Initial

2 June 11, 2018 Re: Valve Vault Request for Information Response To whom it may concern, The following comments were raised during the bid process, responses are in bold: 1). On sheet 004 Both linestops are noted to see detail on sheet 007. The only detail found on sheet 007 pertaining to the linestops is detail #4 Concrete Fitting Support Is this the detail being referred to? Yes, Detail 4 Concrete Fitting Support Detail is the detail being referenced. 2). It is our understanding that line stops with bypasses do not come in size on size. For this project I would expect that the 16 linestop would have a 12 bypass. Will a 12 bypass be adequate for the flows this pipe is carrying? Yes, a 12 Bypass should be sufficient for this length of pipe. 3). Just north of the vault the profile shows a deflection of the 16 force main. Is this due to a fitting? If we need to replace a fitting and will there be enough room for a fitting should the location of the 16 Plug valve need to be at Sta and the Check Valve at 2+86? The intention of the plans is to deflect the pipe between the check valve vault and the line stop fitting so a connection can be made. The deflection angle between the proposed profile and connection point confirmed by the vacuum excavate is less than one degree. This falls below the recommended deflection angle for most mechanical joint pipe fittings. A fitting should not be required. 4). Section 9 of the Technical Specifications, Pay Item No. 11 indicates that the new force main shall be PVC. Additionally, plan view on plan sheet 005 indicates PVC pipe. Is it your intention that the piping within the vault be PVC? if so what method or product is approved to create a flange on PVC pipe? The segments of pipe in question have been revised to Ductile Iron Pipe with a plain end to connect to the proposed plug valves and a flanged end to connect to the proposed check valve. Plans, specifications, and bid form have been revised to reflect changes. Items #5 #9 pertain to possible tankering. 5). Is the condition of the existing Cast Iron Pipe known? The condition of the pipe in this area is currently not known. 6). In the event that the pipe ruptures due to its condition prior to having bypassing in place, who s responsible for tankering the sewage? Per Note 5 of the Utilities Section on Sheet 002, The Contractor must prepare an emergency bypass plan for review by the Engineer. Plan should include provisions for the continuation of flow from the City of St. Pete Beach and the City of Treasure Island. The contractor would be responsible for the conveyance of the sewage. However, assuming the rupture of the pipe is caused by the condition of

3 City of St. Pete Beach June 11, 2018, Page 2 the pipe and not by Contractor s negligence, the cost of conveyance would a change order to the contract amount. 7). What is the location of the nearest upstream and downstream valve? The nearest operational upstream valve is at Pump Station No. 1 in St. Pete Beach at the corner of Boca Ciega Drive and 87 th Avenue. The nearest operational downstream valve that the City of St. Pete Beach has on record is at Lift Station 61/Pasadena Master Station at the Intersection of Pasadena Avenue South and Park Circle. The valve at Lift Station 61, could be used to isolate the Treasure Island and St Pete Beach force main, from the other three connections into Lift station 61. 8). Is any other municipality tied into the force main between the upstream and downstream valve, if so can they be diverted or will tankering be required? The City of Treasure Island has two lift stations that manifold through a central force main downstream of the project area. The existing valve vault where these force mains manifold is shown in the Survey along Central Avenue. The valves in this vault are non-operational. The Treasure Island stations and associated valves are located as follows: Treasure Island LS#4 Intersection of Paradise Blvd and Dolphin Drive Treasure Island Master Station Intersection of 108 th Avenue and Gulf Blvd. 9). How much sewer will need to be tankered from all sources should the unexpected happen? The amount of flow would be dependent on the situation and condition of the break or rupture. From the City of St. Pete Beach Model Capacity Report Addendum dated January 19, 2017, during a peak flow event the combined flow from St Pete Beach and Treasure Island could be as high at MGD. However, during average daily flows this is somewhere in the 6-8 MGD range. Items #10 13 pertain to M.O.T. 10). We will need to close one lane of traffic for the installation, will we need to keep two-way traffic on this section of 79 th St. S. requiring flaggers 24 hours per day during the lane closure? Traffic Control Notes listed on the General Notes Page where completed through a Pre-submittal review with the City of St. Petersburg. Any Maintenance of Traffic will have to be finalized with the City of St. Petersburg. Per Note 4 on Sheet 002, Contractor will be required to obtain a City of St. Petersburg Right-of-Way Permit If Contractor plans to use the Right-of-Way within the Treasure Island Causeway they must coordinate with the City of Treasure Island for Right-of-Way Use. 11). Can we detour traffic to the East or West along Causeway Blvd. S. to or from Central Ave. Traffic Control Notes listed on the General Notes Page where completed through a Pre-submittal review with the City of St. Petersburg. Any Maintenance of Traffic will have to be finalized with the City of St. Petersburg. Per Note 4 on Sheet 002, Contractor will be required to obtain a City of St. Petersburg Right-of-Way Permit If Contractor plans to use the Right-of-Way within the Treasure Island Causeway they must coordinate with the City of Treasure Island for Right-of-Way Use.

4 City of St. Pete Beach June 11, 2018, Page 3 12). Can we totally close 79 th St. S between Central Ave. & Causeway Blvd. S. (assuming we can detour) or do we need to keep one lane open? Traffic Control Notes listed on the General Notes Page where completed through a Pre-submittal review with the City of St. Petersburg. Any Maintenance of Traffic will have to be finalized with the City of St. Petersburg. Per Note 4 on Sheet 002, Contractor will be required to obtain a City of St. Petersburg Right-of-Way Permit If Contractor plans to use the Right-of-Way within the Treasure Island Causeway they must coordinate with the City of Treasure Island for Right-of-Way Use. 13). Assuming we need to keep one lane open, is there a preference if it is closed to Northbound or Southbound? Traffic Control Notes listed on the General Notes Page where completed through a Pre-submittal review with the City of St. Petersburg. Any Maintenance of Traffic will have to be finalized with the City of St. Petersburg. Per Note 4 on Sheet 002, Contractor will be required to obtain a City of St. Petersburg Right-of-Way Permit If Contractor plans to use the Right-of-Way within the Treasure Island Causeway they must coordinate with the City of Treasure Island for Right-of-Way Use. 14). Is professional liability insurance required? See response from the City of St. Pete Beach. 15). Per the technical specs 1.14, are test wells required in order to monitor the dewatering discharge? No, test wells are not required in order to monitor the dewatering discharge. 16). Replacement of the stripping and stop bars, does this need to be thermo? Replacement of the stripping and stop bars is required to be thermoplastic. Pay Item No. 16 has been revised to include this information. 17). Does the existing brick walkway at Causeway Blvd need to be removed and replaced or will this area be replaced with asphalt? This existing brick walkway will need to be removed and replaced. This information has been added to the plans, specifications, and bid form have been revised to reflect changes. Pavement Restoration quantities have been revised as well to reflect changes. 18). Note 1 on plan sheet 4, does the entire run need to be excavated or just one spot to verify the existing pipe? At a minimum, the pipe will need to be excavated at both locations where linestops will be placed. 19). Can 79 th St be closed between Causeway Blvd and Central Ave? Traffic Control Notes listed on the General Notes Page where completed through a Pre-submittal review with the City of St. Petersburg. Any Maintenance of Traffic will have to be finalized with the
