Virginia as a "Class A Contractor." If a Contract is for ten thousand dollars ($10,000) or more, but less than one hundred twenty thousand dollars ($120,000), or if the total value of all construction, removal, repair or improvements undertaken by the bidder within any twelve -

bid will not be considered.

(d) The Board for Contractors has interpreted its regulations to mean "a licensed Contractor can

bid on a contract which contains work outside his license classification(s) as long as he subcontracts those items for which he is not qualified to perform to licensed contractors with the

appropriate License Classification and the work of the second party is incidental to the contract." Therefore, the Owner may, as a part of determining whether the bidder is "responsible," require

the apparent low bidder to submit a listing of his subcontractors along with the license number and classification or specialty of each.

(e) The bidder must also place its Employer Identification Number (SSN or FEIN) in the space

otherwise required by law shall include in its bid or proposal a statement describing why the bidder or offeror is not required to be so authorized. A bidder required to be authorized to

transact business in Virginia that fails to provide the required information shall not receive an award unless a waiver of this requirement and of any administrative policies and procedures established to implement Section 2.2-4311.2 of the Code of Virginia, as amended, is granted

by the chief executive of the Owner.

If awarded a Contract, the bidder shall not allow its existence to lapse or its certificate of authority

or registration to transact business in the Commonwealth, if so required under Title 13.1 or Title 50, to be revoked or cancelled at any time during the term of the Contract. Doing so shall be deemed to be a violation of Section 2.2-4311.2 and the bidder understands and agrees that

the Owner may void the Contract if the bidder fails to comply with this provision.

5. BID GUARANTEE:

(a) Any bid (including the Total Base Bid plus all Additive Bid Items) which exceeds five hundred thousand dollars ($500,000) unless waived in the bid documents shall be accompanied by a

George Mason University Standard Bid Bond, Form HECO-10.2, payable to the Owner as obligee in an amount equal to five percent (5%) of the amount of the bid. A Bid Bond may be required for projects having bids of less than five hundred thousand dollars ($500,000) if such

of work, labor or material made directly in the compilation of a bid, which unintentional arithmeticerror or unintentional omission can be clearly shown by objective evidence drawn from inspection

of original work papers, documents and materials used in the preparation of the bid sought to bewithdrawn.

If a bid contains both clerical and judgment mistakes, a bidder may withdraw his/her bid from

consideration if the price bid would have been substantially lower than the other bids due solely tothe clerical mistake, that was an unintentional arithmetic error or an unintentional omissio n of a

quantity of work, labor or material made directly in the compilation of a bid that shall be clearlyshown by objective evidence drawn from inspection of original work papers, documents andmaterials used in the preparation of the bid sought to be withdrawn.

to or perform any subcontract or other work agreement for the person or firm to whom the Contract is awarded or otherwise benefit, directly or indirectly, from the performance of the project for which the withdrawn bid was submitted. The person or firm to whom the Contract was awarded and the

square inch of caliper replaced. This formula is based on tree trunk diameter at breast height. Example: loss of one 12" caliper (same as 6" radius) tree would require replacement with nine (9) 4" caliper trees. [Area of Circle =

3.14 x r2

= 3.14x(62

)= 3.14x(36)= 113.04 sq. in. Assuming 4" caliper trees (same as 2” radius) will be planted as replacements, calculate the area of a

4" caliper tree: 3.14 x (22

)= 12.56 sq. in. Divide the area of the 4" caliper tree into the area of the 12" caliper tree to determine the number of 4" caliper trees required to replace the loss of the 12" caliper tree. 113.04/12.56= 9 trees.]

PART 3 - PART 3 - EXECUTION

3.1 INSPECTION

A. Applicator must examine areas and conditions under which painting work is to be applied and notify Contractor in writing of conditions detrimental to proper and timely completion of work. Do not proceed with work until unsatisfactory conditions have been corrected in a manner acceptable to Applicator.

B. Maximum Moisture Content of Substrates: When measured with an electronic moisture meter as follows:

1. Masonry (Clay and CMU); 12 percent. 2. Wood; 15 Percent. 3. Gypsum Board: 12 Percent. 4. Concrete

C. Starting of painting work will be construed as Applicator's acceptance of sur-faces and conditions within any particular area.

D. Do not paint over dirt, rust, scale, grease, moisture, scuffed surfaces, or condi-tions otherwise detrimental to formation of a durable paint film.

3.2 SURFACE PREPARATION

A. General: Perform preparation and cleaning procedures in accordance with paint manufacturer's instructions and as herein specified, for each particular substrate condition.

1. Provide barrier coats over incompatible primers or remove and re-prime as required. Notify Architect in writing of any anticipated problems in us-ing the specified coating systems with substrates primed by others.

2. Remove hardware, hardware accessories, machined surfaces, plates, lighting fixtures, and similar items in place and not to be finish-painted, or provide surface-applied protection prior to surface preparation and painting operations. Remove, if necessary, for complete painting of


PAINTING 099100 - 5

items and adjacent surfaces. Following completion of painting of each space or area, reinstall removed items.

3. Clean surfaces to be painted before applying paint or surface treat-ments. Remove oil and grease prior to mechanical cleaning. Program cleaning and painting so that contaminants from cleaning process will not fall onto wet, newly-painted surfaces.

B. Previously Painted Surfaces: Prepare previously painted surfaces for new coatings in accordance with paint manufacturer's recommendations. General-ly, remove loose material and attain uncontaminated surfaces. Clean nonpo-rous surfaces with brush or steel wool and appropriate cleaner or solvent as recommended

C. Cementitious Materials: Prepare cementitious surfaces of concrete, concrete block and cement plaster to be painted by removing efflorescence, chalk, dust, dirt, grease, oils, and by roughening as required to remove glaze. Owner or Architect shall approve the painting application of all areas of concrete block that has had efflorescence removed from its surface.

