About this file

Written by GovTribe AI · May 13, 2026

This document is a complete set of 100% construction documents for G Street Sidewalk Repairs at the U.S. Government Publishing Office located at 732 North Capitol Street NW, Washington, DC 20401. The project, prepared by Gale Associates, Inc. and Dewberry Engineers Inc., encompasses comprehensive repair and renovation work for the sidewalk vault structure and associated site improvements.

The scope of work includes removal and replacement of concrete sidewalks, structural concrete slab repairs with supplemental reinforcement, masonry and brownstone facade repairs with mortar joint repointing, waterproofing system installation, new concrete wear courses with proper slope matching existing conditions, ADA-compliant concrete ramps and stair landings with metal railings, concrete gutters and curbs, removal and reinstallation of existing pavers and granite curbs, and ductwork modifications. Construction details specify Class E concrete per 2020 DDOT Standards (3500 PSI compressive strength, 0-3 inch slump, 4X4 W2.9XW2.9 wire fabric reinforcement, and control joints at 36-inch spacing). The contractor must coordinate manufacturer technical representatives for quality assurance site visits, provide temporary protective structures over through-slab repairs, and schedule work according to owner phasing requirements involving overnight work. Special inspections are required for concrete placement, reinforcing bar installation, and welded connections. The documents include detailed architectural and civil drawings depicting existing conditions, demolition plans, new construction plans, partial elevations, typical sidewalk details, structural slab repair sequences, and stone/mortar joint repair procedures across 25 drawing sheets.

PROVIDE ELECTRIC CURRENT SCANNING TO LOCATE AND MARK EMBEDDED CONDUIT.

5. ALL SPALL REPAIR AREA SUBSTRATES MUST BE THOROUGHLY EXAMINED AFTER COMPLETING THE FINAL SURFACE PREPARATION, TO VERIFY THAT NO ADDITIONAL SUBSTRATE CRACKING OR OTHER STRUCTURAL CONDITIONS EXIST. NOTIFY GALE IF ANY CRACKS OR OTHER DETERIORATED CONDITIONS ARE IDENTIFIED.

6. SPALL REPAIR SURFACE PROFILE MUST ACHIEVE AN ICRI-CSP 8 OR 9. WHERE ACCESS IS LIMITED OR DIFFICULT DUE TO PIPING OR OTHER OBSTRUCTIONS, THEN AN ICRI-CSP 7 SURFACE PROFILE MAY BE

CONSIDERED AS APPROVED BY THE ENGINEER.

7. RUSTED REINFORCING STEEL BARS MUST BE FULLY CLEANED TO BRIGHT, SHINY STEEL TO CONFORM TO SSPC SP11 REQUIREMENTS. WHERE REINFORCING STEEL IS SHOWING SECTION LOSS OF 18" OR 25% OR MORE SECTION LOSS, SUPPLEMENTAL REINFORCING STEEL MUST BE PLACED TO ACHIEVE A MINIMUM OF 20 BAR DIAMETER LENGTH LAPS, AND TIED DIRECTLY ADJACENT TO SOLID BAR SECTIONS THAT DO NOT HAVE SECTION LOSS. ADDITIONAL CONCRETE REMOVAL AND DRILLING WILL BE REQUIRED TO PLACE THE

NEW REINFORCING STEEL.

8. REMOVE ADDITIONAL CONCRETE BEHIND AND AROUND ALL REINFORCING STEEL BARS WHICH ARE CORRODED SO THAT PROPER AND THOROUGH CLEANING MAY BE ACHIEVED AROUND THE ENTIRE BAR. A MINIMUM OF 1” CLEAR, UNOBSTRUCTED SPACE AROUND EACH REINFORCING STEEL BAR MUST BE ACHIEVED ALONG THE FULL LENGTH OF THE BAR IN THE AREA OF THE SPALL REPAIR. CLEAN BARS TO ACHIEVE SSPC-SP11 COMPLIANCE. BARS MUST BE FULLY UNCOVERED TO COMPLY WITH THAT NOTED

HEREIN, IF ANY PORTION OF THE REBAR IS EXPOSED AND IT IS RUSTED.

9. IN ALL CASES, THE EXISTING AND NEW REINFORCING STEEL MUST HAVE A MINIMUM CONCRETE/REPAIR MORTAR COVER OF 1 ½”. NOTIFY THE ENGINEER IF MODIFICATION OF STEEL PLACEMENT OR CONCRETE

THICKNESS IS REQUIRED TO ACHIEVE THIS REQUIREMENT.

