HomeMy WebLinkAboutF101 FOUNDATION PLANGENERAL FOUNDATION NOTES MISCELLANEOUS The structure and its several parts have been designed for the in-service loads only. The methods, means, procedures, and sequences of construction are the responsibility of the Contractor. The Contractor shall take all necessary precautions to insure safe working conditions and maintain the integrity of the structure during all stages of construction. The adequacy of the design of temporary bracing, shoring, etc. is the contractor's responsibility. The bracing design for cast -in place concrete, tilt -up concrete, precast concrete and masonry walls is the complete responsibility of the Contractor. Temporary bracing for walls shall be adequate to resist the forces imposed during construction. Bracing for a wall shall not be removed until all supporting levels or units have been erected and the concrete of the supporting levels has attained the specified compressive strength (F'c). In the case of walls supporting soil, the braces shall additionally remain in place until the backfilling procedures have been completed. FOUNDATIONS Foundation excavations shall be made to plan elevations. Foundations are to bear on firm, undisturbed soil. The soil conditions beneath foundations shall then be inspected by a qualified Geotechnlcal Engineer. Where unacceptable soils occur, excavate and replace with an acceptable engineered fill. Foundations and soils related work shall be performed in accordance with 2012 International Building Code minimum required design calculations. Design Net Soil Bearing Pressures: Spread Footings: 1,500 psf Continuous Wall Footings: 1,500 psf Foundation conditions noted during construction, which differ from those described in the geotechnical report shall be reported to the Architect, Structural Engineer and Geotechnical Engineer before construction is continued. CONCRETE Reinforced concrete has been designed in accordance with the current'Building Code Requirements for Structural Concrete' (ACI 318). Mixing, transporting, and placing of concrete shall conform to the latest edition of the 'Specifications for Structural Concrete for Buildings' (ACI 301). Concrete in the fallowing areas shall consist of natural sand fine aggregate and normal weight coarse aggregates conforming to ASTM C33, Type 1 Portland Cement conforming to ASTM C1 50, and shall have the fallowing compressive strength (F'c) at 28 days: Footings and Mats: 3,000 psi Slabs -on -Grade: 4,000 psi (700 psi flexural) Retaining Walls, Curbs, Sidewalks and Slabs Exposed to De-icers: 4,000 psi (6%+1%entrained air by volume) Concrete (flowable fill or lean concrete) used as fill under footings or as backfill behind walls shall consist of natural sand fine aggregate, Type 1 Portland Cement conforming ASTM C150 (50 pounds minimum), and type C or F Fly Ash, and have a compressive strength (Ec) at 28 days of 75 psi. Concrete compressive strength tests shall be performed in accordance with A5TM C39. Copies of the test results shall be forwarded directly to the Structural Engineer. One set of specimens shall be taken for each day's pour of appreciable size and for each 250 cubic yards in accordance with the latest edition of ASTM C31. Each set shall include one specimen tested at 7 days, 2 specimens tested at 28 days and one specimen retained in reserve. This set of test cylinders shall be protected against freezing. Slump tests shall be made prior to the addition of plasticizers. Where concrete is placed by pumping methods concrete for test cylinders and slum tests shall be taken at the point of final placement Y P P Adjustment of slump by adding water to the mix at thejob site shall occur as follows. Adjustment shall be made one time only with a maximum of 2 gallons of water per cubic yard such that the specified slumps and water / cement ratios are not exceeded. The concrete shall be mixed after the addition of water one minute per cubic yard to a maximum of 5 minutes. Protect the concrete surface between finishing operations on hot, dry days or any time plastic shrinkage cracks could develop by using wet burlap, plastic membranes or fogging. Protect concrete deck at all times from rain, hail or other injurious effects. Construction joints shall be prepared by roughening the contact surface in an approved manner to a full amplitude of approximately 1/4 inch leaving the contact surface clean and free of laitance. Use of construction joints at locations other than those indicated on the drawings shall be submitted to the Structural Engineer for approval. Principal openings in the structure are indicated on the contract documents. Refer to the architectural, mechanical, electrical, and plumbing drawings for sleeves, curbs, inserts, etc. not herein indicated. Openings in slabs with a maximum side dimension or diameter of 10 inches or less shall not require additional framing or reinforcement, unless noted otherwise. The Structural Engineer shall approve the location of sleeves or openings in structural members. The Contractor shall verify the location of sleeves, openings, embedded items, etc. and shall insure that they are in place prior to the placement of the concrete. The Contractor shall submit for review by the Structural Engineer a mix design for each proposed class of concrete. Mix designs shall show weight proportions for components of the mix. The Contractor shall not vary from the mix design without the approval of the Structural Engineer. No Fly Ash is permitted in the concrete for this project. CONCRETE SLABS -ON -GRADE: Slabs on grade shall be constructed in accordance With the latest edition of the'Guide for Concrete Floor and Slab Construction' (ACI 302.1 R). In addition to the specifications noted elsewhere, the normal weight concrete for flatwork shall conform to the following: Minimum Cement Content: 5 sacks / cyd Maximum Water Cement Ratio by Weight: 0.48 Maximum Slump Prior to Addition of Plasticizers: 3 inches Maximum Slump if Plasticizers are not used: 4 inches Minimum cement content shall be 6 sacks/cyd and max w/c ratio shall be 0.43 for Curbs, Sidewalks and Slabs exposed to de-icers. Slabs -on grade shall be placed to achieve the following minimum tolerances: Overall Values: Ff = 40 FI = 30 Local Values: Ff-35 FI-25 Place concrete in a mannerso as to prevent segregation ofthe mix. Floating and troweling operations shall not occur until the concrete has lost surface watersheen or all free water. Do not sprinkle free cement on the slab surface. Provide curing of concrete slabs immediately after finishing using a sprayed on liquid curing compound. Other methods may be used with the Structural Engineer's approval. Reference specifications. Subgrade modulus for slab on grade design: 140 pi RELEASED FOR CONSTRUCTION Subject to compliance with all regulations of State and Local Codes e City of Carmel �VII�W'lBwMiRpA/4L_ DATE: \ 11/14/19 CONCRETE REINFORCEMENT: Reinforcing bar detailing, fabricating, and placing shall conform to the latest edRio n of the following standards: '5pe cificatio ns for Structu ral Concrete Buildings' (ACI 3 01 ) and'ACI Detailing Manual' IS P66).

Horizontal bars in walls or grade beams shall be bent at corners and intersections in such a way that continuity is provided through the joint. Separate corner bars of the same size and spacing as the horizontal reinforcing may be substituted for the bent portion of the continuous bars. The Concrete Contractor shall prepare detailed working or shop drawings to enable fabrication, erection and construction of the work in accordance with the drawings and specifications and shall submit one reproducible copy and one blue line copy to the Structural Engineer for approval. These shop drawings will be reviewed for design concepts expressed in the contract documents only. The Contractor shall be responsible for all dimensions, accuracy, and fit of work.
