CONCRETE REPAIR NOTES:

1. THE SPECIFICATIONS ARE AN INTEGRAL PART OF CONCRETE REPAIR AND SHOULD BE USED AS PRIMARY DIRECTIONS FOR REPAIRS. THE SECTIONS AND DETAILS ON THESE S20X DRAWINGS ARE SUPPLEMENTARY AND DESCRIPTIVE ONLY AND THE SPECIFICATIONS HOLD PRIORITY.

2. THE TWO SETS OF CONCRETE REPAIR PLAN DRAWINGS DESCRIBE THE LOCATIONS OF VARIOUS

ITEMS OF DAMAGE. THE DAMAGE IS LOCATED AND QUANTIFIED ON THE TABLES ON THOSE SHEETS AS “SURVEYED” QUANTITIES.

3. THE “SURVEYED” QUANTITIES WERE SUMMED BY CATEGORY AND INCREASED TO ALLOW FOR

PLANNED REPAIR DETAILS AND IS PROVIDED IN THE BID TABULATION. A FURTHER “ALLOWANCE” WAS ALSO PROVIDED AS A SEPARATE LINE ITEM IN THE BID TABULATION TO PROVIDE A BUDGET CONTINGENCY.

4. PAYMENT FOR REPAIR WILL BE BASED ON ACTUAL QUANTITIES MEASURED DURING THE REPAIR

PROCESS, REPORTED BY THE CONTRACTOR AND APPROVED BY THE ENGINEER. SPACE IS PROVIDED ON THE DRAWING TABLES FOR NOTES. OFFICIAL MEASUREMENTS FOR PAYMENT WILL BE RECORDED BY THE CONTRACTOR ON THE PROVIDED EXCEL SPREADSHEET AND VERIFIED BY THE ENGINEER AS A DAILY/WEEKLY AGREED PROCEDURE.

5. EACH REPAIR IS NOTED WITH A “PRIORITY” NUMBER. THE PRIORITY NUMBER SYSTEM IS

EXPLAINED ON DRAWINGS S301 AND S401 AND IDENTIFY WHICH REPAIRS ARE TO BE MADE AND WHICH ARE DEFERRED. SOME REPAIRS MAY BE ADDED OR REMOVED BASED ON FURTHER OBSERVATIONS.

6. PRIORITY 3 REPAIRS MAY BE ADDED TO THE WORK IF FUNDING IS AVAILABLE AND DETERMINED

APPROPRIATE. 7. PRIORITY 4 REPAIRS MAY BE CHANGED BY ADDITIONS OR REMOVALS IF IT IS DETERMINED THAT

SOME STRUCTURE IMPROVEMENTS ARE NOT TO BE ACCOMPLISHED. REMOVALS WILL BECOME PRIORITY 1 OR 2. ADDITIONS ARE NOT EXPECTED BUT MIGHT BE THE RESULT OF MOVING A PLANNED ROADWAY.

8. CONCRETE SHALL BE EDGE CUT, REMOVED, ROUGHENED AND FULLY PREPARED PER

SPECIFICATIONS. 9. REINFORCING STEEL SHALL BE ADDED PER THE SPECIFICATION OR AS DIRECTED BY THE

ENGINEER. MEASUREMENT QUANTITIES SHALL BE PROVIDED ON THE SPREADSHEET AND PAID FOR AS USED. WELDING AND OTHER DETAILS ARE CONSIDERED PART OF THE REINFORCEMENT BID ITEM AND NOT PAID SEPARATELY.

10. REPAIR MATERIAL SHALL BE MACHINE APPLIED CONCRETE/MORTAR AS SPECIFIED. HAND

APPLIED CONCRETE/MORTAR REPAIRS ARE ALLOWED AS DESIRED BY THE CONTRACTOR BUT EXPECTED TO BE USED IN ONLY HARD TO REACH AREAS.

11. SLAB SOFFIT REPAIRS SHALL BE AS SHOWN ON DETAILS A AND B. REINFORCING REPAIRS, IF

REQUIRED SHALL BE AS SHOWN ON DETAILS R1, R2 AND R3. 12. BEAM AND GIRDER REPAIRS SHALL BE AS SHOWN ON DETAILS E & F ON DRAWING S204.

