Architectural Design

Below we have outlined a description of architectural services offered by Celli-Flynn Brennan. For your project, the scope of actual services will depend upon your specific needs and the project type.

Existing Facilities Survey & Evaluation

At the beginning of an addition or renovation project, we provide Existing Facilities Survey and Evaluation services. Facilities Surveys are typically conducted with our MEP (Mechanical, Electrical and Plumbing) and Structural Engineering consultants. During this phase of a project, we document existing conditions and evaluate the building’s structural integrity and functionality of building systems.

Programming & Visioning Workshops

Prior to actually designing a building, we provide Architectural Programming services. Programming is the research and decision-making process that identifies the scope of work. During programming, data is gathered and analyzed so that the design is based upon sound decisions and efficiencies are gained by avoiding redesign. The outcome of this process is a written document, which may be accompanied by graphics, that describes the building’s general purpose, room requirements and sizes, special facilities, and preliminary cost estimates for implementation.

The most successful projects are those in which donors, board members, administrators, faculty, staff, students and communities hold a stake in the process at the beginning. Therefore, we use an interactive workshop process to make sure that these parties are involved in programming and visioning prior to the design effort.

Conceptual Design

Conceptual Design is the beginning of the architectural effort and often occurs through a series of workshops. During these on-site sessions with stakeholders, we develop a series of conceptual alternatives which address the form of the building as well as the site, building envelope, sustainable strategies, project schedule and phasing. We also develop a preliminary cost model. With workshop participants, we then evaluate each alternative and select one conceptual design option. When this process is complete, an updated program, site diagrams, system narratives, conceptual plan, three-dimensional massing model and a cost model are delivered to the client.

Space Planning

Once the building program and conceptual design are established, space planning begins. During Space Planning room adjacencies, circulation, configuration, stacking are studied and planned.

Code & Local Ordinance Review

At the beginning of every project, our architectural team conducts a review of local building codes in order to understand if there are specific issues that must be addressed in that location. During technical and design reviews, which occur at regular intervals during design, designated members of our team conduct reviews to be sure that the design is advancing according to all national, state and local codes. Understanding building code issues is paramount in the development of new buildings or building renovations in order to ensure public health, welfare, sanitation and safety. Specific issues that we address include:

  • Fire protection
  • Life safety
  • Means of egress
  • Security
  • Accessibility
  • Sanitation
  • Traffic and parking
  • Requirements for earthquake, hurricane, tornado and flood resistance
  • Energy provisions
  • Installation methodologies
  • Building occupancy classifications
  • Room sizes
  • Construction materials

Schematic Design & Design Development

During Schematic Design alternative floor plans, exterior designs, structural and MEP systems, and lifecycle cost analyses are developed in accordance with the general design parameters set forth during Conceptual Design and Space Planning. A preferred schematic alternative is selected based on reviews involving client representatives and the design team. During Design Development, this alternative is refined to the level where the structure can be built. Plans, wall sections, three-dimensional models and other drawings are developed. This effort is supported by state of the art computer technology, utilizing the latest generation of software programs for BIM (Building Information Modeling), estimating, scheduling and document control.

Construction Documents

Based on the client’s approval of Design Development drawings, we prepare Construction Documents which are the working drawings and specifications that will be used to construct the building. In this phase we also assist our clients in the preparation of bidding forms, the conditions of the contract, and the form of agreement between the owner and contractor.

Cost Estimating

We design all of our projects using Building Information Modeling (BIM), a three-dimensional modeling software. Because the model contains accurate and real data about building materials, systems, construction methods and so on, we are able to automatically develop quantity take-offs that can be used to generate cost estimates. This can be done at any time, but we typically provide a preliminary cost estimate during Conceptual Design and then a more accurate estimate once Construction Documents (CDs) are 50% complete and then again once CDs are 90% complete. We constantly update our vast database of cost information to ensure the accuracy of these estimates. For large and complex projects, we may engage an outside cost estimating consultant.

Assistance in Bidding & Negotiation

Assistance during Bidding and Negotiation is a continuation of our efforts to provide excellent service to our clients. During this phase of the project, competitive bids or negotiated proposals are sought as the basis for awarding a construction contract. We prepare the advertisement or invitation to bid, instructions to bidders, the bid form, and the proposed contract documents. We then manage the procurement process, including contractor vetting and award.

Construction Administration

During Construction Administration, we coordinate all construction activities, directly managing the construction process with regular, on-site supervision. We conduct meetings, answer questions and RFIs (Requests for Information) from the contractor, issue addenda and clarify information.

Engineering & Consultant Coordination

We bring most value to our clients when we focus on our expertise – architecture. Therefore, instead of providing engineering services in-house we use an outside team of engineers and specialty consultants, with whom we have worked on hundreds of projects. During all phases of design and construction, we coordinate these consultants, which may include:

  • Structural Engineering
  • Mechanical Engineering
  • Electrical Engineering
  • Plumbing & Fire Protection Design
  • Site/Civil Engineering
  • Landscape Architecture
  • Topographic Surveying
  • Geotechnical Engineering
  • Telecommunications Design
  • Food Service Design
  • Acoustics Design
  • Audio-Visual Systems Design
  • Lighting Design
  • Wayfinding & Signage Design
  • Building Systems Commissioning
