CONTRACTOR QUESTIONS           
           
INCLUDED IN THIS RESPONSE ARE CONTRACTOR QUESTIONS RECEIVED AS OF            
02/11/16.           
           
The following questions were received from plan purchasers. The responses are provided for            
clarification to all bidders in bold after the questions:           
           
Q30:	 Bid Item 8002 reads 48” steel casing (per plans). Please advise. Do we bid 48” or 30”?           
           
A30:	See page number 569 of the new Schedule of Prices provided with this addendum.           
           
Q31: 	Bid Item 8004 54” steel casing; should be 48” steel casing (per plans). Please advise.             
Do we bid 54” or 48”?            
CONTRACTOR QUESTIONS (continued)           
           
A31:	The plans are correct. See revised description of Bid Item 8004 on page 569 of new            
Schedule of Prices and revised Special Provision from WSSC provided with this            
addendum.           
           
Q32:	 Please clarify the location of bid item 8048, Cut & Cap Ex.42” Water. I cannot find it            
on the WSSC plans. Also need a detail of WSSC standard number.           
           
A32:	Bid item 8048 incorrectly references the cutting and capping of an ex. 42-inch            
water.  See revised description of Bid item 8048 on page 576 of new Schedule of            
Prices and revised Special Provision from WSSC provided with this addendum.           
           
In addition, a new item, Bid Item 8134, has been added for the Cutting and            
Capping of the Ex. 16” Water.  Location and detail is provided on plan sheet 341            
(UT-10).           
           
Q33:	Who is responsible for the testing per General Note 23 on plan sheet 332, the cover            
sheet of the WSSC plans, the contractor or SHA?           
           
A33:	Compaction testing is listed as part of the unit price for all items referring to pipe            
installation as stated in the Special Provision “Section 876 – WATER MAIN            
RELOCATIONS”.  Therefore, it shall be the responsibility of the Contractor to            
secure the expertise of a Geotechnical Engineer, licensed in the State of MD, to            
perform the testing to the satisfaction of WSSC’s Inspector per revised Special            
Provision “Section 876 – WATER MAIN RELOCATIONS” provided in this            
addendum.            
           
Q34:	There isn’t a bid item for new sanitary manholes per the spec on page 397.           
           
A34:	Sanitary manholes are paid under Bid Item 8053 as indicated in the Special            
Provision on page 397. See the revised Special Provision “Section 876 – WATER            
MAIN RELOCATIONS” provided in this addendum.            
           
Q35:	 Item 1049, Type E TBET, 65 MPH, was added. There already was an item for this           
work, Item 1043. Please clarify and review quantity cause 1049 is 5 each and 1043 is 4            
each.           
           
A35:	Deleted Bid Item 1049 in this addendum.  Type E TBET, 65 MPH is paid under            
Bid Item 1043, quantity has been revised from 4 to 5 Each in this addendum.           
	           
Q36:	 Item 7020, Construction of Planting Beds was added. There was already and item for            
this work, Item 7016. Please clarify.            
           
A36:	Deleted Bid Item 7016 in this addendum.  Construction of Planting Beds is paid            
under Bid Item 7020.  See revised quantity on page number 568 of the new            
Schedule of Prices provided with this addendum.           
           
CONTRACTOR QUESTIONS (continued)           
           
Q37:	 The answer to Q4 in the addendum says that Item 4011 is deleted by Addendum 1, but            
there isn’t a new page in the schedule of prices that shows that item being deleted.            
Please clarify.           
           
A37:	Bid Item 4011 was deleted as part of Addendum No. 4.             
           
Q38	The answer to Q1, n, says that bid item 3073 is for “Pea Gravel”. Item 3073 is No.2            
Aggregate. Please clarify.           
           
A38	No. 2 Aggregate is correct as shown in Item 3073 description.  As shown on the            
Submerged Gravel Wetland detail sheet 108 (SWM-02), Pea Gravel and No. 2            
Aggregate are identical.  The Pea Gravel referenced in the legend on sheet 121            
(SWM-15) and Sheet 130 (SWM-24) represents No. 2 Aggregate.                 
           
Q39:	The answer to Q1, o, says that the Clay for Core is bid item 3088. In the Schedule of            
Prices, Item 3091 was added by this addendum for the Clay Core.           
           
A39:	Addendum No. 1 letter incorrectly stated The Clay Core is paid under Bid Item            
3088.  The clay core is paid under Bid Item 3091 which was added to the contract            
in addendum No. 1.           
           
