106 - Acceptance of Work 106.01_National_7_18_2017

Delete Subsection 106.01 and replace with the following:

106.01 Conformity with Contract Requirements.

Follow the requirements of FAR Clause 52.246-12 Inspection of Construction.

References to standard test methods of AASHTO, ASTM, GSA, and other recognized standard authorities refer to the methods in effect on the date of solicitation for bids.

Perform all work to the lines, grades, cross-sections, dimensions, and processes or material requirements shown on the plans or specified in the contract.

Incorporate manufactured materials into the work according to the manufacturer’s recommendations or to these specifications, whichever is more strict.

Plan dimensions and contract specification values are the values to be strived for and complied with as the design values from which any deviations are allowed. Perform work and provide material that is uniform in character and reasonably close to the prescribed value or within the specified tolerance range. The purpose of a tolerance range is to accommodate occasional minor variations from the median zone that are unavoidable for practical reasons.

When standard manufactured items are specified (such as fence, wire, plates, rolled shapes, pipe conduits, etc., that are identified by gauge, unit mass, section dimensions, etc.), the identification will be considered to be nominal masses or dimensions. Unless specific contract tolerances are noted, established manufacturing tolerances will be accepted.

The Government may inspect, sample, or test all work at any time before final acceptance of the project.

When the Government tests work, copies of test reports are furnished to the Contractor upon request.

Government tests may or may not be performed at the work site. If Contractor testing and inspection is verified by the Government, the Contractor’s results may be used by the Government to evaluate work for acceptance. Do not rely on the availability of Government test results for process control.

Acceptable work conforming to the contract will be paid for at the contract unit bid price. Four methods of determining conformity and accepting work are described in Subsections 106.02 to 106.05 inclusive.

The primary method of acceptance is specified in each Section of work. However, work may be rejected at any time it is found by any of the methods not to comply with the contract.

Remove, repair, or replace work that does not conform to the contract, or to prevailing industry standards where no specific contract requirements are noted. Removing, repairing, or replacing work;

providing temporary traffic control; and any other related work to accomplish conformity will be at no cost to the Government.

(a) Disputing Government test results. If the accuracy of Government test results is disputed, promptly inform the CO. If the dispute is unresolved after reasonable steps are taken to resolve the dispute, further evaluation may be obtained by written request. Include a narrative describing the dispute and a proposed resolution protocol that addresses the following:

1. Sampling method;

2. Number of samples;

3. Sample transport;

4. Test procedures;

5. Testing laboratories;

6. Reporting;

7. Estimated time and costs; and

8. Validation process.

If the evaluation requires additional sampling or testing be performed, mutually agree with the Government on witnessing procedures and on sampling and testing by a third party laboratory. Use a third party laboratory accredited by the AASHTO accreditation program. Provide proof of the laboratory’s accreditation for the test procedures to be used. Do not use the same laboratory that produced the disputed Government test results or that produced the test results used as a basis for the dispute.

The CO will review the proposed resolution protocol and may modify it before final approval and execution.

The Government will use the approved resolution protocol test results to determine the validity of the disputed testing. If the Government test results are validated, the Contractor will be responsible for all costs associated with developing and performing the resolution protocol. If the Government test results are not validated, the Government will be responsible for all costs associated with developing and performing the resolution protocol. If the validity of the Government test results cannot be determined, the Contractor and Government will equally share all costs associated with developing and carrying out the resolution protocol.

(b) Alternatives to removing and replacing non-conforming work. As an alternative to removal and replacement, the Contractor may submit a written request to:

1. Have the work accepted at a reduced price; or

2. Be given permission to perform corrective measures to bring the work into conformity.

The request must contain supporting rationale and documentation. Include references or data justifying the proposal based on an evaluation of test results, effect on service life, value of material or work, quality, aesthetics, and other tangible engineering basis. The CO will determine disposition of the nonconforming work.

557.19 Epoxy Repair of Timber Structures.

Furnish epoxy resin meeting requirement of 716.05 of FSSS.

557.19 (a) Preparation for all epoxy repairs.

Action must be taken to remove the damaged wood, arrest the infections, and prevent renewed damage.

Remove all of the decayed sections of timber until sound, unaffected wood fiber is reached. If moisture content of 20 percent or greater is detected the member should be dried before repairs are made. All bonding surfaces must be thoroughly cleaned of all dirt, debris, and excess oil and preservatives.

557.19 (b) Epoxy Structural Adhesion For application and structural bonding of different materials, such as Kevlar wrap, woven E-glass, carbon fabrics or timber hardware. Rollers, brushes, syringes, notched spreaders or caulking tubes may be used to apply epoxy. Apply coats per manufacturers written instructions.

557.19 (c) Epoxy Injection and Consolidation of Decayed Wood For saturation and encapsulation of wood decay, priming damaged areas, and sealing the end grain of new and old wood to prevent future decay. The repair area must be completely sealed prior to epoxy placement. Drill 1/4” to 3/8” port holes close together in the decay zone to provide for better penetration. Ports must be set to allow the injection of epoxy and the displacement of air. Additional ports may be set to monitor the complete filling of the void. Porous and/or checked timbers may require sealing with thick epoxy paint to prevent leakage upon injection.

Injection pressure must be sufficient to completely fill the void without breaking joint seals. Maximum recommended pressure is 40 psi. As epoxy fills the voids in the joint, venting ports begin to leak an even flow of epoxy and are progressively sealed. Apply consolidant repeatedly until the wood glosses over and accepts no more epoxy. The objective is fiber saturation to encapsulate and stabilize any remaining decay.

557.19 (d) Epoxy Structural Gap-Filling of Decayed Wood.

For filling larger cavities and voids in decayed wood and providing structural support. Install size #5 fiberglass reinforced polymer (FRP) rebar a minimum of 18 inches into sound wood and thru the full length of area to be filled. A minimum of two rebar per square foot of area shall be installed. Porous areas to be filled should be primed with epoxy consolidant so repair will adhere to stabilized wood.

Fill large voids (over 1½” deep) in layers to prevent excessive exothermic heat from epoxy reaction. Use adhesive (high-density) fillers or graded siliceous aggregates for structural gap filling. Protect treated areas with clear polyethylene or another type of cover to keep the repair zone warm in cold weather.

716 – Material for Timber Structures

Add the following to Section 716:

716.05 Epoxy Resin Adhesives

Furnish epoxy resin adhesives for epoxy adhesion, injection and reinforcement of decayed wood. Epoxy is used for timber repair as a bonding agent (adhesive) and/or grout (filler) in both structural and semi-structural repairs.
