BOULDER WALL NOTES TMIS WORK CONSISTS OF CONSTRUCTING BOULDER WALL STRUCTURES. BOULDER WALLS ARt FOR1tD OF INTtRLOCKING.ORT�STACKED ROCKS WITHOUT REINFORCING STEEL.MORTAR,OR CONCFtTt. CONSTRUCTION RE�UIREMENTS BOULDERS: BOULDERS SHALL CONSIST OF NATURAL STONE WITH VARYING MEiGHTS.AND NQ^'�YAL DtPTHS RANGING iR0`1 IB TO 48 iNCNES. GENERAL�.TME FOLLOWING DEFINITIONS APPLY T�BOULDER WALL CONSTRUCTION�. ' (A)BASE ROCN:THE BASE ROCK IS THE LOWERMOST ROCI(IN THE BOULDER WALL.ANp BEPRS DIRECTLY ON TNE SOIL SUBGRADE. (B)FACING ROCK:THE FACING ROCRS COMPRISE THE BULK OF THE BOULDER WALL ANO AHt STACKED ABOVE THE BASt ROCtt. (C)CAP ROCK'THE CAP ROCK IS THE UPPERMOST ROCK IN THE BWLDER WALL SECT104 ANp'C4PS"THE BDULDER W4LL. BOULDER WALI CONSTRUCTION: (A)BOULDER WALL FOUN�ATION EXCAVATIDN: E%CAVATE A FOUNDATION TRENCM AT LEAST 6 INCHES BELOW THE E%POSED BOTTOM OF TNE WALL,ftU'VNiNG TME FULL LENGTH OF THE PROPOSED BOULDER W4LL.DEEPER EMBEDMENT MAY BE REOUIRED WHERE A TOE SLOPt�i5 PRESENT. E%CAVATE THE FWYDATION TO A MINIMUM WIDTM EOUAL TO THE SPECIFIED BASE ROCR WIDTH. EXERCISE CARE DURING EXCAVATION SO AS NOT TO UNDERMINE THE GARAGE FOUNDATION. STABILITY OF TEMPORARY C11T SLOPES IS TME RESPONSIBILITY OF THE CONTR4CTOR. (B)BOULDER PLACEMENT'. PLACE THE FIRST COURSE OF ROCK(BASE ROCK)ON FIRM,UNYIELDING SOIL WITH FULL CONTA[T BETWEEN TME ROCI(AND TME SUBGRADE. EXCAVATE ANY LOOSE.SOFT OR OTHERWISE UNSUITABLE MATER14L PRESENT AT FOUNDATION GRADE AND kERACE WITH FOUNDATION FILL. COMPA[T THE FOUNDATION FiLL AS NEEDED. AS TXE BOULUER WALL IS CONSTRUCTED,PLACE TME ROCRS 50 THAT THERE ARE NO CONTINUOUS JOiNTS IN EIiMER iHE VERTICAL OR L1TER1l pIRECTION. STOCItPILE A SUFFICiENT NUMBER OF ROCKS TO PROVIOE 1 G00�SEIE[TION fOR PLACEMENT. TO OBTAIN A BETTER FIT,PLACE ROCItS WHICH p0 NOi MATCM TME SPACES OFFERED BY TME PREYIOUS CWRSE IN A DIFFERENT LOCATION. AV010 PLACING ROCI(S WHI[H N4VE SHIPES TH4T CREA7E VOIDS WITH A LINEAR DIMENSION GREATER THAN 8 INCHES. EXCEPi IN ISOLATED CASES,PL4CE E4CH ROCR SO TNAT iT BEARS ON AT LEAST TWO RO[KS BEIOW IT. LOCAlE AT LEAST ONE BEARING POINT A OISTANCE NO GREATER TMAN 6 INCMES FROM TME AVERAGE FACE OF THE BOULDER W1LL. THE ALLOWABLE TOLERANCE FOR BASE kOCR WIDTHS IS 6 IN[HES�.HOWEVER,DO NOT PLACE TWO OR MORE CONSECUTIVE