Based on our site visit and discussions on January 9; <br /> 2015, the following is our understanding of the scope of work. <br /> PROJECT APPROACH <br /> The original intent of this document and as described by you in the field was to install steel <br /> spool pieces between the upper frame of the playground shadeport and the existing 10"x10" <br /> steel columns, to raise the frame approximately 18 to 24 inches . In addition, we were <br /> requested to remove any visible rust in the frame, repaint it and have a structural engineer <br /> examine and certify the structural stability of the shadeport frame. <br /> However after further examination and after consulting with a playground shelter <br /> manufacturer concern was raised as to the feasibility and risk of attempting to raise an <br /> existing structure with known rust issues. The frame is composed of 11 sections which are <br /> bolted together with 4 bolts at each joint. Closer examination of these bolts and flanges <br /> shows a significant amount of rust. Based on these conditions I could not find anyone <br /> willing to warrant or certify that this existing frame can repaired to a condition that will last <br /> an extended amount of time. <br /> Our approach therefore, would be to replace the entire shelter frame and canvas on the <br /> existing columns. Additionally; this new frame would be made of powder coated round <br /> members which will reduce the chance of future tearing of the canvas during high winds. <br /> We can also add a canvas sleeve around the member as an extra buffer between the steel <br /> and the canvas. The frame would be configured to raise the overall height of the shelter by <br /> 2 feet. Upon approval, engineering drawings would be provided by the shadeport <br /> manufacturer to be processed through the City's Building Department <br /> 3453 NW 44 Street, Suite 205, Oakland Park, FL 33309 (954)650-4699 Page 1 of 2 <br />
