Project name:
Replacement of Bruckner Expressway (SR) Over Westchester Creek (Unionport Bridge)
Project Description:
The Unionport Bridge is a moveable bridge with a double-leaf trunnion bascule supporting Bruckner Boulevard over Westchester Creek, an industrial waterway in the Bronx, New York. The current project is set to completely replace the Unionport Bridge by constructing two temporary movable lift bridges under existing elevated state structures to divert the vehicular traffic while keeping the waterway navigable, demolition of the existing bridge, and constructing a new twin single-leaf bascule bridge.

Tasks and Duties:
• Monitoring, overseeing, and inspection of various bridge structures including foundations, abutment walls, temporary shoring, concrete, steel reinforcement, brickwork, guiderails and barrier, drainage and sewer structures, and curb and roadwork.
• Inspecting the contractor's work and operation in various aspects of construction and ensuring that it is being performed in accordance with the contract documents, contract drawings and related standard specifications such as NYSDOT Standard Specification, NYSDOT Standard Sheets, NYSDEP Standard sheets, NYSDOT Construction Inspection manual, and Steel Construction Manual. 
• Performing quantity take-offs in accordance with contract documents, estimating and assisting in preparing change orders and directives for extra work, and reviewing monthly CPM updates on the project. 
• Preparing Inspection Daily Reports summarizing progress of construction and calculating payment quantities for installed reinforcing steel, placed concrete, installed drainage structures, paved asphalt, and etc.
• Conducting various plastic concrete testing (air content, slump, and temperature).

It is widely known that presoaked lightweight aggregate (LWA) is greatly beneficial for reducing autogenous shrinkage by providing additional water reservoirs for the mixture. However, in unsealed conditions, when concrete is subjected to drying, addition of LWA to the mixture might not be as effective in reducing drying shrinkage. This study examines the effects of LWA addition on drying shrinkage in different boundary conditions. By varying the number of sides exposed to the surrounding unsaturated environment, the severity of drying condition is altered, and its effect on drying shrinkage of mixes with LWA is studied. The performance of LWA in reducing drying shrinkage of mortar samples is shown to be highly dependent upon the exposure condition and the extent of external curing. The results of this work indicate that curing concrete internally may be an inadequate shrinkage-compensating strategy in a severe drying condition and when no external curing is implemented. Nonetheless, mixtures with LWA exhibited a denser microstructure which can be advantageous in terms of durability.

Shrinkage cracking in concrete is a widespread problem, especially in concrete structures with high surface-to-volume ratio such as bridge decks. Expansive cements based on calcium sulfoaluminate phase were developed to mitigate the shrinkage cracking of concrete. The compressive stress induced due to restrained expansion of concrete has been shown to counteract the tensile stress generated during drying shrinkage. This research attempts to address the differential behavior of fly ash type (i.e., Class C vs. Class F) on early-age expansion and hydration characteristics of ordinary Portland cement (OPC)–calcium sulfoaluminate (CSA) cement blend. It was observed earlier that the presence of Class C fly ash (CFA), unlike Class F fly ash, shortened the expansion duration of OPC–CSA cement blend, which was hypothesized to be correlated to early depletion of gypsum. This paper presents a detailed verification of the hypothesis. Addition of external gypsum to OPC–CSA–CFA blend led to simultaneous increase in expansion and disappearance of a shoulder peak in the calorimetric curve. Thermodynamic calculations using a geochemical modeling program (GEMS-PSI) revealed higher saturation levels of ettringite in presence of external gypsum, which led to higher crystallization stress, and thereby increased expansion.

Calcium sulfoaluminate (CSA) cements were developed for shrinkage compensation of concrete. The expansive nature of CSA-based cements can be used to enhance the resistance against shrinkage cracking by inducing compressive stress in concrete. Because of the higher water demand of CSA cement for achieving full hydration, as compared with ordinary portland cement (OPC), elevated water-cement ratios (w/c) for OPC-CSA cement blends are required for a successful mitigation of shrinkage. This study examines the effects of presoaked lightweight aggregate (LWA) addition on deformation properties of OPC-CSA mortar and concrete as an alternative to increasing the w/c. The motivation behind this work is to promote CSA hydration and increase the early-age expansion of OPC-CSA blends by curing concrete internally while avoiding the undesirable impacts of increased w/c on the microstructure of the mixture. The influence of LWA addition on autogenous and drying shrinkage of OPC-CSA blend was studied. It is shown that the early-age expansion of OPC-CSA blends can be dramatically increased when internal curing is implemented using LWA. Based on thermogravimetric (TG) results, it is indicated that the increase in expansion is partially due to the enhanced hydration of CSA cement in the mixture, which results in an increased rate of ettringite formation. Furthermore, the effects of LWA on total capillary porosity and compressive strength of OPC-CSA blends was also examined to verify the benefits of using LWA to promote CSA hydration as compared to increased w/c.

The application of pre-soaked lightweight aggregates (LWA) as an internal curing agent in concrete to reduce the cracking due to drying shrinkage is thoroughly studied in this report. It is determined that although LWA can significantly reduce autogenous shrinkage, its effect on drying shrinkage is minimal and in some cases it can even increase the drying shrinkage. Moreover, the combined effects of LWA and expansive cement (Type K) and LWA and shrinkage-reducing admixtures (SRAs) on drying shrinkage is also studied. It is shown that addition of Type K cement or SRA to mixtures containing LWA can significantly reduce drying shrinkage and make the mixture more volumetrically stable.
