INC. —y 41-tic:turnr`. 4%4 clzallical & Ch,il Di` ineerin Con-sidtivits PROJECT OVERVIEW: This project is to replace.the entire roofing system for the Aquaiiique Condominium Association building at the subject address. The current roofing system is a BUR system which is failing due to several reasons. Radiographic (Nuclear) moisture surveys have shown the vast majoriq, of the roofing system to be wet. Decent repairs to the NE coder of building also revealed the roof to be soaked. Plow long the roof has been wet is net known. Referring to the attached figure, the baseline replacen-i6it system will be a Sopreina / Nemo Torch Down system over llghtwelglit concrete. ' The eciuiiiinent room and other raised roofs Avill also be a torch down system. Penthouse Particulars: `.There are six (6) penthouse (PH) 'units that have access to their own recreational areas of the roof and they currently have concrete pavers. pour of the PIS decks have hot tubs. It is anticipated that the other two Ply owners will ills€all hot tubs in the future, so plans are to provide a built-up curb for all six PH hot tubs. The actual area of payers for each PH is gyDroxiilaately 700 SFT Crr_roQ11zl�..4 2^40 §P totaT) The new roofing system provides for PH owners having mud set pavers of their choice installed in those areas, over the lightweight concrete. Also. in the areas of hot tubs. we will pour standard 2500 nsi concrete as a base and raised curb. Privacy Fencing: Approximately 120 ft of privacy fencing and gating will need to be replaced. Although not verified, it has been reported that the existing fence posts are recessed into the structural deck. Please Note this is a POST TENSION deck. so extreme care must be taken before anv 17enetrations are made into the deck. GPR examination will be reauired unless the new penetration is exactly the same as the existing ParapetWalls: The baseline project will not include the parapet walls, BUT we are asking for optional pricing to include the parapet walls. The baseline intent is to extend the new roofing system 8" up on the parapet walls with riglets and turn bars. The option will be to cover the parapet wads with a modified system up and over the caps, terminating on the outside edge of the' cap. 751 Northlake Boulevard, Suite 2C # Nordi Palm Beach, Florida 33408 Office (561) 84 4060 f Facsimile (561) 8441--1001 www.struc-engmeers.com AQUANIQUE CONDO ROOFING Page 3 of 36 STRUcruRAL.
