Typical Pilecap Notes
All pilecaps to have top curtain of #5 @ 12"cc mineach way, 3" clear from top of pilecap, uno.Contractor and job inspector shall notify StructuralEngineer of any pile not driven in its proper locationas shown on drawings so that corrective measuresmay be taken if required. Piles driven more than 3"out of proper location shall be replaced with newpiles, as reqd, at no cost to owner.Where wall pours across the top or into the sideof pilecaps, provide dowels from pilecap with 48bar diameters embedment at same size andspacing as wall reinforcing. Projectdowels 48 bar diameters above pilecap.Bottom mat reinforcing at pilecaps to be 6" clearfrom bottom of cap w/ 90° standard hooks ea.end. Place longitudinal bars on bottom uno.Concrete pilecap 28 day strength to beF' = 4000psi.If pile must be cut off, use the following procedures:
a) if pile is cut off below point where minimum dowelembedment into sleeves at top of pile can not beachieved, a minimum of 4'-0" of strand shall extendinto pilecap.b) if pilecap is cut at point where minimum dowelembed into sleeves at top of pilecap can bemade, exposed strands to remain and providedowels in grouted sleeves as shown in .
If pile cut off exceeds maximum cut-off length, pileductile tie reinforcing must be evaluated andaccepted by Structural Engineer or a new pile mustbe driven.
See for typical pilecap section.
For pile extensions see detail
All pile caps shall be poured against undisturbednative soil or engineered fill.

Pile Notes:
1. Use 1/2"ø ASTM 416-68 gr.270"lowlax" strands; f' = 268,000p.s.i. A# 0.153"
2. Initial tension: 28,900 #/strandEffect: Prestress: 960 p.s.l.
3. Concrete strength:f'c = 4,000 p.s.i. @ transferf'c = 6,000 p.s.i @ 28 days
4. Design load capacities:
Typical 14"Ì PilesDL+LL = 200kDL+LL+S = 300kLateral = 15kTension = 150kMax moment = +550 in-kipsFlexural length = 45'-0"(includes 10 feet for maximum cutoff)
5. Pile Design Criteria:Combine axial load & bending:1) 1.4D2) 1.2D+1.6L+0.5Lr3) 1.2D+0.5L+1.6Lr4) 1.2D+0.5L+1.0E5) 0.9D-E
Pile manufacturer is to provide pile design calculations signed bya registered Professional Engineer. Provide additional mildreinforcing as required to provide required capacity. Spirals shownare a minimum and subject to manufacturer's design.
6. Placement of piles shall conform to the soils reportand under the continuous observation by a representative of that firm.Final pile depths to be determined in the field by the GeotechnicalEngineer.
7. Pile extension detail, if required, to be submitted to and approvedby Structural Engineer.
8. Provide driving follower to protect steel and strand extendedfrom pile typical.

Pinned Pile Moment Diagram
Designs herein are based on the use of 18" diameter augered pressure groutedpiles. The pile length is expected to be as noted in details & .Actual depth of piles is subject to field recommendationsby the Geotechnical Engineer.
Pile grout requirements:f'c = 4500 psi minimum compressive strength @ 28 daysFly ash content: 25-30% maximum cement replacementSee also spec section 31 63 16
Design load capacities for 16"Ø piles:DL + LL = 200 kips allowable (1.0D + 1.0L)DL + LL + seismic = 550 kips ultimate (1.29D + 0.5L + ΩE)uplift = 300 kips ultimate (0.9D - ΩE)flexural length = 10 ftlocation of M = 4 ftNote: Piles not relied upon for lateral load reistance.Pile reinforcing shown on sheet is adequate toresist 1/4" deflection at pile head.
Pile Design Criteria: Governing Load Combinationsa) D+L (allowable)b) 1.29D + 0.5L + ΩE (ultimate)c) 0.81D - ΩE @ tension piles (ultimate)
Combine axial load & bending in design of pile.Design shall be performed in accordance w/ 2010CBC, Section 1810.
Pile design and installation shall conform to the project soils report:#59633-06-1 by Geocon Consultants Inc. dated September 9, 2011 with continuousobservation by a representative of that firm. Pile design calculations, signed by alicensed structural engineer in the State of California, shall be submitted for reviewprior to contruction of piles.

Provide testing on piles per the requirements of the specifications and 2010 CBCSection 1808.3.3. Additionally, pile load testing shall conform to therecommendations of the solis report. Submit a test pile plan showing the location ofthe test piles for approval prior to the commencement of testing. The test programshall represent all loading conditions on the site. Per 2010 CBC Section 1810.3.3.1.2,at least one pile shall be tested in each area of uniform subsoil conditions asdetermined by the geotechnical engineer. The construction of productionpile/foundations will not be allowed until the tests for pile capacities have beencompleted and the test results have been accepted by Geotechnical & StructuralEngineers.

Typical Pile Cap Notes1. All pile caps to have top curtain of #6 @ 12"cc min EW, 3" clear from top of pilecap, typ. uno.2. Contractor and job inspector shall notify Structural Engineer of any pile not installed in its proper location as shown on drawings, so that corrective measures may be taken if required. Piles not installed within tolerances per specifications, shall be corrected, as required, at no cost to owner.
3. Where wall pours across the top or into the sideof pile caps, provide dowels from pile cap same sizeand spacing as wall reinforcing. Embed wall dowels tobottom layer of pile cap reinforcing per
Dowel projection into wall above perspecific sections at each condition.
4. Bottom mat reinforcing at pile caps to be 8" clearfrom bottom of cap w/ 180° standard hooks ea. end.Place longitudinal bars on bottom uno.
5. Minimum compressive strength of pile cap concrete isto be f'c = 5000 psi @ 28 days. See specs for type G concrete.
6. See for typical pile cap detail.
7. All pile caps shall be poured against undisturbednative soil or engineered fill per soils report.
8. No dobies allowed on top of piles.
