Career & Technology Education Addendum - Custom Presented by Mike Bell AWILL Career & Technology Education Module 14 The purpose of this module is to introduce the group to more complex custom items. This is being presented as an addendum to the base bid to experience an addendum in a “real life” model.
Receipt of an Addendum Drawings of the Reception Desk Additional renderings to represent the desk visually This Addendum will consist of a Custom Reception Desk. This will include finishing and installation. The Presenter will ask for a new table captain - How many wheels in the driveway/garage? - New table captain will come up to receive the addendum items. Packet will consist of: Addendum Drawings and (3) renderings.
Custom: Reception Desk Understanding the Processes Step by Step Material Take-off Building the Item on paper A Complete Labor Take-off Total Material and Labor Presenter does an introductory outline of what tasks will need to be completed.
Custom: Reception Desk Understanding the Processes Additional Engineering and Drafting Required Spend enough time in plant to familiarize yourself with how custom items are built Better yet – work with your custom people and follow a project through your plant The more you understand the processes, the better estimate you will generate With custom items it is very important to understand all of the processes required to produce and install the custom items. This starts with Engineering. Often it means that the estimator will add additional engineering time to their bid. Next, it is important to know how custom items are built. We will be following these processes throughout this module. Spend some time on the plant floor. Go out to the jobsite and see how these items are incorporated into a project. The more you understand these processes, the better you can estimate the time and material required to build, finish and install custom architectural woodwork.
Custom: Reception Desk Understanding the Processes Everything starts with engineering. The shop drawing process is necessary for submittal purposes, but is absolutely essential to determine how a custom item will be built. If engineering is left to the shop floor, not only will production time be reduced to “head scratching time”, but accuracy and predetermined joinery will be reduced to convenient solutions. Quite often custom items need to integrate with other material, other jobsite conditions, specific required openings and any combination of appliances and equipment. Without due diligence in the Engineering process costs can skyrocket and disasters can thrive and multiply. Engineering
Custom: Reception Desk Understanding the Processes Once a custom item is released for fabrication, proper layout by a top custom journeyman is essential to start the project in the right direction. Laying Out
Custom: Reception Desk Understanding the Processes Part by part, the machining process begins by cutting out the panel stock. Cutting Panel Stock
Custom: Reception Desk Understanding the Processes Intricate components are taken to CNC machining centers for radius cut-out and various machining steps. Without a CNC machining center, additional hours are required to either build various jigs or simply cut out with band saws and machine with handheld routers. Machining out Parts
Custom: Reception Desk Understanding the Processes Die walls are a common component of much of the custom architectural woodwork. The assembly of die walls is a common practice in a custom department and it is fairly easy to learn to quantify the hours required. Assembling Die Walls
Custom: Reception Desk Understanding the Processes After the die walls are assembled, they are skinned out with laid up panels, laminate clad panels or any other substrate and surface material. Skinning out Walls
Custom: Reception Desk Understanding the Processes Once the walls are complete, the journeyman can begin to assemble the unit, fitting and assembling parts as required. Assembling Parts
Custom: Reception Desk Understanding the Processes Once a custom item has been assembled, if finishing is needed, quite often a disassembly process must be accomplished to take the item apart for component finishing. Prior to finishing is an extensive sanding procedure that must be carefully executed to prepare the parts for custom finishing. Sanding and Finishing
Custom: Reception Desk Understanding the Processes Further disassembly may be required in order to prepare the item for shipping and delivery. Protective wrapping quite often is required and could add additional costs to producing this item. Careful loading can only be done by spending the time required. You might consider this in your estimated time and material recap. Disassembling and Shipping
Custom: Reception Desk Understanding the Processes With proper engineering, machining and fabrication proceeding the installation process, things should fit together nicely on the jobsite. The better coordination done prior to installation, the more contained the installation hours will be. Installation
Custom: Reception Desk Step by Step Material Take-off With a thorough understanding of the processes required, begin a step-by-step material breakdown. List all material needed to build this item.
Custom: Reception Desk Building the Item on paper The estimating process for custom items essentially is building the item on paper.
Custom: Reception Desk A Complete Labor Take-off Each labor operation must be listed and hours to perform can be derived from the Cost Book.
Custom: Reception Desk Total Material and Labor A compilation of all material costs and all hours needed by operation equals your dollar costs.
Time is given for the companies to do a thorough break down of material and labor for this desk. Presenter does a summary of what tasks have been completed and reviews the material required and labor operations that will be necessary. Presenter informs attendees to place totals with their bid.