BASE ROCKS WiTM A WIDiM LESS TMAN SPECIiIED ON THE PLANS. SLOPE TNE lOP SURFACE OF E1CH ROCK TOWARDS THE B1[R OF THE BOULOER WALL AT AN INCUNATION OF AT LEAST FIVE(S)DEGREES.TME MINIMUM BWLUFR WALL TMICRN[SS i5 BAStD ON MINiMUM BASE ROCI(WiDTM.AS SPtC�ViED ON Tnt PL4N5,ANU ALLOWAB�E YACE BATTER.TME REOl11RED FpCE BATTER IS 10 UEGREES. SE[URELY PLACE F�CING ROCNS 50 TMAT THE ROCI(S ARE UNABLE TO BE MOVE�WITM A PRY BAR AFTER THE BWIDER WALLIS COMPLETE. (C)VOIOS: WHERE VOIDS WITH 4 MINtMUM OIMENSION OF 6 INCHE$OR GREATER EXIST IN THE FACE OF THE BOULDER WALL,CHINR TME VOi�S WiTH SMALLFR ROCK. (I)IF THERE IS NO ROCK CONTACT WITHIN THE BOUIDER WALL TMI[KNESS,CHINK THE VOID WITH A SMALLER PIECE OF ROCK. (2�CNINKING RDCKS�0 NOT PROVIUE PRIMAHY STRUCTURAL Sl1PPORT FOR THE OVERLYING ROCK. (3)CHINM1ING ROCKS CAN NOT BE HOVED OR REMOVEO BY MAND AFiER BOULDER WAL�IS COMP�ETE.RESET LOOSE CHINKING ftOCKS UNTIL SECURELY PL4CFD OR GROUTED IN PLACE. DO NOT ALLOW GROt1T TO BE RE4�'�LY VISIBLE FROY TME FACE OF BOULDER WALL. (D)FROST REDUCTION: INST4ll TWO IAYERS OF Z-INCM t%TRUDEO POLYSTYRENE AGAINST THE FOUNDATION WALL TO REDUCE TME POTENTIAL VOR fROST HtAVt. StE THE NOTES ON SHEET WI AND ON THE CROSS-SECTIONS FOR ADDITION4L INfORM4TI0N. COVER THE E%TRU�ED POLYSTYRENE WITH A NON-WOVEN GEOTEXTILE(SEE NOTF E BELOW). (E)BOULDER WA��DRAIN4GE: INSTALL THE DRAINAGE AGGREGATE BETWEEN TME BOULDER WALL AND THE EXTRUDED POLYSTYRENE. PLACE DRAINAGE AGGREGATE CONCURRENT WITH BOULDER WALL SO TH4T AT NO TIME i5 EITMER MORE THAN IZ INCMES MIGHER THAN THE OTHER. SEPARATE THE CRUSHED ROCK FROM THE BACIt Oi TME eou�oEas er G NON-WOVEN GEOTE%TILE. OVERLAP THE NON-WOVEN GEOTEXTiLE PT LEAST 12 iNCMES Al ALL SEAMS. TME TOP OF TME�RAINAGE AGGREG4TE SHOULU ALSO BE�CAPPED�WiTM TME GEOT[XTILE. TME DREINAGE AGGREGATE SHOULD BE BETWEEN THE E%TRUDED POLYSTYFtNF AND TMt YiLTtR FABRIC. GENERAL NOTES I. IN PREPARATION OF WA�L DESIGN,SOIL STRENGTH PARAMETERS WERE ASSl1Mt�,UAStO ON A RtVIEW OF SOIL M4PS OF THE AREA. IT IS THE RESPONSIBILITY OF TME OWNtR OR OWNtR'S RtPRtStNTATiVt TO VERiFY THE SOIL STRENGIH PARAMETERS ARE REPRESENTATIVE OF THE SOILS AVAILABLt FOR W4LL CONSTRUCTION. IF THE SOIL STRENGTH PARAMETERS ARE FOIIND TO BE IN[ONSiSTENT WITH THOSF PPOVIDED,THIS�FSIGN i5 NO