- Description
- This amendment is being issued to EXTEND the solicitation due date to read July 9, 2008 at 3:00 PM Question 1. Amendment #1 answer #1 stated the price for the seed project should go on line item 0006 on form 1442. What is the location of the Alternate #1 pricing? Answer 1. The Alternate #1 pricing should be at the bottom of the bottom of page 4 which is Division Description. Question 2. Revised drawing A1.2 general note #1 states after demo to replace, repair or level the floor area. Because of the amount of area involved and the three repair options along with the different cost of those repair options could an allowance or a square footage be given for bidding purposes? Answer 2. General Note #1 on the latest revision to Drawing A1.2 (Revision 2) in part reads “PACKAGE BE CONTRACTOR SHOULD REMOVE EXISTING UNDERLAYMENT AND/OR ADD ADDITIONAL LEVELING COMPOUND TO CREATE A SMOOTH TRANSITION ACROSS ENTIRE FLOOR AREA.” The contractor must decide whether it will be easier and/or less costly to remove some of the existing topping material or to install additional topping to achieve the uniform floor level to comply with the requirement Question 3. Drawing A1.1 Demo note 1A states to remove existing masonry wall. I could not locate symbol 1A on the drawing. Please Advise. Answer 3. There may not be any masonry walls to be removed in this portion of the project. Note 3 indicates where new door openings are to be cut into masonry walls. Question 4. Spec Section 03532 Concrete Floor Topping was one of the revised spec. sections that was issued. The drawings do not show any work at the elevator 3 location. The spec. does not really give a scope of work for this area. Please provide a drawing, scope of the work or some direction of the amount of area to receive concrete topping. Answer 4. The wrong specification was provided; a revised specification Section 03532 – Hydraulic Cement Underlayment is to be used. The reference to elevator 3 has been deleted and the technical requirements have been revised SECTION 03532 - HYDRAULIC CEMENT UNDERLAYMENT PART 1 - GENERAL 1.1SUMMARY A.This Section includes hydraulic-cement-based underlayment for use below interior floor coverings. 1.2SUBMITTALS A.Product Data: For each type of product indicated. B.Shop Drawings: Plans indicating substrates, locations, and average depths of underlayment based on survey of substrate conditions. C.Qualification data. 1.3QUALITY ASSURANCE A.Installer Qualifications: Installer who is approved by manufacturer for application of underlayment products required for this Project. PART 2 - PRODUCTS 2.1HYDRAULIC-CEMENT-BASED UNDERLAYMENTS A.Underlayment: Hydraulic-cement-based, polymer-modified, self-leveling product that can be applied in minimum uniform thicknesses of 1/8 inch (3 mm) and that can be feathered at edges to match adjacent floor elevations. 1.Products: Subject to compliance with requirements, provide one of the following: a.Ardex; K-15 Self-Leveling Underlayment Concrete. b.Bonsal, W. R. Company; Self-Leveling Underlayment. c.ChemRex; Sonneborn Sonocrete Sonoflow. d.Conspec, a Dayton Superior Company; Conflow. e.Dayton Superior Corporation; LeveLayer I. f.Dependable Chemical Co., Inc.; Skimflow ES. g.L&M Construction Chemicals, Inc.; Levelex. h.MAPEI Corporation; Ultraplan 1. i.Maxxon Corporation; Level-Right. j.US Mix Products Company; US SPEC Self - Leveling Underlayment. 2.Cement Binder: ASTM C 150, portland cement, or hydraulic or blended hydraulic cement as defined by ASTM C 219. 3.Compressive Strength: Not less than 4100 psi (28 MPa) at 28 days when tested according to ASTM C 109/C 109M. 4.Underlayment Additive: Resilient-emulsion product of underlayment manufacturer formulated for use with underlayment when applied to substrate and conditions indicated. B.Aggregate: Well-graded, washed gravel, 1/8 to 1/4 inch (3 to 6 mm); or coarse sand as recommended by underlayment manufacturer. 1.Provide aggregate when recommended in writing by underlayment manufacturer for underlayment thickness required. C.Water: Potable and at a temperature of not more than 70 deg F (21 deg C). D.Reinforcement: For underlayment applied to wood substrates, provide galvanized metal lath or other corrosion-resistant reinforcement recommended in writing by underlayment manufacturer. E.Primer: Product of underlayment manufacturer recommended in writing for substrate, conditions, and application indicated. F.Corrosion-Resistant Coating: Recommended in writing by underlayment manufacturer for metal substrates. PART 3 - EXECUTION 3.1APPLICATION A.Prepare and clean substrate according to manufacturer's written instructions. 1.Treat nonmoving substrate cracks according to manufacturer's written instructions to prevent cracks from telegraphing (reflecting) through underlayment. 2.Fill substrate voids to prevent underlayment from leaking. B.Concrete Substrates: Mechanically remove, according to manufacturer's written instructions, laitance, glaze, efflorescence, curing compounds, form-release agents, dust, dirt, grease, oil, and other contaminants that might impair underlayment bond. 1.Moisture Testing: Perform anhydrous calcium chloride test, ASTM F 1869. Proceed with installation only after substrates do not exceed a maximum moisture-vapor-emission rate of 3 lb of water/1000 sq. ft. (1.36 kg of water/100 sq. m) in 24 hours. C.Wood Substrates: Mechanically fasten loose boards and panels to eliminate substrate movement and squeaks. Sand to remove coatings that might impair underlayment bond and remove sanding dust. 1.Install underlayment reinforcement recommended in writing by manufacturer. D.Metal Substrates: Mechanically remove, according to manufacturer's written instructions, rust, foreign matter, and other contaminants that might impair underlayment bond. Apply corrosion-resistant coating compatible with underlayment if recommended in writing by underlayment manufacturer. E.Nonporous Substrates: For ceramic tile, quarry tile, and terrazzo substrates, remove waxes, sealants, and other contaminants that might impair underlayment bond, and prepare surfaces according to manufacturer's written instructions. F.Adhesion Tests: After substrate preparation, test substrate for adhesion with underlayment according to manufacturer's written instructions. G.Close areas to traffic during underlayment application and for time period after application recommended in writing by manufacturer. H.Coordinate application of components to provide optimum underlayment-to-substrate and intercoat adhesion. I.At substrate expansion, isolation, and other moving joints, allow joint of same width to continue through underlayment. J.Apply primer over prepared substrate at manufacturer's recommended spreading rate. K.Apply underlayment to produce uniform, level surface. 1.Apply a final layer without aggregate to produce surface. 2.Feather edges to match adjacent floor elevations. L.Cure underlayment according to manufacturer's written instructions. Prevent contamination during application and curing processes. M.Do not install floor coverings over underlayment until after time period recommended in writing by underlayment manufacturer. N.Remove and replace underlayment areas that evidence lack of bond with substrate, including areas that emit a "hollow" sound when tapped. O.Protect underlayment from concentrated and rolling loads for remainder of construction period. END OF SECTION 035416 Question 5: Is attachment 1 to SF 1442 to be completed and turned in with the bid or is that document due after the award? Answer 5: All documents are to be submitted on the closing date. The Technical Proposal must be submitted separate from the Price Proposal.
