1 2007 Standard Specifications for Road and Bridge Construction
2 General Style – Voice & Mood Use active voice and imperative mood for instructions to the Contractor.ExampleOld:Concrete shall be thoroughly consolidated against the faces of all forms and joints, including concrete in a previously constructed lane of pavement, by means of vibrators inserted in the concrete.New:Consolidate concrete against all form faces, joints, and previously constructed pavement using insertion type vibrators.
3 General Style – Voice & Mood Use the active voice for responsibilities of the Department.The Department will inspect the forms.Use the indicative mood when stating a fact.Approximate areas are shown on the plans.
5 General Style – Format Standard four part format for Div 200 to 800 ###.01 Description###.02 Materials & Equipment###.03 Construction###.04 Measurement & Payment
6 General Style – Scope of Work – The Department will make payment for the elements of work described under the “Construction” or “Procedure” subsection under the corresponding Item in the “Measurement and Payment” Subsection.The Department will not make additional or separate payment for work or portion of work unless specifically provided for in the “Method and Measurement” Subsection.
7 Division 100 101 General Information 102 Bidding Requirements and Conditions103 Award and Execution104 Scope of Work105 Control of Work106 Control of Material107 Legal Relations108 Prosecution and Completion109 Measurement and Payment
8 Section TermsIf the term is capitalized, it is capitalized in the SpecificationsContract – includes permits, boring logs, pavement core recordsday – definition unchanged, but use of business day or calendar day has been deleted from the specifications, except where required by State statute.Utility vs. utility – Utility is a company, which provides services/ utility is a facility owned by the Utility.Work vs. work – Work is the entire project/ work is any portion of the Work.RE – term RE replaces Resident Engineer, with few exceptions other representatives with the Department are simply referred to as the Department rather than by unit or division.
9 Section ChangesQuantity Increases/Decreases – bid prices hold only for increases and decreases that are within 25% of proposal quantity. Outside that, prices may be renegotiated.“Proposal quantity” does not include quantities designated on the Plans as “if and where directed.”IF AND WHERE DIRECTED quantities should almost never be used. It can be used with the SME’s concurrence, where we specifically want to insulate the Department from risk.
10 Section 104.03.03 Changes IF AND WHERE DIRECTED items – Fertilizing & Seeding + 10%Traffic Control ItemsPrime CoatTack CoatConstruction DrivewayExcavation, Test PitsTraffic StripesRemoval of Traffic StripesRPMHMA PatchSealing of Cracks and JointsRumble StripsFlexible DelineatorsHMA paving items +10%
11 Section 105.05 Working Drawings Table is provided for which drawings are certified and which are submitted for approvalEnsure that the revised working drawings are submitted to the RE within 30 days of receipt of the conditional certification… The Department will require 45 days for review and approval or rejection and return of working drawingsSpecial Provisions should revise the required # of days to review drawings if the project will have a # of drawings that the designer may not be able to handle.
12 Section UtilitiesContractor required to send all Utilities within the project limits an initial notice when beginning construction operations.Contractor required to provide protection of Utility facilities as required by Utility (Designer’s should identify support requirements identified by Utility in design)Work by Utilities – the contractor is responsible for providing the Utility with advance notice as required in Special Provisions. (Must show durations for utility stages)
13 Section 105.08 Environmental Protection Do not use treated timber products in shellfish areas and other environmentally sensitive areas.Use non-polluting materials such as fiberglass composites in these areas. Before using treated timber products in areas other than those specified in the Contract, obtain the Department's approval
14 Section 106.09 Proprietary Items If material or equipment is specified using a proprietary item or the name of a particular supplier, the Contractor may propose a substitute except when the Special Provisions state that no substitution is permittedDesigners must document the criteria for evaluating a proprietary item
15 Section 108.01 Subcontracting Requirement for subcontractor prequalification with NJDOT procurement eliminated.Technical qualifications can still be identified with the Special Provisions (under the item of work). e.g. segmental bridge, drilled shafts, blasting.
16 Section 108.02 Commencement of Work When a Request for Authorization Form for the New Jersey Pollutant Discharge Elimination System 5G3 – Construction Activity Stormwater General Permit (NJG ) is specified, the Contractor must not perform land disturbance activities until 35 days after the submission of the Request for Authorization Form to the Department (this should be identified on the designer’s construction schedule)
17 Section 108.09 Maintenance within Project Limits Project Limits (area) defined inContractor’s maintenance responsibilities for Project Limits:Picking up and disposing of trash and debrisKeeping the roadway clear of dust, soilMaintaining a safe and unobstructed passageway through the construction area including escape ramps at the edges of pavement.Maintaining surface drainageRemoval of ice and snow from bridge sidewalks open to pedestrian access. – discuss with operations other sidewalk areas for which the DOT has ice snow removal requirement.Must be amended in the Special Provisions, when the project does not involve a fixed area (Operations Service Contracts).
18 Section 108.11 Modifications to Contract Time If excusable noncompensable delays exceed 180 days, the time in excess of 180 days will be excusable, compensable. – Consider amend this to 90 days or less for projects with durations of less than 1 yearExtreme Weather - Time extensions for weather only granted if controlling activity on critical path is delayed due to weather and the cumulative delay due to weather exceeds the number of days specified in Table for any month (Designer’s Progress schedule should be based on normal # days workable for a given month. If an aggressive schedule is being provided – the table may need to be tailored for the project.)
19 Section DefaultFails to begin construction operations within 40 days of execution of the Contract. (Designer should amend this if start of work is restricted)
20 Section 109.01 Measurement and Payment Measurement of QuantitiesMeasured Items vs. Proposal Items. The Department will designate Items as Measured Items or as Proposal Items by having a suffix of P or M in the Item number.The Department will not measure quantities for Proposal Items, except quantities designated on the Plans as “if and where directed,” for payment. The Department will measure quantities for Proposal Items that are designated on the plans as “if and where directed” for payment when the RE directs work using the “if and where directed” quantity.

58 Section 454 Retrofit Dowel Bars For load transfer, for transverse joints or cracks.
59 Section 455 Diamond Grinding Existing Concrete Pavement To improve the ride, friction, and noise qualities of concrete pavement that is not going to be overlaid.Slightly different specification than the requirements for diamond grinding new pavements because larger deviations are expected in the existing concrete.
60 Section 456 Sealing Existing Joints in Concrete Pavement Requires the cleaning and resealing of joints.

Do not place concrete when the ambient temperature is below 20 °F or above 100 °F.
66 Section 504Removal of Forms and Falsework. The Department may require concrete strength tests as specified in the Special Provisions for removal of forms and falsework. Remove forms without damaging the surface. The Contractor may remove forms 24 hours after placing concrete, except for the following:

70 Section 507 Bridge Deck and Approaches Joint AssembliesDeck, Parapet, SidewalkBridge ApproachLimitations of Placing Concrete. Comply with the limitations of placing specified in C, except do not place concrete when the ambient temperature is above 85 °F. If within the 12 hours before the concrete placement the National Weather Service locally forecasts a 40 percent chance or greater of precipitation during the scheduled concrete placement, postpone the placement of bridge decks and pavement.