LONGER VPLID AND IT IS THE RESPONSIBILITY OF THE OWNER OR OWNER'S RtPREStNTATiVt TO NOTIFY VEC 50 THE RETAINING WALL SYSTEM CAN BE REDESIGNED. FAILURE TO NOTIFY VEC MAV RESULT IN FAILUNE OF THE RETAINING WALL. 2. DESIGN SOIL PARAMETERS: P. RETAiNED SOIL: IMPORTE�/ON-SITE SOILS,PMI=28 OEGFEES,GAMMA=125 PCf. B. FOUNDATION SOIL: IMPORTED/ON-SITE SOILS,PNI=28 OEGREES,GAMMA=IZS P[h. 3. ANY E%C4VATION BELOW THE WALL SHOULD HAVE PROPER I:I LATERAL OVERSIZING. E%CAVATiON OVERSIZiNG SMOULD BE MEASU2E0 FRDM THE FRONT TO THE BACK OF THE LOWEST BOULDER. 4. THIS SET OF BOULDER RETAINING W4LL PLANS ARE BASED ON THE SITE SURVEY,PREPAREO BY GRONBERG B ASSOCiATES,INC..DATED 12/24/13. IF OTMER PLANS ARE PROWCEO THAT CONTAIN DIFFERENT iNFORMATiON TNAN THAT REFERENCED,THIS PLAN MAY NEED TO BE REViSED ANO/OR THE W4LL M4V NEED TO BE REDESIGNED. S. LOCATION OF THE BOVIDER RETAINING WALL IN REL4TION TO PROPERTY LINES,UTILITY EASEItENTS,WATERSHED EASEMENTS,OR ANY OTHER TYPE OF EASEMENT$ARE TME RESPONSIBILIT�OF TME OWNER OR TME SITE CIVIL ENGINEER. VEC ASSUME$NO L14BILITT FOR TME LOC4TION OF TME BOUIDER RETAINING WALL,OR iF CONSTRUCTION OF THE PROPOSED BOUL�ER RETAINING WALL ENCROACHES ANY PROPERTY LINES OR EASEMENTS. 6. IT IS IMPERATIVE THAT TME SITE SURVEYING OF TME BOULDER RETAINING WALL BE DONE B'!THE SITE CIVIL EN6INEER OR SURVEYOR ANO MUST BE BASED ON TME PlANS SMOWN ABOVE AND NOT PROFILE PL4NS DONE BY VEC. SURVEYING OF THE BOULDER RETAINING WALL MUST TANE INTO ACCOUNT THE DESIGN BATTER INDICATED ON THE ENCLOSED PLANS AND DETAILS. FAiLIIRE TO TAKE INTO ACCOUNT WALI BATTER FOR BOULDER RETAINING WALL SURYEYING WILL PNODUCE INCORNECT LOCATIONS OF ALL TOP Oi WALL AND SHALL BE CORRECTED AT NO COST TO VEC OR THE BWLDER RETAINING WALL CONTFACTOR. 7. WALL GEOMETRY,LOCATIONS,SLDPES AN�SURCHARGE LOADS FOR THE BOULDER RETAINING WALL WERE ASSUMED FROM TME PROJECT PLANS REFERENCED ABOVE. IF CONDITIONS VARY GREATLY IN THE FIELO FROM THOSE SHOWN ON THIS PLAN,VEC MUST BE NOTIFIED PRIOR TO CONSTRUCTIDN OF THE BDULDER RETAiNiNG WALL TO REVIEW THE DESIGN AND/OR PLANS. MODIFICATION$TO THE DESIGN AND/OR PLANS MAY BE REQUIRE�AFTER TME REVIEW,AND MAY TAM1E UP TO TEN BUSINESS DAY$TO COMPLETE. 8- PLEASE REFER TO THE PROJECT SPECIFICATIONS FOR ADDITIONAL INfORMATION(IF ANY).
