At HVJ, we do more than simply produce test reports. We make sure you get what you paid for by ensuring that materials perform as intended, and post-construction materials maintenance costs are reasonable. HVJ reliably delivers what is needed when it is required by anticipating and avoiding problems. And, if unexpected problems do occur, we deal with them quickly and directly with project goals foremost.
We assess the proposed fill for a project, ensuring it meets the quality level specified so that embankments, bedding, and backfill perform as intended.
We determine whether Portland Cement concrete provided to the project is of the quality specified and paid for and will perform as intended by field sampling and testing the material delivered to the site. Further, we peform laboratory testing for material strength.
We assess whether Asphaltic Concrete will perform as intended by testing the material during production and coring the placed material for lab testing to determine whether it will have reasonable post-construction maintenance costs.
We determine whether coarse and fine aggregate provided to Portland cement or asphaltic concrete batch plants meets the quality levels being paid for and will perform as intended in the produced material.
We review mix designs for Portland Cement concrete and Asphaltic concrete to determine whether the provided materials match specifications and will perform as intended.
We analyze and assess the testing performed by contractors to ensure it meets the requirements of 23CFR637B for use in acceptance decisions on design-build, concession, and other P3 projects. Additionally, we prepare quarterly reports for FHWA to document verification.
We determine how to reuse onsite soils as fill by specifying the type and proportion of additives required to reduce the shrink-swell behavior to tolerable levels.
We design improvement to the existing soil that sits immediately under a pavement to reduce shrink-swell movement and improve the stiffness and durability of the subgrade through mixing with cement, lime, fly ash, or a combination.
We inspect drilled shaft, driven pile, and auger-cast pile foundations construction to determine whether they will carry the design loads. Further, we check to see that they are the correct depth and diameter and that they are built using proper materials and procedures.
We assess spread footing and mat foundation construction to determine if they will perform as intended. We inspect any required foundation preparations to ensure they are the correct sizes, depths, and thicknesses per the design requirements.
We evaluate whether hardened concrete is suitable for its intended use through field testing or coring and testing in the laboratory.
We test and inspect other construction materials such as masonry, grout, fireproofing, floor flatness, and steel frame bolting to determine whether they will perform as intended and help ensure post-construction costs are reasonable.