10. WITH LARGE OR DEEPER SPALL REPAIR AREAS, WITH DEPTHS EXCEEDING 3 INCHES, IF NO EXISTING REBAR IS PRESENT, OR REBAR GRID IS SEPARATED BY MORE THAN 6 INCHES, THEN THE SUBSTRATE OF THE REPAIR MUST BE PINNED WITH STAINLESS STEEL, 8 MM HELICAL TIES; OR STAINLESS STEEL FULLY THREADED CAP SCREWS WITH HEX HEADS PROJECTING OUTWARD BY 2 INCHES INTO THE MEDIUM OF THE REPAIR. DRILL HOLES FOR THREADED BOLTS (CAP SCREWS) TO 1/8” TO ¼” LARGER THAN THE BOLT DIAMETER. BOLT DIAMETERS SHALL BE 3/16” TO ¼”, AND SHALL BE EMBEDDED 2 INCHES INTO SOLID CONCRETE. USE SPECIFIED STRUCTURAL ADHESIVE TO PLACE THREADED ROD PINS. HELICAL ANCHOR PINS, IF USED, MUST BE DRIVEN USING THE MANUFACTURER REQUIRED DRIVING TOOL AND BIT. PLACE PINS A MAXIMUM OF 8 INCHES ON CENTER, AND TIE 2” X 2” X 14 GAGE HOT-DIP GALVANIZED OR STAINLESS STEEL MESH FROM PIN-TO-PIN. PLACE THE MESH 2” FROM THE BELLY OF THE PREPARED SPALL AREA, WHILE ALWAYS MAINTAINING A MINIMUM 1 ½” OF CONCRETE/REPAIR MORTAR COVER AT THE OUTSIDE

SURFACE OF THE REPAIR.

11. WHEN DRILLING INTO SOLID CONCRETE TO PLACE NEW SUPPLEMENTAL STEEL REINFORCING BARS, DRILL

THE HOLES ¼” LARGER THAN THE BAR DIAMETER. FULLY VACUUM, BLOW OUT (WITH OIL FREE

COMPRESSED AIR) AND BRISTLE BRUSH OUT THE HOLES TO REMOVE ALL DUST, DEBRIS, LAITANCE, ETC.

THE DEPTH OF THE HOLES MUST BE DETERMINED BY THE ENGINEER BASED UPON BAR SIZE, LOCATION, AND NEED FOR DEVELOPMENT. THIS WILL BE DETERMINED ON A CASE BY CASE BASIS. IN NO CASE SHALL THE DRILLED HOLES BE LESS THAN THAT NOTED IN THE PROJECT SPECIFICATIONS UNLESS APPROVED BY THE ENGINEER. IN NO CASE SHALL SUPPLEMENTAL BARS BE LESS THAN #4 BARS, UNLESS OTHERWISE APPROVED BY THE ENGINEER. NEW REINFORCING STEEL BARS MAY BE #5 OR LARGER, DEPENDING UPON THE EXTENT OF REINFORCEMENT CORROSION AND NEED FOR SUPPLEMENTAL STEEL.

BARS EMBEDDED INTO CLEANED DRILLED HOLES MUST BE FULLY ADHERED IN PLACE USING SIKADUR 31

HI-MOD AS MANUFACTURED BY SIKA CORPORATION, OR ENGINEER APPROVED EQUAL.

12. JUST PRIOR TO PLACING THE REPAIR MORTAR AND FORMWORK, THE ENTIRE SUBSTRATE OF THE SPALL REPAIR MUST BE THOROUGHLY CLEANED OF ALL BOND INHIBITING MATERIALS, BROUGHT TO SATURATED SURFACE DRY (SSD) CONDITION WITH POTABLE WATER OR RECEIVE THE BONDING AGENT OR BRISTLE BRUSH APPLIED BONDING SLURRY (ALL AS REQUIRED BY THE MATERIAL MANUFACTURER) AND BE CLEANED REBAR COATED WITH SPECIFIED COATING. APPLY TWO (2) COATS OF THE SPECIFIED REBAR COATING ON CLEANED EXISTING STEEL WITHOUT SPILLING THE MATERIAL ON ANY OTHER SURFACES OR COMPONENTS. DO NOT ALLOW THE COATING TO DRY BETWEEN COATS, NOR DRY PRIOR TO APPLYING THE REPAIR MORTAR. ALL MATERIALS MUST BE APPLIED IN A “WET-ON-WET” CONDITION FOR GREATER

BOND.
