FOLLOWING REQUIREMENTS SPECIFIED IN THE SPECIFICATIONS

12) ARE THERE ANY AREAS WHERE THERE MAY BE CONTAMINATED SPOILS ON THIS

PROJECT?

NOT TO OUR KNOWLEDGE

13) WILL THE DOD PROVIDE AN INSPECTOR FOR INSPECTIONS? IF SO HOW FREQUENT

WILL THE INSPECTOR VISIT THE SITE FOR INSPECTIONS (AS NEEDED, DAILY, WEEKELY)?

THIS WILL HAVE BEARING ON PRODUCTION RATES AS TRENCHES CAN’T BE

BACKFILLED UNTIL THE INSPECTOR HAS APPROVED THE PIPE ASSEMBLY AND

INSTALLATION.

INSPECTOR WILL VISIT THE SITE DAILY, USUALLY MORE THAN ONCE A DAY AND WILL BE

AVAILABLE WHEN NEEDED WHITHIN REASON. PROJECT MANAGER WILL ALSO BE AVAILABLE

IN CASE INSPECTOR IS NOT AROUND. WE USUALLY WORK IN CLOSE COORDINATION WITH

THE CONTRACTOR THROUGHOUT THE DURATION OF THE PROJECT.

NO

15) ARE THERE ANY REQUIREMENTS THAT WILL REQUIRE THE WORK TO BE PHASED?

YES, WORK NEEDS TO BE PHASED. REFER TO CONTRACT DRAWINGS AND SPECIFICATIONS

FOR PHASING REQUIREMENTS.

16) UNDER THE SPECS IT STATES ONLY WORK HOURS ARE MON-FRI. WILL WE BE

ALLOWED TO WORK WEEKENDS ON CLEAN UP & BACKFILL & COMPACTION / HAUL OFF

ONCE ALL PIPING HAS BEEN INSPECTED? OR WILL WE STILL BE REQUIRED TO REQUEST

AUTHORIZATION AND BE REQUIRED TO HAVE A INSPECTOR PRESENT

WEEKEND WORK WILL BE ALLOWED IN CASE BY CASE BASIS. REQUESTS ARE REQUIRED

AHEAD OF TIME FOR PROPER COORDINATION. REFER TO SPECIFICATIONS.

AND PLPACED IN SERVICE AT ONE TIME?

REFER TO REQUIREMENTS LISTED ON SHEET G-2 OF THE CONTRACT DRAWINGS.

18) AT THE AREAS OF SODDING OR RE-SEEDING WILL TOPSOIL NEED TO BE PROVIDED

FIRST OR WILL CLEAN SPOILS FROM THE SITE BE ADEQUATE?

NO TOPSOIL REQUIRED. CLEAN EXCAVATED MATERIAL FROM SITE IS ADEQUATE.

19) CAN WE UTILIZE TEMPORAY WATER OFF A EXTG. WORKING HYDRANT TO

REESTABLISH GRASS / VEGITATION?

YES AS LONG AS A BACKFLOW PREVENTER IS PROVIDED FOR THIS PURPOSE.

20) WILL THE DOD PROVIDE AS-BUILT DRAWINGS FOR ALL UTILITIES WITHIN THE AREA

OF WORK?

YES

21) IS THERE ANY AC PIPE THAT WILL NEED TO BE REMOVED ON THIS PROJECT? IF SO

WILL THE DOD HAVE AN AREA FOR US TO DISPOSE OF REMOVED AC PIPE.

NO

22) THE SOW STATES THAT ALL PIPE IS TO BE ABONDED IN PLACE AND ONLY THE ITEMS

ABOVE GRADE WILL BE REQUIRED TO BE REMOVED TO 18” BELOW GRADE ONLY IS THIS

CORRECT?

REFER TO CONTRACT DRAWINGS AND SPECIFICATIONS

20) DOES THIS PROJECT INCLUDE REPLACEMENT OF ANY WATER SERVICE LINES TO THE

BUILDING? DO THE SERVICE LINES NEED TO BE REPLACED OVER THEIR ENTIRE

LENGTH, OR JUST ADJUSTED AND CONNECTED TO THE NEW MAIN?

REFER TO CONTRACT DRAWINGS AND SPECIFICATIONS. MOST SERVICE LINES ARE

REQUIRED TO BE REPLACE UP TO 5’ FROM BUILDING.

21) WILL CATHODIC PROTECTION BE REQUIRED FOR THIS PVC WATER MAIN OR WILL

POLY WRAP OF THE FITTINGS & VALVES BE SUFFICENT? IF SO WILL THERE HAVE TO BE

A CERTIFIED ENGINEERED CATHODIC PROTECTION DESIGN PLAN INCLUDED IN OUR

COST?

