Answer: The waste designation included in Base Bid Item 5 is “PCB, petroleum, and metals-contaminated concrete slabs as EPA/TSCA regulated PCB Remediation Waste (≥50 ppm)”

Question: O the unit prices what if the area is lagger than 1500 square feet we should have a larger containment, and you should be telling us how its going to be constructed.

Answer: If a containment greater than 1,500 square feet is required to conduct out of scope work the cost for which will be determined through the change order process. Determining means and methods for constructing such a containment would be the contractor’s responsibility.

Question: In the specs it shows we need a state sign but there was one on site do we need another state sign?

TEST PITS AND OTHER EXPLORATORY ACTIVITIES WERE COMPLETED TO

OBSERVE THE EXISTING CONDITION OF THE CONCRETE SLABS AND

FOUNDATION COMPONENTS. NOTABLE FINDINGS FROM THESE

ACTIVITIES ARE LISTED BELOW FOR INFORMATIONAL PURPOSES.

1. THE GREEN SHADED BASEMENT SLAB AREA WAS OBSERVED TO BE EIGHT TO

NINE INCHES THICK, ON AVERAGE. FORMER EQUIPMENT LOCATIONS WERE

IDENTIFIED TO HAVE SLABS AS THICK AS 15 INCHES.

2. A SUBSTANTIAL AMOUNT OF CONCRETE PIERS AND OTHER CONCRETE BLOCKS

AND DEBRIS WAS IDENTIFIED BENEATH THE GREEN SHADED BASEMENT AREA

SLABS.

3. THE TAN SHADED ELEVATED SLAB AREA WAS OBSERVED TO BE EIGHT TO TEN

INCHES THICK, ON AVERAGE.

4. MULTIPLE CONCRETE PARTITION WALLS, SUPPORTS, AND OTHER FEATURES WERE

OBSERVED BENEATH THE TAN SHADED ELEVATED SLAB AREA.

5. A SECOND CONCRETE SLAB WAS OBSERVED APPROXIMATELY NINE FEET BENEATH

MOST OF THE TAN SHADED ELEVATED SLAB AREA. THE TOP OF THE SECOND SLAB

WAS IDENTIFIED AT THE SAME APPROXIMATE ELEVATION AS THE GREEN SHADED

BASEMENT AREA. THIS SECOND SLAB WAS NOT IDENTIFIED BENEATH THE

BUILDING 3 BASEMENT.

6. THE VOID SPACE BETWEEN THE ELEVATED SLAB AND THE LOWER SLAB WAS

OBSERVED TO BE FILLED WITH SANDY FILL MATERIAL INTERMIXED WITH

VARIOUS DEBRIS. SOME SPACES / FORMER ROOMS MAY REMAIN AS OPEN

UN-FILLED VOID SPACES.

7. FOOTINGS WERE OBSERVED AT THE BASE OF PERIMETER AND INTERIOR WALLS.

THESE FOOTINGS WERE OBSERVED TO BE VARIOUS SIZES AND EXTENDING FROM

12 INCHES TO FOUR FEET BENEATH THE WALLS.

BASED ON ANALYTICAL RESULTS REPORTED FOR

POST-REMOVAL SAMPLES.

2. ALL CONTAMINATED CONCRETE AND SOIL SHOWN ON

DRAWINGS REM-1 AND REM-2 MUST BE REMOVED PRIOR TO

STARTING DEMOLITION AND PROCESSING OF NON-REGULATED

MASONRY DEBRIS. ENGINEER WILL NOTIFY CONTRACTOR ONCE

ALL CONTAMINATED MATERIAL IS REMOVED.

3. AREAS NOT DESIGNATED FOR DISPOSAL AS REGULATED

WASTE WILL BE MANAGED AND DISPOSED OF AS

NON-REGULATED MASONRY DEBRIS UNDER THE BASE

CONTRACT OR CRUSHED AND USED AS BACKFILL AS AN

ALTERNATE BID ITEM.

4. PITS A AND B ACCUMULATE SEVERAL FEET OF STANDING

POTENTIAL SEQUENCE FOR SLAB, FOUNDATION, AND SOIL REMOVAL. CONTRACTOR MUST INCLUDE THESE STEPS IN THE CONSTRUCTION SCHEDULE SUBMITTAL SPECIFIED IN SECTION 01325 SCHEDULING OF CONSTRUCTION.

CONTRACTOR MAY SUGGEST AN ALTERNATIVE SEQUENCE IN THE SCHEDULE SUBMITTAL. IT IS EXPECTED THAT

SOME TASKS WILL OVERLAP FOR EFFICIENCY PURPOSES.

