The majority of sources of water infiltration into the building envelope are not directly related to problems with the roof system. To ensure that building owners do not waste valuable time and resources chasing "roof" leaks, proper evaluation of the natural and manmade forces acting on the entire building envelope is essential. Through examination of existing details, third-party moisture surveys, core-cuts*, and, when necessary, destructive testing, CCi identifies the sources of water infiltration and assists building owners in the development of a plan of action.
*As core cuts are taken to verify roof composition and thickness, CCi can also check existing roof systems for asbestos-containing materials (with testing performed by a certified, independent laboratory) that may require special consideration during the design and construction phases of a future project.
Once the sources of water infiltration into the building envelope are identified, an owner's ability to accomplish the necessary repairs must be established. Any design is only as good as an owner's ability to pay; therefore, cost must be the first, and most important, design criteria. CCi identifies repair options, including detailed cost estimates, to assist building owners in making the best use of available funds.
The most effective way of controlling costs is through clear and concise drawings and specifications. CCi uses construction documents as the primary means of ensuring that all potential bidders are giving an "apples to apples" estimate to complete any given project. CCi's experience and direct relationships with manufacturer's, suppliers and contractors are the essential elements in providing a set of construction documents that effectively communicates the design intent.
CCi has experience designing and specifying a variety of roof systems including, fully-adhered EPDM over glass-faced gypsum board and tapered polyisocyanurate insulation mechanically-fastened on a metal deck, fully-adhered TPO over polyisocyanurate insulation set in polyurethane foam adhesive on a concrete deck, slate with copper flashing on plank wood decking, standing-seam metal over ice/water shield on plywood sheathing, elastomeric and urethane roof coatings. CCi has the expertise to design and specify the right roof system for any building.
Throughout the bid process, it is important that any questions that may impact cost and quality are answered quickly and correctly. When possible, CCi recommends a mandatory pre-bid meeting to make sure that bidders understand the entire project scope, including site conditions, which can vary greatly from project to project. A 10,000 sq. ft. roof replacement on a one-story, rural elementary school is much different than a 10,000 sq. ft. roof replacement on a seven-story building in the middle of a congested downtown - even if the roofs are exactly the same.
Additionally, each owner, public and private, have unique procurement requirements that must be understood and properly conveyed to prospective bidders. From federal Davis-Bacon wage requirements to bonding and insurance requirements, each item that may impact cost must be considered prior to the receipt of bids.
Administration of the project during the construction phase is what truly separates CCi from other architecture/engineering firms. Often, necessity demands that a building remain occupied and in service for the duration of the project, adding to the urgency that repairs/replacement be completed as expeditiously as possible. The two principals at CCi, Michael S. Cornett, PE, RRC and Derek B. Cundiff, AIA, RRC are involved in every stage of project CA. Whether it is bi-weekly meetings to review progress and verify pay requests or an unforeseen condition that requires immediate attention and resolution in the field, owners may be assured that their project will have the proper attention from the pre-construction meeting to project close-out.
Quality Assurance Observations (QAO)
Many owners lack the experience, understanding and personnel to manage the day-to-day oversight of a project themselves. In those instances, CCi offers full-time or part-time QAO services in addition to standard Construction Administration services. QAO is not a substitute for the contractor's required supervision of the project and installation in accordance with manufacturer's recommendations and industry standards, rather it is an additional opportunity to verify that the project is progressing forward in conformance with the Construction Documents. As QAO is provided by either a registered professional engineer or a registered architect, both of which are also registered roof consultants, owners know that issues are identified and resolved immediately, as they arise.