REFER TO DRAWINGS AND SPECIFICATIONS. I DON’T BELIEVE THERE IS ANY REQUIREMENT

FOR CATHODIC PROTECTION.

22) WILL THE DOD REQUIRE ANY SPECIAL TREATMENT OF THE CHLORINATED WATER

THAT WILL BE DISCHARGED WHILE FLUSHING OUR MAINS DURING TESTING OR WILL

STANDARD FLUSHING BE ACCEPTABLE?

NO

24) FITTINGS- WILL MEGA LUG RESTRAINTS SUFFICE OR SHOULD WE REFRENCE A

CERTAIN DOCUMENT FOR THRUST BLOCK DETAILS, DEMINSIONS AND BEARING AREAS?

REFER TO SHEET D-1 FOR THRUST BLOCKING REQUIREMENTS. REFER TO CONTRACT

DRAWINGS AND SPECIFICATIONS FOR JOINT RESTRAINTS REQUIREMENTS.

25) FIRE HYDRANT ASSEMBLIES- DETAILS DO NOT MATCH SPECIFICATIONS IT STATES

THAT PUMPER & NOZZLE CONNECTIONS SHALL BE INDIVIDUALLY VALVED BUT DETAIL

DOES NOT INDICATE THIS AND EXTG. FIRE HYDRANTS ARE STANDARD HYDRANTS?

DISREGARD THE REQUIREMENT FOR INDIVIDUALLY VALVED PUMPER AND HOSE

CONNECTIONS AS STATED IN THE SPECIFICATIONS. ALL FIRE HYDRANTS ARE THE

STANDARD TYPE.

28) BACKFILL- IS THERE ANY SPECIAL REQUIREMENT FOR BACKFILL MATERIALS OR

WILL THE EXCAVATED SOILS BE UTILIZED FOR BACKFILL?

EXCAVATED SOIL WILL BE UTILIZED FOR BACKFILL.ALSO REFER TO TRENCH DETAILS IN

CONTRACT DRAWING SHEET D-2.

29) WILL UTILITIES THAT ARE ENCOUNTERED AND OR DAMAGED DUE TO INACCURATE

OR ABSENT MARKINGS BE CONSIDERED A DIFFERING SITE CONDITION?

REFER TO SPECIFICATIONS SECTION 01 11 10 “UTILITIES” FOR REQUIREMENTS

31) IS THERE A CERTAIN WORKING PRESSURE FOR THE WATER SYSTEM AROUND WHICH

WE SHOULD SELECT THE DIMENSION RATION (DR) AND/OR PRESSURE RATING FOR THE

PVC TO BE USED?

REFER TO SPECIFICATIONS SECTION 33 11 00 FOR PIPE TYPE AND THICKNESS

32) DOES THE STATEMENT OF WORK REQUIRE THE CONTRACTOR TO PROVIDE FLOW

RATE DATA FOR THE FIRE HYDRANTS? IF SO WILL THIS BE BASED ON MATERIAL

SUBMITTAL DATA FROM THE MANUFACTURE OR WILL THIS INFO. BE REQUIRED TO BE

MEASURED IN THE FIELD?

YES. FIELD FLOW TEST IS REQUIRED TO RATE HYDRANTS AND PAINT BONNET PER COLOR

SCHEDULE SPECIFIED ON CONTRACT DRAWING SHEET D-4 AND SPECIFICATION SECTION 33

11 00

34) WHEN PRESSURE TESTING AND OR CHLORINATING CAN THE NEW LINE BE TIED INTO

THE EXISTING SYSTEM SO THAT WE ARE TESTING AGAINST VALVES? THIS WILL BE THE

BEST METHOD BECAUSE IT ALLOWS US TO TEST THE FINAL CONNECTION AS WELL.

WE WILL ONLY ALLOW CONNECTING NEW LINE TO EXISTING SYSTEM IF A BACKFLOW

PREVENTER IS INSTALLED BETWEEN OUR SYSTEM AND THE NEW LINE. CURRENT

BLACFLOW CERTIFICATION IS REQUIRED.

35) WE ARE ASSUMING THAT THE MATERIALS FOR THIS PROJECT ARE TAX EXEMPT IS

THIS CORRECT?

AS THE WINNING CONTRACTOR WILL BE WORKING AS A “PRIME CONTRACTOR” RATHER

THAN AN “AGENT” OF THE FEDERAL GOVERNMENT, THE MATERIALS PURCHASED UNDER

AND FOR THIS PROJECT WILL NOT BE TAX-EXEMPT.

36) WILL WE BE ALLOWED TO WORK EXTENDED HOURS AT ANY TIME DURING THIS

CONTRACT? IF SO WILL THERE BE ANY CHARGES FOR OVERTIME HOURS WORKED BY

THE INSPECTOR?