1. REMOVE CONTAMINATED CONCRETE FROM AREAS AND LIMITS IDENTIFIED ON DRAWING REM-1. ENGINEER WILL COLLECT POST REMOVAL CONCRETE SAMPLES TO DETERMINE IF THE REMEDIAL OBJECTIVE HAS BEEN MET. ADDITIONAL

REMOVAL MAY BE REQUIRED BASED ON RESULTS OF THESE SAMPLES.

2. REMOVE CONTAMINATED SOIL FROM AREAS AND LIMITS IDENTIFIED ON DRAWING REM-2. ENGINEER WILL COLLECT POST REMOVAL CONCRETE SAMPLES TO DETERMINE IF THE REMEDIAL OBJECTIVE HAS BEEN MET. ADDITIONAL

REMOVAL MAY BE REQUIRED BASED ON RESULTS OF THESE SAMPLES.

3. REMOVE NON-CONTAMINATED ELEVATED CONCRETE SLAB TO EXPOSE UNDERLYING FILL MATERIAL LOCATED BETWEEN THE ELEVATED SLAB AND UNDERLYING SECONDARY SLAB. EXCAVATE TEST PITS AS DIRECTED BY ENGINEER TO ASSESS FILL MATERIAL FOR POTENTIAL ON-SITE REUSE AND/OR DISPOSAL REQUIREMENTS. ENGINEER WILL IDENTIFY AREAS

OF FILL MATERIAL FOR ON-SITE REUSE AND/OR DISPOSAL.

4. REMOVE AND SEGREGATE FILL MATERIAL FROM BENEATH THE ELEVATED SLAB AS DIRECTED BY ENGINEER.

NON-CONTAMINATED FILL MATERIAL MAY BE USED TO BACKFILL SOIL EXCAVATION AREAS. CONTAMINATED FILL

MATERIAL MAY BE STOCKPILED AND/OR LIVE LOADED FOR DISPOSAL.

5. DEMOLISH AND REMOVE CONCRETE PARTITION WALLS FROM BETWEEN THE ELEVATED AND SECONDARY SLAB AREAS.

ENGINEER WILL ASSESS CONCRETE FOR POTENTIAL CONTAMINATION AND IDENTIFY WHAT CONCRETE CAN BE SET

ASIDE FOR POTENTIAL CRUSHING AND ON-SITE REUSE AND WHAT WILL BE DISPOSED.

6. ENGINEER WILL ASSESS SECONDARY CONCRETE SLAB FOR POTENTIAL CONTAMINATION AND IDENTIFY WHAT CONCRETE CAN BE SET ASIDE FOR POTENTIAL CRUSHING AND ON-SITE REUSE AND WHAT WILL BE DISPOSED.

CONTRACTOR MAY BE DIRECTED TO CRACK SLAB TO PROMOTE DRAINAGE AND LEAVE SOME OR ALL SLAB IN PLACE.

7. DEMOLISH, MANAGE, REMOVE, AND CRUSH FOR ON-SITE REUSE OR DISPOSE OF REMAINING NON-CONTAMINATED

SLABS AND FOUNDATIONS.

8. BACKFILL FOUNDATION OPENINGS.

SESC NARRATIVE

THE CITY OF WATERBURY IS PROPOSING TO REMOVE THE CONCRETE SLAB AND BUILDING FOUNDATIONS LOCATED AT 170

FREIGHT STREET IN WATERBURY, CT.

THE PROJECT WILL INCLUDE THE DEMOLITION AND REMOVAL OF THE EXISTING SLABS AND FOUNDATIONS, EXCAVATION OF

CONTAMINATED SOIL, AND ABANDONING ANY FORMER BUILDING UTILITY SERVICES.

THE DISTURBED AREAS ARE PROPOSED TO BE RESTORED WITH BACKFILL AND GRADED TO DRAIN SIMILAR TO EXISTING

DRAINAGE PATTERNS.

THE PROJECT IS PROPOSED TO BE PERFORMED IN A SINGLE PHASE, IT IS ANTICIPATED THAT APPROXIMATELY 3.13 ACRES

WILL BE DISTURBED.

ANTICIPATED PROJECT CONSTRUCTION START: FALL 2025

ANTICIPATED PROJECT CONSTRUCTION END: SPRING 2026

SOIL EROSION AND SEDIMENTATION CONTROL MEASURES SHALL CONFORM TO THE STANDARDS OUTLINED IN THE CONNECTICUT DEPARTMENT OF ENERGY AND ENVIRONMENTAL PROTECTION (CTDEEP), "2002 CONNECTICUT GUIDELINES FOR

SOIL EROSION AND SEDIMENT CONTROL", LATEST REVISION.
