Duration of Project:

• Work Started: January 2010

• Wok Completed: December 2010

 

Steel Configuration

•  Span(s) 21-S to 10-S (12 Spans) – Approximately 350,000 sq. ft. of Painted Steel and Approximately 80,000 sq. ft. of Weathering Steel. Complex steel configurations included: Box Girders, Floor Beams, Floor Beam Brackets, Cross Girders, Diaphragms, Stringers, Upper and Lower Lateral Bracing, Gussets, Cross Bracing, Bearings, Fascia Girders at Weathering Steel Locations.

 

Scope of Work

• Previously Painted Steel: Abrasive blasting cleaning to NACE No. 2/SSPC SP-10 (Near-White Blasting Cleaning) and the application of an Organic Zinc Rich Epoxy Primer, Penetrating Sealer, Epoxy Intermediate and Aliphatic Urethane Finish (Prime Coat, Penetrating Sealer, Intermediate Stripe Coat, Intermediate Full Coat, Finish Coat).  Weathering Steel: Abrasive blasting cleaning to NACE No. 2/SSPC SP-10 (Near-White Blasting Cleaning) and the application of an Organic Zinc Rich Epoxy Primer, Penetrating Sealer, Epoxy Intermediate and Aliphatic Urethane Finish (Prime Coat, Penetrating Sealer, Intermediate Coat 1, Intermediate Stripe Coat, Intermediate Coat 2, Finish Coat). Work also included caulking of edges, crevices and bearings and surface preparation of concrete surfaces to allow for the installation of a waterproof membrane.

 

Project Challenges

• PSE&G De-energizing and re-energizing 4,000 kV high-voltage power lines for the installation of rigid platform and SSPC Class 1A containment without disrupting local industrial facilities

• Utilizing railroad flagmen to install platform and containment over an active Conrail corridor.

• Work within lane closures had to be done safely and quickly to avoid maximum daily penalties of $20,000.00. US Route 1&9 Truck has an annual average daily traffic count 57,000 vehicles.

• Protecting sensitive fiber-optic telecommunication transmission lines and galvanized structure members from damage

• Working in harmony with over a dozen ongoing or scheduled contracts under three different agencies and three cities within two State counties, either within, or adjacent to, the limits of the work

 

Anka opted to install the rigid access platform transverse to the structure, fascia girder to fascia girder, rather than utilize traditional longitudinal platform installation methods. This unconventional approach allowed Anka Painting the flexibility needed to install the platform in available work locations, but not in other inaccessible areas.

 

In all, Anka Painting Co. was able to complete the work on-time, on-budget, and exceed 350 days with no lost time accidents