Q40:	On page 9 of the addendum, the “Decreased” quantity for bid item 7005 is 128,699 sy.            
In the Schedule of Prices for Item 7005, the quantity is 128,669 sy. Which is correct?            
Please clarify.           
           
A40:	Bid Item 7005 has been revised. See page number 569 of the new Schedule of            
Prices provided with this addendum for updated quantity.            
           
Q41:	On page 13 of the addendum, the “Increased” quantity for bid item 8078 is 144 each.            
In the Schedule of Prices for Item 8078, the quantity is 177 each. Which is correct?            
Please clarify.           
           
A41:	Bid Item 8078 has been revised due to Addendum No. 5 revisions.  See page            
number 581 of the new Schedule of Prices provided with this addendum for            
updated quantity.            
           
Q42:	The answer to Q13 says that item 3076 is to be used for the “unperforated” quantity            
and that item 3057 is to be used for the “perforated quantity. Bid item 3057 is for 6”            
Circular Pipe Underdrain Outlets which is NOT perforated pipe. Please clarify.            
           
A42:	Item 3076 is for unperforated (solid) underdrain pipe used in the SWM Facilities            
for cleanouts and observation wells.  The larger quantity of Item 3057 is            
perforated underdrain pipe use for SWM facilities only, not for the roadway.             
           
           
CONTRACTOR QUESTIONS (continued)           
           
Q43:	 The answers to Q7 and Q8 in Addendum No.1 refer to details that were added to Plan            
Sheet DD-01. This plan sheet was not included in Addendum No.1 and is blank in the            
original set of plans. Please clarify.           
           
A43:	See Plan Sheet 143 of 378 (DD-01) for the Modified Type H Endwall and Modified            
K Inlet details referred to in Addendum No. 1.  This sheet was provided as part of            
Addendum No. 3.           
           
Q44:	In the description of the changes to the Contract Plans on page 19 of the addendum, it            
states that plan sheets 332-353 were revised to add “approver signature”, but the            
remaining utility plans, 354 to 378, not listed in the addendum, were also re-issued as            
part of Addendum No.1. What are the changes to these plan sheets?           
           
A44:	The utility plan sheets start at page number 332 and end at page number 353            
NOT at page number 378, see Index of Sheet (INDX-01).           
           
Q45:	The wage rate decision that is included in the Proposal for this project appears to be old            
and is considerably different than the decision included in the recently advertised            
project PG 6185170. Please provide current wage rate decision that will be applicable            
to this project.           
           
A45:	The wage rate was updated as part of Addendum No. 4.           
           
Q46:	We have been unable to find the 17”x26” HDPE elliptical pipe as shown in Bid Item            
4001. ADS, a HDPE manufacturer, have sent us the attached letter concerning this            
pipe. Their engineers have told them that they cannot make this material. Will the SHA            
consider using elliptical RCP as an alternate to this pipe since there doesn’t seem to be            
an elliptical HDPE pipe?           
           
A46:	The Administration has used this material in previous contracts. The pipe            
material has been manufactured and the structures fabricated, transported and            
installed according to the specifications provided as part of Addendum No. 1.             
           
Q47:	We have reviewed the contract documents and believe that there is geotechnical           
information missing in order to properly price the wick drain scope. We request that            
the MD-SHA release the full geotechnical investigation for the project.Specifically, on            
plan sheets SB-07 to SB-21, we note that no SPT “N-values” were provided on the            
borings. This data must have been collected to establish the consistency/density            
provided. No soil laboratory test results were included in the tables. Again, we have to            
assume some testing was performed in order to complete the design. Lastly, we note            
that numerous borings stopped prior to the specified wick drain tip depth. Although            
some interpretation could be applied between borings it cannot be known with            
certainty the total depth of compressible material. There has to be more information in            
order to specify the wick drains as they are shown on the plans.           
           
           
CONTRACTOR QUESTIONS (continued)           
           
A47:	Soil boring logs and foundation boring test data are added in Addendum No. 5.            
See Appendix A and Appendix B.           
           
Q48:	Please provide WSSC blocking details for the 24” and 30” pipes as the standard details            
from WSSC only go up to 16” pipe size.            
           
A48:	For Blocking Detail for 24” and 30” Ductile Iron Pipe (DIP) see Detail A on Sheet            
343 (UT-12 of 22).           
           
Q49:	How are the removals and abandonments of the existing water lines and appurtenances            
paid? I don’t see any bid items for this work?           
           
A49:	The existing water mains should be abandoned in place.  The abandonment of the            
existing water lines shall be considered incidental to their respective replacement            
line item.  See revised Special Provision “SECTION 876 – WATER MAIN            
RELOCATIONS”.           
           