REINFORCING REPAIRS, IF REQUIRED, SHALL BE AS SHOWN ON DETAILS R1, R2 AND R3 ON DRAWING S203.

13. WELDED WIRE FABRIC SHALL BE 2 X 3 ‐ #12 X #12 GALVANIZED. SECURE IN PLACE BY WIRE TIED

TO EXISTING REINFORCEMENT AT NOT MORE THAN 18” CENTERS. WHERE EXISTING REINFORCEMENT IS NOT ADEQUATE TO SECURE FABRIC, CONTRACTOR SHALL PROPOSE PREFERRED APPROACH SUCH AS POWDER DRIVEN ANCHORS.

14. CRACK REPAIRS SHALL BE AS DIRECTED IN THE FIELD AND AS DETERMINED BY FURTHER

EXPLORATORY INVESTIGATION PAID FOR BY A BID ITEM ALLOWANCE. A. STRUCTURAL CRACKS WITHOUT SIGNIFICANT REBAR CORROSION SHALL HAVE EPOXY‐

INJECTED CRACK REPAIR PER SPECIFICATIONS AND DETAIL D. B. NON‐STRUCTURAL CRACKS SHALL EITHER BE CONSIDERED FOR FUTURE REPAIR AS

PRIORITY 3 OR SHALL BE SEALED PER SPECIFICATION “GROOVE AND SEAL” METHOD AND PER DETAIL C.

C. IN ADDITION TO PROVIDING MEASUREMENT FOR PAYMENT BY THE PROVIDED SPREADSHEET, THE CONTRACTOR SHALL MAP PRIORITY 3 CRACKS THAT ARE POSTPONED FOR FUTURE REPAIR.

Question:

There are ten encasement beams in the original contract that have been changed to a reinforced concrete

beam detail in response to Power’s RFI 106. As the work has proceeded we have noted that 7 of the 10 beams

have an angled concrete encapsulated steel beam that intercepts the beam we are required to repair. These

beams are not shown on the drawings and result in additional demolition, rebar splices, and formwork in order

to complete the contract repairs. We feel we have the information to complete these repairs, but the additional

time required should be at extra cost.

Suggestion:

Answer: Date Answered: 11/29/2012

Please proceed with repair. Specified new rebar in beam needs to continue through the angled beam

Connection in Marginal Wharf at East

End



Sketch References:

Question:

There are ten encasement beams in the original contract that have been changed to a reinforced concrete

beam detail in response to Power’s RFI 003. The repair requires dowels 7 EA #8 dowels at each end of the

beam. When the East end of the new concrete beams intercepts a pile we have good concrete to dowel into.

However the beams being encased are spaced approximately 5’ on center and the piles are approximately 15’

on center. The intermediate beams between piles join a steel encased concrete beam similar to the one being

repaired. This is unreinforced concrete which is not efficient for the dowels to be placed.

At these beam locations we could weld the bar to the perpendicular North-South beam flange or web in place

of dowels?

As a secondary option, should the dowels at the East end be installed with hooks placed through the web of

the perpendicular beam? This would allow us to pour the beam and create a beam pocket on the East side of

the North-South intercepting beam. This beam pocket could be reinforced or doweled up into the slab above to

tie the two beams together?

Suggestion:


Please see attached sketch-Richard Rhee

Drawing ClarificationStructuralPier 30-32 – Reinforcement Details in RFI

111 and 112



Sketch References:

Question:

RFI 111 gave reinforcement details for a new reinforced concrete

beam. The reinforcement will exist both where the bottom flange

is intact and where it is deteriorated. We assumed that the bottom

bars would be installed below the bottom flange of the steel beam

to provide containment for the concrete beam. RFI 112 indicates

that the bottom bars of the new reinforced beam are placed above

the bottom flange of the steel beam leaving the concrete below

unreinforced.

We would propose to install the reinforcement below the flange of

the existing beam. At the East end of the beam where we need to

connect to an existing steel beam running North South addressed in

RFI 112, we could install “Z” shaped bars to lap the new steel. The