1. Determine alkalinity and moisture content of surfaces to be painted by performing appropriate tests. Provide test results to Owner and Architect for review before proceeding with the work. If surfaces are found to be sufficiently alkaline to cause blistering and burning of finish paint, correct this condition before application of paint. Do not paint over surfaces where moisture content exceeds that permitted in manufacturer's printed directions.

D. Wood: Clean wood surfaces to be painted of dirt, oil, or other foreign sub-stances with scrapers, suitable solvent, and sandpaper, as required. Sandpa-per smooth those finished surfaces exposed to view, and dust off. Scrape and clean small, dry, seasoned knots and apply a thin coat of white shellac or oth-er recommended knot sealer, before application of priming coat. After prim-ing, fill holes and imperfections in finish surfaces with putty or plastic wood-filler. Sandpaper smooth when dried.

1. Prime, stain, or seal wood required to be job-painted immediately upon delivery to job. Prime edges, ends, faces, undersides, and backsides of such wood, including cabinets, counters, cases, paneling.

E. Ferrous Metals: Clean ferrous surfaces, which are not galvanized or shop-coated, of oil, grease, dirt, loose mill scale and other foreign substances by solvent or mechanical cleaning.

1. Touch-up shop-applied prime coats wherever damaged or bare, where required by other sections of these specifications. Clean and touch-up with same type shop primer.

F. Galvanized Surfaces: Clean free of oil and surface contaminants with non-petroleum-based solvent. Provide wash coat if required by paint system man-ufacturer for prepared substrate.

3.3 MATERIALS PREPARATION

A. Mix and prepare painting materials in accordance with manufacturer's direc-tions.



099100 - 6 PAINTING

B. Maintain paint mixing and application containers in a clean condition, free offoreign materials and residue.

C. Stir materials before application to produce a mixture of uniform density, andstir as required during application. Do not stir surface film into material. Re-move film and, if necessary, strain material before using.

3.4 APPLICATION

A. General: Apply paint in accordance with manufacturer's directions. Use ap-plicators and techniques best suited for substrate and type of material beingapplied.

1. Provide access to representative of selected coating manufacturer forobservation of material application only at all times during painting work.Unless specifically indicated by Architect, this representative shall haveno authority to make decisions about the work.

2. Paint surface treatments, and finishes, are indicated in the contract doc-uments.

3. Provide finish coats that are compatible with prime paints used.4. Apply additional coats when undercoats, stains or other conditions show

through final coat of paint, until paint film is of uniform finish, color andappearance. Give special attention to insure that surfaces, includingedges, corners, crevices, welds, and exposed fasteners receive a dryfilm thickness equivalent to that of flat surfaces.

5. Paint surfaces behind movable and permanently fixed equipment andfurniture.

6. Paint interior surfaces of ducts visible through registers or grilles, withflat, non-specular black paint.

7. Paint back sides of access panels, and removable or hinged covers notalready pre-finished.

B. Scheduling Painting: Apply first-coat material to surfaces that have beencleaned, pretreated or otherwise prepared for painting as soon as practicableafter preparation and before subsequent surface deterioration.

1. Allow sufficient time between successive coatings to permit proper dry-ing. Do not recoat until paint has dried to where it feels firms, does notdeform or feel sticky under moderate thumb pressure, and application ofanother coat of paint does not cause lifting or loss of adhesion of theundercoat.

C. Minimum Coating Thickness: Apply materials at not less than manufacturer'srecommended spreading rate, to establish a total DFT as indicated or, if notindicated, as recommended by coating manufacturer.

D. Mechanical and Electrical Work: Paint items exposed to the elements. Do notpaint prefinished items, concealed surfaces, operating parts, and labels.

E. Prime Coats: Apply prime coat of material which is required to be painted orfinished, and which has not been prime coated by others. Recoat primed andsealed surfaces where there is evidence of suction spots or unsealed areas infirst coat, to assure a finish coat with no burn-through or other defects due toinsufficient sealing.

F. Finish Coats: Provide finish quality for new and repainted surfaces as follows:


PAINTING 099100 - 7

1. Pigmented (Opaque) Finishes: Completely cover to provide an opaque,smooth surface of uniform finish, color, appearance and coverage.Cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness,or other surface imperfections will not be acceptable.

G. Tinting: Tint each undercoat a lighter shade to simplify identification of eachcoat when multiple coats of the same material are applied. Tint undercoats tomatch the color of the finish coat, but provide sufficient differences in shade ofundercoats to distinguish each separate coat.

H. Completed Work: Match approved samples for color, texture and coverage.Remove, refinish or repaint work not in compliance with specified require-ments.

3.5 CLEAN-UP AND PROTECTION

A. Clean-Up: During progress of work, remove from site discarded paint materi-als, rubbish, cans and rags daily. Upon completion of painting work, cleanglass and other paint spattered surfaces. Remove spattered paint by properwashing and scraping methods, to not scratch or damage finished surfaces.

B. Protection: Protect work of other trades, whether to be painted or not, againstdamage by painting and finishing work until date of Substantial Completion.Correct any damage by cleaning, repairing or replacing, and repainting, as ac-ceptable to Architect.

1. Provide “Wet Paint” signs to protect newly-painted finishes. Removetemporary protective wrappings provided by others for protection of theirwork, after completion of painting operations.