Q50:	On sheet 13 of 22 of the water main betterment plans note 12A of water mains west of            
MD 5 it says  install a line stop at sta.33+74 on Ex 24” main. I believe that this is an            
existing 16” main. Can you please confirm the pipe size.           
           
A50:	Note 12A incorrectly references Sta. 33+74. Refer to the Pen & Ink Section of this            
letter, the line stop should be set at Sta. 37+74 offset 127’ right. The existing pipe            
in this area is 24” cast iron.           
           
Q51:	Same column on page 13 of 22. Note 13A, can the line stop be placed in the existing            
24” PCCP pipe near station 2+20 by the thrust block?  This would eliminate a            
considerable amount of bypass line needed in note 13D as well as the connection of the            
3 house services. Is there a specific reason that the bypass is set up to be this long &            
connect to the houses that are off the lob limits?            
           
A51:	WSSC does not allow for existing PCCP water mains to be tapped or cut. Line            
stop has therefore been placed on the existing cast iron pipe.  Bypass is required            
since Accokeek Road only source of water is the existing 24-Inch Water connected            
to MD 5.           
           
Q52:	Can we get a plan sheet that shows the exact location of Valve V020 at the Owings            
        Ave/Accokeek Rd intersection? Currently the plan sheets do not cover that area.           
           
A52:	A plan has not been created for this intersection as no proposed water main is            
being installed at that intersection, WSSC’s WERI website provides information            
on how to obtain the existing water plan record.            
           
Q53:	How will the line stops & the bypass system be paid?           
           
           
CONTRACTOR QUESTIONS (continued)

existing conditions. On Brandywine Road between Stations 3620+00.00 to 3622+50.00            
there is a new Fire Station. The entrance of the Fire Station may be in conflict with the            
proposed alignment. Also it appears that the existing condition of the water and sewer            
service for the station may not be reflected on the drawings either. Please verify.           
           
A65:	SHA is aware of the new site development at the Fire Station and will make any            
necessary adjustment during construction.

high.           
           
A75:	The quantity for No. 2 Aggregate is correct.  The Submerged Gravel Wetlands            
required several Aggregate Windows that are 8 inch deep and up to 120’ across            
which account for the large quantity.           
           
Q76:	 On proposal pages 264 thru 266 it seems to indicate that Landscaping, construction            
and materials, as specified in Section 701, 705,708 and 709 are incidental to certain            
Guardrail items. There is no way for the Contractor to know the extent of work that            
will be required pre-bid; please make the above referenced items pay items as they are            
for the Permanent Traffic Barrier end Treatment items as described on pages 267 thru

Original Excavation for Sediment Trap is Incidental to Class 1 Excavation for SWM            
Facility, except for excavation for Forebay and berm which will be paid for as Erosion            
and Sediment Control Original Excavation.” Please confirm that by “incidental” you            
mean that it will be paid for by the CY under the Class 1 Excavation Bid Item.            
Secondly; please provide a detail and or/or limits between the Class 1 area and the            
Forebay area to differentiate the two separate pay items. Please advise.            
           
           
CONTRACTOR QUESTIONS (continued)           
           
A78:	The sediment trap has been designed within the same footprint as the final SWM            
facility.  Therefore most excavation for the sediment trap is being considered            
incidental to the Class I excavation required for the SWM Facility, Bid Item 2003.             
Sediment control original excavation is provided for excavation beyond the SWM            
facility needs at the forebay and berm only.  Also, the cost for any fill that is            
required during the conversion of the facility from sediment trap to the SWM is            
being considered incidental to the erosion and sediment control original            
excavation, Bid Item #3058.  Please refer the SWM plan sheets 107 to 132 (DWG.            
SW-01 to SW-26) for details, profiles, cross-sections etc. which shows the forebay

Q79:	Plan Sheet 185 of 378 Note 2 indicates to “Stabilize Roadway Pavement at the end of            
each work with a minimum of 4” of GAB.”  Please provide additional guidance as to            
what is required; i.e. does this apply once roadway subgrade is reached and prepared? )            
Please advise.             
           
A79:	The 4” of G.A.B., Bid Item 5012, is proposed as Erosion and Sediment Control            
measure for the stabilization of the work area at the end of work day.  Regardless            
of work completed (i.e. whether subgrade is reached or not), the 4 inches of G.A.B            
needs to be laid at the end of each work day to stabilize the area and it is            
Contractor’s responsibility.  In other words, contractor should disturb only the            
area that can be stabilized at the end of each work day with the permanent G.A.B.           
           
Q80:	What type of finish is required for the Pipe Railing (item 6005) – Galvanized or
