            B.         Thoroughly inspect construction area and accessible or observable bordering areas and any nearby areas designated by the Owner or Engineer, for rodent activity and sanitation deficiencies weekly throughout the duration of this Contract and in accordance with the work schedule.  Maintain inspection records in the manner described in Paragraph 3.7 below.

 

            C.         Plan the control program and allocate resources based on survey and inspection data and as acceptable to the Owner.

 

3.3       APPLICATION FOR RODENT CONTROL

 

            A.        Apply rodenticide in strict accordance with EPA-approved label directions and the Rules and Regulations of the Massachusetts Department of Food and Agriculture.  Maintain records of all bait placements in the manner described in Paragraph 3.7 below.

 

            B.         Where appropriate, especially for surface placements of rodent baits, use properly secured and tamper-resistant bait stations consistent with EPA regulation.  Individually number and properly identify all bait stations.

 

            C.         Surface Applications

 

                        1.         Initial Surface Baiting

 

                                    Rid the construction area of all detectable rodents before construction begins, or as acceptable to the Owner.  Bait all observable rodent burrows.  Install and secure bait stations at regular and appropriate intervals and locations, and document rodent activity (burrows, droppings, bait consumed, dead rodents).  Replenish bait and shift bait stations as necessary to ensure complete control of rodent populations.  Bait edge and accessible bordering areas as necessary to ensure that rodents will not be dispersed by construction activities and that rodents will not infest work areas.

 

                        2.         Maintenance Surface Baiting

 

                                    Establish a maintenance baiting program prior to mobilization by the Contractor, including construction areas and accessible bordering areas, as acceptable to the Owner.  Check bait placements weekly.  Use survey and baiting data to determine the most effective distribution of baiting locations and bait quantities.  Shift and distribute bait and bait stations as appropriate to ensure continued control.

 

            D.        Subsurface Applications

 

                        1.         General

 

                                    For situations involving underground construction/demolition, utility relocation, or utility construction, and for other situations when determined necessary by the Owner or Engineer, initiate subsurface baiting and rid underground environments of all detectable rodents before construction begins.  Assign an identifying number to each manhole and catch basin where bait is placed so that locations of bait placements can be identified and rodent activity (droppings, bait consumed, dead rats) can be documented.  Conduct bait applications during off-peak traffic hours unless otherwise directed by the Engineer.  Access manholes according to the requirements of appropriate agencies and utility companies.  Coordinate the Work with appropriate municipal agencies and utility companies.

 

                        2.         Initial Subsurface Baiting

 

                                    Apply appropriate baits to control rodent populations in manholes and catch basins.  This will involve suspending and securing bait using noncorrosive wire (e.g., 24 gauge plastic coated).  Place bait in all accessible manholes and catch basins within the construction work area.  In addition, bait an appropriate set of manholes and catch basins in the blocks bordering the work area and as acceptable to the Owner.  Identify all baited manholes and catch basins with a standardized paint mark on the street and a numbered tag to be attached to the suspending wire.  Approximately seven days after completion of the first baiting, check all manhole and catch basin baits and record estimates on the amount of bait consumed.  Replenish or increase the amount of bait applied according to the amount consumed or as acceptable to the Owner and Engineer.  Repeat this process again approximately fourteen days later and until there is little or no bait consumed.  Check manholes and catch basins weekly when they repeatedly have 100 percent of the bait consumed.

 

                        3.         Maintenance Subsurface Baiting

 

                                    Prior to mobilization by the Contractor, establish a maintenance baiting program appropriate for the rodent infestation patterns identified during initial subsurface baiting.  This program shall ensure continued control and shall be performed in a manner acceptable to the Owner and Engineer.  Maintain bait in manholes and catch basins that have rodent activity and those that had activity during initial baitings.  Check each bait according to rodent activity levels.  This could range from weekly to approximately every three months, depending upon the recent history of bait consumption. Use utility maps and baiting data to determine the most effective distribution of baiting locations and bait quantities.  Shift and distribute baiting locations as necessary to ensure adequate interception points for controlling immigrating rodents.

 

            E.         Cleanup

 

                        1.         Remove visible rodent carcasses and dispose of them daily consistent with the pesticide label directions and applicable codes, laws, and regulations. 

 

                        2.         Upon completion of any pest control operations at the site, remove remaining bait and dispose of it according to the pesticide label and applicable codes, laws, and regulations.  Also remove all wires used for subsurface baiting and any bait stations or traps.

 

3.4       SANITATION

 

            A.        Prior to construction and throughout the duration of this Contract, identify and document harborage and food sources available to rodents on the construction site and in observable bordering areas.  This includes any littering or improper or insufficient use of trash receptacles in construction areas.  It also includes any bordering areas with sanitation conditions or structural deficiencies that violate City or State sanitation codes.

 

            B.         Maintain records of sanitation conditions in the manner described in Paragraph 3.7 below.

 

3.5       COMPLAINT CALLS

 

            A.        During construction, respond to pest-related complaints from the "adjacent" neighborhood (i.e. within 200 feet of the project limits) within 12 hours when directed by the Owner or Engineer.  Inspect the particular premises and adjacent areas for sanitation and structural deficiencies and also signs of historic and recent pest activity.  Provide sanitation and structural maintenance information to the property owner or manager.  Use pesticides or traps as necessary and appropriate to resolve the complaint when there is a relationship between the pest infestation and construction activities, or when directed by the Owner or Engineer.

 

            B.         Maintain records of all complaints investigated, including location, contact person, inspection results, and actions taken.  Document the relatedness of the pest infestation to construction activities.

 

3.6       GENERAL PEST CONTROL

 

            A.        When directed by the Owner or Engineer, the Contractor shall determine appropriate methods for any pest control task not specifically identified above and shall submit them in writing to the Owner and Engineer for approval in advance.  Such pest control tasks would relate to unanticipated pest control needs within construction areas or adjacent areas.  This could include control of insects or vertebrates other than rats and mice.

 

            B.         Maintain records of general pest control activities and results in the manner described in Paragraph 3.7 below.

 

3.7       RECORD KEEPING

 

            A.        Use standardized data sheets acceptable to the Owner and Engineer to maintain accurate records of date, placement, type, and amount of pesticides or other control tools (e.g., traps) applied.  Similarly, maintain records of surveys, inspections, changes in pest activity, sanitation conditions, and complaint calls.  Submit data in a format acceptable to the Owner and Engineer and as required under Paragraph 1.3 (C) above.
