holds the subcontracts for construction.

Integrated Project Delivery
The integrated project delivery (IPD) process allows the Owner, design, and construction team to use information, such as incorporating building information modeling, in an integrated environment, to increase efficiency and support new ways of working. Based on Lean construction principles, IPD is the reliance on knowledge integration that adds value through maximizing efficiency and collaboration of those involved. Given that IPD encompasses collaborative processes that rely on the collective expertise of the extended project stakeholders (including designers, builders, subcontractors, and owners), the effects of design decisions can be easily understood, increasing the level of project success.

Quandel ConstructionPreconstruction Services

First Step in Planning
We help our clients know what to expect and when by providing a step-by-step roadmap for getting the project done. Early preconstruction services and project controls lay the foundation for a successful project.

Quandel ConstructionProject Planning

Planning a construction project starts way before plans are drawn.
We lead, manage, and execute a construction project from design to building completion. Our impact on a project’s outcome is greatest at the planning stage. Our ability to optimize results starts with a defined construction plan incorporating scope and costs for informed decision-making. Led by our preconstruction manager, the team will work to understand the owner’s vision and objectives for their project. Starting with initial project phasing, we collaborate with the design team and the Owner using our experience to evaluate various phasing and sequencing options, including the people, resources, and budget for the project. Leadership drives the process. After assessing project variables, we create a comprehensive project plan that clarifies programmatic and budgetary objectives.

Our team strives to understand the final desired project outcome and define the steps required to achieve that outcome during project planning. In this step, we analyze and select the method and the order of work for a specific project. We identify construction activities, develop the construction schedule, and plan out the team structure. From working with a client on finding the property to develop to creating a visual sketch or building information model of the conceptual design to project close out, we are a trusted and valued partner to our clients. Proper planning is a roadmap for success, reduces the potential for change orders, contains cost overruns, and limits liability.