YES, EXTENDED TIME MAY BE ALLOWED IF REQUESTED IN ADVANCE AND AFTER

CONTRACTING OFFICER APPROVAL. WE WISH COULD CHARGE FOR EXTRA HOURS OF

INSPECTION BUT NO THERE IS NO CHARGE.

41) DURING THE DESIGN PROCESS DOES THE EXTG. WATER MAIN HAVE TO BE

EVALUATED FOR PRESSURE AND FLOWRATES AT SERVICES, HYDRANTS OR IS THE

SUPPLY PRESSURE KNOWN TO BE ADEQUATE?

DON’T UNDERSTAND QUESTION. THERE IS NO DESIGN REQUIREMENT AS THIS IS 100%

CONSTRUCTION PROJECT

SUPPLY PRESSURE IS KNOWN TO BE ADEQUATE.

42) ARE THERE EXTG. IRRIGATION COMPONENTS (IE. HEADS, LINES, ETC.) THAT COULD

BE DISTURBED AND WILL NEED TO BE REPLACED AS PART OF THE PROCESS? IF SO WILL

THEY BE MARKED?

REFER TO CONTRACT DRAWINGS FOR REQUIREMENTS AND SPECIFICATIONS SECTION 01 11

10 FOR LOCATING EXISTING UTILITIES. CONTRACTOR IS TO CAREFULLY WORK AROUND

EXISTING STRUCTURES/APURTENANCE/EQUIPMENT TO PRESERVE EXISTING SITE

CONDITIONS AND IF DAMAGE OCCURS THEN TO RETURN IT TO ITS ORIGINAL CONDITION

45) WHAT DURATION OF WATER OUTAGES ARE WE GOING TO BE ALLOWED? WILL TEMP.

BYPASSES BE REQUIRED FOR BUILDINGS IF SO WHICH BUILDINGS?

REFER TO SPECIFICATIONS SECTION 01 11 10 FOR REQUIREMENTS CONCERNING OUTAGES.

DO NOT UNDERSTAND THE QUESTION ABOUT THE BYPASSES FOR BUILDINGS.

46) DOES THE DOD REQUIRE 6’ CHAIN LINK FENCE WITH FABRIC BARRIER AT

LOCATIONS OF THE NEW WATER LINE REPLACEMENT OR WILL TEMP. ORANGE

CONSTRUCTION FENCE WITH T-POST AND OR WARNING TAPE BE SUFFICENT?

TEMPORARY ORANGE FENCE IS SUFFICIENT

47) WILL WATER BE PROVIDED FOR TESTING PURPOSES AND COMPACTION? IF SO IS

THERE GOING TO BE A FEE OR CHARGE FOR WATER?

REFER TO SPECIFICATIONS SECTION 01 11 10. ALL UTILITIES ARE MADE AVAILABLE TO THE

CONTRACTOR AT NO CHARGE. HOOKUPS AND REMOVALS ARE CONTRACTOR’S

RESPONSIBILITY.

48) IS THERE ANY GEO TECH REPORTS FOR THIS PROJECT SITE? WHAT IS THE SOIL

CONDITION WILL WE ENCOUNTER ANY ROCK?

NO GEO REPORT. SOILS ARE MOSTLY CLAY. NO KNOWN ROCK LAYER WITHIN PROJECT

EXCAVATION DEPTHS

49) WILL THE DOD CONSIDER ADDITIONAL DAYS TO COMPLETE THE PROJECT MORE

THAN 112 CALANDER DAYS? THE 112 CALANDER DAYS INCLUDES DESIGN, REVIEW AND

APPRORVAL THAT DOES NOT LEAVE MUCH TIME FOR THE ACTUAL INSTALLATION AND

TESTING OF THE NEW WATER DISTRIBUTION SYSTEM.

DO NOT UNDERSTAND THE QUESTION. WHERE DO 112 DAYS COME FROM? PERFORMANCE

PERIOD FOR THIS PROJECT IS 450 DAYS. THERE IS NO DESIGN REQUIREMENT AS THIS IS

100% CONSTRUCTION PROJECT

50) WILL THE DAVIS BACON HEAVY HWY SCALE BE USED FOR THE INSTALLING

CONTRACTOR?

NO. THE DAVIS BACON ACT WAGE DETERMINATION FOR THIS PROJECT WILL BE “HEAVY”,

PLEASE SEE THE FOLLOWING LINK FOR DESCRIPTIONS OF THE DIFFERENT TYPES OF

CLASSIFICATIONS: http://www.wdol.gov/usrguide/sectionc.aspx#c4b

51) THE 22” CASING REQUIRED IS NOT A COMMON SIZE AND IS VERY DIFFICULT TO FIND.
